Which i thought would do the job. My problem is the power supply only has 3 molex connectors and no six pin PCI-e connectors (my fault i admit) so i have to use all the molex's for this. But when i turn on the comp the fan on the graphics card doesn't spin and the monitor doesn't turn on.
Its rated higher than it likely should be, it isnt one of the better brands. Corsair is a good brand and is sufficient instead of overkill for the card. The fact that that power supply is cheap but rated significantly higher does not indicate quality parts. Remember if a PSU goes it can nuke your whole system.
The Hiper has the same connections as the OCZ one I linked but the OCZ offers one more rail (and more amps) plus is a better manufacturer (parent company of PC Power and Cooling).
