Because of my own email problems, I am unable to get Listserv to approve this
message. So I'm forwarding it to PCBUILD for "Herbert Graf" <[log in to unmask]>.

    Be carefull here, the 300 watt rating on your supply is input wattage,
assuming a 100% efficient power supply you would get 300watts output, but I
have never seen that. I recommend you don't use wattage, and add up the amps
on everything and see if you excede what is said on the supply. TTYL
