Hi people,i have a question,I got a Powercooler 500wts with 2 pci-e connectors but its a single wire so i dont know if they got enough power (2 pci-e 75wts EACH its what XFX.com says.Now,could i connect only one PCI-e connector of the PSU and the second one with the PCI-E TO 2 MOLEX connectors?.What dou you think ?

EDIT: I GOT a E7500,4gb RAM ddr3 1066ghz,1hdd WD 750gb,2 80mm with led fans and a TT turbofan 120mm.
