Cooler Master Real Power M850 Power Supply Review

[RobRich]

Quote:

Cooler Master markets their Real Power M850 as "World's first power supply with six 12V rails". While this may sound good on paper I couldn't see any big advantage of this during my testing. Actually the actual peak power of all six 12V rails is 768W, which means that each rail is only good for ~11A if you use all six. Yes, the 12V line is quite stable, but there are more stable power supplies that use four or less rails. The 3.3V and 5V lines were among the worst of our test group, but this doesn't mean that the line stability is bad. It is just that there are better power supplies out there. The same goes for efficiency and fan noise - good, but we have seen better results.
