Kingwin AP-550 550W

This is a 550W unit with 80+ Platinum 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.

PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores. Kingwin backs the product through its standard warranty channels; check the listing for region-specific terms.
