I've just bought a nice new PSU as my old one was giving out a nasty whistle.

When it came to wiring it all up again I noticed something weird. The CPU power on the motherboard only had 1 4pin connector inserted into the 8pin slot. Why would I have done that in the past?!

Should I now put another 4pin in?

I think I'm going to be on the lookout for a new Socket 1366 motherboard soon anyway as I want to be able to accommodate 2 graphics cards but only two slots on this are just too close together. Ugh.

using a 4 pin means your motherboard gets less power for the CPU. I would read your mobos manual and see what it says about this.

the power supplied by a 4pin is, on paper, enough to run a stock 920 (130W) . see this thread:http://www.tomshardware.com/answers/id-1631485/motherboard-pin-eps-pin-eps-connector-power.html

but if you psu comes with the right cable, why not use it? most likely your previous psu didn't have the 8 pin.

It's working, and appears to have been working for a while, with just a 4 pin. What am I losing out on by not having an 8 pin in? I'm not noticing any system instability.

I'm not saying that you're wrong, I agree with you - I'm just wondering what difference it makes.
