Is 600w enough?

[ScottytooHotty]

Hi All,

I am looking to get a second 780 for my rig but am not sure if I need to upgrade my PSU as well. Any help appreciated.

I have:

Corsair 2013 Series GS 600W PSU
Asus P8Z77-V LX2 Intel Z77
i5 3570k overclocked to 4.5ghz
gigabyte GTX780 windforce
TeamGroup Elite 16GB (2x8GB) DDR3 PC3-12800C11 1600MHz Dual
Alpenfohn K2 Mount Doom CPU Cooler
Samsung 840 Series 120GB SSD
Seagate 1TB HDD
Soundblaster X-fi extreme audio soundcard

I've read 650W is kind of the minimum power for SLI 780s, but I wouldn't even try it using 650W myself, especially if you're into your overclocking. If you can afford SLI 780s you should invest into a bit of a better PSU too I'd say. 750W should be fine, personally I'd get something around 850W and it will power everything you need for a long while within reason.

Second slot is only x4 so your MB doesn't support SLI and no it wouldn't have been enough.

Good point, the website specs say it only supports CrossfireX.

I had already planned to get a better mobo anyway just wanted to know whether i had to upgrade my psu as well, AX760i it is then

If you are going for a new motherboard option, you may aswell go Haswell

The AX unit will be great and will do what you want, I was going to suggest RM850 which ill allow for sli later aswell.....

I ran a 650 watt PSU with overclocked 780's, A 4770K overclocked to 4.60GHZ, 32GB 2400MHZ memory, Mobo, 1 x SSD, 1 x HDD, Air CPU cooler with 2 x fans, 2 x case fans, Sound card, Network card and a lastly, A DVD burner.
I did switch out to a 850w in the end though just to be on the safe side.
