ASUS ROG STRIX 850W 850P-GAMING-E 20+4 pin ATX ATX Black Power Supply

ASUS ROG STRIX 850P GAMING-E is a high-end 850W ATX power supply designed for powerful gaming and enthusiast configurations. With 80 PLUS Platinum efficiency and active PFC, it is aimed at stable operation under serious load and lower energy consumption. You get ATX 3.1 / PCIe 5.1 compatibility and a 12V-2x6 (12+4 pin) connector for modern high-end GPUs. The modular design, 135 mm fan with 0dB technology, and RGB lighting make it both a practical and visually complete component for a serious build.

What you get

With a real 850 W output power on a single +12 V rail (70.8 A), you have a stable reserve for powerful CPUs and GPUs without the risk of shortage under load. The 80 PLUS Platinum certification means high efficiency, less heat loss, and lower load on the electrical grid, especially during long gaming sessions or rendering. The ROG Equalizer 12V-2x6 PCIe cable with GPU-First Intelligent Voltage Stabilizer is aimed at more stable power delivery to the graphics card during sudden peaks. ROG coolers and a 135 mm fan with dual ball bearing and 0dB technology give you lower temperatures and less noise under light loads, with a Cybenetics noise rating of A. The fully modular design and physical power switch on the back panel make assembly, maintenance, and system management easier.

• 850 W output power with maximum load on +12 V of 850 W (70.8 A), sufficient for a high-end gaming build with a powerful graphics card and plenty of peripherals.
• 80 PLUS Platinum efficiency for less heat loss, lower consumption, and more stable operation under prolonged load.
• ATX 3.1 and ATX12V 3.1 standard with PCIe 5.1 support and 1x 12V-2x6 (12+4 pin) connector, ready for the latest generations of GPUs.
• ROG Equalizer 12V-2x6 with GPU-First Intelligent Voltage Stabilizer for more stable voltage to the graphics card during peak loads.
• 135 mm fan with dual ball bearing, active cooling, and 0dB technology for quiet operation under low and medium loads.
• Complete set of protections – OPP, OVP, UVP, SCP, OCP, OTP, plus MTBF over 120,000 hours @ 25°C for long lifespan.
• Fully modular design with modular cable management, black chassis, and AURA Sync compatible RGB lighting for a clean interior look and synchronized build.
• Wide input voltage 100–240 V and RoHS compliance, suitable for long-term use in various electrical environments.
• Compact dimensions 160 x 150 x 86 mm and weight 1.78 kg, convenient for most ATX cases.

Who it is suitable for

This power supply is for gamers and enthusiasts who plan a strong or upgradeable build with a modern PCIe 5.x graphics card and want stability, high efficiency, and a good noise profile. It is also suitable for working with heavy applications – 3D rendering, streaming, productivity. If you are building an ultra-budget system or a small ITX build with limited space, the 850W Platinum ATX PSU may be more of an unnecessary luxury.

The combination of 850 W power, 80 PLUS Platinum efficiency, ATX 3.1 / PCIe 5.1 support, and quiet operation with 0dB mode makes the ASUS ROG STRIX 850P GAMING-E a very solid foundation for a serious and future-oriented gaming or work computer.
