Rosewill Stallion 400W

This is a 400W unit with 80+ efficiency certification and non-modular cabling. 400W 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.

Expect to pay around $49.99, which lands it among budget options. PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores. Warranty coverage follows Rosewill's standard policy — confirm regional terms on the listing.
