The Cooler Master V850 850W Power Supply is an outstanding product that comes with a quiet 135mm fan, is 100% modular and performs brilliantly. The peek output of the 3.3/5v rail is 125 watts and the 12v is 840W watts.

I have used this power supply for a year now and had no problems. like the modular part of it, only have to use what i need to power the stuff I have in my computer.

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.

This a very good power supply. Don't have to worry about having all the cables installed, just use what you need. and is very quiet too. very happy guy here

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

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.

Expanding upon the success of the V1000, Cooler Master's V850 brings the same performance to the table, but with a tad less power.

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.

The CoolerMaster V850 has excellent voltage regulation in the 1% variance range and an efficiency of above 90%. This Power supply truly deserves a Gold Rating.
