Psu enought for system and what im looking for?

PachiiAxe · Sep 6, 2014

I really want to know if this PSU is good for an i5 4690k, Gigabyte Z97X Gaming 5, and ASUS GTX 780 DCUII OC?

EVGA SUPERNOVA B2 750W

I want to OC both gpu and cpu... GPU TO 1.0GHZ and Cpu to 4.0Ghz.. Is it posibble?

Thanks...

The only thing i want to do is to game and record with shadowplay...

It'll be enough for one card but DEFINITELY not for SLI. You'll need at least 850-900 watts for 2-way SLI.

The overclock WILL go successfully for both chip/card, unless you get a bad one.

EVGA SuperNova B2 750W is fine for a GTX 780 SLI build with a i5 4590k.
The psu you chose is enough.

SLI? SHOULD I WAIT FOR 980 OR JUST GO FOR 780?

PachiiAxe · Sep 6, 2014

IS IT ENOUGHT? 750W FOR 2 GTX 780s?

PachiiAxe :

No, it's not. Anyways, if it was, you'd have less efficiency because the more load you put on the PSU, the less efficient it gets.

PachiiAxe :

Ultimately, it is your choice if you want to wait for the GTX 980 or go for a GTX 780 now.

And yes it is enough for a good quality 750W psu for a GTX 780 SLI build.
Efficiency is sufficient enough with the EVGA 750W B2. If you want to spend a bit more, get the EVGA SuperNova 750W G2 or 850W variants..

Do you have proof the 780 only requires 750 watts?

Great deal on a 850w made by Super Flower.

But is the 850w version good for OC cpu and 2 WAY SLI GTX 780s?

Dark Lord of Tech · Sep 6, 2014

If your going to do serious overclocking , go to 1000w, if just overclocking mildly 850w will be fine.
