i got an 5870. i got one 400w and another 400w psu. One psu give power to hdd, modercard, processor (one hdd and a dual-core 3.0Ghz). The other one has 3 power things and the card requires 4 is it ok to connect same card to 2 different PSUs? Btw i dont want my card to blow up!
3 power things? can you be more specific? Is the 2nd 400W a dedicated powersupply for video cards? Or are these 2 normal PSU's? DO you currently have them both hooked up and running a graphics card?
My opinion is, if you are going to spend $400 USD on a video card, get a real PSU to run it. For $80 you can get something that will do what you need and be safe about it. It sounds like you want to use a cheaped out power solution to run a high end card. Not a good idea.
The 400W Corsair is a nice PSU but won't handle the 5870. I am assuming you mean 3x 4pin molex connectors. My assumption is that like PSU won't be able to handle the current draw. I wouldn't chance it. The worst thing you can do is not have enough power. It puts a hard load on the components.
Yup, u will better with a single powerful PSU, u can buy an expensive GPU but u can't afford a "cheap" high quality PSU?
Don't take a risk, u have a great GPU on your case...
i got 2 PSUs and im going to buy like a 850w next week, the question was can i use 2 psu to same graphic cards or is that a stupid thing to do (different voltage and ***?) - if i dont want my 5870 blown up?
