    • Good PSU
Size: ATX Compact
I've always had good luck with Cooler Master PSU's and this one continues to perform. I installed this in a new Ryzen 7 build and it works great. Ample cables that are long enough and have enough connectors for most purposes. I have no complaints.

    • Works like a champ!
Size: ATX Compact
Installed the PSU and everything works great. I can't believe how silent this thing is. The fan doesn't turn on until you're stressing your computer, so the majority of the time, it's as if the thing is off. Doesn't bother me too much as I have mine shoved in a closet, but I can still hear the difference. I have 10 hard drives, a 4070 super, and a 5700x all connected to this. I run OpenMediaVault (which is debian 12) and have a windows 11 virtual machine powered on at all times and pull atbout 115 watts at idle... silent. Even when i play some games, I pull about 250 watts or so, and the PSU is still silent. I can't speak on the longevity, but the fact that it has a 10 year warranty definitely leads me to believe it'll be durable! ... show more

    • Quality power supply
Size: ATX Compact
Solid and stable power supply, modular cables give you everything you need and nothing you don't. No problems installing. Quiet fans and optional power mode. Runs 9700x3d CPU and 4070ti with no problem.

    • Received open box with missing cables
Size: ATX Compact
I was sent a clearly already opened box with half the cables missing. And I see others in the reviews had a similar experience. What a waste of time and energy just for me to have to return it immediately.

    • Quiet & Hard-working!
Size: ATX Compact
So far, this PSU has not failed me. I’ve had it running for a little over a month, and I never hear it, which is a great sign from a power supply. The moment you start noticing your PSU, you are probably in trouble haha.

    • Good quality!
Size: ATX Compact
Good quality and fitment. The main fan opening accepts two sizes of fans.

    • Great, but mind the power cable
Size: ATX Compact
The connectors were all compatible with my build, and haven't really heard the fan much yet, so overall a good PSU. One thing that set me back is the incompatibility of the PSU's power cable with the power outlets in my country, with it being too weak of a cable(125V max capacity) for the 220V outlet, and got fried pretty quickly after plugging it in. Once I bought a new power cable everything worked just fine so if you need to replace the cable for similar reasons, know you absolutely can and it will be compatible with this PSU. ... show more
