A 550W unit with 80+ 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. A dependable power supply protects everything downstream, and efficiency tiers are a decent proxy for overall build quality.

At $159.00 it sits in the high-end power supply bracket. PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores. Warranty coverage follows Cooler Master's standard policy — confirm regional terms on the listing.
