Title says all.

Before I'll explain the case, is there actually anyone who thinks is experienced enough to assist in pc building stuff?

Alright. Giving you an undetailed version at first. More info coming when required.

I stared 3 months ago.
Stuff i already had was a perfectly working 750w Corsair PSU.
EVGA GTX 960 SSC
Samsung 840 EVO 250gb
Some badass noctua air cooler

Stuff I bought newly
i5 6600K
ASRock extreme3 z170
kingston hyperx 2x8gb 2133mhz ddr4

Just forget about the case, I'm breadboarding on the motherboard packaging covered by the plastic the mobo was in.

Built the shit. Fans spin up for a half second -> shut down -> not working. Tried everything google mentioned, even opened a tom's hardware thread. No real help.
RMAd the board because thinking it was DOA.
Got exchange board. DOA. RMAd again.
Got a refund.

Bought a Gigabyte GA-Z170X-UD3.
Built the shit. Fans spin up for a half second -> shut down -> not working.

wat. halp.

It's like the 10th PC I built. All working. Not this time.

It's a little different now since I'm running the Gigabyte now, but basically: halp.

Well. I don't know how to fix this problem, fans work fine for me. Maybe it's the psu not having enough juice to output. ... Seriously I wish I could help. Did you cancel static while building. ... Etc

Run all the general diagnostics: MemTest, clear CMOS, flash BIOS, check POST code (my board has error codes for whatever the reason is when it won't boot), try with another CPU, without GPU, disconnect devices one by one if it's hardware related, assuming the PSU is still delivering correctly. I'd incline towards saying you got another DoA board, but eh, that'd be some real bad luck. Could be the CPU, maybe bent pins or something.

Cancelled static? Always
Different wall output? Tried
Bent pins? Nah
Everything else either done or impossible.

I dont get error POST beeps. I dont get numbers on the diagnostic LEDs. It powers off too early, but corsair power tests show the PSU is fine
 

uh huh oops lol

Its not. Checked the 2 diff modules a thousand times with all slots.

Also the ethernet cable successfully links when the PSU is turned on.
So mobo actually is successfully powered i guess

In the end it seemed like the CPU cable from the PSU was broken.


I got a different PSU (EVGA 650 GQ) and MB (GA-Z170X-UD3) now and have different problems:

The MB-Speaker, if it doesn't get stuck during POST at BIOS Splash Screen, beeps 5 times (long). RAMs not the problem, CPU can't be the problem too because it was working without HDDs and GFX card before.
Now when i plugged in a GTX 960, 2 HDDs, 1 DVD-drive and 1 Blu-Ray-drive i get the 5 long beeps - removing GFX card and HDDs just made the PC boot up successfully.

For my specs 650w just have to be enough, or am I wrong?

GA-Z170X-UD3
i5 6600K
EVGA GTX960 SSC
2x 8GB Kingston HyperX 2133MHz (i guess) DDR4
1 Samsung 840 EVO 256GB
2 Toshiba X300 4TB
1 LG DVD drive
1 Samsung Blu-Ray drive
2 CPU fans
4 Case fans
USB mouse
USB keyboard


Mr. Google says: Recommended PSU Wattage:438 W
so where the heck is the problem? >_>

Gigabyte seems to say:
5 short beep :CPU error

If it was your PSU now having enough maximum output, you'd know for sure, and things would fry.

Check for bent pins. Then try with GPU, no HDDs, and with HDDs, no GPU.

650w is fine for my 780. Depends on the PSU quality and efficiency, and amperage on the +12v.

i somewhere read it could also mean PSU or RAM error, depending on which MB exactly.

how can it be the CPU if i am on that PC at the moment, working totally fine without HDDs, only SSD, no GFX card, 1 8GB RAM module in the 3rd slot...


it stops working if i put that RAM in the 1st slot and another in the 2nd - then again; it already did work before. wat?

To be fair the faulty PSU probably fried your CPU and MOBO. The different brand of MOBO most likely had some safeguard.

i really doubt that because 5 seconds before trying that new build with that faulty PSU i have used it in another build which was perfectly fine.
i couldnt believe its broken because it was still workign like seconds before i tried it with that build... but well.. technology. it breaks 5 seconds after the warranty runs out. always.
