Thermaltake Smart 500W

This is a 500W unit with 80+ efficiency certification and non-modular cabling. It uses the ATX form factor — confirm your case lists ATX support. 500W covers mainstream builds with a modest GPU. Skimping on the PSU is a false economy; better efficiency ratings usually mean better components and longer warranties.

Expect to pay around $39.99, which lands it among budget options. Use the PlanMyPC system builder to verify it works alongside your other components and to keep a running tally of the cost. Thermaltake backs the product through its standard warranty channels; check the listing for region-specific terms.
