Cooler Master V850 850W Modular Power Supply Review

Final Thoughts I've always been a fan of Cooler Master power supplies. It was Cooler Master's Real Power Pro series that really made me go, "Wow!" when I first opened the box up.

– Quality components; – SOLID 12V rail; – Under 1% voltage regulation on all of the rails; – 100% modular; – 5 year warranty; – 80PLUS Gold certified

– None that I found

This is a very good PSU. It looks great, I especially like the rounded metal around the modular connectors instead of the standard sharp edges. It's quiet up until high heat high load, which is nice. At full tilt the fan isn't the quietest, but it's not the noisiest either.

Worked for me

Bought to replace a failed OCZ ModXSTREAM-Pro 600MXSP 600w PSU, it seems to have done the job successfully. Chosen for its high efficiency and relatively large capacity as part of a workstation supporting an AMD Firepro W7000, it has proved to be a satisfyingly quiet running unit.

Standby Voltage Failed Had To Return

I bought this hoping for peace of mind in a new PSU, instead the standby power was faulty from the start, with longer and longer delays in standby power to the motherboard becoming apparent.
