So basically i have this power supply http://www.newgeardeals.com/index.php/review/product/list/id/226/ and I am having complications running this XFX 4850 http://www.newegg.com/Product/Product.aspx?Item=N82E16814150351. Now I have posted this in the GFX card section but I decided to post it here now that I know its more of a PSU problem.

The problem is the adapter wants you to connect it to two sources and I can only find one on the PSU (Yes there are 4 6 pin PCI-E slots but when I attempted to run it using that it lasted 30 seconds in any high performance game). I also further read the instructions saying I have to connect the adapter so I need to find another connector. I found one that had a yellow, black, black, red connector that had P17 on it and looks like the correct one o and I found another with red, black, black, blue and yellow mixed cord (this one doesn't seem to work) that said P7 on it.

Is this an issue with plugging it in or is the real issue the Amperage? There is no overheating and it only freezes with High end games so I'm assuming its not receiving the power correctly or there's not enough energy being sent.

I'm running out of things to try :( .

Is it a new card ?
What did it replace if it is ?
An Nvidia card ?
Did you completely remove the existing drivers and run a driver cleaner before installing it ?
What high end games ? Just BFBC2 or others as well ?

Is there any chance that you could try the card in another system ?

New? Well I bought it 8 months ago but it had the same problem, so I just put my old one back in until it died yesterday. It's basically unused.

Replacement? A Radeon 3870 512 mb

Yes, I ran it in safe mode and did all the uninstalling and removing of drivers.

BFBC2, MW2, Mass Effect 2, Starcraft 2, Team Fortress 2, Left 4 Dead 2. Those are pretty much all my games I play.

Nope, this is the only computer.

There's about 2 amps power difference between the 2 cards, your power supply can handle 2 cards that use even more power than either of the ATI's.
You should have looked into returning the 4850 8 months ago.

Well its a good thing the 4850 isn't that expensive for me (found one for 120$).

I should have done it a long time ago but I'm just glad its not my PSU's fault. That would be harder for me to replace.

Edit: What are the other 2 cards higher that it can handle?

It should be able to handle any card made.
What I meant was that the system ( XPS 7xx w/ 1000w psu ) was available with two 8800 GTX Ultra's in SLI.
Power consumption of a single Ultra is 3 to 5 amps greater than a 4850.

I see... well I'll either get another 4850 or 4870. Hope the same problem does not persist.

Well it seems my computer crashes even if I'm surfing the web. Although it took like 2 hours before it crashed. Does this mean anything else?

Really don't know.
You say there's no overheating, does that include the cpu ?

CPU is at 19 C which I think is pretty cool.
