SeaSonic FOCUS SGX (2021) 650W

A 650W unit with 80+ Gold efficiency certification and full cabling. 650W covers a 220–300W GPU and a midrange CPU comfortably. It uses the SFX form factor — confirm your case lists SFX support. Power supplies are the wrong place to cut corners — efficiency certification correlates with build quality and warranty length.

Its $99.99 price tag places it squarely in mid-range territory. Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing. Warranty coverage follows Seasonic'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.
