Is Corsair VS650 PSU Enough to Overclock MSI GTX 780?

Hi everyone. I nearly completed my build. Here is what i bought.

i5 4590 cpu
MSI Z97 Gaming 3 Motherboard
Gskill RipjawsX 8GB(2x4GB) 1600Mhz CL9 Dual Kit Ram
250GB Samsung Evo SSD
Corsair 300WR windowed case
Corsair VS650 650W power supply
Cooler Master Hyper 212 Evo cpu cooler

I won't overclock cpu so i didn't get a K one. I will only overclock gpu. I want to buy MSI Gaming GTX780 Twin Frozr.

I found this website. It says GTX780 requires 575W psu, but doesn't say anything about overclocking.

My Corsair VS650 psu is 650W but is gives 600W from 12V. Will 600W be enough to overclock GTX780 and is it enough for system to work stable?
Thanks for your help.

  1. With a locked i5 and 780, you're looking at running around 375-400w MAX at peak load. 650w is plenty of power, though the VS series is their lowest-quality model. If you're overclocking on air, you should be alright, though a better power supply (better quality, not more watts) would be recommended.

    Thanks for the answer. I will use air cooling like you said. Forgot to write it. Edited my first message now.
    I will use Cooler Master Hyper 212 Evo cpu cooler. I was gonna buy Corsair CX600. It gives 552W from 12V.
    Corsair VS650 was on sale for a very good price so i bought it. Psu's are expensive in Turkey so i can afford only VS650 and CX600.

    A GeForce GTX 780 needs 42 amps on the 12vrail and a 600 watt power supply.

    The VS650 has 50 amps on the 12v rail and is sufficient to run your specs , with a GTX780
    :D

    Thanks for the answer. I was using laptop for 7 years. This will be my first build so i don't have a lot of experience about hardwares.
    So VS650 is enough to run GTX780 but will it also be enough when i overclock GTX780? Does overclocking increases power need?
  6. No overclocking with that PSU it has poor capacitors , it will run it but NO overclocking.

    I saw on a local forum that people are overclocking Sapphire R9 280X, GTX770 and some lower models with VS650. So i wondered if it will be enough to overclock GTX 780. As far as i know, AMD gpu's are power hungry. A lot of people use VS650 and people suggest VS650 for builds here. I think i won't oc for 1-1.5 years.Then i might try to overclock with VS650 or i can get a better psu if i have enough budget in time.:wahoo:
  8. Good idea , don't risk it , wait till you can get a better supply.
