DeepCool PQ850M (850W) Power Supply Review

Fan Speed
As noted earlier in this review, the DeepCool PQ850M does feature a ‘Zero RPM’ fan mode that basically only utilises the cooling when absolutely necessary. While this is absolutely fantastic for people who value amazingly quiet systems, it did present an issue in our testing. Namely, that when this mode was enabled, the PSU didn’t seemingly deem it necessary to operate the fan once. And this was after running it for more than 15-minutes at 100% load. – While this might sound like a criticism though, honestly, it’s not. It clearly shows that the passive cooling capability of the DeepCool PQ850M is exceptionally good!
With this mode turned off, however, while the fan does operate, it’s still remarkably quiet. It seems to maintain an average of roughly 575 RPM which, even with the added bonus of being able to practically disable this until absolutely necessary, is still barely audible in itself. – Put simply, if you value near-silent system performance, then the DeepCool PQ850M seems like the perfect power supply for you!
