Ok Strange problem I recently bought an ATI 5870 which when I plugged in didn't work for ages even when I bought a new 750PSU then someone suggested not plugging in everything & see what happens so I did & through a process of elimination I found out that when ever I don't connect the PSU to the CD ROM drive everything works.
The PSU is a good one it Thailand made because I live in Thailand but I been told its good... but I only have 1. Hardrive & 1.CD ROM Drive... so even if with a rubbish 750w PSU it should still be enough power...No?
Also what would happen if you plugged in a insufficant PSU into a super computer? Because my when I plug in the CD ROM drive it doesn't even boot past the Dos Screen
