Is this power supply overkill? (New to building PC'S)

Davcoll · Jul 3, 2014

Hi, this is my second post on these forums. I was wondering if this power supply is overkill (or under.) for my current project. Anyway, the PSU -http://www.newegg.com/Product/Product.aspx?Item=N82E16817139010

And my build:

RAM - http://www.newegg.com/Product/Product.aspx?Item=N82E16820145345

GPU - http://www.newegg.com/Product/Product.aspx?Item=N82E16814130918

CPU - http://www.newegg.com/Product/Product.aspx?Item=N82E16819116501&cm_re=i7_3770k-_-19-116-501-_-Product

no its not overkill to the max ,
your gpu needs a 600w psu , you could go for lower wattage but 150watts will give you lots of headroom and that is a great selection for a quality psu

edit this will do the job just aswell and save you some money

Davcoll :

Hi - As already mentioned, the 750 will do no harm, however a good 650 is more than enough for that system,
and there are several PSU's avail for a sys with a gtx780 for far less $$.

Also, do you have the rest of the parts already? If not, you can get Haswell generation CPU & MOBO for about the same $$ as your spending on last gen (Ivy Bridge). I've been checking Ivy bridge pricing recently (possibly to upgrade) and haven't found anyone bailing on them at cheap prices. If I do upgrade, I'll be goin Haswell, more deals happening.

GTX 780 - System Wattage with GPU in FULL Stress = 340W/29 Amps - an average system requires 550W PSU.

For the single GTX 780 a quality 650W is ample, that way you would give yourself plenty of headroom. You could run 2x 780's on a quality 750W like the one listed, if you aren't overclocking seriously/extremely or using more powerful 780 varients.

Better, cheaper alternative to the HX 750
