Power supply for dell optiplex 740?

[chvrches]

My power supply on my old computer gave out some time ago and I'm looking to get a new one. I don't know too much about them but it's a dell optiplex 740. I'm pretty sure it's the smallest one of the three. If someone could help me out on a power supply to buy for it, I'd really appreciate it.

The above was for the Mini Tower which is the biggest of the three. I'd suggest getting another Dell PSU from someone who offers a warranty of some kind. Shop using the Dell part number so you know it will fit.
