Montech CENTURY 650W

This is a 650W unit with 80+ Gold efficiency certification and full cabling. It uses the ATX form factor — confirm your case lists ATX support. 650W covers a 220–300W GPU and a midrange CPU comfortably. Skimping on the PSU is a false economy; better efficiency ratings usually mean better components and longer warranties.

Its $63.90 price tag places it squarely in mid-range territory. Use the PlanMyPC system builder to verify it works alongside your other components and to keep a running tally of the cost. Warranty coverage follows Montech's standard policy — confirm regional terms on the listing. Scroll down for the complete spec table; the builder's compatibility checker will warn you about any conflicts with components you have already picked.
