PSU requirement for dual GTX 1080

joepham14 · Nov 30, 2016

I have a 600W PSU and wondering if its enough to run 2x Asus GTX 1080 Turbo?

No you will need to buy a new psu that's at least 750 watts.

It'll really depend on the rest of your setup and the quality of your PSU. A Skylake CPU (~100W) + 2x 1080 turbos (360W) and the balance of your rig (call it 100W) is right on the cusp of a 600W PSU. If it's a quality 600W PSU, it should work, but wouldn't be recommended.

600W, even from a quality PSU is likely a little low though.
I assume, considering you only mention "600W PSU" that it's probably not the best quality.

You want headroom over and above system requirements, skimping on the PSU can cause component failure

Definitely not enough. That PSU is 'ok', but not great, certainly not for dual 1080s!

joepham14 · Dec 1, 2016

so 750W is enough i assume

Yes a 750 will suffice - get a good one with at least 50 or better AMPs on the 12 volt rail
