Hello, im building my first pc my specs are a sabertooth z77 mobo, some corsair dominator 12gb 1600 mhz memory ddr3 , a gtx 670 ftw edition gpu, intel i7 core 3770k 3.5ghz, and for my cooling for my cpu im using a hyper 212 plus heatsink fan from coolermaster, and a western digital 2tb 7200 rpm caviar black internal hdd. what power supply units do you guys recommend heres the one i plan on getting tell me wut u think http://www.amazon.com/gp/product/B001NJ0CYG/ref=ox_sc_act_title_7?ie=UTF8&smid=A3SNNXCKUIW1O2
 
Here is Guru3D's power supply recommendation:

GeForce GTX 670 - On your average system the card requires you to have a 500~550 Watt power supply unit.
GeForce GTX 670 2x SLI - On your average system the cards require you to have a 700 Watt power supply unit as minimum.
GeForce GTX 670 3x SLI - On your average system the cards require you to have a 850 Watt power supply unit as minimum.

Remember, if you are going to overclock the GPUs or processor, then we do recommend you purchase something with some more stamina. The minute you touch voltages on the CPU or GPUs, the power draw can rise real fast and extensively. Source: http://www.guru3d.com/articles_pages/geforce_gtx_670_2_and_3way_sli_review,4.html

even if you double the power for going SLI and overclocking, which it won't, don't know why a 600-650 watt PSU can't handle 456 watts . . . that is 76%-70% load.

The cieling on that CPU is another 120'ish for wattage. Some fans? Some RAM? A heatsink? A dvd, cd player?

Uhoh.

If you're going to SLI, you should go with the 750 watt, period.
 
nVidia itself recommend 500W for a single 670. Add 170W for SLI & recommended is 670W.

For testing conducted for SLI 670, the resulting system consumption for SLI is 433W of which 293W are attributed to the gpu cards.

If you use this psu calculator considering OP components, the result is 664W (overclocked processor & used 680x2 to simulate gpu OC:

All points out to 750W being more than enough and a 650W pushing your luck.

1. the OP never mentioned SLI so suggesting a PSU for a SLI set up is not what they are looking for/ inappropriate.
2. card manufactures will not take into account quality PSUs which will have a stronger 12 volt rail and give suggestions for "weaker" units to compensate; a quality PSU will provide 80% of it power from the 12 volt rail, "weaker" ones will be less. the same can be said for online calculators.
3. when looking at benchmarks or reviews, use one that has the same wattage for the system power. the guru 3d has a Core i7 965 / X58 system overclocked to 3.75 GHz which will use more than a i7-3770K @ stock; as the OP spec'd.

so as the OP asked a quality 500-550 watt PSU is what they are looking for, not an expensive 750 watt SLI set up.

and seriously - if you are going to give high end suggestions and not mention a season X series . .then shame on you all. :lol:



p.s. don't get butthurt over an apprentice "laying down the law" this ain't my first rodeo . . ;)
 
I know what he asked i was clearing up the even if you double the power for going SLI and overclocking, which it won't, don't know why a 600-650 watt PSU blah,blah,blah, i think your confused ;)
