    The best ... if the cables are long enough for your case ...

    Awesome PSU ... small, silent, cool and powerful! I have 2 of them and plan to get another.The included cables are shorter than with some other PSUs though. Was not an issue in my case but with some larger tower cases, you may run out of cable length

    It is quiet.

    I have an AsRock DeskMeet B660.So no real warranty for me, as I needed to open it and turn the fan around to match my system's airflow.This PSU install may have been the easiest of my life.Motherboard wire, PCIE wire and CPU wires were all that I needed. So, the modular wiring was a big bonus.The cable length would have been perfect an inch shorter for my ITX system, but the length works with the bundled wire ties.It is quiet too

    The only SFX power supply you’ll need

    Superb power supply. Very quiet; I don’t think the fan ever turns on. Perfect for SFF builds. This is a high quality piece of hardware and I wouldn’t be surprised if it lasts for decades. Used it with a Ryzen 7800X3D and RTX 5070. My setup only uses around 50% of this power supply’s capacity when running at full capacity. You won’t need a better power supply than this unless you’re spending over $1k on a GPU.

    Gold standard for SFX power supplies

    This is probably the best power supply available at a reasonable price (~$160). The design is sleek and the cables are high quality and sleeved. It also includes a SFX to ATX bracket to use in larger builds, though that obviously isn't ideal. There is a zero RPM mode for the fan that essentially means the fan will stay off until needed, making your computer run quieter. I would avoid using this with high TDP components, but you can always check this using a wattage calculator. I used an older model of this power supply a couple years ago and the computer still works great. I expect this from t

    Motherboard cable is only 17", too short.

    SFX power supply cables have physically smaller plugs that go into the power supply. The motherboard cable is about 45cm, 17" and is too short!!!!!!!!! Tried buying several different cables/or entension cables. Could NOT find a cable that was SFX, not ATX. At least one of the cables bought said it was SF750x compatible.Corsair does not make a SFX 60cm motherboard cable, nor do they make any SFX mobo extention cables.What a waste of 159.99 +the other cables I tried. HAD to BUY ANOTHER power supply from a competitor to Corsair.

    Item may come opened

    PSU seems to work great. My unit (which I bought new) did appear to be opened and used before though. Had clearly been opened and stuff but everything worked and no cables were missing. Worked great for my cooler master NR200 case

    Best SFX out there. I tried them all.

    I’ve build 3 PCs lately. Used 3 different top brand Small Form Factor PSUs. And I can confidently say Corsair is the best. It’s got the quietest noise level, the smartest design, the best packaging, and the best cables (like by A LOT!)To those who hate the short cable length for a PSU literally designed for small form factor… you’re wrong. I build small form factor and I appreciate when manufacturers keep the cables short. Cable management is a way bigger issue in SFF. So if you’re buying a SFX for a larger build, well… buy longer cables because you’re the odd man out, not Corsair.Buy it. You
