Cooler Master 550W 120mm LED fan power supply

Thursday, December 8th, 2005 | Power Supply Reviews, Reviews

The Cooler Master 550W power supply is highly specced power supply that doesn’t quite live up to its claims. Unfortunately like many power supplies, this one claims a little more than it can give. In reality it cannot maintain its 550W power delivery for an extended period of time.

It is however, still a decent power supply. It can deliver its claimed power for a while. That’s not too much of a downer, seeing as the vast majority of computers could never put this much strain on a power supply, and even then, not for that long.

It’s basic list of features are…

120mm fan
550 watts of power output
Extra floppy drive sized power meter
Good cooling

At first looks the Cooler Master 550W power supply might not look like much, but a lot should be expected from a power supply in this range.

The blue LED light might not be to everyones liking, but should be fine for most people. You might not notice it if your case is out of the way or has no window on it.

It provides quiet operation due to its large 120mm fan. Basically a 120mm fan can move twice as much air as an 80mm one, but makes the same noise, so you get better cooling, without adding extra noise, which might happen when adding more fans.

A cool extra that comes with this is a meter that tells what kind of output the power supply is producing. It is a moving needle that pinpoints usage along a little dial. Although not extrememly useful and doesn’t pinpoint any specifics of the power output it will provide some eye candy for those who like lots of little gadgets on the front of their computer case.

Their is a 20pin to 24pin converter included with the package which adds a good amount of compatability with motherboards. The cables are fairly standard offerings.

Basically you can’t go too far wrong with this power supply. It produces the said output and will keep things in your system running smoothly for a good long time.
