Solved

I am getting an MSI GTX 770 Lightning Edition and i need to know if my 600w PSU can hold it up.

as stated above, can my PSU take on the 770?
I have :
GIGABYTE GA-Z77X-UD3H
1 1.5 TB HDD
Intel i-7 2600k @ 3.4Ghz
5 Fans (2 120mm LED Lights and 2 120mm normal and 1 140mm normal)
8 GB RAM (2x4 @ 1333)
1 CD Drive

Can the 600w PSU handle the GTX770 with these things?
So far i have been holding up a Radeon 7850 2GB with that mentioned above. and all with a 600w PSU

  1. What is the make/model of the PSU? This will make all the difference.

    Since you're running a 7850 on this supply already, I'd tend to think you're ok running the 770 on the same supply.
  2. Yeah, it really depends on the PSU. If it is a good one, then yes. If it's a CM, Logisys, Apevia, Diablotek, or other cheap brand then no.

    The requirements from nvidia are 600W, check here : http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-770/specifications

    Should be ok I guess.
  5. That PSU is sufficient; you're good to go.
  6. See no problems at all with that PSU should be good to go.
  7. You're good.
  8. Thanks guys, appreciate your time and answers!
  9. Just be aware that 600 Watts is the minimum recommended by Nvidia for a reference model GTX 770. If you plan to use the MSI Lightning in the way that it was intended, extreme overclocking, then you might run into a limit. The Lightning uses 2 8-pin cables to draw more power for overclocking, as opposed to the reference 6 + 8-pin power cables.

    I still think you're going to be okay. Why? You have a high quality PSU, and the fact that the experts at Guru3d only recommend a 550 Watt PSU on a highly overclocked GTX 770, the Inno3D Herculez:

    This.

    However if you plan to overclock the CPU and the GPU, get a decent single-rail 650W PSU (minimum) or 850/900W if you plan to SLI later.
  11. Graphics card manufacturers overstate PSU requirements in the attempt (often futile) to account for all the liar-labeled PSU-shaped objects out there. If you go through recent SBM cycles where they measure power consumption, they are always a LOT less than the "requirements" imply they should be.

    I agree. The requirements account for the situation where someone picks up a 600W bargain-bin PSU designed in 1997 with 175W of its 600W concentrated on the +5V or +3.3V rail.
