EVGA SuperNOVA 850 G6
Ranked #5 in Best 850w Power Supplies
EVGA SuperNOVA 850 G6
3 sources2 derived$269.99as of Jun 28

Tom's Hardware found the EVGA SuperNOVA 850 G6, an 850W unit, performs well and is put together well. It's fully modular, compact, and holds voltage steady, though reviewers took issue with the fan behavior and with efficiency at typical loads. A 10-year warranty backs it, and it works in high-end builds. The problem is the company it keeps: this class is crowded.

Strengths
  • — Full power at 47 degrees Celsius
  • — Good build quality
  • — Tight load regulation at 12V
Watch-outs
  • — Fan speed profile could be smoother
  • — Efficiency at normal and light loads could be higher
  • — High inrush current with 230V

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
