ASRock Challenger CL-850G 850W 80+ Gold ATX PSU
The ASRock Challenger CL-850G 850W 80+ Gold ATX PSU is a non-modular ATX3.1 and PCIe 5.1 ready power supply aimed at value-conscious builders who want certified efficiency and modern connector support without overspending. It ships with a native 12V-2x6 connector for the latest graphics cards and an Auto iCool fan control system that adjusts cooling to load. A five-year warranty backs the unit for long-term use.
Why this product
80 PLUS Gold efficiency certification
Certified to meet 80 PLUS Gold standards, meaning less energy is lost as heat compared to lower-rated units, keeping running costs and internal temperatures down.
ATX3.1 and PCIe 5.1 ready
Compliant with the ATX3.1 specification and PCIe 5.1 standard, making it compatible with current-generation motherboards and graphics cards without needing an adapter.
Native 12V-2x6 connector included
Includes a factory-fitted 12V-2x6 cable rather than an adapter, reducing connection complexity and supporting the power delivery requirements of modern GPUs.
Auto iCool intelligent fan control
The 120mm golf-blade sleeve fan adjusts its speed automatically based on system load, running quietly at low loads and ramping up only when needed.
Classic Green connectors for easy seating
ASRock's colour-coded green connectors give a clear visual cue that each cable is fully and correctly seated before powering on.
Five-year warranty
ASRock provides a five-year warranty on this unit, which is above the typical three-year coverage found on many competing value-tier power supplies.

- Compatible with ATX form-factor cases that accept a standard ATX PSU (140mm × 150mm × 86mm).
- Works with ATX3.1-compliant motherboards and supports PCIe 5.1 power delivery via the native 12V-2x6 connector.
- Accepts wide-range AC input from 100 V to 240 V at 50/60 Hz, suitable for use in most countries.
- Provides two EPS 8-pin (4+4) CPU connectors, supporting both single and dual CPU-power motherboards.
- Non-modular design: all cables are permanently attached. Ensure your case has adequate space and cable management options before purchasing.
- Not suitable for SFX, TFX, Flex-ATX or any non-standard small-form-factor cases that require a compact PSU.
Best for
- Value-focused desktop builders who want 80 PLUS Gold efficiency and modern GPU connector support at a mid-range price point.
- Builders using current-generation graphics cards that require a 12V-2x6 connection, as the native cable is included rather than adapted.
- Users who prioritise long warranty coverage: the five-year term is longer than the three-year coverage common on many comparably priced units.
- Systems with moderate to high component counts drawing up to 850 W, including platforms with multiple storage drives and a discrete GPU.
Trade-offs
- Clean-build enthusiasts who prefer a tidy cable layout: all cables are permanently attached and unused ones must be managed inside the case.
- Small-form-factor builds: the standard ATX footprint (140mm × 150mm × 86mm) does not fit SFX or other compact enclosures.
- Workloads requiring more than 850 W: the rated output is 850 W and the unit is not designed for platforms that exceed this figure.
- Users needing more than four SATA ports: only four SATA connectors are provided, which may be limiting in high-drive-count storage builds.
