Long Warranty, Amazing/Quality Product, and Platinum Certification!

Reviewed in the United States on September 16, 2019

The Seasonic Power supplies are very nice, It features a 10 year warranty, Fully modular Cables, and a platinum certification. This power supply is of great quality I am very impressed. As this is my first time purchasing a Seasonic product, I am proud to say I am extremely Satisfied with the products that Seasonic Manufactures.

Installation:
The installation for this power supply will vary upon case, But with the Cooler Master HAF XB Evo, it was fairly simple and cables were very lengthy, and of nice quality. All of the Cables plugged in with ease, and fit snug in the power supply. Length of cables is plenty for cases of all sizes, and allows for good cable management. Everything you need will be included in the box, such as some handy zip ties, and Velcro ones as well.

Performance:
Now while this power supply is already quiet, the Hybrid mode will make it change when needed meaning that fan will only spin when it needs too. It's a nice feature to have. On top of all that It is a very nice power supply that is very efficient, and will provide enough power, for a high end system, and future proofing.

Overall: If this is on sale on a good price, I would totally recommend that anyone purchase this as it is a very nice power supply and should be enough for most people. Quality is there, as well, With a 10 year warranty, and a good company behind it, there should be minimal to no problems with anything that may happen. This having platinum efficiency is also another very nice thing to have, as well with the modular cables for cable management for all kinds of cases.

With the market always changing check your options on power supplies, including sales on power supplies, and prices changing by the days. Always check your options. But this power supply, and brand is very recommended by me, glad I gave them a chance!

Quiet; Flexible cables; Cable Ties!

Reviewed in the United States on January 6, 2019

Style: FOCUS SGX (new)Verified Purchase

**UPDATE**
After around 14 months of use, the PSU started having issues whenever 400W or more power is pulled. I filled an RMA and, with a turnaround of a little over a week, received a replacement PSU that's been running fine for a month now. Will update my review if anything else comes up.

Original review below:

I initially purchased the EVGA GM-550 PSU which is a tad smaller and is pretty quiet except the unit I had had terrible coil whine under load. Normally that would be drowned out by the fans of the other components, but my new build uses a EKWB A240G so there only two fans in my entire system plus the PSU. The A240G probably has some seriously quiet fans which means if there's any coil whine anywhere, you're going to hear it loud and clear. So I returned the GM-550 and got the SGX-650 instead and now the only thing I can hear under load are my inner thoughts saying "good job bro".

But in all seriousness, here's a comparison of the two based on my personal experience:

Similarities
1. Both the GM-550 and SGX-550 weigh about the same
2. The fan doesn't turn on until the PSU gets a bit warm (so even under load it will stay off for a bit)
3. Dead quiet when idle
4. Power on self tester
5. 80+ Gold

Differences
1. The GM-550 is smaller by about an inch
2. The cables in the GM-550 are sheathed (not individually sleeved), but the sheath that they use makes the cables very difficult to work with. They don't like to bend or twist at all. The SGX-650's cables look better IMO and are much, much, much more flexible.
3. The GM-550 supported a few less SATA devices but that's expected since it's the GM-550 and not the GM-650 which supports the same amount as the SGX-650.
4. The SGX-650 comes with cable ties! The GM-550 doesn't but has those sticky cable wraps (I don't know the proper name) which can do the job but take up a bit more space and don't look as clean. The SGX-650 also comes with the sticky cable wraps.
5. And finally, but most importantly for me, the model of the SGX-650 that I received did not have any coil whine. Like at all. Is this thing even on?

I know coil whine can be a hit or miss, but if I had to choose between the two again, I would choose the SGX-650 simply because the cables look better and are much easier to work with.

Another solid PSU from Seasonic

Reviewed in the United States on March 28, 2019

Style: FOCUS SGX (new)Verified Purchase

The SGX-650 is a SFX-L power supply, certified 80Plus Gold and 650W, and fully modular. SFX-L is a PSU form factor just slightly larger than SFX: specifically it has a longer depth at 125mm instead of 100mm. This allows room for an internal 120mm fan for cooling instead of a smaller 92mm fan, which is beneficial for airflow and noise. However, because of this longer physical dimension, you must plan accordingly depending on your PC case. Also noteworthy is that Seasonic uses a fluid dynamic bearing fan, so no cheap sleeve bearings here.

Upon first opening the box, you see that the cables and accessories are in their own fabric pouch, and the PSU cube is in another fabric pouch. Everything seems very premium from the get-go. Notably included is a SFX-ATX adapter plate, which allows you to use this PSU in a case that normally only accommodates regular ATX PSUs (more on that later).

I am using this PSU with an overclocked Ryzen 2600X with a GTX1060, all in a Fractal Nano S case. The PSU stays absolutely silent under light use (web browsing, watching Netflix, etc). The fan does not spin until I fire up a game, and when it does spin it's pretty quiet.

The rest of my review will be notes related to my specific use case. If you are planning on using this with the Fractal Nano S, please read on. One reason I purchased this PSU specifically is because a normal ATX PSU gives the graphics card an uncomfortably small amount of clearance. If you use Seasonic's included adapter, your PSU will not sit exactly all the way to the bottom of the case. Seasonic's adapter plate puts the PSU more toward the middle, which does *not* maximize GPU clearance in the Nano S. Luckily I noticed this in advance and purchased a Silverstone SFX-ATX adapter plate separately.

One thing I did not take into account was the length of the included cables. These specs are listed on Seasonic's site, so this was my fault. If you plan on using this PSU in a larger case, measure the length of cable you think you will need. You may need extensions! In the Nano S specifically, the motherboard cable was not quite long enough to route it behind the motherboard tray, so I ended up having to purchase extensions. The included motherboard cable is 350mm long, and the CPU cable is 400mm long. The CPU cable actually *was* long enough, but just barely. I ended up buying an extension for that too even though it wasn't 100% necessary.

In conclusion, I have every bit of confidence that this PSU will last a long time. Seasonic's warranty is 10 years, so they must have a lot of confidence in it too. If you follow any reviews on JonnyGuru, you see that Seasonic routinely crushes everyone else in things like voltage ripple and they often go above and beyond the model's 80Plus efficiency rating. I have no problem recommending this PSU to anyone. Just be sure to do some measuring first.

Wish I'd bought it sooner

I have to admit, power supplies aren't supposed to be sexy. They're supposed to sit there and unobtrusively provide juice to all of the components of your computer, without question. You're not supposed to notice them. When they stop doing that, it's time to buy a new one, right?

So when my computer with a 12 year old power supply started randomly shutting off, I figured it was time to upgrade (it's lasted me through a couple rebuilds). I didn't realize fanless power supplies were a thing until I started looking at power supply reviews (who in their right mind actually does research into power supplies?). The Seasonic brand was highly rated by multiple websites, not just for power supplies with fans, but also their fanless power supplies (although I'd never heard of them before). Also their efficiency was top notch, as well as their warranty. What's not to love? Well, the price is kind of high. I guess you get what you pay for.

And what do you get? An unbelievable silence! I knew my old power supply was the loudest part of my computer, but I didn't realize how loud until I installed the Seasonic. Now I can barely tell it's on. I didn't notice an "electrical hum" like some other reviews complain about (if it's there, I can't hear it above the 500rpm case fan).

It's also much more efficient than my old power supply, which I didn't think was a concern, until I measured the vampire drain. My old power supply constantly used 3-4 watts when the computer was off, so I always made sure to flip the power supply switch to the off position to conserve electricity when I wasn't using the computer. The Seasonic draws less than half a watt when the computer is off (I couldn't even measure it), which is a huge bonus. If you're not in the habit of turning off your power supply, you end up saving 2-3 kWh a month. Not a huge amount when you look at your monthly electric bill, but over the course of the 10-year lifetime of a power supply you're talking $20-50 (depending on the price of electricity in your area). Suddenly that high price tag doesn't look so bad.

Overall, I'm very happy with my purchase, and I highly recommend this power supply.

A quality, semi-modular power supply at an affordable price.

Reviewed in the United States on April 27, 2019

Style: Focus GoldVerified Purchase

I've been meaning to get a modular power supply for a while. However, the ones with decent quality and a gold efficiency rating were a bit more than I was willing to spend.

I saw this Seasonic FOCUS 450 and was ecstatic when I realized it was semi modular, from a highly reputable brand, and most importantly, relatively cheap!

The quality of this power supply is visibly better than the same ones of its type and there is no doubt that it will last.
The 7-year included warranty is also a plus, since there are many stories out there about people receiving power supplies that fail within a few years. Of course, this warranty will not cover your other hardware so just be careful.

One big aesthetic thing that many power supplies in this price range don't have is cables without that ugly ketchup and mustard color. Seasonic went the extra mile to insulate all their wires in this nice black insulation. It definitely refines the look of the rig.

Noise level is often a thing people worry about when building their PCs, I have not heard the fan spin up once (even though it probably has) and I guarantee that your CPU and system fans will be running faster than this PSU fan will ever run.

To sum it up here are the PROS and CONS:
PROS:
- Cheap
- High Quality
- Semi-Modular
- Quiet
- NO KETCHUP AND MUSTARD CABLES!!
CONS:
- Only two peripheral outs

RIG:
Ryzen 3 2200g
MSI B450M Gaming Plus
Kingston 480gb SSD
Corsair Vengeance LPX 8GB

Great PSU with a couple of caveats

Reviewed in the United States on January 17, 2021

Verified Purchase

Since this PSU has no fan, it is completely silent. I was worried that a fanless PSU would make the inside of the case hotter, but the GPU/CPU temps actually dropped several degrees after installing it. Apparently, even without a fan, this PSU generates less heat than the Cooler Master PSU that came with my Omen 30L.

If you are getting this PSU because you want to decrease cable clutter in your case, you'll be disappointed. If anything, there was more cable clutter after replacing a non-modular Cooler Master PSU with the Seasonic PSU. Additionally, the cable from the CPU to the PSU needed to be a couple of inches longer. Actually, when I had the PSU installed by Best Buy (which I don't recommend), they put the PSU in upside down so the CPU cable plugged into the PSU closer to the backside of the case. That was irritating, because according to the instructions, the PSU needs to be installed right side up. After paying Best Buy to install it, I reinstalled it myself with the right side up and was able to get the PSU to reach, but it was kind of stretched. Also, I had to turn the SSD around in the mount (i.e., so the plug-ins on the SSD are facing the backside of the case), because the SATA cables do not have right angle connectors. The way Best Buy installed it (i.e., with the plug-ins on the SSD facing the frontside), the case could still be closed but the cable was smashed up against the glass. Overall, this is a great PSU and if silence is your main concern, I highly recommend it.

Good, hard PSU reviews are hard to come by these days. Seasonic has never led me astray and and can be trusted to utilize quality components. Works well to run a 2700x and 7700xt.

Reviews are blended here, so this is for the SFX-L 650W version; As stated right above this ^.

Probably the best ALL AROUND SFX-L PSU out there. Top performance, average efficiency, then fairly quiet. Even though dimensions are given, it's still pretty cool to see a 650W PSU this small in reality. It has a 120mm Fluid Dynamic Bearing fan which takes up the entire bottom/top, so just look at any 120mm fan and that's pretty much how big it is. If anyone is facing space issues, I'd highly recommend this unit even if your SFF case allows for a full ATX sized one.

I end up using only Seasonic PSU's for their exceptional quality and attention to detail and this is no exception. I use to think their included storage bag was overkill but you know what? Now I expect stuff like that just in case I want to take my PSU out on the town. From the Nichicon hold-up cap, through all the Champion controllers, Rubycon, Chemi-Con, and what looks like FPcap filters, and dual 2x Infineon main switches, not one corner was skimped here.

Reading reviews prior to purchases, I have heard earlier units only had one EPS connector, but mine positively had a dual-headed EPS connector. With SFX usually being used in iTX builds that don't need it I don't see the concern, but it's there now if you want to use this on something that does need two EPS connectors.

I have mine in the pictured Fractal Node 202 and cabling is a cinch. The picture is without the 1050Ti installed for other reviews, but you can see how simple it is by just stuffing it in there. For those that care more, you can separate the ribbon cables, bundle them up into a round bunch and be much more clean...I love ribbon cables for just that ability! Here, I just don't think it matters much with a 65W TDP CPU and separate chambers for the already cool-ish GPU. It's a Blu-Ray player sized case, sorry for no banana for scale.

There's a 450W version a little lower priced but I would pick this 650W version and here's my reasoning. This is a reasonably quiet PSU for it's size up to about 300-350W usage which is perfect for mostly everyone. However, after that the fan ramping/profile is very aggressive which I feel is actually loud. I imagine, but can not confirm, that the smaller model would have a profile just as aggressive and would ramp up to "loud" under even lower loads. Take that with a grain of salt because no normal load really gets above 250W in the normal world and this was found only while benchmarking the PSU and the PC itself where these are extreme pulls. The Corsair, which may appear better on paper is just flat out LOUD throughout the entire fan profile and would not recommend for SFF which end up in the entertainment center.

It's also just above the 88% needed to gain the ETA-A "Gold" but I really feel most of that is just a sales pitch since Platinum is 90% so does that 2% have an RoE? Wanted to mention it because at times I had anomalies that put it riiiiiight at 88.08% that I can't explain. Others got more solid/repeatable results so I call myself out here as being flawed somewhere.

I would buy this again for sure and highly recommend the SFX-L 650W version to anyone looking for a small power supply for a SFF build of any usage. The case had an option for their own PSU which was much lower cost over all, but all problems seem to start at a bad PSU...so piece of mind is worth more to me than dollars.

Got Focus SGX-650 to work in Nano S case without extensions

Reviewed in the United States on March 26, 2019

Style: FOCUS SGX (new)Verified Purchase

I was looking for a PSU that would work best with my Fractal Design Nano S case and two other brands were also under consideration at the time that I went with Seasonic. I had read that for my case, a regular sized power supply could work but extra cable length could get in the way later. I the other two brands under consideration between form factor and power output both had problems mentioned in their reviews and these frustrations were not isolated problems, as many people seemed to have issues that were unresolved or resulted in returns and down time. My primary concerns were first the function of the unit working properly out of the box, and second whether I too may need cable extensions for this power supply to work with the case that I had chosen. Cable Extension prices aren't cheap and for recognized name brands the price would add another 30 or more USD to the price that I paid at checkout. There already seems to be a price premium for small form factor computer power supplies on top of the price premium that comes with fully modular power supplies, and that seems to be true for all of the brands that I was considering when making my choice.

The setup that I went with for this build:
Fractal Design Nano S
ASRock Z390 Phantom Gaming itx-ac
2x8 gb Corsair Vengeance LPX ram
Intel i7-8700K
Noctua NH-D15S with Thermal Grizzly Kryonaut
EVGA GTX 1070Ti FTW2
1 2.5 inch ssd
1 3.5 inch hdd
Seasonic Focus SGX-650 power supply

It did take some work to get the motherboard power cable to connect to the power supply, but all of the other cables seemed to have enough room. I wanted to feed the motherboard cable from the bottom most cable management port to the power supply, but that was not enough length. I had then zip-tied the motherboard power cable down the front of the case after feeding behind and then through the top of the two cable management ports/holes and this worked for a small profile 1060 3gb. When I finally switched out that small profile gpu and put in the full sized 1070Ti I almost gave up on trying to make it fit and was resigned to buying cable extensions until I decided to cut the cable tie to give that little bit of bend/movement to fit card into the pcie x16 slot and lock it down. It worked and I was happy, but had to be patient and there was very little room to make it work just right. I do not think that any other layout would have worked without extensions with the case that I had chosen.

Lastly, I very much appreciated that the small form factor to regular sized psu case mount was included. It would be frustrating to order a power supply and wait for it to arrive, only to find out that you still needed another part to mount the power supply to the case.

I know PSUs fail. Mine had been working fine since 2020. I had a breaker pop while my PC was asleep (which was good safety wise), couldn’t figure out what popped it and when I switched the breaker to the computer room back on the PSU made and incredibly loud noise and stated smelling like burned plastic. Seasonic was quick to respond to an RMA, waiting on the replacement.
