Tom's Hardware and Hardware Busters both rate the EVGA SuperNOVA 850 G7 highly for the performance it packs into a compact body. Efficiency and build quality hold up, and it stays reliable under load. What it lacks is PCIe 5.0 support, and reviewers measured high inrush currents. Gamers who need power in a space-saving footprint should buy; anyone who needs latest-generation PCIe connectors should look elsewhere.

Strengths
  • — Full power at 47 degrees Celsius
  • — Top overall performance
  • — Good build quality
Watch-outs
  • — No PCIe 5.0 connectors
  • — High inrush currents

The Seasonic Focus GX-850 V4 holds full power at 46°C and is ready for ATX v3.1 and PCIe 5.1, with high build quality and good ripple suppression.

  • — High build quality with OptiSink technology for better heat dissipation
  • — Good ripple suppression
Watch-outs
  • — Increased MSRP
  • — Not competitive overall performance
