yes but just enough juice without any OC on the GPUs

Budget? Uses? Currency? Location? Operating System? Peripherals? Monitor? Use PCPartPicker wherever possible.

It should be ok, considering the actual power draw from the wall will be a bit over 600W

both GPUs 500 watts at stock

 

with a mild OC you will be seeing 550 to 600 watts

 

your CPU eats 85+ watts and the rest maybe 50 watts

 

so year the 750 will be the bare minimum

850W is the suggested wattage

 

but if you are going for more OC with custom BIOS hack and overvolting

 

then you can look at 1K watts PSUs

I could even get a 1000w psu! I was just curious if I could run them with 750w till Christmas? I wouldn't oc just to be safe

If I had to I could just pull the second card and wait till I get a bigger psu... It'd only be a month or 2 months.

It'll power it without OC but I wouldn't run the OCing into the ground.
