What PSU should Ill get? I think between 650W-750W?

If any part is missing just tell me and I will list it.

Preferred PSU company: Seasonic
Preferred Series: Series X

Thanks for the help.

Preferred PSU company: EVGA
Preferred Series: SuperNOVA G2
select. 650w, click, add to cart

 

[Gnuffi]

also would strongly recommend an ssd atleast for OS
if you dont like the awesome Evga PSU, seasonic does have an X series 650w

 

[Inkiad]

Seasonic X-750 can run dual 980TI.
If you have budget for a X-650, go for it. 7 years of warranty, all japanese capacitor, full modular. Also you can draw 648 watt in the 650W psu. Very good psu.
But if you find the EVGA 650 G2 for same or less money than the X-650, go for it. One of the best psu on market right now with 10 years of warranty. Can't go wrong with G2.

The Seasonic X760 is a good choice. Which country are you from?

Israel.
Does 650w isn't enough for my specs?

 

[Gnuffi]

yes 650 is more than enough for your current specs even with overclock CPU and gpu
but 650 wont run SLI, so if you plan to do SLI one day, you need a bigger PSU

 

[HydroBull3T]

Gnuffi, I don't like doing sli nor crossfire due bad experience in the past, I'm plannig to overclock only the cpu i5 2500k to 4.3ghz.
And in few month upgrade the cpu and motherboard.

In this case the 650w is still enough?

 

[Gnuffi]

yes tier 1 psu will do that fine, both evga supernova g2 and seasonic x series are tier 1, "stronk" psu's will serve you good for overclocks, and any GTX single card, TI or Titan, even AMD power hungry card if you want one day

 

[Inkiad]

650W is more than enough. You will draw close to 300 watt.

 

[HydroBull3T]

Thanks gnuffi, inkiad, how did you calculated it?, I did some calculation and acheived the 542W result of my system..

 

[Inkiad]

i5 2500K - 95W
GTX 970 - 145W
3 drives - 60 W (20W for each, approximate. can be less.)
Each fan draws close to 2W
Close to 300W. Max will be about 350W. However load you put.

EDIT: Sorry, did not see you have two DVD drives. Still well under 350W. Max will never exceed 400W, even if you play games, use all HDD and DVD drives.

 

[HydroBull3T]

Inkiad, strange, psu calculations sites marking 480W-595W.. 0-0

 

[Gnuffi]

and these are peak loads, which you wont be at 75% of teh time, peak load at 90% is fine for PSU
your peak load is now 60% your average load even less, 650w equal perfect for your build, even with OC

 

[Gnuffi]

PSU calculations sites factor others stuff in, and dont forget, some of them sites want to sell you a PSU so they "fluff" the numbers up a bit sometimes to sell you bigger PSU

and remember these are tier 1 PSU chosen, so dont worry

 

[Inkiad]

Calculators assume max power draw from HDD's and DVD drives. Which is if my memory serves 30W each.
Just checked seagate website, their hdd's draw average 9W of power. Check here - http://www.seagate.com/as/en/internal-hard-drives/desktop-hard-drives/desktop-hdd/#specs

 

[HydroBull3T]

Thanks inkiad, I think ill got than with seasonic x-series x650 650w psu as I also will upgrade the mobo and cpu in few months.

Right gnuffi?

 

[Gnuffi]

Yes Seasonic x650 is top notch!
no need to upgrade PSU for many years unless you want SLI one day, so is good choice for the build you plan now

 

[Inkiad]

Go with it, one of the best psu right now. But if you can find EVGA G2 for less money, that will also be a good option. X series and evga G2 series are kinda similar in performance.

 

[Gnuffi]

Evga SuperNOVA G2 has 3 more years Warranty than Seasonic, tho, could be worth considering
(even tho in 7 -10 years you prob already on 3rd build with 3x GPUS and 1200watts anyway 😉)

 

[HydroBull3T]

Unfortunately I can't find an evga psu anywhere in my country expect 1200W, so ill stick with seasonic. Thax!!
