Cooler Master / eXtreme Power 650-Watt ATX SATA-Ready PCI-e Ready Supply

Comment:
I design and manufacture cellular electronics for a living. You can not really ask to take apart a module like a power supply to see how it works.. It replaced an old cheapie (25.00) because of need for something of higher quality. This one was louder but probably more appropriate for the HTPC. After a couple of months I noticed wide variations in the MB temp profile. COuldn't figure out why. Then I started to get this annoying squeaking noise from the HTPC (not great when you are watching a movie). Finallly I dismantled the PC and found it was the power supply. I took the PS apart and the fan is defective. It's funny how the last screw says removing this voids warranty! No big deal but what I saw inside is appalling. First of all the power supply is really a 20.00 made in China special. I have not driven this hard and already some of the caps are starting to open and look ready to leak. This one has a build cost (BOM) of < 10.00. If you are looking for a bad power supply with a high price tag and a "cool" name look no further. This one is for you. I dont often completely slam a device, sometimes one needs to understand you get what you pay for. In this case I paid double the price of what I had for something that was of much less quality.for staff - I entered my invoice #2567819 which comes up as invalid so I entered a more recent order

bought this becuase i didnt want to wait for the modular power supply i ordered.apearently it was special order.anyways this one isent bad it was pretty cheap but its construciton is not.though the fan is loud i didnt notice it rite away but now that i have. it seems to be the loudest thing in my case and i have a 900 with all fans at med. i also now have a negetive presure inside the case due to the amount of air this thing spews out of my case so dust is becoming an issue. but overall i cant compain becuase i got it for $50 i think and it does what its suppost to and it matches my case. would recommend

This psu is great value, can't find much that performs better at this price. The plug assortments is good, but it could be better if more of the old IDE 4pin power are replaced with sata power. There are only 3 (or 4 don't remember exactly) sata plugs, and still way too many ide 4pin, although you can get a converter cable it it would be better to have more of the old plugs replaced. One more thing is that it has 2 graphics card power plug, but at 650W it is not very practical to use in a dual card setup.

This power supply operates at a cool temperature and provides a nice stable stream of power (very accurate voltage ranges) and conveniently included the PCI-E graphics card 6-pin connector. You can use either 20pin or 24pin ATX power, and the sleek design of the PSU is also a plus

I bought this for my top of the line custom gaming machine I built.Q6600, 680i Motherboard, 4GB Ram. 8800GT Superclocked and it powers it all great. 650W is PLENTY. Although I'd love to get a 1000W just to say I have one!
