Extra MB Power Port

post #1 of 7
Thread Starter 
I have a molex power port on my motherboard, the Extreme 6, which is right above my GPU's. I just bought another card for SLI but it has not yet arrived yet. Will I need to use that port when it comes in?

Motherboard Molex power injector ports (that's what I call 'em anyway) are there to provide additional power to devices that are plugged into the motherboard's expansion slots. Certain RAID cards and other devices require more than the slots can put out but are not quite hungry enough to require the use of a 6-pin connector.

It's always a good idea to plug it into your PSU. It'll only use the power that it needs and is never a problem to do so on a properly made board with good power.

So even with one GPU installed, I can plug it in now?

It's been my experience that if your motherboard has a 8-pin EPS +12V ATX connector, and your PSU has a 8-pin EPS cable, you won't need to use that Molex 4-pin port. If, however, you only have a PSU with a 4-pin ATX supplemental power cable, you might need the Molex in addition to it.

I would definitely plug it in. I lost 2 EVGA boards that literally fused the 24 pin connector to the board due to it not having auxiliary power connectors. A year later they came out with the "power booster" add on that solved a problem that didn't exist according to them frown.gif So after loosing almost $1k in hardware I always plug in whatever is available to boost power and avoid EVGA at all costs.

Wow, I do not know anyone else speaking negatively about EVGA here. Interesting though...

EVGA GPU's are generally very well made and their RMA service is absolutely second to none. Their motherboards, however, leave a lot to be desired. I had one blow the heck up on me a couple months back. MOSFET's blew when I wasn't pushing it too hard.

So, yeah, their GPU's are great but I wouldn't touch one of their motherboards with a 29 1/2 foot pole.
