Hello everyone!

To start, here is my PC Partpicker link: http://pcpartpicker.com/p/qxX2Jx

Anyhoo, as you can see I am planning on using the FX 9590 and an R9 Fury. I plan on upgrading later down the road with a second Fury (and more RAM). My question is this: Will the 1200 Watt SeaSonic be a good investment in the long run or should I go with the Corsair AX1500i? I plan on reusing the case and power supply when I do another build in the future. Thanks!

P.S. I already have a spare hard drive, so that is why it is not listed in the parts. Other comments are great to regarding the build, though I already understand that (in most cases) Intel is better (at the moment at least).

Yes, 400W, I was just rounding up, I always add a little extra power consumption when it comes to these things to give some overhead.

As stated you should be god to go on the 1200W, anything more is a little much and is true overkill as it will be unused. 1200W is just enough to handle 2 r9 furys and the processor. You should have no trouble, I would not reccomend maxing your GPU and CPU at the same time though...

Just make sure your 12Vrail is 50Amps+ and you will be fine, The 12v rail powers the CPU and GPU/fans and motor drivers, HDDS. the rest is powered by the other rails, which most if not all PSUS can handle it fine.

If your 1200W has enough power on that 12V and you have a 15-25% overhead then get it, and it will last you into the future.
Get the 1500 if you plan on crossfiring cards sometime in the future and adding watercooling/waterpumps.

Watercooling/pumps are not that energy consuming either, so you should be fine, all up to whether or not you want to future prof your PC for a future Crossfire.

Also the 1200W Seasonic can handle your 2 cards with ease, Go with the 1200. The r9 you have listed has around a max draw of 450Watts in torture testing, so 2 of them is around 900W/12V is 75amp total, your 12V rail is 100AMPS so your GPU wont be taking 25 amps itself, you have plenty of overhead and should be golden.

your math is mising the cpu. normally it is not much but remember that cpu is 225w or more!!!

which is another 19+ amps!! but the fury is nowhere near 450w even on a torture run. most i have seen is almost 400w for torutre run. 300 or less for any gaming run at the most. the 1200w is ample power and the way to go :)

i would avoid that chip if you can. a i5 6600k kills that cpu in gaming. plus with a i5 you dont need to invest in a massive power supply or a very expensive cooler. and you could actually upgrade the i5 to a new cpu in the future without switching mobo. i know you already understand this but it will be a significantly faster pc with a i5 in it. another note. you should always have ram in sets of 2. a build with 2*4 will be faster then one with 1*8

Unless you have the CPU already dont get it, they are a disaster and need expensive motherboard, PSU and water cooling and still dont perform as well as a cheaper i7.

If you do go with that CPU you need to ensure your PSU can supply more than 220w on the 3.3v rail, total wattage is less important. You also need to ensure you have a very good motherboard which supports 220w cpu's, not all AM3+ boards can run this cpu

You should have no trouble, I would not reccomend maxing your GPU and CPU at the same time though using benchmarks because then your overhead on the 12v starts to diminish.

So exact math, CPU at 100% 300W, Card at 100% 400W Second card 400W, total of 1100W/12v = 91amps max draw,
Your PSU has a 100AMP 12V Rail. thats a 9% overhead at max load on both which is good.

YES the 1200W PSU can HANDLE BOTH CARDS and your CPU.

I would like to thank everyone for your advice. I am glad to hear the the 1200 watt will be good for now and the future. AS for the RAM, I think I went down to one stick when I was fiddling with components for the sake of price. I will probably get 2 8gig sticks. Thanks!
