Thermaltake w0121RU power Supply 600 wats

HI
I just bought a Thermaltake w0121RU power Supply 600 wats.
http://www.newegg.com/Product/...6817153077&Tpk=w0121ru
I found it on sale at Radio Shack for 50% off and I had coupons that brought the final price down to $36.00 tax included.
Is this a decent power supply? I bought it for a future build and it was a great price.

I read the reviews on in posted on Newegg. The oly con that bothers me is the power supply has a 4 pin cpu connector. Is that something I should worry about?

At 600W it is overrated....at least for a ATX 2.0 supply.

More like a 450W PSU masquerading as a 600W PSU

That unit only has 29A on the +12v, or 348W. It's pretty weak as far as a supposed 600W PSU is concerned. Thermaltake's "Toughpower" branded units are good, but everything else is pretty mediocre.

MMMMMMMMMMM,,,,
I paid less then half price and got half a rated power supply!!!

I was going to use it in a cheap build using a micro atx motherboard with on board audio and video.
No gamer stuff here, just internet music and maybe burning some cd's and photo editing.


How do you calculate the wattage on a 12 volt rail?
If I remember right ohm's law is amps x volts = wattage.

In this case it works out to 348 watts.
Thus 600 watts could be the total output on the power supply.

600W would be it's peak.
500W would be the max.

Well, you paid $36, and good thing you didn't pay more. But if you're using it in a scarcely configured rig, you'll probably be fine.

Yup. Most "modern" PSUs will put out 80-90% of the total output just on the +12v rails. This reflects the evolution of the computer components into using more +12v and less of the other voltages. Modern video cards use +12v pretty much exclusively, and motherboards use +12v to power the CPUs. CPUs and video cards use the majority of the juice in a modern computer. It wasn't that way in the past, which is one way to distinguish between a modern PSU design and an old one.

Actually ohms law is current=electical potential/resistance
