790, using an ATX power supply on 790 motherboard

[mg36845]

Hello, I am rather new to computers and need help ordering a new power supply that wont mess with my motherboard as I have read that ATX power supplies don't work on dell mother boards. Can anyone please help?
I have a Dell HY9JP Optiplex 790 motherboard.

Dell PSU's were propietary...you had better check the pinouts before frying a perfectly good board...just sayin
