Power supply question

Hello All,

I'm just putting the finishing touches on my new build and I wanted to confirm that my power supply should be enough to power this system without difficulty. I don't believe this will be an issue, but I'd rather leave it to the experts, and besides when you're sinking money into a new build the last thing you want to have happen is lack of power, right?

So here's the build:
Processor - I7-3770K
Mobo - Asus Z77 Sabertooth
Ram - G.Skill Sniper DDR3 1600 (8 gigs)
GPU - EVGA GTX 670 FTW+ (just one, no SLI)
Optical - Asus cd/dvd burner, nothing special
Storage - Intel 520 series SSD
PSU - BFG 650 watt, can be found here - http://www.newegg.com/Product/Product.aspx?Item=N82E16817702018
Case - Antec Nine Hundred (with additional 120mm side mount fan added)
(peripherals include tw 23" 1080 monitors but will only game on one, logitech G510 keyboard and Razer Naga mouse......if interested)

I don't intend to do any overclocking right away, as I would like to enjoy it at stock speeds for a bit and OC as needed (if I run into a situation where I'm seeing a performance dip). But what do you guys think, I should be good with the PSU I have currently and upgrade if/when I decide to SLI?

Any thoughts, feedback, advice welcome, and thanks!

  1. I have not heard or seen any BFG branded PSU's.
    also dosn't look like it meets bronze standard.

    I would go for an OCZ, Corsair, something in 600w or above is fine.


    both good products
  2. That is an old low quality powr supply. BFG has been out of business for at least 3 years so there is also no type of warranty. I would not use it especially in a high end build like yours.

    Stick with Corsair, Seasonic, PC Power and Cooling, XFX, Silvrstone, Enermax, OCZ, Antec or the 80 Plus Gold rated Rosewill units for quality. As said above 550-600 watts is what you need. Go with a 750w unit if you ever plan on adding a second GTX 670.
  3. Well you both confirmed what I suspected, it's time to upgrade. I think I'll probaby bite the bullet and go over kill (900 - 1000 watt), and shop around a bit like I did with the other components.

    Good feed back, much appreciated.
  4. http://www.newegg.com/Product/Product.aspx?Item=N82E16817182200&Tpk=rg630

    More than enough to power your entire rig for only $50.

    Also, it's not good to go overkill as that tends to make your PSU less efficient.
  5. I think I'll aim for a 750 - 850 watt in that case, as I might end up running 2 GTX 670's at some point, if I'm going to buy one I might as well build for the future.

    I'll have to do some shopping when I get home, see what I can find in that range for a quality psu with decent pricing.
  6. Not sure where you are but if you in the US this is a really good deal right now.

    Corsair HX 750 80 Plus Gold certified and fully modular for $105 after rebate.


    Hardwaresecrets Golden ( highest ) award. Easily pulled over 900 watts in testing.


    10/10 from Overclock3d.net + best in class award.


    Now those reviews while still valid are a few years old. If you just want the best of the best the Seasonic Platinum and X series take those awards these days. The 80 Plus Gold X series 750w model runs about $150 and the Platinum ( 80 Plus Platinum certified obviously ) is generally about $200.
  7. This should be enough to power your build. Only 70 after rebate.
  8. Yeah after doing some checking around I think I'll end up getting a Corsair 750 watt, either TX or HX (with the holidays coming up I'll have to watch my spending a bit). I figure either psu's should be enough to power my current build without issue and I'll still have enought head room to throw an additional GTX 670 in should I decide to SLI down the road.

    Thanks for all the help folks!
