Opening up the Real Power shows 2 aluminum heatsinks which are effectively cooled by the big 120mm Cooler Master fan sitting right on top.





The inside is neatly organized which helps cooling a lot, the fan will operate at ~1200rpm most of the time, but if the PSU reaches 50% load then the fan’s speed will gradually creep upwards until it reaches ~2400rpm at 100%. Only when I put my ear right next to the fan I could hear the air moving through its blades; this PSU is very silent and rated near 20dBA.



Enough with the chit-chat, here are some raw numbers:



Enough juice to power almost any system, and compared to the other players in this business the Real Power stands its ground



You notice that the Peak Power of all the others is considerably higher, however, this high output can only be maintained for a short period of time by the power supply, and thus it doesn’t translate into real world 24/7 usable power. Cooler Master chose to display the actual “Real Power” its unit can deliver, a risky decision but I applaud it. Too many highly rated poor performing power supplies are out there!

For more specifics on the Real Power 450W I highly suggest you take a look at their very detailed product sheet. Here’s a small summary of the things I found particularly interesting and useful for our readers:

Efficiency	> 75% Typically
Output Capacity	450W Continually
Opertaion Temp	0-40°C
MTBF	> 400,000 Hours

Cable Length	24 pin Motherboard Connector 600 mm
	ATX 12V Connector 600 mm
	4 pin Peripheral Connector 600mm
	SATA Connector 600mm + 200 mm
	Display Interface Connector 800 mm
	4 pin Floppy Connector 150mm

Time for some testing I’d say ->
