Approximate Purchase Date: By May or July

Budget Range: As it seems it's going into 2k range

Hey guys I need help building a new rig so l'd like some tips about the rig. I'm quite concerned about the PSU and Crossfire, because I don't know going for 1000w is overkill although I intend to move from (2x)280x to (2x)290x and crossfire them, I intend to crossfire 2 gpu only so as soon I move from (2x)280x I'll be crossfiring (2x)290x if got enough cooling room and if it's worth the trouble (performance wise), and slowly build a custom cooler sometime later.

System Usage from Most to Least Important: gaming, photoshop, blender, programming, surfing the internet, watching movies

Single R9 280x will require 250W of power on max load. That is for reference card, non-reference card's will consume extra 10-15 watts.

Single R9 290x will require 300W of power on max load. Same goes as above for reference/non-reference card's.

I would prefer a single powerful card for hassle free performance. Crossfire has some issues like micro-shuttering in games.

If you plan on a single card than 650W PSU will do the job. If you plan on Crossfire then I would say 800-850 Watt PSU will be needed. And if you have the money you can go with a 1000W PSU aswell, there is nothing like overkill, it will not cost you a penny more to operate a 1000W PSU vs. 850W PSU, rather it will be better to have some headroom. The more you stress a PSU the more quickly it will run out of life.

Here is a good PSU as an example :

With a single GPU there's no need to go with a liquid cooler, an Air Cooler is sufficient and risk free, as liquid coolers may leak and could takeout your valuable components.

I personally wont prefer Overclocking. Good luck.

I would avoid running AMD cards in crossfire at this time as they do have micro stutter issues. This has been largely reduced with driver updates, but it is still present. The XFX 1050W is a great PSU, but as for the AIO Kraken cooler, don't bother. A good air cooler will be just as effective. Sound card isn't required, as most current gen motherboards have fairly robust 5.1-7.1 sound solutions built in.
Take the money set aside for both the second GPU card, the sound card, and the water cooler, and instead up your video card one step, as this will be your bottleneck. You'll be happier.

So which air cooler would you recommend, AIO Kraken is unnecessary then? Won't it's heavy body risk damaging my mobo? Since I'll be doing the assembling myself.

Which PSU would be considered safe for a single card them? Maybe 750w?

If I can spare some money by choosing a lower wattage PSU, setting aside the sound card, and going for Air Cooler then maybe I could go for 290x TOXIC/TRI-X later which it's still somewhat expensive here on par with gtx 280/280ti.

Also I'm willing to make use of
2x200mm fan on top - intake
140mm fan back - intake
2x140mm fan botton - exaust
200mm fan front - exaust
140mm fan side - exaust

The hot air blowed from the gpu would be flushed down instead of going up towards the processor, would it optimize the airflow? The case would be placed on the ground bellow the desk. A 750w PSU would be enough?

I'm also concerned about durability so I would't like to expose the components nor the processor to "high temps" so I'd like to keep it the lowest possible aside from custom water cooling.

XFX ProSeries 750W 80+ Gold Certified Fully-Modular ATX Power Supply

This is sitting at less than $120 right now, and is fully modular with more than enough wattage for your needs. That will save you around $75.

An excellent CPU cooler is
Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler

Also, on the fan arrangement, try to use your top fans as an exhaust, as hot air will rise to the top on its own. May as well use that to your advantage when determining air flow.
I have the original Phantom full tower case, and if yours is similar, then the way Idirecte my airflow was in from the front and sides, exhaust through the top and rear. I never had heat problems.

Simsreaper is right about three things : 1. the choice of air cooler and 2. the orientation of fans. 3. No need for PCI sound card, MB's integrated sound is sufficient for everything.

Cooler Master Hyper 212 EVO would be my choice also, its a pretty decent cooler. And in simple physics top fan should be used as exhaust. So top and rear fan = exhaust, front = intake, side = intake.

For a single GPU no matter its 290 or 290x or 780ti a 650W PSU would be enough, but you could go with a 750W as well which will give you some extra headroom.

This would be my choice for 650W PSU, solid as a rock, and sufficient for a single GPU, else you could go with Simsreaper's choice the 750W PSU, decent as well :

PCPartPicker part list / Price breakdown by merchant / Benchmarks

Power Supply: XFX 650W 80+ Bronze Certified Semi-Modular ATX Power Supply ($109.25 @ Amazon)
Total: $109.25
(Prices include shipping, taxes, and discounts when available.)

Just keep in mind, to much fan could mess the airflow, so 3/4 fans will be enough. Good luck.

Thank you guys for your help, I decided to take the Cooler Master V850w as it seems to be build by the same OEM of XFX psu, which is Seasonic, the reason for increasing even more headroom is due to the possibility of overclocking later and "reasonable" prices of HD 7990 which is much cheaper than nvidia's 780 here, but I'll stick with r9 280x TOXIC for the time being, and due to some issues about crossfiring and prices which, I'm afraid, won't drop enough by the time I decide buying another and crossfire it, I'll stick with one beefier card and keep things simple.

As for the mobo I went for the sabertooth, the M5A99FX kinda vanished from the market at the time and those that lasted became quite overpriced, and as for the sound card I decided to go for the Creative ZXR, most onboard sound are indeed good enough for pretty much everything but I had and Audigy many years ago and I did really miss that sound board although all onboard sounds now would be on par and maybe even superior to that one.

And about overclocking the the fx-8350, I'm not quite sure about it, as I've seen it I can go somewhere 4,5ghz to 4,7ghz without messing too much with cpu voltage, and if it proves to be quite beneficial at some point I'll just attempt to do that along with some help, so I'll keep the kraken x60 to play it safe.

Yes, that's a good choice of PSU, its TIER 1 brand PSU. So it seems like you have figured out everything for your up coming build, good luck. Cheers.
