Hey all,

I'm one paycheck out from getting together my new build and the entire thing is running me around $2,000, give or take. At this point I'm simply doing some penny pinching and I am having trouble coming to a conclusion about my power supply needs.

My build will start with a single GTX 770, but I have plans to expand to an SLI configuration when I get enough for the second card and want to pre-emptively prepare by purchasing a power supply that will support everything once the build is finally finished and I am unsure if what I have will cover it.

My current build is as follows:

CPU: i5-3570k (Plan to OC to 4.0 or 4.2 GHz minimum)
MoBo: MSI Z77A-G45 Gaming, LGA 1155
GPU: EVGA ACX GTX 770 Superclocked (Starting with 1, plan to SLI later)
RAM: Corsair Vengeance 1600 8GB
SSD: Samsung 840 Pro 256GB
HDD: Western Digital 1TB Blue 7200 RPM
PSU: Corsair HX750W Gold
Misc:
Asus DVD-RW drive
Hyper 212 EVO CPU cooler, 1 120mm Fan
4 200mm Red LED fans, 1 140mm Fan (Case fans)

I also plan on adding an X-Fi Titanium HD sound card at some point.


Now if I did my math right, 750W's should be JUST enough for the Superclocked cards, my CPU overclock, all my extra stuff (Sound card, drives, ect...)

However I'd like someone to double check me and point out an area I might be able to penny pinch a little more in. I am familiar with almost all the aspects of what I should be looking for, but I am relatively new (A+ Cert last month and hands on schooling, no practical application except cleaning dust) to building computers from scratch and would appreciate any extra advice that could be offered.

I'd like to note, also, that despite saying $2000 the parts will not add up to that. I am getting a monitor, keyboard, and headset with it that is running me up the extra $400 or so dollars.

Thank you for the help in advance!

a 750w will not be JUST enough. It will be fine with your setup and will provide u some headroom as well. However, one thing that I noticed is your CPU cooler, better replace this with some good HS cooler if u intend to OC.

Big reason I settled on the EVO was the price point. Most of the reviews I've seen on it have been good for small OC's (like 4.0) which is all I'm really aiming for right now. If need be I'll just not OC my CPU and get a better closed liquid or high end air cooler later.

Thanks for the answer though. Out of curiosity how did you go about figuring up the requirement?
 
It might be in your best interest to go with LGA1150 parts instead of 1155: They will run a bit cooler, and give you a little more performance at stock speeds. Take a look at these:

OR if you can live with a little lower or no overclock:

With any luck Intel won't discontinue THIS socket in two years or less.

If concerned about power, and you like the HX750 Corsair, then go up a notch to the HX850. This will certainly give you enough excess power for SLI and other things you might add.

You can save some change, though, with this unit. XFX is manufactured by Seasonc and is very good.
