CORSAIR RM850e ATX 3.1 Low-Noise Power Supply with ThermalProtect 12V-2x6 Cable
An 850W fully modular ATX 3.1 power supply upgraded to Cybenetics Platinum efficiency and bundled with CORSAIR's ThermalProtect PCIe 5.1 600W 12V-2x6 cable, which monitors connector temperature and shuts off power at 65°C to help protect modern GPUs. Available in black and white.
AI score breakdown
scored as defaultThe biggest strength is its feature set for the class: ATX 3.1/PCIe 5.1 compliance plus a genuinely novel ThermalProtect 12V-2x6 cable with a 65°C over-temperature cutoff that directly addresses the connector-melting risk plaguing high-power GPUs, paired with quiet Zero-RPM operation and a compact 140mm chassis. The biggest weakness is that the RMe line remains a mainstream-tier platform—solid ±3% regulation and low ripple but not class-leading—so at a $139.99 MSRP it offers good rather than standout value against cheaper Gold-rated 850W competitors.
The overall score is the weighted average of these criteria — not a separate judgement. AI-generated scores are not hands-on test results. Percentages show each criterion's weight for this product type.
