What will an Antec PP253X Power up??

[Southpaw]

hey All,

Wife has an Enlight 7237 with an ailing Celeron2-566>>850 on a BX6R2 Motherboard..this is run by the Antec 250Watt power supply

I am looking for another mobo/cpu (AMD) that can be run reliably by an Antec 250W supply.....

any hints???? thinking of somehitng like a Duron 800-900...

thx
