If doesn't have a few pcie lines (vga power cables on the psu), it looks like your psu may not be up to the task of power a powerful gpu. Try to find the sticker on there for the make and model.
If possible, what's your budget to get a new psu? Even a budget-entry, but good psu, will have at least two sets of vga/pcie lines for a couple of gpu(s) at 750w.
edit: btw, even if its rated at a high wattage, a pos psu can deliver a lot less and will have a tendency to blow up and possibly kill your components. i've been lucky twice (noob days) and came out with no dead components but two very dead pos power supplies.Edited by wermad - 6/12/13 at 3:20pm
