Rosewill Capstone 450W

This is a 450W unit with 80+ Gold efficiency certification and non-modular cabling. 450W 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.

At $53.99 it sits in the budget power supply bracket. Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing. Support and warranty service run through Rosewill, with terms that vary by region. Scroll down for the complete spec table; the builder's compatibility checker will warn you about any conflicts with components you have already picked.
