I have a PNY GTX 770 and it really does not have the same power delivery as other vendors. Like I am pretty sure the Asus direct CUII PCB works better for overclocking. So does the PNY take less power from the PSU..?? All the 770's pretty much have the same TDP and PSU requirements. I think at is around 230w TDP maybe less. I have an AX760, would this be optimal for 2 PNY gtx 770's?
