Is this enough power?

[Hotshot19]

I need help to pick a power supply for my build, I was looking at these three.

Build specs

Screen: I need a good sized 1ms screen

Video card: One GTX 780 for now in the future probably will end up with three or at least two!

Motherboard: Gigabyte Sniper 5

HDD: 1 Tb WD for windows

HDD : 2 Tb WD for storage

CPU : 4770k

CPU cooler: going to use the one from intel till I get my custom loop setup.. Wont over clock right away

RAM: G skill sniper 2400 16gb

Case: Corsair c70


I need enough power to run two to three good video cards in the future... Also that will handle the over clock and my water loop plus HDD's with no problem.. I'm not sure if I'm going to get the GTX 780 right away but I need the power to be able to handle them down the road.. Thanks for any advise! I really want too order my build now the only thing holding me up is the PSU...

For three GTX 780s, you'll need much more power than that - each card can consume up to 270W each.

Therefore, you'll need about 1000W.

 

[JRAtk94]

Probably a bit more actually.

 

[Hotshot19]

So should I get the corsair 1200i?

 

[JRAtk94]

Yeah, that would be a safe choice.

 

[Hotshot19]

seems over kill if I only run two 780s in sli ..... Any other input?

 

[JRAtk94]

You won't need three 780s to be honest, unless you run multiple monitors at a high resolution.

For two 780s, I'd recommend 750 to 800W.

 

[JRAtk94]

This would be a good choice - 750W, 62A on the 12V rail, and fully modular. 80+ gold as well.

However, if you'd rather not have a modular PSU, these would be a close substitute -

http://pcpartpicker.com/part/xfx-power-supply-p1750xxxb9 (semi-modular)

http://pcpartpicker.com/part/xfx-power-supply-p1750snlb9 (non-modular)

These are both 80+ bronze, however.

^ this one is onsale for 110$ usd

or for about 160 I can get a 850 what do you think?

 

[JRAtk94]

750W is perfectly sufficient 😛

Those PSUs I suggested are cheaper, and of similar, if not superior quality.

Will this handle three 780s in SLI? Also Can I use corsairs cable kit with this PSU since there both ATX?

 

[JRAtk94]

Yep, that should easily run three 780s.

And I would assume so, yes

 

[Hotshot19]

the reason I keep leaning towards corsair is I hear bad results with the xfx some catching on fire.... So I'm really considering just doing the corsair 750w gold http://www.newegg.com/Product/Product.aspx?Item=N82E16817139010

its 110 and if it will run everything I have water loop HDD's etc then maybe I should get that cause I don't know if I ever will get the chance to run three 780s anyway... So maybe the 750 is a better choice? I'm just really confused on what psu to buy because like I said I might not get to run three SLI but my board supports up to 4 way, so If I do I'd be hitting a brickwall with the 750... On the other hand I wont have two 780s for a long time so its really a cons/pros thing I guess

 

[Hotshot19]

is cooler master psu good ? if so what about this one

[JRAtk94]

XFX are some of the best power supplies in the business (because Seasonic make them), so I don't see why that would be the case.

Corsair are a good choice too though

I'd also recommend Seasonic, since they are the undisputed leader in PSU manufacture, but they're quite expensive.

And I wouldn't go with Coolermaster - they're good, but not as good as Corsair/XFX/Seansonic etc.

Antec and OCZ are also good

 

[Hotshot19]

Odd time to change my mind but, I'm seriously considering running three of these (http://www.newegg.com/Product/Product.aspx?Item=N82E16814130937 )

What power would you say I need still a 1000+ Or should I just grab a 1200 now while I have the cash? It's possible I may decide to change my mind again and get a card that I can run in quad sli...
