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.

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

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.
