Cooler Master Elite Gold 850W Fully Modular PSU (MPX-8505-AFAG) — ATX 3.1 | PCIe Gen 5.1 | 80 Plus Gold ≥90% | 120mm Rifle Bearing Fan | 10-Year Warranty

The Cooler Master Elite Gold 850W is built for PC builders assembling mid-range to upper-mid gaming rigs around RTX 5070/5070 Ti, RTX 5080, RX 9070 XT, or similar current-generation GPUs paired with modern ATX 12V Ver. 3.1–compatible platforms — where 80 Plus Gold efficiency reduces operating costs and heat generation, ATX 3.1 with native PCIe Gen 5.1 16-pin support eliminates adapter concerns with modern GPU power connectors, and 10-year warranty coverage provides long-term build confidence at an accessible price point.

The 80 Plus Gold certification guarantees ≥90% power conversion efficiency at typical load — meaning less than 10% of drawn AC power is wasted as heat, reducing electricity consumption and lowering the thermal load on the PSU and surrounding case components during extended gaming sessions. ATX 12V Ver. 3.1 compliance with PCIe Gen 5.1 support and a native 1× 12+4-pin (16-pin, 650mm) connector accommodates the latest generation RTX 50-series and RX 9000-series GPUs that require the 16-pin PCIe Gen 5 power input directly — eliminating the need for any 8-to-16-pin adapter and the associated cable management and peak-load concerns. Three PCIe 6+2-pin connectors across two cables provide ample GPU power connections for dual-GPU or older single-GPU configurations. Stable full-rated 850W output is guaranteed at ambient temperatures up to 40°C — ensuring the PSU does not throttle or reduce output during India’s warm operating conditions or in closed case environments. The 120mm rifle bearing fan balances longevity (rifle bearings outlast sleeve bearings significantly) with low noise output — operating quietly during everyday desktop and moderate gaming loads. The fully modular cable design allows every cable to be detached and only the required cables installed — reducing clutter inside the case, improving airflow, and simplifying future upgrades or rebuilds. The compact 140mm depth fits in standard ATX cases as well as many compact mid-tower and smaller cases that struggle to fit 160mm+ PSUs. Five-way protection circuitry (UVP, OVP, OPP, OTP, SCP) guards all connected system components against under-voltage, over-voltage, over-power, over-temperature, and short-circuit faults during normal operation and fault events.
