Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.

Could be ANYTHING.
Is the PSU the only new part, or the whole build?
Did you do ANY troubleshooting yet?

Right. But that can be a loose connector, a short in ANYTHING that's getting power from the power supply (dead hard drive, frayed cable, etc.) a dead CPU, a dead motherboard... ANYTHING.
Troubleshooting needs to be done starting with unplugging EVERYTHING from the PSU and EVERYTHING from the motherboard except for the bare essentials. Power to the motherboard, CPU in socket, no RAM, no video card, no IDE cables, etc., no power to any drives, lights, etc. and then see if you can get power. With no RAM or no video card, you should at least get a beep out of the motherboard.
If not, at least you know it's the PSU, the motherboard or the CPU.
If it's a new build, I would pull the motherboard out of the case to make sure whomever built it didn't ground out the bottom of the board on the case or an extra stand-off.
If it still doesn't power up, you need to unplug the power supply from the motherboard and jumper the green wire to a black wire to see if you can get the fan in the PSU to even spin up. If it doesn't, then I would say the PSU is dead.
