Mintyttx Posted September 26, 2011 Posted September 26, 2011 Hey guys I'm gonna build my gaming computer and was wondering if a 750w will be enough for me. I do plan to overclocking my CPU quite high like 4.7 ghz or 4.6 ghz and the psu I choose is 90 % efficient and gold certified here are my specs. i5 2500k, Asus P8P67 Pro, WD Blue 1 TB, MSI GTX 580 twin Frozr II PE/ OC (I do plan to OC), Coolermaster elite 431 plus with side panel, G.Skill Ripjaws 1600 mghz 8 gigs, noctua nh-d14, seasonic x750, and 5 case fans. Am I missing anything? :s Do you think it'll be enough?? Or do I need a 850w ?? Ooo yeah and the PSU has a single 64 amp rail Share this post Link to post Share on other sites More sharing options...
Owenisbad Posted September 26, 2011 Posted September 26, 2011 Easily enough Share this post Link to post Share on other sites More sharing options...
wevsspot Posted September 26, 2011 Posted September 26, 2011 I agree with Owens. You should be good to go. If you ever decide to add another GTX 580 you'll need to be looking 850 - 950W though. Share this post Link to post Share on other sites More sharing options...
El_Capitan Posted September 26, 2011 Posted September 26, 2011 More than enough with overclocking headroom. Great choice on your PSU, btw. Share this post Link to post Share on other sites More sharing options...
Black64 Posted September 26, 2011 Posted September 26, 2011 If you plan on upgrades I would go for a 850. But a 750 is fine. Share this post Link to post Share on other sites More sharing options...

Was gonna get the 850w version so that I could sli in the future but apparently 850w isn't enough for sli 580's , so just went with a 750 Thanks for the reply btw Share this post Link to post Share on other sites More sharing options...
wevsspot Posted September 27, 2011 Posted September 27, 2011 You're welcome. Since you bought a quality power supply it may hold it's resale value fairly well. Maybe when you add that second GTX 580 you'll get lucky with a good resale price on the 750W and find a new 950W on sale Share this post Link to post Share on other sites More sharing options...
Compxpert Posted September 27, 2011 Posted September 27, 2011 I only run 700W in my main rig and thus far its been more than enough to run a single 6970 and a Core i7 920. Its never let me down so I can assure you 750W is enough. I see people getting these 1KW PSUs all the time and usually for their setups they are extreme overkill.

altec.gs Posted October 2, 2011 Posted October 2, 2011 More than enough. High quality (Thermaltake XF, Seasonic, XFX, Corsair,..) 650W is enough for any single gpu computer. Share this post Link to post Share on other sites More sharing options...
nickk47 Posted October 2, 2011 Posted October 2, 2011 ^Yeah. People just like to have the insurance and the comfort in knowing they can upgrade down the road, even if its mega overkill lol Share this post Link to post Share on other sites More sharing options...
