    Reviewed in the United States on August 20, 2016
    This is one of the best performing PSU on the market. I feel confident starting my review with this statement.

    Story:
    I bought this for a mITX build. My case supports normal (ATX) PSUs, however I was curious of how this little guy could perform inside my system. First thing to mention is the quality of the product, it screams high quality everywhere, from the package to the components itself. compared to Silverstone SFX PSUs, I can tell the difference quality-wise, and don't get me wrong, I do like the offering from Silverstone in the SFX market.

    Installation:
    In therms of installation and setup, no problems at all, all the cables necessary are included in the box and this PSU being modular makes it pretty simple to just connect the cables you will be using in your system (everything is coded to match the connectors correctly). Cable management perhaps is the only "con" I could mention, even though "modular" should equals less tangle in cable management, in this case is not that accurate. Compared to a 450w non-modular Silverstone PSU the cable management is more difficult to route between my tiny SG13 Silverstone case, the modular connectors are a little stiff, so bend them doesn't feel natural, I could even think I may broke one of the connectors if I apply too much force on them trying to route them out of the air-flow path of my case fans. The good thing is that if you are like me, needing only a couple connectors in place should leave enough room free for the case to breathe fresh air.

    Performance:
    Silent, works very cool, the fan doesn't even spin most of the times, so you can be sure the noise levels coming from this unit will be near to 0. Temps seems to be fine even with my case components being little cramped inside.

    Playing games for around 3 hours felt natural, heat and noise remain the same as it being in Windows Desktop just idle (to be fair, the only noise was coming from the GTX 1060 cooler). I can tell this PSU can handle my system with ease and I am pretty sure once I feel the need, I will be able to apply OC to the CPU and RAM without any issue.

    My setup consist in:
    I5 6600k stock
    Noctua NH-L9x65 CPU Cooler
    EVGA Stinger MiniITX Mobo
    16GB Ripjaws DDR4 3000mhz RAM
    Samsung Evo 850 SSD
    Zotac GTX 1060 6GB Video Card
    Silverstone SG13 Case
    Corsair SF450w Modular SFX PSU
    Windows 10 Pro

    Conclusion:
    If you are in the market for a new PSU in small form factor, this is a no brainer. Due to the tiny size of SFX PSUs, makes them ideal for cases with little to none air flow, leaving more free space between the CPU Coolers and other components compared to ATX or even SFX-L PSUs.

    I recommend this PSU!

    Reviewed in the United States on December 7, 2016
    This is my first SFX PSU and I was amazed at how petite they are compared to an ATX PSU! Here's my review, by topic:

    CONTENTS OF PACKAGE: This PSU was well-packaged and came with the PSU and a variety of connectors packaged in small velveteen drawstring pouches, along with some small zipties for cable management.

    INSTALLATION: Connected easily into my NCASE M1 with 4 provided screws into the SFX bracket.

    FUNCTION UNDER LOAD: So far my system includes an H170 motherboard, an i3 CPU, CPU HSF, 16 GB DDR4, an M.2 SSD, a 2TB 7200 rpm HDD, an 8TB Seagate Archive HDD, and a slim Blu-Ray drive/burner. The PSU doesn't even break a sweat while powering these, even functioning simultaneously. However, this is using onboard graphics. With a GPU card installed/during gaming the load will certainly be higher although it seems there will be plenty of overhead room left even for a powerful card.

    NOISE/HEAT: The fan doesn't even spin up under the current load. I imagine it would kick in with a graphics card, but with my current load it's 100% silent and produces very little heat to speak of.
    Reviewed in the United States on May 16, 2016
    No noise.
    Except for the fan spinning once on power on, i have not been able to put enough load or heat to turn it on.

    Ran GPU and CPU stress tests (around 204 watts) for over an hour and fan never came on. Was only a little warm after the hour. And that could have been due to heat from CPU.

    Note, i have the intake fan facing up(basically exhaust when fan isnt on) and right under a fresh air vent. Case is 
    Silverstone Computer Case with Mesh Front Panel,Black (SG13B)  with  Noctua Low-Profile Quiet CPU Cooler for Intel 115x Based Retail Cooling NH-L9I  CPU cooler and  Noctua SSO2 Bearing Fan Retail Cooling NF-A14 iPPC-3000 PWM  front fan. Running at 430 and 590 rpms right now(no low noise adapters, just set both profiles to 0% at 30C to 100% at 65C for CPU and MB temps, room is 25C/73F probably). Did not know about this power supply. With the  SilverStone Technology Universal ATX to SFX Power Supply Bracket RL-PP08B  adapter adding around 22mm of height, probably could have gotten a 120mm based cooler like  Noctua NH-L12 Low-profile Quiet CPU Cooler with 120/90mm Dual PWM Fan , not sure.

    Dislikes:
    - The SATA power is using all right angle connectors, so they are very hard to position near each other and also only 4 connectors. If you only have one or two drives not an issue.

    You need 2 PCIe 6pin(peripherals), 3 ATX/CPU/EFS 8pin(cpu,gpu)(not 8pin PCIe) and 1 ATX 10pin plus 1 ATX 18pin(motherboard) female connectors on the power supply side to make your own set of cables.

    Last note, does not come with ATX to SFX adapter plate. Glad, since I found the Silverstone adapter that is much better design than Corsair's adapter.

    Great power supply for my m-itx, SFF, HTPC. I upgraded my HTPC to a Ryzen-5 and AMD graphics card that required upgrading the original 300W SFF power supply to 450W. Corsair is known for their reliable products and this power supply did not disappoint. The power supply fit perfectly in my tiny Silverstone case and the modular cable feature is a BONUS as it increased my space as the unused cables were left in the box. My only issue was the 12V power cable was a bit short (about 2 inches more would be nice!). I was able to connect but the cable didn't follow my original planned design and instead is a straight shot from the PS to the board.

    I used this in a build with a Phanteks Evolv Shift Air case. The PS fit perfectly, was easy to install and is super quiet. More than enough power for my needs. Came with everything I needed.

    Reviewed in Canada on November 17, 2017
    This is my first SFX power supply and I am quiet pleased with it. The fan hardly ever spins aside from startup so cooling isn't an issue. It provides plenty of my power for my living room gaming PC. My only complaint was I wish the cables were longer and a little nicer. It didn't bother me a ton though since my build is all enclosed and quiet small.

    No se como lo han logrado, pero Corsair se ha sacado un 10 con esta fuente: es diminuta, silenciosa y muy eficiente.

    El ventilador ni siquiera se enciende si el sistema no se está usando de manera demandante, característica que la hace en extremo silenciosa y en caso de encenderse, no hace mucho ruido el ventilador. Es una fuente de poder, así que no puedo agregar mucho más, pero si les puedo decir que si están buscando una fuente SFX de gran calidad, este producto es excelente.
