Overview
This is a 300W unit with 80+ efficiency certification and non-modular cabling. 300W 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 with the rest of your parts automatically. Warranty coverage follows Rosewill's standard policy — confirm regional terms on the listing. The full specification sheet below breaks out every listed detail, and the compatibility checker flags conflicts with parts already in your build. If this power supply is not quite the right fit, the category page lists close alternatives at similar prices for a quick side-by-side comparison.
