[SOLVED] New PSU Issues

Stevie_Mac · 03-31-2012, 07:00 PM

I currently purchased a new power supply to replace the old one since I was upgrading my graphics card. The old PSU is a 20+4 the new one is a 24 pin. I can plug the 24 pin right where the 20 pin plugs in but leaving the atx12v 4 pin connector on the motherboard open. The issue is when I do this it seems the only thing getting power is the graphics card and the fans. I don't see anything post since there is no video output. Also, it doesn't seem as if the hard drive is turning on. I've tried one other PSU that I have that I know is good and I get the same response with and without power running to the graphics card.

This needs to be connected. Depending on the Power Supply you may have a 4+4 ping connector for this.

Connect the 24-pin ATX and the 4-pin ATX Power connector.

Stevie_Mac · 03-31-2012, 07:25 PM

thats just it. its only a 24 pin I don't have an extra 4 pin connector for the PSU

makinu1der2 · 03-31-2012, 07:26 PM

It has an 8-pin. You should be able to detach the other 4.

Stevie_Mac · 03-31-2012, 07:27 PM

So your saying I need to connect it to the motherboard as a 20 pin then the 4 in the atx 12v? If so I don't have enough cord for that

Stevie_Mac · 03-31-2012, 07:28 PM

and why did the original power supply work that was a 20 + 4?

Could this solve the problem I'm having?

Whether 20+4 or 24-pin still the same. You still need to connect the to the 4-pin ATX power connector on the motherboard.

You new PSU just has a 24-pin and 8-pin ATX power connection. It will still work if connected properly.

Not needed.

You have all the proper connections needed with the new PSU.

The CX-GS-M Series Corsair are lower quality and not recommended.
