Separate PSU to power my GPU?

[WhyDidYoujustdie]

Hey, I have recently gotten a gtx 480 1.5gb. It is a power hogger! Can I hook a sperate 250w up to it and have the rest run on my 430w?

I only have around 15$ to spend... I was trying to find a way not to spend money. I have;
Phenom II x4 970 BE CPU
Asus m4A79xtd EVO MOBO

2x4 GeForce DDR3 1600Mhz Ram
500gb HDD, 40gb HDD
Cd-rom
And a 430w Power Supply ( don't know what brand.)
And like 16 130w-320w power supplies laying around the house.
Not home but I have a huge case. And I can always cut it if I need to mod the case for any reason. It's aluminum.

Sorry I was in a hurry. I want to hook up one PSU to only power my gpu, and another one to my mobo, and everything else. Thanks. ~CM

There is an addon power supply that newegg sold at one time that did exactly that. Yes, it's possible.

for the price, you may as well buy a brand new psu

Hey there,

While it might be possible, no you do not want to do that. For the same price you could just get a newer, higher quality power supply that can handle the full load.

Why don't you post your full system specs (including case) and we can provide a suggestion?

I gave full specs above.

Just get a new power supply.

I agree, get a new power supply, those dedicated PSU's are a really neat idea, but they just cost to much.

A review of it. There is also ones by other companies that are reviewed.

Hey again ... im sorry but $15 is just not going to cut it to run a power-sucking card like a 480. Good sales appear sometimes that might get you down into the $40 range, but thats the bottom for PSU that you should be using. Its not worth possibly destroying your entire computer in order to save a little money.

This is as low as I would go at the moment:
CORSAIR Builder Series CX500 V2 500W ATX12V v2.3 80 PLUS Certified Active PFC Power Supply -- $39.99 after $20.00 rebate(s)

I'll post back if I see any really good sales.
