Overview

A 850W unit with 80+ Gold efficiency certification and full cabling. 850W covers a 300W+ flagship GPU plus a high-end CPU with margin to spare. 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.

Expect to pay around $129.99, which lands it among high-end options. PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores. Support and warranty service run through Corsair, with terms that vary by region. Every published spec is tabulated below, and compatibility against your current part list is checked automatically.
