GPU adapters wattage

[Js4days1]

I just bought a gtx 770 windforce edition not knowing it required two 8 pin connecters even so I thought I would be ok seeing as my power supply has 4 extra 6 pin connecters but the GPU only came with 2 molex to 8 pin adapters. So my question is, are these adapters going to allow my 770 to run at its max?

What power supply do you have? Running off the molex cables is usually the last option IMO. You could always grab some of these converters (assuming your PSU is good enough to handle the 770): https://shop.pcpower.com/accessories/6-to-8-pin-adapter.html

Since your PSU has a bunch of 6-pin cables, you should try using a pair of those before trying to use the 4-pin Molex adapters - the PCIE power cables have three 12V wires and pins coming from the PSU, which should provide much lower wiring losses than using the Molex connector which only has one pin and wire.

You may need to use a "cheater" adapter if the GPU's design insists on having at least one 8-pin PCIE power cable. Many mid-range cards with dual 8-pin connectors or 8+6 are actually ok with 2x 6-pins or 1x 8-pins.
