A lot of supplies have eliminated the white wire, so you have an unused pin across from the grey one. Try popping out the blue pin or cutting the blue wire and see if your NAS will then power up with no drives. Without doing that, the -12V is shorted to the +12V, which will typically cause the power supply to not power up. But it not powering up is what causes it to do no damage when you didn't remove the -12V.
I don't know what I was thinking when I said the +4 has two 12V wires. You are correct, it has but one. But you can generally get enough power with just two, so put that yellow one from the +4 in place of the blue or in the currently empty spot across from the grey. But if the CPU connector cable is long enough, also putting one of those yellow ones in the other position is best.

Hi,
Indeed it's a not modified supply with more cables as the original. It's a 20+4, the old one only 20 pins. But I don't have a white one (but a gray one). In the 4 pins connector I've only 1 yellow. I attach a photo.
