Antec TruePower 330W Power Supply
 

Today we're going to be checking out a budget-oriented Antec power supply called the TruePower 330W PSU. It's doesn't have flashy lights, LED fans or other gimmicky items. With a retail price of $73 CDN ($57 US) the Antec TruePower is not the cheapest 330W PSU around, but it should be among the best you can get in its class.
