Corsair 520W question...

I'm just finished up my new rig, however, I have noticed that one of the main power leads coming from the PSU, is an 8-pin and I can't seem to find anywhere to put it. I'm presuming this is because there IS nowhere to put it but in anycase, what is it's use anyway?

Thanks!

some motherboards now use an 8pin cpu socket instead of a 4 pin (iirc)

Yeah thats right

Ah right, is that dependant on the chipset or the manufacturer?

Is it not an 8 pin PCI-E cable?

Not on that particular PSU. Coming from the main cables that aren't detachable is a 20/24 pin ATX, a 4 pin cable, and an 8 pin cable. The modular ones that you can put in which are the PCI-E are detachable and 6/8 pin.

Why was the EPS12V form factor created?

The EPS12V form factor is designed for server class motherboards that require more power. EPS12V is usually found on power supplies that are 460 Watts or greater.

My power supply is an EPS12V but my motherboard has an ATX12V connector, what do I do?

The EPS12V connector is designed to be backwards compatible with the ATX12V connector. However, due to limited space on the motherboard, motherboard designers placed capacitors next the ATX12V power connector. These capacitors will obstruct the EPS12V connector and you will need to purchase an EPS12V to ATX12V conversion cable kit. The EPS12V connector is shaped to fit the ATX12V in one way only. If the EPS12V connector does not come in contact with any other motherboard components when connecting to the ATX12V, then it will work fine without any sort of conversion cables.
