Hi, I'm in the market for a new PSU, it should be able to handle 780 and an i7. What PSUs do you guys recommend? (PS, I had already posted a thread, no one replied lol...here it goes again:nerd Thanks!
I'd go with a quality 750W like a HX750 from corsair. You really only need 600-650W, but you will want to overclock and some overhead never hurts.
For single GTX 780 even high quality 450W PSU would be enough even with some overclocking. 750W is ridiculous overkill for single GTX 780. Price wise 550-600W PSU's make most sense and those would be enough even if you overclock the crap out of you system.
My 780 can pull 315W at 1.212V by itself. A 450W is not enouph. I said a 650 would be enouph but suggested some overhead. An overclocked i7 pulls around 150W an overclocked 780 350W that's already at 465W power draw without drives RAM or case fans. BTW Nvidia suggest a 600W minimum on a 780. You don't want your PSU running at maximum output 24/7.
Thanks for the suggestions, I'd like to keep it higher as well so that I can SLI in future (doubt 750W would do it) or maybe use it in another build. Now, the question is which one do you recommend? Like Corsair, SeaSonic, Cooler Master, etc. There are so many to chose from, many models from each manufacturer..
What part of the world are you in? Generally anything from the likes of Seasonic, Superflower, XFX (Which are rebranded Seasonic units), and so forth should be fine. I'd aim for at least a gold rated unit, 850w + if you intend to run 780 SLI in the future.
Thanks, I was looking at Corsair HX 750 and 850, are there better models from other brands that I must look at?
If you are serious about SLI 780's then 850 is the bear minimum you should be looking around a the 1000W units. Corsair, Seasonic, XFX, EVGA or PC Power and Cooling would do look for one with 80+ gold or better.
Well no overclocking 850W can work. Average user land overclocking 1000W is adequate. Your level of overclocking yes more than 1Kw is needed.
Any 600w Silverstone or Seasonic is what i would Recommend. Currently running a I7 2700k 4.5 1.32v GTX 780 1.2v i believe and 1280 core and about 1600+ on memory i think maybe more and its stable with my TT 550w Smart Power. If you want to go SLI Silverstone Antec or Seasonic 800-850w would do nicely.Avoid corsair unless its a AX-AXI-RM most are garbage from my own experience.
Really looks at both of my current PSU's (one is 6 years old not a problem (TX850) the other is 2years old same (HX850)) The lower end Corsairs may have problems but anything above TX would be fine.
