Can my Thermaltake 750w PSU model SP-750P work in a dell Precision T3500 workstation?

I couldn't find anything about Dell Precission t3500 workstation requirements. Is the 750w enough. Can my Thermaltake 750w PSU model SP-750P: Smart 750w W/Active PFC. It as +5V 22A, +3.3V 22A, +12V 62A. -12V 0.3A and +5VSB 2.5A. It as a 24pin and ATX 12v 4+4 pin work in a dell Precision T3500 workstation?

Is there a reason the t3500 need a lot more power on other rails like +5v 25A compare to other PC that never uses more than 20A?
