Overview

A 750W unit with 80+ Platinum efficiency certification and full cabling. It uses the SFX form factor — confirm your case lists SFX support. 750W covers a 220–300W GPU and a midrange CPU comfortably. Skimping on the PSU is a false economy; better efficiency ratings usually mean better components and longer warranties.

Expect to pay around $411.00, which lands it among premium options. PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores. Seasonic 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.
