Which relay can I use ?

I want to run two computer power supplies, and have 1 turn on by a relay
when the first one is turned on.
The power supplies are 96 W and 250 W. I understand that a 12V DC always on
relay is what I need, but I am not sure what amps it needs to be rated at.

The way it will work is this. I have a 96 Watt power supply that is turned
on, and I want it to trigger an ATX 250 W power supply to come on as well.
The relay will be powered by the 96 watt power supply, and the switch in the
relay will connect the green and black wires of the ATX power supply so it
will be on. If anyone has any information on what I should be looking for, I
would appreciate it.

Here you go: Radio Shack Catalog #: 275-226

It costs $5.95 and will handle up to 30 Amps -
way more than you need.
