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 $59.99 it sits in the budget power supply bracket. Use the PlanMyPC system builder to verify it works alongside your other components and to keep a running tally of the cost. 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.
