    • Works like a champ!
Color: Gold 850 V3
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

    • Great purchase!
Color: Gold 850 V3
Easy to install! I have a Skytech Gaming Shadow Gaming PC, and I asked AI which PSU I should get as a replacement, my old one died, and it recommended this one. Love it

    • Works as described, no issues.
Color: Gold 850 V3
Works as described, no issues. Love that it is modular, which means I do not have tons of loose cables in the case, looking ugly and blocking airflow.

    • Good psu right angled 12v high power a little inconvenient
Color: Gold 850 V3
Had this psu in my system roughly 6 months no issues cool and quiet, but one thing I think people should be aware of is the right angled 12v high power cable this is not compatible with all gpu’s that use this connection as there isn’t a standardized orientation of it so in my case I ended up having to use the pcie to 12v high power adapter provided with the graphics to be able to connect gpu to psu without bending the cables sharply at 180° back down to the bottom of the case. Now this is partially my fault for not looking closely at what I was buying but I doubt many others will either so if you see this just be aware. ... show more
