I just bought a Zotac GTX 560 Ti on eBay. My motherboard is a GA Z77X UDH3H (http://www.newegg.com/Product/Product.aspx?Item=13-128-...).

#1 First of all, since the 560 comes with two PCI power cables, do I have to plug in both of them into the card?

#2 I am not quite sure why there is two molex connectors on the six-pin power adapters? Do I have to plug in BOTH molexes to my PSU, or do I only need to plug in one molex on each of them?

#3 Does it matter where I plug the molex power adapters into? Is it possible to draw too much current out of a single molex wire coming from the PSU?



If I need to give more explanation to any of my questions, please let me know.

What is your power supply? I would recommend against adapting molex connectors into PCIe whenever possible. For the card, yes you have to plug power into both ports on the card. If the connectors are seated properly, the correct amount of power will be drawn from the PSU.

My power supply is a Thermaltake 750W Bronze Certified (modular) Also, since you say "I would recommend against adapting molex connectors into PCIe", do you mean I should just use a 6 pin connector directly from my PSU?

In that case, you shouldn't need to use the molex adapters at all. There should be a 6x6+2 pin PCIe connector on that power supply which will work fine to power the card. Unless that power supply is really, really old?

So just plug in two 6 pin PC1 cords into my PSU, then plug those into my GPU?

Sweet! Definitely clears up a lot of questions for me. One more thing: could I just use one of these cords and plug both in at once: http://www.microcenter.com/product/318756/PCI_Express_6...(62-pin)_Adapter_?gclid=CIDhyaXDobgCFQtgMgodoyYASw ?

I guess you could, but if your PSU is modular and you can attach two 6 pin PCIe cables to it, it's better to do that and avoid using adapters. Your PSU or cables might react strangely or become damaged if the amount of power being drawn through one cable is twice what it normally would be.

My guess is the OP lost the modular plugs.

Ok will do! Thanks once more for all your help! I guess I am considered a n00b in Graphics Cards, LOL.

Thanks!
