Key Features
ATX 3.1 & PCIe 5.1 Ready with native dual-colour 12V-2x6
A native 12V-2x6 connector (up to 600 W) lets current high-end GPUs connect directly, with the updated, safer revision of the 16-pin standard and full ATX 3.1 power-excursion support.
80 PLUS Gold efficiency
Certified 80 PLUS Gold for high efficiency under typical loads, meaning less wasted energy, lower heat and reduced running cost.
Dual EPS for stable CPU power
Two 8-pin (4+4) EPS connectors deliver reliable power to demanding modern CPUs and motherboards — an advantage over single-EPS units in this class.
Auto iCOOL intelligent fan control
A 120 mm golf-blade fan with auto iCOOL control optimises cooling to the system load and stays quiet — running fan-stop at light loads for near-silent operation.
Compact 140 mm chassis
At just 140 mm long it fits easily into small-form-factor and space-constrained cases without compromising on 850 W ouTPUt.
Comprehensive protection + 5-year warranty
A full protection suite (OVP, UVP, OPP, OCP, SCP, OTP) and a 100,000-hour MTBF rating safeguard your components, backed by a 5-year warranty.

Frequently Asked Questions
Does the Challenger CL-850G support the latest RTX graphics cards?
Yes. It is ATX 3.1 / PCIe 5.1 ready and includes a native dual-colour 12V-2x6 cable rated up to 600 W, so current high-end GeForce RTX and Radeon cards connect directly.
Is this ATX 3.0 or ATX 3.1?
It is the newer ATX 3.1 standard and uses the updated 12V-2x6 connector (the safer revision of the 16-pin 12VHPWR), with full PCIe Gen5.1 readiness.
Is it modular?
No — the Challenger CL-850G is a non-modular (fixed-cable) unit. This keeps the price down while still providing all the connectors a typical gaming build needs.
Will it fit a compact case?
Yes. At 140 mm in length it is shorter than the typical ATX power supply, making it well suited to small and space-constrained builds.
What warranty does it carry?
ASRock backs the Challenger CL-850G with a 5-year warranty and a 100,000-hour MTBF rating.
Expert Insight
The Challenger CL-850G is ASRock’s value play for ATX 3.1: you get the native dual-colour 12V-2x6 connector and 80 PLUS Gold efficiency at a price well below premium modular units. The trade-off is fixed (non-modular) cabling, but the cable set is sensible for a single-GPU build and the dual EPS connectors are a welcome touch in this class. Its compact 140 mm body and auto-fanless iCOOL cooling make it a smart pick for small cases and quiet, everyday gaming systems. If you want detachable cables, 100% Japanese capacitors or a longer warranty, step up to ASRock’s fully modular Steel Legend range; if you simply want reliable, modern GPU-ready power at a keen price, the CL-850G delivers.
Buyer's Guide
Best for
Value mainstream & compact single-GPU gaming PCs needing native 12V-2x6 power.
Consider
Non-modular fixed cabling and a 5-year warranty — fine for value builds; choose modular for cleaner routing.
