Power Supply Watt Needs for an I7 4770k + GTX 780

post #1 of 6
Thread Starter 
I'm about to build my new system and I know this has been probaly done to death but after reading many topics about this subject I'm not quite sure what to get.

i7 4770K ( overclocked )
Nvidia GTX 780 3GB ( overclocked )
Corsair H60 Cooling
3 Sticks of RAM
1 WD 1TB harddrive
1 Samsung SSD
1 Optical Drive

- I will not upgrade to SLI later on.
- Probaly not buying anything else after this build is done.

Currently I don't know if I should go for a 750watt Corsair TX or will a 650 watt PSU be more then enough for my needs? ( nvidia itselfs says 600 min for a GTX 780 )

While were on the subject, Corsair TX series or the XFX black series? Many people seem to say that the XFX black edition is the superior power supply.

Hopefully someone who knows allot more about PSU's then me can advice me about this subject.

Thank you.

No 750 watts is way overkill you dont need more then 550 watts buying more is a waste of money

The Cosair TX is made by CWT the XFX units are made by Seasonic

Thank you.

That setup would consume less than 450w at 100% load for both CPU+GPU (& that's rare unless folding....etc).

Depending on where you live, choose one from this list that's on sale in your country. Don't limit yourself to just Corsair. 500w range should be more than enough.
Proper PSU Reviews.


Here's how to put your rig in your sig:

Thanks for your replies. I've been out of the game for a long time and figured you'd need allot of watt to power a beast like the 780 GTX. Would you guys suggest a Corsair AX ( i've always have Corsair way up there in terms of quality ) or will a Seasonic or XFX be the the better choice? I know there are different models for all brands but willing to spend about 120 euro / 160 dollars and not 200+ euro like some of the real high end models. What would you guys recommend for about 120 euros/160 dollars?

Corsonic is overblown and overpriced you got so many just as good or better options

If you are from the US pretty much the best bang for buck PSU is the Rosewill Capstone
