Product overview
Released in October 2016, the CORSAIR VS400 belongs to the VS Series (SKU CP-9020117-NA), Corsair’s entry-level ATX PSU family. It sits firmly in the budget tier with 80 PLUS White efficiency, non‑modular cabling, and a 3‑year warranty—built to power basic PCs cost‑effectively without extra frills.
It’s a good fit for budget ATX builds where 400 W and a single PCIe power lead are enough, such as office systems or low‑power GPUs. Notable capabilities include active PFC, a thermally controlled 120 mm sleeve‑bearing fan, and standard protections (OVP/UVP/SCP/OPP/OTP). As a pre‑ATX 3.0 design, it lacks native 12VHPWR support and isn’t intended for modern high‑end GPUs. Rated for full output at 40°C. Discontinuation status is unconfirmed.
