Thermaltake TPD-0550M 550W

A 550W unit with 80+ Gold efficiency certification and semi cabling. 550W covers mainstream builds with a modest GPU. It uses the ATX form factor — confirm your case lists ATX support. Power supplies are the wrong place to cut corners — efficiency certification correlates with build quality and warranty length.

PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores. Thermaltake backs the product through its standard warranty channels; check the listing for region-specific terms. The full specification sheet below breaks out every listed detail, and the compatibility checker flags conflicts with parts already in your build.
