I'm not sure if this is right question for this site, so I apologize if I shouldn't have asked this here.
I have two 400W (labels say that they are 400W, but I think they are much less because they weren't made by known brands) PSUs. I also have bought ATI Radeon HD4870 graphics card. I think that just one of these PSUs is too weak to power whole computer, so I thought why shouldn't I connect one PSU to power graphics card, and other to power everything else ?
In theory (or at least in my head) that should work :D Now I'm asking you if this is something that I should do? Could there be any complications/problems ?
If I can do this without killing every piece of hardware that I own, my next question is: how do I do this ?
This is what I think I must do. Please correct me if I'm wrong (actually I know I am wrong at something :))
- Connect ATX connector's pin 14 of first and second PSU together (that's power on signal).
- Do the same with pin 15 (ground) (do I need to connect ground together, and if I do should I connect all pins that say ground or just one ?).
- Somewhere I saw that I should also connect pins 8 together (that's power ok signal). Is this true ?
- Anything else ?
- What is best way to connect these wires (preferably without cutting them) ?
