Antec NeoECO 400W

A 400W unit with 80+ efficiency certification and non-modular cabling. It uses the ATX form factor — confirm your case lists ATX support. 400W 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.

Expect to pay around $79.99, which lands it among mid-range options. Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing. Antec backs the product through its standard warranty channels; check the listing for region-specific terms. The full specification sheet below breaks out every listed detail, and the compatibility checker flags conflicts with parts already in your build.
