Power supply for gaming rig

zeshan_1 · Sep 30, 2015

This my rig that im planing to buy:
Corsair obsidian 450D
Intel 4690k
cooler master 212 evo
Maximus VII hero
G skill trident x pc3 19200
1tb wd hard disk
ssd 120 or 320
Msi gtx 970

So im little confused about power supply. Im thinking of buy evga superNova G2 because i heard it is a very good power supply. So my question is how many watts do i need for this rig. Also if you think that something should be replaced for better performance in gaming, let me know...THANKS

The build you made seems pretty good . Yes, the supernova G2 is a good power supply unit. The GTX 970 draws 145 W and it need a minimum 500 wattage psu. A G2 550W will be enough to run a single 970 and a single 980 too.

If i get a 850w power supply, is it overkill for my rig because im building a pc that last long...THANKS...

zeshan_1 :

Yes, it's overkill. Even 500w is quite alot for this build. You could easily run 970s in SLI with just 700-750w.

So should i go with evga supernove g2 750w?

ben001 · Sep 30, 2015

For now, yes but it will help if you pair 970's or 980's in future.

zeshan_1 · Sep 30, 2015

Thats because maybe i upgrade my rig in future

zeshan_1 :

If you want to add a second 970 in the future, then yes, the G2 750w is a great choice.

zeshan_1 · Sep 30, 2015

Thanks for the help guys.

ben001 · Sep 30, 2015

There is minimal chance that a card will draw more than 375 Watt where 700W will be the minimum system power requirement. That 850w will help you a lot even if you overclock.

ben001 :

OCd 970s only uses 243w under torture

So there is absolutely no way that the card will ever use 375 watts.
In normal gaming it doesnt even need 200w under full load.

zeshan_1 · Sep 30, 2015

So 750w will be more then enough

migronesien :

A misunderstanding, I never said about 970/ 970's, Titan Z is the only card which draws 375 W which is quit higher than others (right now in the market) . So, in future there is a minimal chance that a card will draw more than 375 W. That's what i told. He will need that 850 watt if he add some further upgrades including overclocking cpu/gpu.
He asked, getting 850w power supply unit is worthy for further upgrades in future, the answer is already in this post. For now, 750w is enough.

Sorry to ask sir but its really hard to find evga power supply here(pakistan). They say thermaltake is available. Can you recommend me thermaltake power supply in case if i cant find evga...THANKS...

Try this one : http://www.thermaltake.com/Power_Supply/Toughpower_Series_/Toughpower_Grand/C_00002569/Toughpower_Grand_750W_Platinum_Fully_Modular_/design.htm

zeshan_1 · Oct 2, 2015

Some people say stay away from thermaltake power supply(i dont know why). What do you say about it...THANKS for replying...

ben001 · Oct 2, 2015

And i'll say, try to stay away from those peoples. Read this link very well : http://www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html
