Seems it doesn't have a 8 pin connector. You will have to either use a molex adapter like KILLER_K suggested or change your PSU.
Molex to 8 pin adapter.

Yes that's your EPS/ATX power connector. So you don't have one for your GPU and will need a new PSU or the molex adapter.

Just put it together yesterday. Cable management is at the bottom of my priority list.

I tried using a 6 pin in the 8 pin adapter to see what would happen because I was curious, and It powered on, but while installing the drivers it didn't recognize it. Got me hopeful for a little bit.

The GTX 580 requires descent power on the 12v rail... This PSU has a dual 12v rail and people seem to be having this issue with a gtx 460...

This is a $36 PSU on Amazon... that says it all...

yea..i know. i had a crappy psu too but it worked with the adapter. my problem was the psu got loud under load so i sold it in an older sys and bought a corsair 650w for the 580.
sure i´d never buy a cheap psu again but maybe he got luck and his psu will do the work with the adapter. thought an adapter for some bucks might be worth a try..

yeah I agree it's worth a try... Good luck op and let us know how it goes!
I saw on another thread that you tried it with just the two 6-pins... SMH...
Please wait as you could possibly damage your new 580...

Jeez an 880w PSU that only has dual 6 pins? Sounds like a 400w PSU to me.
