Raidmax RX-530SS 530W

This is a 530W unit with 80+ efficiency certification and semi cabling. It uses the ATX form factor — confirm your case lists ATX support. 530W covers mainstream builds with a modest GPU. Skimping on the PSU is a false economy; better efficiency ratings usually mean better components and longer warranties.

At $9.59 it sits in the budget power supply bracket. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current power supply prices across retailers. Raidmax backs the product through its standard warranty channels; check the listing for region-specific terms. Scroll down for the complete spec table; the builder's compatibility checker will warn you about any conflicts with components you have already picked.
