Cooler Master Real Power M850 850W

[W1zzard]

Cooler Master's Real Power M850 power supply is one of the first power supplies that has six 12V rails. This should be enough power for all your SLI or CrossFire needs. Like many other PSUs today, the M850 comes with a high gloss reflective case and a large number of connectors.

How come they call this the first PSU with six +12v rails when there already are PSU's such as ABS-Tagan ITZ-1100 that come with 6 rails (and released more than an year ago)?

My zalman also has 6 rails and it came before...

Well, the Zalman and Cooler Master both have 6 +12V rails because they're both from Enhance and their high output units just have 6 +12V rails. So that's hardly something for Cooler Master to brag about.

Besides that, there were Topower 1000W+ units with 6 +12V rails long before Cooler Master, Zalman, etc.

Regardless of who was first, I do commend them for going with 6 +12V rails. By doing so, you can limit how much power is delivered to a connector in the event of a short, but have fewer connectors on each rail so it's very unlikely to ever overload a rail.
