Ati HD 5850 and Power Supply

[feroc1ty]

I was wondering if you guys think that this power supply, http://www.newegg.com/Product/Product.aspx?Item=N82E16817139004 , could run my rig.

I have an i7920 cpu, 1 720gb hdd, ati hd 4850, 6x1gb ddr3 , 1 dvdrw.

I wanted to see if that PSU would run that rig with the new hd5850 instead of the 4850.

Those two units are very good for the price and have higher wattage.

Thats more than enough, 500 watts is minimum

I had a 430 watt power supply and i thought it would try the 5850 which says on the box that it need 450 watt with one 75 watt pcie adapter. Turns out you actually need two pcie adapters to boot. So I upgraded my power supply to a RX630Z with two pcie adapters and 630 watts. It has the crossfire logo and everything.

I can connect everything now, but it sounds like it is still short of power since the fans don't fully power up. It actually got past the POST once when i had a wire stuck in the video card fan. I'm really not sure what to do now.

I guess I have to trade in this power supply for something that specifically says 75 watt pcie. This is very frustrating...
