Will this PSU support an FX - 8350 and a GTX 770?

[John Alexandropoulos]

Here is my future build:
AMD FX-8350
EVGA GeForce GTX 770 SuperClocked w/ACX
Corsair Vengeance Blue 4GB (1x4)
Samsung 840 Evo 120GB SSD
MSI 970A-G46
Corsair CS600 Modular 80 Plus PSU
CoolerMaster Hyper 103
Corsair Carbide 200R

My main concern is that the PSU won't be enough for the CPU and GPU, which both need quite a few Watts. I am on a tight budget and trying to keep the cost as low as possible. So, should I pick an AMD or an Intel CPU? (grabs popcorn) I repeat that I need a value-oriented system, so no 4770k budget-blowers here.

The GTX 770 needs 42A and at least 600W of power. The CX600 provides 46A on the +12V rail with 600W - you will be cutting it extremely close. Usually wattage is over specified however so it is likely that your 770 will only consume (with the other components) around 550W. You should be okay with the CX600.

The GTX 770 will not get remotely close to a 42 amp draw (504 watts)... Take a look at some real world numbers and you will see that it is capable of consuming around 250w (20ish amps). Overclocking will add to that, but not all that much. The 600w PSU will be fine.

That's not how it works. GPU amperage is based on the full system - this means graphics card, CPU, everything. While the card could in theory run on ~20A, you would be choking the rest of the system and indeed it would not boot. There is a reason that knowing the amps on the +12V rail is stressed. If you were to run SLI, you would only look at the ~20A value and add that to the 42A requirement.

The MSI motherboards have a history of failures . Use an ASUS M5A97 r 2.0

Is there any other AM3+ Mobo that supports 2-way sli? I might be adding another of these bad boys later on...

What's your price range on it? For under $150 I'd go with any of these:

ASRock 990FX Killer: http://pcpartpicker.com/part/asrock-motherboard-990fxkiller
Gigabyte GA-990FX-UD3: http://pcpartpicker.com/part/gigabyte-motherboard-ga990fxaud3
MSI 990FXA-GD65 v2: http://pcpartpicker.com/part/msi-motherboard-990fxagd65v2

Basically the lowest possible, ideally less than 100$

could i use the cx series psu instead?

Right. The GPU will be around 250w / 20ish amps with a max draw.... My point is that minus the GPU, there is no way this system will draw close to 350w. With the GPU accounted for and fully overclocked, the total draw would be closer to 450w. That is well under the "recommended"...

 

[John Alexandropoulos]

So I can use the cx600 after all? Or the cs600?

Skip the CX line with Corsair (not the best quality). TX, HX or RM series. You are probably after the TX line...
Corsair TX650 => http://www.newegg.com/Product/Product.aspx?Item=N82E16817139020
...or...
XFX 550w => http://www.newegg.com/Product/Product.aspx?Item=N82E16817207013
XFX 650w => http://www.newegg.com/Product/Product.aspx?Item=N82E16817207014
Seasonic 550w => http://www.newegg.com/Product/Product.aspx?Item=N82E16817151136
Seasonic 620w => http://www.newegg.com/Product/Product.aspx?Item=N82E16817151096

Are the XFX and Seasonic 550 watts a good choice? will they be enough?

PSUs from Seasonic and XFX are very good units. As are Corsair minus the CX line...

will they be enough?

Below is a build that is very close to what is being proposed. The estimated wattage is also listed... A 550w rated unit is plenty of power as long as you stick with a quality company and product line. If you want to plan for a second GTX 770 down the road, you will need to bump the PSU to an 850w model (consumption would be around 700w).

You do not need 850w for 770 SLI. You can SLI 780s perfectly safely on 750w. I would not consider anything over 750w even if you plan to SLI 770s in the future. A 770 at MAX load will pull no more than 200w. 200x2=400w There is no way the rest of the system even if heavily overclocked will get anywhere close to 750w.

I agree to stick with XFX, Antec, and Seasonic. You can go Corsair, but stay away form the CX, CS, RM units as they all use the same cheap low quality capacitors.

Thanks guys! You are giving me life-saving advice right now! I think I will go with the XFX ProSeries 650W Core Edition Full Wired.

That's a great choice.
