Pentium D 940 Power?

Check the motherboard specs. 4 pin should be fine.

I recently bought a 620w power supply. It had two seperate 12v 4-pin square connectors. It was made so just one or both could be plugged in. This leads me to believe that 2 of the connecotrs would be suffecient.

I think this is a more motherboard specific question and not your CPU.

certain motherboards may need diffferent power connected for different pruposes. check with the manufacturer what it recommends

Would it do any damage to the system having this current 4-pin connector or the potential 2x 4-pin connector?

Please provide a motherboard manufacturer and model number. Thanks,

I built a system with each kind, so I'll explain.

The 8-pin power connector is on an EPS12V power supply. They generally break apart into two 4-pin segments but do not have to. The 8-pin connector is for use on Xeon boards, particularly dual- or quad-CPU setups. I built a dual-Xeon machine and it needed the 8-pin power supply in addition to the normal 24-pin ATX one.

ATX boards (which yours probably is as PD 940s are LGA775) take a 4-pin 12V power connector. If you have an EPS12V PSU, the 8-pin unit can be broken in half and one (and only one) of the 4-pin halves plugged into the motherboard with the 24-pin ATX connector. But a normal ATX12V PSU is fine for your chip, you do not need an EPS12V one.

My motherboard: Asus P5WD2 Premium

I did attempt a system boot up with the current configuration and although power went through to everything, I had nothing appear on the screen and no usual HDD noises like you do during a boot-up sequence.

I'm hoping this is purely a PSU issue and not anything else.

Any suggestions? What replacement PSU does anyone recommend?

actually, I just bought the 500W power supply listed in the link above. It only has one of the 12V connectors, not two. Like MU said, it seems like a EPS12V would be the one to purchase.
