80 PLUS Gold-certified efficiency

The super-efficient operation of the CS Series Modular results in lower energy use and lower operating costs. Since it generates less heat, the fan doesn’t need to work as hard, and you’ll enjoy near silent operation.

Soild construction, quiet fans and modular connections!

Reviewed in the United States on October 15, 2015

Verified Purchase

I purchased this after receiving a Sentey 550 watt model that was DOA. Amazon was great, as usual, about the return process. I decided to step up to 650 watts, just to be safe. I'm glad I did because the video card (R9 390X) I'm planning to upgrade to uses quite a bit of power...which this PSU just barely meets the requirement. A 750 watt would be a better option, but I'm going to make due with this one for now. I'll be updating this review once I install my new gpu.

So far, this PSU has been great with my current gear. It is inaudible to me, over the case fans, so no issue there. Being mostly modular (minus motherboard power) makes for a neat wiring job. I had no problems with any of the connectors, everything snapped into place perfectly. This PSU is apparently a step up from the CX series....which seems to get mixed reviews. I would recommend this PSU to anyone wanting a great product from a solid manufacturer.

The best PSU for good gaming rig.

Excellent performance so far, good low energy use and consumption. The package included a lot of cable ties, extensions for all cables and nice organization. Fits perfectly on my micro ATX case (xps 8500) and doesn't weight that much either. Perfect for a decent gaming pc build, my specs are:

i5 3450 3,1 Ghz OC 3,4 Ghz
MSI Gtx 970 OC 1400 Mhz
8 Gb RAM (gonna upgrade soon to 16)

Note: the PSU fan is at the top of the box as you can see in the image below, I don't think it affects that much but if you have the same case as me just turn it around before installing, I'll update if I change it or something goes wrong.

good powersupply the 24pin cable isnt removable and it is very long and very thick making it hard to cable management. also it comes with only 1 8 pin slot for your GPU you can use the splitted 8 to 2x 6+2 cable but its ugly and not for powerful GPUs.

Reviewed in the United States on November 17, 2016

Verified Purchase

Wonderfully quiet. As with most of the new Corsair PSU's the fan does not run unless the computer is at full load making this unit extremely quiet most of the time.

I purchased the 650 (over a 550 or 500) so I would have the extra power and cables for use in the future when I add a second video card and go SLI. If your video card uses only a single 8 pin connector for the cooling fan you will not need the extra cables of the 650, and could probably use a 550. My Video card, the MSI GAMING GeForce GTX 1070 8GB GDDR5 DirectX 12 VR Ready (GeForce GTX 1070 GAMING X 8G) , takes the normal 8 pin and an additional 6 pin. meaning I needed the extra cabling and power for a future SLI setup.

Be warned, most cases now put the power supply on the bottom with the intake fan facing down. So if you have carpeting you will need a hard flat surface to place the computer on, so the intake will not be blocked.

This is a Semi-Modular unit, meaning the cables for the Motherboard which every ATX computer will use, are hardwired into the power supply. This is only a problem if you need to remove the PSU, as you will need to unplug and unthread the cables to remove it. If you are someone who frequently trades parts you may want a fully modular power supply, if you are going to build and forget, then this power supply is a great choice.

My husband and I received a PC from a friend who had upgraded, but he mentioned it would need a new power supply. We hesitated to purchase one, as they can be quite the expensive investment! We found this product, with great reviews at a reasonable price, and decided to give it a try.

The fan is wonderfully quiet! We are gamers who play some demanding video games, but the fan never seems to have a hard time keeping up! Runs like a champ! It was very easy to install with the cables it came with. We loved the modular design, allowing us to not have a bunch of unnecessary cords hanging in the PC tower. Definitely would recommend to those needing a power supply on a budget. It's been going strong for months now, and I wouldn't doubt we won't have issues for a long time!

Reviewed in the United States on April 22, 2015

Verified Purchase

An excellent product! I purchased this to replace a PSU of dubious quality before doing other, power hungry upgrades. The modular design and sleeved cabling help keep cable management sexy and airflow unobstructed. Coil whine is nonexistent, and the fan noise is basically inaudible even under prolonged, heavy workloads. It DOES have a fan that does indeed spin, so a silent PSU this is not. However, to put the unit's noise into perspective: I run Noctua NF-F12 iPPC fans on my system, and as quiet as they are, they drown out the sound of the PSU.

Good Value PSU From A Good Quality Brand!

Reviewed in Canada on January 18, 2017

Verified Purchase

So far I have to say I'm happy with this power supply. Traditionally I've gone with EVGA 80+ platinum PSU's, but for my latest ITX build I wanted a smaller power supply, and I did not a whole bunch of extra sata or vga cables / power plug-ins on the power supply itself; that I would never use. This semi-modular PSU delivered what I had expected. It came with the motherboard and CPU cables already built it and I only had to attach one vga and one sata cable (more cables are included). If I had to be picky I'd complain that the motherboard cable shows the colorful wiring right at the end where it plugs into the motherboard itself, and the rest of the cable is sleeved. But at this price point for a semi-modular 80+ gold efficiency PSU I really can't complain. All the included extra cables are black ribbon cables, so they don't look ugly and stand out. All in all it was a good valued purchase and Corsair is a trusted brand.

Feb 10 2015 - one month since installation. product is working as expected. very easy and clean installation. operation is silent.
i bought a PC with a crappy power supply, it reboots without warning. i did some research and found out that it may be due to the substandard power supply. Then i came across this power supply from corsair, its not the high end stuff but its not low end either. I decided to give it a try. I did some gaming, rendering and so far the power supply was ok under heavy load.
will update this review as time goes by. So far this product satisfies me.

Runs very efficiently and is super quiet and cool always. The modular design is great and it isnt too bad on power consumption either. My favourite part about this power supply though is that it didnt immediately blow up my computer like some of corsair's lower end models have in the past.
