Building a new computer, and looking into PSU's for the final part. Not too sure of my GPU yet, but it will either be a GTX 580, or a GTX 680, and I would like to have the ability to get a second one and run it SLI in the future, if the price premium on a compatible SLI PSU isn't too high. Anyway, here are my current specs.

Intel i5-3570k
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Cooler Master Hyper 212 Plus
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

16GB Corsair Vengeance DDR3 1600
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

ASUS Sabertooth Z77 Motherboard
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

LG Black 10x BD-ROM Drive
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

ASUS 24x DVD Burner
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Crucial M4 CT128M4SSD2 2.5" 128GB SSD
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Western Digital 320GB 7200RPM HDD
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Antec 900 Case
http://www.newegg.com/Product/Product.aspx?Item=N82E168...


Also, worth noting:


4 x 120mm TriCool Fan's
1 x 200mm Fan
Will probably add another SSD or HDD in the future.
Would like to add another GPU for SLI in the future.
Will be overclocking the CPU to upwards of 4.0GHz.
Will possibly be overclocking the GPU.



Anyway, all that's left for me to buy is the PSU, and the GPU. I probably won't purchase the GPU until after June 1st, but I'm fairly certain I'll be getting either a GTX 580 or GTX 680. At the moment I am using a GTX 275. For the PSU, I would like something that will support SLI in the future if I decide to eventually go 2x580's, or 2x680's, however, if there is a PSU out there that is $50'ish less or more, I would probably drop that and just use one single card and save some money.

Any help is greatly appreciated!!

The Sandy Bridge CPUs are better for OC than the Ivy Bridges...the Ivy's heat up faster since Intel switched the Thermal interface material in mfr process. You just missed a great deal on an Antec Neo Eco this morning: $35 for a 620W PSU with 48A on the 12V rails. Minimum specs for the single GTX580 (will use this to spec the PSU since it is more power hungry): 600W PSU, with at least 42A on the 12V rails and (1) 6-pin and (1) 8-pin PCIe connectors. Add about 5A for the OCs....The Corsair TX650W is one of the better options in this range: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
$75 after MIR and has 53A on the 12V rails. If you want to SLI, then you will need to step it up to the TX850. Highly recommend going with the GTX 680 vice the 580.

For a system using two GeForce GTX 680 graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 750 Watt or greater power supply that has a combined +12 Volt continuous current rating of 53 Amps or greater and that has at least four 6-pin PCI Express supplementary power connectors.

For a system using two GeForce GTX 580 graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 900 Watt or greater power supply that has a combined +12 Volt continuous current rating of 65 Amps or greater and that has at least two 6-pin and two 8-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important factor.

There's no $50 PSU that will come close to meeting those requirements.

Make sure that the PSU you get has at least four PCI Express supplementary power connectors so you don't have to resort to using the dual 4-pin Molex peripheral to 6-pin PCI Express adapter cables.

no offence mate but your build is kinda unbalanced.let's see how-
1-IB runs hot and you have chosen 212+ instead of EVO.why?if you are an overclocker then go with 2500k.
2-super expensive board with features that are 'almost' useless.you can get the job done with a cheaper board.some thing like this,gigabyte ud3gh-z77-
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
3-you really need a blu ray?i mean if you are not a serious movies freak then a cheap a$$ burner will do fine-
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
4-why two optical drives?
power supply is one the most important part of a rig,a bad psu and i am sure you will fry your pc and will cry like a girl.i am not joking,it's better to first get the best 'core components' you can get for your money then focus on fancy things.gtx 580 is definitely better than gtx 580 in almost every aspect.a 680 SLi setup will run fine on a 'quality' 750w unit at stock speeds but assuming that you are going to overclock,i will recommend what guru3d does-
Quote:
Here is Guru3D's power supply recommendation:

GeForce GTX 680 - On your average system the card requires you to have a 550 Watt power supply unit.
GeForce GTX 680 SLI - On your average system the cards require you to have a 750 Watt power supply unit as minimum.

but-
If you are going to overclock the GPU or processor, then we do recommend you purchase something with some more stamina.
otherwise-
What would happen if your PSU can't cope with the load:
bad 3D performance
crashing games
spontaneous reset or imminent shutdown of the PC
freezing during gameplay
PSU overload can cause it to break down

the best bang for the buck 850w power supplies are-
xfx pro 850w(rebranded seasonic but cheaper)-
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
$102 after rebates
or
corsair tx850 v2(rebranded seasonic)-
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
with these changes,you will have a more 'futureproof and long life rig.
i hope you got my point.if you have any questions,feel free to ask.

+1 hellfire.

i agree with all those points

This is what your Blue Ray drive can do.
