ASUS TUF Gaming 850W Gold EVO Fully Modular ATX 3.1 Power Supply

The ASUS TUF Gaming 850W Gold EVO is a fully modular ATX 3.1 power supply engineered for high-performance gaming PCs that demand stable, efficient, and durable power delivery. Built around ASUS's military-grade philosophy, every component has been selected and tested to outperform standard PSU designs across reliability, efficiency, and longevity. At the heart of the TUF Gaming 850W Gold EVO are TUF 5K black metallic capacitors, rated for a 52% wider temperature tolerance and up to 2.5 times the lifespan of standard capacitors. The PCB is shielded with a conformal coating that repels moisture, dust, and debris, guarding against short circuits in humid or dusty environments — ideal for tropical climates where humidity can reach 95% with salt fog exposure for up to 240 hours. Cooling is handled by a 135mm dual-ball bearing fan, which ASUS rates for up to twice the operational lifespan of sleeve bearing alternatives. This PSU does not include a 0dB fan mode, so the fan runs continuously at low speeds to maintain consistent thermals. The unit complies with the ATX 3.1 standard and supports PCIe Gen 5.1 graphics cards via an included 16-pin (12V-2x6) cable. It supports total power excursions up to twice the rated capacity and GPU power excursions up to three times the rated capacity, ensuring stability during transient GPU spikes from demanding graphics cards. Efficiency is dual-certified: 80 PLUS Gold at 115V and Cybenetics Platinum at 230V, meaning efficiency levels above 90% at typical loads. Acoustic performance earns a Cybenetics Lambda A- noise rating, with average noise output below 30 dB. Upgraded copper PCIe connector pins reduce connector temperatures by up to 12.28°C compared to standard connectors, a verified 29% reduction that supports demanding GPU workloads. Cables are premium embossed, UL1581 flame-rated and UL758-certified, operating at temperatures 50°C below the safety threshold during cable-managed routing. Protection circuits include OPP, OVP, UVP, SCP, OCP, and OTP for comprehensive system safeguarding. ASUS backs this unit with an 8-year warranty. — Verified Specifications — Wattage: 850W | Form Factor: ATX 3.1 | Modular: Fully Modular | Efficiency: 80 PLUS Gold (115V), Cybenetics Platinum (230V) | Noise: Cybenetics Lambda A- (120,000 hrs @ 40°C | PFC: Active | Connectors: 1× 24-pin MB, 2× 4+4-pin CPU, 1× 16-pin PCIe (12V-2x6), 3× 6+2-pin PCIe, 4× SATA, 2× Peripheral | Warranty: 8 Years | Hazardous Materials: RoHS compliant | AURA SYNC: No
