Thermaltake Toughpower SFX 550W

A 550W unit with 80+ Gold efficiency certification and full cabling. It uses the SFX form factor — confirm your case lists SFX support. 550W 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.

Its $171.00 price tag places it squarely in high-end territory. PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores. Warranty coverage follows Thermaltake's standard policy — confirm regional terms on the listing. Every published spec is tabulated below, and compatibility against your current part list is checked automatically.
