Bought new Power Supply Unit, won't power on. Did I buy the wrong one?
I have a Corsair CX430M PSU with 4 slots to connect in the back.

& bought a new Antec BP550 Plus PSU, which has 5 slots to connect to.

The Corsair on the left & the new Antec on the right.
I double checked to make sure ever cable (mobo/HDD/DVD/fans/GPU etc..) that was attached to the Corsair was also then attached to the Antec.
The yellow wire in the middle of that picture with 8 slot holes is from my GPU/PCI-E cable & fits into the Corsair perfectly, but doesn't on the Antec.
Luckly the Antec had a adapter that let me connect that one end & then to the PSU.
That's pretty much the only differences between the two.
There was no power when turning on my PC with the Antec.
I reconnected the Corsair back & it worked fine. Unplugged everything & made double sure where all the cable connections were & put back the Antec.
Still nothing.
I tried shuffled & re-attaching some of the cabels in the back of the Antec PSU into the red slot, but that didn't seem to work either.
Did I buy the wrong PSU? Is it not compatible with my PC or am I not connecting the right cable into the right slots in the back of it?
