PSU for GTX 770

[novaldysama]

Hi guys, I have GTX 770 2GB MSI Twin Frozr, core i3 2120 and 4GB DDR3 RAM (upgrade to 8GB 4x2 soon).
So is 600w PSU enough to run gtx 770? And please recommend me best and cheap PSU for my computer.

Thanks.

Maybe. According to Nvidia the minimum power for a system with an i7 is 600watts. MSI also recommends a minimum of 600W With at least 42amps on the 12v rail.

If you already have the PSU, take a look at the label on the side and it should tell you how much continuous power each of the major rails can produce, both in watts and amperes. It is the amps that become important.
Additionally, the PSU needs at least one 6 pin and one 8 pin (or a 6+2pin) PCIe power connectors. It is not advisable to use adapters to obtain this configuration.
If you have not yet purchased a PSU, take a look at this article:

I recommend a unit from Tier 1 or 2; but if finances entirely dictate your choice the a Tier 3 would have to do.
DO NOT go cheap with the PSU!!! It powers everything and is the life-blood of the PC. Less expensive PSU's have less protection circuits (a couple I have disassembled had None) and generally use lower grade parts. If such a PSU dies it can kill other parts at the same time.
Either of these two would be a good choice:
