Hi, I am not sure if the motherboard is fried or just the psu is fried. I just assembled my computer. It has the following specs:
Motherboard: Asus z170-E
CPU: Intel i5-6500
Ram: Corsair 2x4GB DDR4 2133
SSD: Samsung 850 EVO 250GB
PSU: Corsair CX600
Graphic Card: EVGA 1060 6G ACX 2.0 SINGLE
Cooling: Corsair H60

So I just assembled all the parts and installed WINDOWS 10 and everything. While I was playing Overwatch, I suddenly heard a pop sound and the light dimmed for a few milliseconds. Computer is shut off. I tried to turning it back on, no response.
I then took a wire to test if the PSU still works. I put a wire in between the a green wire and the adjacent black wire, and turnt on the psu, the fan of the psu is not moving. Clearly, I think the psu is dead.
My question is:
1. Is my motherboard also fried out? (I see there are some protections that ASUS has, but I am not sure if those protection works)
2. Will the death of the psu caused by a short circuit motherboard?(But I do not think the motherboard is shorted, still not sure)
Thanks!

It may or may not have damage. I would hope it is not damaged. But if you heard POP, then you should be able to smell or see something. Look at good light on motherboard and see if there anything burned, and smell the PSU. If it has burned smell, I would not test it farther.

Hi. I think I heard a POP, but I did not see anything on the PSU or smell anything from the PSU. I tried to test the PSU by shorting its green and black wires(According to the guide, the fan should rotate), the fan did not rotate. There is no question that the PSU is dead. The thing I concerned is the motherboard, there are other components on the motherboard which are more expensive than the PSU... But since ASUS claims they have the 5X protections but I am not sure if that can protect short circuit(Short-circuit damage prevention
Onboard resettable fuses prevent overcurrent and short-circuit damage. This extends beyond I/O ports to DRAM to safeguard the lifespan of both your system and connected devices.)
Here is the link of ASUS Z170E: https://www.asus.com/us/Motherboards/Z170-E/


One thing that caught my attention is that, when I was game, the graphic card is drawing more power from the PSU. PSU POPPED and died? Would it just be the defective PSU hopefully?

I hope your mobo and other parts is fine, just do what Astralv say, and to test your mobo just try to borrow your friends PSU to test it, just don't risking your other parts using your PSU mate because electricity is very sensitif for PC.
