Hi, this is my build:
Everything is new, exept for the PSU, which is from my current PC and I wanna know if I can still use or if I need to upgrade. This PSU has been running a Core 2 Quad Q6600 and a GTX260 for quite a while now, if it serves as reference.
The PSU has two 12V rails, each with 18A max. It has 2x 6-pin power PCI-e connectors and 4 molex connectors that I'm not using. The GPU needs 2x 8-pin power PCI-e connectors and came with 2x 2molex-to-8pin adapters, but I guess I could buy other adapters if that might solve the problem (note that curiously the molex-to-pci power adapters have only 6 wires and the other 2 don't even have a pin in the pci power conector. This would suggest that either 8-pin is not necessary or that Gigabyte is really cheap with the adapters they through inside the box).
According to EVGA (couldn't find anything on Gigabyte or nVidia), the recommended system specs are 42A on the 12V rails and 600W. I guess this are general recommendations, but maybe not entirely necessary. I mean, the cpu is relatively non power hungry (certainly less than my current CPU) and my main disc is an SSD, though I do have 2 Sata HDDs, I've no idea how much power they need. The GPU takes 230W, then I = P/V=230W/12V = 19A. My guess is, if I were able to feed the gpu with both rails, then I have 17A for the rest of the system. If I can't, I know I'm toast.
The thing is, how do I know which rail is which? I should expect that each of the PCI-e connectors from the PSU carry a separate rail, but I can't use them since they are 6-pin. I could use the molex to 8 pin but they are also 6 pin really. Wouldn't this put at risk the amp rating of the wires? (I mean, I guess that's the reason why they keep throwing in more pins).
Anyway, is this PSU enough to run the PC? And is there anyway to hook this up without maxing out the 12V rail amp rating or the wires/connectors amp rating?
Thanks in advace!
