Silverstone SX1000R-PL 1000W

This is a 1000W unit with 80+ Platinum efficiency certification and full cabling. It uses the SFX form factor — confirm your case lists SFX support. 1000W covers a 300W+ flagship GPU plus a high-end CPU with margin to spare. A dependable power supply protects everything downstream, and efficiency tiers are a decent proxy for overall build quality.

Its $321.11 price tag places it squarely in premium territory.
