Amazon offers Prime members the EVGA 400 N1 400-watt ATX Power Supply, model no. 100-N1-0400-L1, for $19.99 with free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $10.23.) That's about $4 under what you'd pay in local stores. It features a 120mm double ball bearing fan, four PCI-Express connectors, 24-pin ATX connector, 8-pin EPS (CPU) connector, and three 4-pin peripheral connectors.
A close price: Newegg has it for $19.99 plus $1.99 for shipping.
