I know minimum recommended is 600W, same as on GTX780Ti Classified but people install in Hadron.
PSU inside is not some garbage. With i7-4790K on Turbo Clock and 2xSSD I can bet that could work.
Not only in Hadron AIR.
If someone change pump(as people done successful in Hadron Hydro) with 240mm radiator is possible to build and small loop. 
You see little art on pictures above. 
240mm radiator for CPU/GPU cooling is not nicest solution but could keep low temps without problem, around 50-55C.
And for 4790K and for TITAN X SC. Fans should be with low power consumption, SSD power consumption is funny, DVD-RW could be external on USB 2.0 and that's it.

We run TITANX's in the Hadron all the time :) No problem.

Ello
 
Is the Swiftech H220-x fit into the EVGA HADRON HYDRO? I find nothing on the net.
Thx a lot.
 

 
 
 

Upgraded to Z97, 4770K and 16GB memory
 

 

That's your Hadron Jacob?
It's nice, excellent is for office gaming RIG or backup PC or such things.
For someone and main RIG. Next 5 years popularity of small cases will be bigger and bigger.

Yea, I use it as a living room PC.

Maybe you could replace later with i7-4790K. 
He don't need to overclock because extremely high Turbo, but if you keep your on 4.4GHz that's same.
 
 
Performance difference between i7-4790K and i7-6770K will be very similar.
Except Z170 Stinger will support DDR4, but from performance side nothing special,
i7-6770K will work on 4.2 Turbo and people will probably try to push on 4.5GHz.

Still not done modifying the case but this is most of what I have done so far :)
 

I like Hadron case more and more...
But I would install reference card and single 120mm radiator AIO or Noctua NH-U9S.
She is small but could cooldown i7 up to 4.5GHz without problem.
This is NH-U9S in Hadron...fit even with second fan...they spin on 1600RM or 2000RPM MAX speed but they are not loud at all.
With such good cooler 4790K on Turbo clock could work without problem.
 

 
Hadron Hydro is nice too because leave option and for watercooling, but Air is real small case.
I saw one guy install watercooling and in Hadron Air. Example i7 mainsteam I would build only in mITX factor...
Because dual channel memory 2x8GB is enough for everything. ASRock make some X99 mITX board but with only two slots and on that way customers can't use proper all advatage of X99.
Only I think PSU need to be sleeved with someone who know crimp wires... I saw even Hadron PSU in some store... only PSU...
Sleeve wires occupy only 1/3-1/4 place of normal cables, and for such little case that's very important.
That's advantage and of EVGA Sleeve Power Supply Cable Set... They are excellent for small rigs as obsidian 350D and all similar cases with Micro ATX motherboards because cables use so small place and fit in every little corner between motherboard tray and side panel without problems...
