ASRock Challenger 850W Power Supply - 80 PLUS Gold, Quiet

In this review of the ASRock Challenger 850W power supply the bottom line is straightforward: it is aimed at PC builders who need a reliable, efficient unit that stays quiet under load. Our review finds the CL-850G balances real-world value with useful modern features, most notably its 80 PLUS Gold efficiency and an Auto iCOOL intelligent fan that prioritizes low noise. It is a sensible choice for users upgrading to high-end GPUs or building long-lived desktops while wanting a five-year warranty as peace of mind.

Key Features

• 80 PLUS Gold Efficiency: High conversion efficiency reduces waste heat and helps lower operating costs while providing stable voltages to demanding components.
• Auto iCOOL Intelligent Fan Control: The fan automatically adjusts speed to keep noise minimal during light and moderate loads, improving day-to-day comfort.
• 120mm Golf Blade Fan: A larger, aerodynamically designed fan helps move air quietly and maintain stable temperatures under sustained load.
• 5 Years Warranty: A multi-year warranty offers confidence for longer-term builds and reduces worry about early failures.
• Compact ATX3.1 Form Factor: The unit's dimensions make it suitable for a wide range of mid-tower builds without consuming excessive internal space.
• PCIe5.1 12V-2x6 Cable Support: Includes modern GPU power connectivity to work with current and next-gen graphics cards.

Who It's For

The Challenger 850W suits PC builders upgrading to high-end graphics or those assembling systems that require stable, efficient power delivery without a lot of fan noise. Gamers and creators who value value for money and compatibility with modern GPUs will appreciate the mix of efficiency, warranty, and quiet cooling.

It is less appropriate for people who need fully modular cabling or extremely flexible custom sleeved cable layouts, since the non-modular design and some reports of stiff cables may hinder tight cable management. Users in unstable mains environments should also consider additional surge protection, as a small number of customers reported issues during brownouts.

Pros & Cons

Pros

• Reliable 80 PLUS Gold efficiency keeps operating temperatures and wasted energy down.
• Quiet operation thanks to the Auto iCOOL control and 120mm golf blade fan.
• Generous warranty period provides long-term support and confidence.
• Works with modern GPUs via PCIe5.1 12V-2x6 cabling according to customer feedback.

Cons

• Non-modular design and some reportedly stiff cables can make neat cable routing harder in compact cases.
• At least one customer reported a failure during a brownout, so additional protection is advisable in areas with unstable mains.
