NZXT E850 (850W/80+ Gold/Digital/Fully Modular/ATX 2.x/High-End Tier) Review
Already running NZXT CAM software and want a power supply that plugs into the same monitoring dashboard, the NZXT E850 is NZXT's digital PSU built on a Seasonic-sourced platform with real-time wattage and rail data in CAM.
We think this is worth the price premium specifically for the CAM integration: you get live power draw and efficiency numbers alongside your CPU and GPU telemetry in the same app. Under the hood it's essentially a Seasonic-grade platform, so build quality is well above the 80+ Gold badge alone would suggest.
CAM Integration
The E850 reports real-time power draw, rail voltages, and fan speed directly into NZXT CAM, letting you monitor PSU load alongside the rest of your system without needing separate software or a hardware power meter.
Comparison to Alternatives
Against the NZXT C850 Gold already in the catalog, the E850 adds digital CAM monitoring and Cybenetics Platinum-level real-world efficiency for a meaningful price premium over the analog C-series. Against the Corsair AX1600i, the E850 offers similar digital-monitoring philosophy at a fraction of the wattage and price, aimed at single-GPU high-end builds rather than extreme multi-GPU rigs.
