Help with 620w PSU :(

[Deathcore]

Hey guys, i recently bought the corsair 620w PSU for my new BFG 8800 GTX card because i needed more power and PCIE connectors as my older NXZT 500w PSU had none and not enough molex connectors for it.

However when i connected everything up i cannot get a boot or a connection from my monitor to graphics card and there is no power going into my keyboard, i cannot hear any boot noises either.The computer itself all turns on (fans,lights,dvd drives ect). I thought it was my card at first so i RMA'd it to BFG they say its fine. Could i have a faulty psu?.

edit: ( i have the exact same problem as Moogle does on another thread in this forum)


My system is
ASUS A8R MVP mobo
AMD 64 x2 4600
BFG 8800 GTX OC
1 Gig Geil Ram
Fatal1ty Sound Card
1x DVD-Rewriter
1x DVD-ROM
1x 250 GB HD
Corsair 620w PSU

If you got the same probs as me and you followed my thread all the way through then you might have a faulty corsair one. The new one that came is working in my pc right now.

I would try posting the system with only the CPU, memory, and video card installed and, try it outside the case. If this does not work, I'd suggest an RMA for a replacement PSU.

Hey man, you got it from ebuyer right? so did i. How long was the wait for a replacement?.

How do i reset the cmos btw, im a bit of a noob when it comes to this.

Look in the manual and find the jumper for resetting or clearing the CMOS. Pull the power cord from the PSU and move the jumper to the reset position for about 10-15 seconds. Move the jumper back, plug PSU back in, and reboot.

The cmos is like a little blue peice of plastic right? , yeah i removed it before but i didnt put it in a reset position i just took it out, then put it back in the same slot..

No, that little blue piece of plastic is called a jumper block. And, simply removing it will not reset your bios. Find the section in your manual and it will explain the 2 positions.

Hmm i have a query, since my old card was ATI based, i might of not uninstalled all the drivers from it. and coz my new one is nvidia would that be the casue of my comp not getting to windows?.
