Have a bunch of Power Supply units 300 watt thereabouts, for 20 each. will work in your PC computer or for various types of projects these guys can power for you. Need something higher wattage, I do carry specialty replacement PSU for Dell Precision and Lenovo Thinkcenters, I may have the one you need. Pm me for inquiries, ask about our new string of gaming computer towers built this week, and business class Lenovo and Latitude, Precision and Alienware laptops available. North Nanaimo.
