Dead PSU?

post #1 of 6
Thread Starter 
So basically my friend bought a new PSU and wanted me to put it in for him cause he wants to buy my 9800GT. I connected it and everything, the cords are in the correct holes. But when I turned it on it turned on then off extremely fast. Now it wont even turn on. We plugged in the old PSU and the computer works perfect with it. Is it just a crappy PSU or what? Thanks in advance! PS this is the powersupply. http://www.newegg.com/Product/Produc...-001-_-Product

Because it's a piece of crap. Since it's clear you don't even have to open it up to see how crappy it is. See those three transformers down the middle? Means it's a half bridge design, which means that it was designed around the turn of the century for Pentium 3 era systems. I bet you it can't do more than 250W, and the instantaneous startup load is probably too much for it to handle (though it's probably less than 250W). I bet its +12V rectifier isn't rated for more than 14A, likely less.

Ohhh ok. Thanks. But why do you say it can only do more than 250w if it's a 500watt?

Because companies lie. Lie through their teeth. I've seen 680W units that blow up (frying whatever's connected) at 250W. Most crap generic power supplies fail around 200-350W no matter what the label claims. This is just a crap power supply in a rather tasteless, goofy housing.

Alright thanks a lot. I didn't know any of that stuff. I'll check it out.
