Why does this PSU not have any PCI-E power connectors!!. I need one but this PSU seems to have none. The model is the 450x.

Thanks in advanced fro your answers

It's an old design for older computers. The key to that is the relatively heavy 40 amp 5 volt rail and the really light 16 amp 12 volt rail. 16 amps is not enough to power a medium powered CPU and graphics card.

Compare the specs with a 400 watt 400CX Corsair with its 30 amp 12 volt rail.

It seems to run my q6600 and GTS 250 fine though???

You have very little reserve capacity left. A stock Q6600 pulls about 7.5 amps @ 12 volts with all four cores loaded to 100%. OC'd to 3.6 GHz, it pulls 9.5 amps. (I have a Q6600 and I measured it with a lab calibrated clamp-on DC ammeter.)

A GTS250 pulls about 8.5 @ 12 volts amps under a heavy 3D load.

You apparently haven't loaded your system heavily enough. Your first sign of trouble will be apparently random reset and reboots under heavy graphics loads.

I agree, you need a quality PSU. Just because it runs your rig now doesn't mean it won't fry the whole thing tomorrow.

I know codegen, i classify them as "no name" brand. They may work fine for light PCs, but i wouldn't use it to supply power to a system i'm proud on or consider to be of importance.
