ASRock PSU 850W ATX 3.1 PCIe 5.1 | Challenger Power Supply

The ASRock PSU 850W ATX 3.1 PCIe 5.1 90-UXC085-GNGAAA is a fully wired power supply for modern PC builds. It targets users building systems with next-generation graphics cards that require high power transients. The standout feature is native support for ATX 3.1 and PCIe 5.1 standards, specifically with a 12V-2×6 connector. This ensures stable power delivery for high-end components without messy adapters. It also carries 80 PLUS Gold certification for efficient operation.

Product Specifications

ATX 3.1 & PCIe 5.1 Compliance

This PSU is built to the latest ATX 3.1 and PCIe 5.1 specifications. It handles power excursions typical of modern GPUs. This means your system remains stable during sudden load spikes. However, you should confirm your case supports the standard ATX PSU dimensions, as these are not specified here. The native 12V-2×6 connector simplifies cable management significantly.

High-Efficiency Operation

The unit is 80 PLUS Gold certified. This indicates it converts AC power to DC power with minimal waste. In practice, this reduces heat output and lowers energy consumption over time. It helps keep your system cooler and quieter. The efficiency rating is a reliable metric for long-term running costs.

Smart Cooling & Noise Control

It features a 120mm golf-blade fan for cooling. The fan design aims to push air efficiently while maintaining low noise levels. Auto iCool intelligent fan control adjusts speed based on temperature. This balances acoustic performance with thermal management. For example, the fan may stop spinning under low loads on some units, though this is not explicitly confirmed for this model.

Native 12V-2×6 Connector

The ASRock Challenger includes a native 12V-2×6 connector with a dual-colour design. This connector is the updated standard for PCIe 5.1 graphics cards. It eliminates the need for bulky adapters, which can be a point of failure. So, you get a cleaner build and more direct power delivery. Always check the connector type matches your specific graphics card requirement.

Built-in 5V BOOST Function

This PSU includes a built-in 5V BOOST function. This feature can provide extra power to the 5V rail when needed. It helps maintain stable voltage for peripherals and system components during peak loads. This is a technical detail that supports overall system reliability. However, the exact trigger conditions for this function are not specified.

Box contents

Currently, the box contents are not explicitly listed. We advise confirming the included accessories with our team before purchase. Typically, a PSU box includes the unit itself, a power cable, and mounting screws.

Key points to check

• Confirm the physical dimensions fit your PC case (ATX form factor).
• Verify your graphics card uses a 12V-2×6 connector or is compatible.
• Check that your region’s mains voltage (UK 230V) is supported.
• Ensure the warranty is valid in the UK, as the country of origin is China.
