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

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.

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-gt...

Should be ok I guess.

That PSU is sufficient; you're good to go.

See no problems at all with that PSU should be good to go.

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.

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.
