HD2900 Power Question

post #1 of 13
Thread Starter 
I'm getting a used HD2900XT soon,
it is a ASUS one,
it has a 6pin power and 8pin power connector and the 8pin is said to be not neccessary unless I want to use overdrive

so question isl
if the video card takes power from the 6pin as well as the PCIE Slot,
or only from the 6pin
and does it take more from the 6pin or the PCIE?

Both PCIE slot and 6 pin Power. It requires 550W for a loaded rig with one 2900xt so your PSU may barely make the cut.

I couldn't tell you how much power the slot gives but you have to run 2 6pins or your machine wont even boot. I have that card in my other pc.They do have a little mod you can do for the 8 pin tho

that does help me abit, I'm kinda looking for that answer too
but the main thing here is the PSU,
as reviews recommended
a 550W PSU is best,
I do have one , but not brand named
and Currently have this setup
but note that there's been a update since that vid, all mobo related goes to 500w, and everything else (including case fans etc) is on the 200W right now.

and I cannot afford a PSU until I sell my spare motherboard
