Antec G850 850 Watt 80 Plus Gold SMPS

The Antec G850 is an 850-watt ATX power supply unit designed for mid-to-high-end desktop PC builds that demand stable, efficient power delivery. Carrying the 80 Plus Gold certification, the G850 is engineered to operate at or above 87% efficiency at 20% load, 90% efficiency at 50% load, and 87% efficiency at 100% load under typical 115V conditions — meaning less energy is wasted as heat during extended gaming or workstation sessions. The semi-modular cable design strikes a practical balance: fixed cables for the motherboard and CPU connectors ensure reliable contact at all times, while the remaining peripheral cables are detachable. This approach reduces unnecessary cable clutter inside your chassis, promotes better airflow, and simplifies cable management without the added cost of a fully modular platform. Antec's CircuitShield technology integrates a comprehensive suite of industrial-grade electrical protections into the G850. These include Over Current Protection (OCP), Under Voltage Protection (UVP), Over Voltage Protection (OVP), Over Power Protection (OPP), Short Circuit Protection (SCP), Over Temperature Protection (OTP), and No Load Operation (NLO) support. Together, these safeguards help shield your connected components from power irregularities and unexpected electrical events. The unit ships in a black finish and is backed by a 2-year manufacturer warranty from Antec. --- Verified Specifications --- Model: Antec G850 (SKU: G850-GB) Wattage: 850W Efficiency Certification: 80 Plus Gold Modular Type: Semi-Modular Color: Black Protections: OCP, UVP, OVP, OPP, SCP, OTP, NLO Warranty: 2 Years GTIN / EAN-UPC: 761345801609 Note: ATX standard version, connector count, fan size, and rail configuration are not confirmed in available source data and are excluded from this listing
