This is a 450W unit with 80+ Gold efficiency certification and full cabling. It uses the SFX form factor — confirm your case lists SFX support. 450W covers mainstream builds with a modest GPU. Power supplies are the wrong place to cut corners — efficiency certification correlates with build quality and warranty length.

Its $139.99 price tag places it squarely in high-end territory.
