Will this card work with this power supply?

Hey, I have a question regarding how much power a GTX 770 Lightning Edition MSI card will take up.

Currently this is my setup:

i5 3570k 3.40Ghz
8gb DDR3 1600mhz
1tb HDD
Z77 Motherboard
A DVD drive

and an Evga GTX 660 Ti 2gb (NO SC, NO OC)
with a 650 watt power supply.

Will a GTX 770 Lightning work with everything listed (excluding the GTX 660 ti of course) with a 650 watt power supply?

Thanks, Jake.

  1. Hi. It depends on the PSU you have. If it is a Corsair, there should be enough on the rails for some headroom, and possibly with a Seasonic. The wattage is fine as long as you don't go sli.
  2. Tell us which 650W supply you have.

  3. If you have something like a SeaSonic 650W it should work.

    Its a blank with no logos and green. I believe its an Antec not too shure though
  6. If you are not sure..... how can we be sure. You need to take a closer look at your psu. Some psus rated at 650W are not worth the box they came in. If this is your supply it will be fine.

  7. If it is the one that dish_moose linked to, it should be fine. With the cards these days, You need to make sure you have enough on the +12v rail. That PSU that was linked to had 38a, so should be fine. With the newer cards, I prefer having some 40a+ on the rail. I am known for having PSU overkill on my builds, but if I should go sli / crossfire I'll be fine.
  8. 38A on each rail - 2 rails.

    Yes it is the one Dish_Moose linked, it should run it no problem?

    I don't see any problem with a single card. You would have to upgrade should you want to go sli or Cross fire though.
