Product Overview

The Inter-Tech ASPOWER U1A-C20500-D is a 500 W PSU with 80 PLUS Silver certification and efficiency of up to 92 %. The manufacturer describes it as a server power supply, and its compact 100 x 40 x 205 mm body with a single 40 mm temperature-controlled fan sets it apart from standard ATX units. It delivers the full 500 W on the +12 V rail (40 A) and uses active PFC.

With a 24-pin ATX connector, a 4+4-pin 12V connector, two SATA plugs and four 4-pin 5.25″ connectors, it suits compact or server-style systems rather than gaming builds with a modern graphics card, as no PCIe power connectors are listed. Protection covers OCP, OVP, OLP/OPP, SCP and OTP. It accepts 100-240 V input, has a mains switch and weighs 1.3 kg.
