Quick question (molex on mobo?)

Mark A · 30 Jun 2007 at 22:28

Hi,

I'm building a PC for my dad using a Foxconn NF4SK8AA motherboard and a single 7600GT gfx card. Ive just noticed theres a molex on the mobo above the gfx card slot. Ive never come across this before when i built my 2 previous rigs and I'm not sure what its for. Is it for if your running SLI?. Will i need to plug a molex into it if I'm only using a single card?.

TIA

Mark

May be extra volts for cards or for memory/cpu, you best to look at manual or if not got one, download as .pdf, normally these sockets are special shaped not molex but I have seen GPU's with molex even though they were newer PCI-E cards and it was not for fan as cards were passive where as PCI-E should have been enough to feed card power as its higher than AGP.

Thanks for the reply, ive got a manual and it says:

"AUX PEX PWR Connector: PWR2
This connector is auxiliary power which mainly supplies 12v and 5v power for the motherboard."

This is a pic of it.

I belive it is used for when you are running SLI...

plug it in.

it wont hurt, it can only improve stability

The PCI-E slot can provide upto 75w. thats a lot to ask from the ATX connector, on top of powering ram and all other mobo devices. so some boards have a molex todo this job.

It's to provide extra power to the PCIe slot for graphics cards that don't have built-in power connectors. Exactly like the 7600GT, in fact.
