Antec CSK 550W

This is a 550W unit with 80+ Bronze efficiency certification and non-modular cabling. 550W covers mainstream builds with a modest GPU. It uses the ATX form factor — confirm your case lists ATX support. Skimping on the PSU is a false economy; better efficiency ratings usually mean better components and longer warranties.

Its $118.02 price tag places it squarely in high-end territory. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current power supply prices across retailers. Support and warranty service run through Antec, with terms that vary by region. Every published spec is tabulated below, and compatibility against your current part list is checked automatically.
