Works well. I went Overkill but that's what you need really some future proofing and it fits in the fractal design mood case the cables it gives you it's fully modular work very nicely if you had a bigger case maybe you need some extenders but I didn't also the fan never turns on but I understand that it's by Design so I try not to worry about it ... show more

    • High price, but quality...
Size: 850W|Black
Lovely small form factor piwer supply that brings the juice for a moderate and medium tier build. 850Watts is a good plateau before you start to kick higher prices for more power draw. It's quiet, keeps cool, and works well to add a small extra rgb color on the back side of my pc, while i don't see it during the day, i do notice the glow at night. ... show more

    • Best SFX psu on the market
Size: 850W|Black
By far best psu I have owned. Noise level is unnoticeable When in use. Bought used to save money and when it arrived it looked new like it had never been used before. Highly recommend for SFX-L PC build.

    • Seems decent, no screws included
Size: 850W|Black
Only used for a few days so far, seems like a decent PSU. Needed to install in a full ATX slot, the included bracket fit perfectly but there weren't any screws included to attach it. Thankfully I had a few extras laying around that fit from a previous build.

    • One of the best SFX PSUs I've owned
Size: 850W|Black
Rebuilt my PC into a smaller case while upgrading to a 4080 super, and noticed my EVGA SFX 850 had serious coil whine and the shortest cables I've ever seen (made it impossible to cable manage). Ordered this guy as a replacement for its ratings/classifications and knowing the cables are sleeved and the perfect SFF build length. 9/10 product - just wish it came with cable combs so I could clean up the sleeved cables a bit instead of using zipties. No coil whine, no power draw issues, super quiet fan, and the cables are extremly nice and flexible. Running a i7-13700KF and a MSI 4080 Super Expert with zero issues. ... show more
