StarTech ATX2POWER400 400W

A 400W unit with 80+ efficiency certification and non-modular cabling. 400W 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.

Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing. Warranty coverage follows StarTech's standard policy — confirm regional terms on the listing. Every published spec is tabulated below, and compatibility against your current part list is checked automatically. The category page surfaces comparable models near the same price, which makes shortlisting against this power supply straightforward.
