The funny thing is the motherboards that people are hooking these to don't need 7 amps on the 12 volts. The +3.3 and +5 are the bottle necks, even on a Pentium 4 application. Plus, I wouldn't trust this thing with a pentium 4 VRM in a car.

You know the stereo recievers that have an outlet on the back of them that is switched with the main power switch? This is like somone saying the 300 watt stereo reciever is 2000 watts because the outlet is rated at 1700 watts and the stereo is rated at 300. FALSE ADVERTISING.

This thing doesn't do anything to the 12 volts, it just lets more of the input go to the output. It doesn't regulate it filter it or anything. Just turns it on or off.

I bet no one has done any thermal testing on this thing at 7 amp draw on the 12 volts. That Mosfet is suppose to be soldered down to a board for heat sinking. Looks like they are relying on it not generating any heat. It is a good thing most people who buy these only drive a 1000 dollar car..

i'm not afraid of the big bad soldering wolf, i removed the regulator and had a look.
the part number on the reg ic is [B]FU5305.
before you ask i had a quick look, i dont know where he's getting these reg ic's from i cant find a cat no anywhere, could be importing them russia or somewhere......
anyway that's what he's using, so now you can all go ahead and get the pw-70a's and start sticking your own reg ic's in if you can find them..??

and yes he does a messy job at soldering them in, he needs to go back to school..
