Power supply Asrock CL-850G 850W 80 Plus Gold ATX 3.1. PCIe 5.1 PSU

Asrock CL-850G is a 850W power supply from mid-range to high-end class, aimed at modern gaming and workstation configurations with more serious graphics cards. It supports ATX 3.0/3.1 and PCIe Gen 5.0/5.1, which means it is ready for the new generation of GPUs without unnecessary adapters. The 80+ Gold certification and declared 90% efficiency give you lower losses and less excess heat. The format is standard ATX with a length of only 140 mm, which helps with compatibility even with more compact cases.

What you get

With 850W real power and Active PFC, you have a stable power supply for strong CPU + GPU configurations, including graphics cards with the new PCIe 5.1 (12+4pin) connector. The cabling covers a standard gaming system with several drives and a powerful graphics card – 24-pin for the motherboard, two EPS 12V (4+4pin) for smoother power delivery to more power-hungry processors, and enough PCIe lanes for high-end GPUs. The 120mm F.D.B. fan takes care of cooling with lower noise and longer life compared to standard sleeve-bearing fans. The power supply operates in a wide input range of 100–240 VAC, so it is tolerant of variations in mains voltage. The fixed (non-modular) cabling may not be the most convenient for cable management, but it ensures fewer transitions and potential points of poor contact.

• Power 850W – sufficient for modern high-end GPUs and multi-core CPUs in one system without worrying about power shortages.
• 80+ Gold certification and 90% efficiency – less loss, lower electricity consumption, and less heat in the case under typical load.
• ATX 3.0/3.1 with PCIe Gen 5.0/5.1 – prepared for the new generation of graphics cards with direct PCIe 5.1 (12+4pin) connector.
• Rich set of connectors – 1x 24-pin, 2x EPS 12V (4+4pin), 4x PCIe (6+2pin), 1x PCIe 5.1 (12+4pin), 4x SATA and 2x 4-pin Peripheral, so you can power both a powerful GPU and several SSDs/HDDs and peripheral devices.
• 120mm F.D.B. fan – smoother operation and higher bearing durability, which reduces noise and the need for replacement.
• Compact ATX format – 140 x 150 x 86 mm – convenient for smaller cases and easier cable placement in the PSU tunnel.
• Active PFC and wide input 100–240 VAC – more stable power supply and better performance under unstable mains voltage.
• 60 months warranty – long-term coverage for a component that is critical to the entire system.

Who it is suitable for

This power supply is a good choice for gaming and creative configurations with modern graphics cards, including those with PCIe Gen 5 connectors, as well as for systems with a more serious CPU that requires two EPS 12V connectors. It is suitable if you want a balance between efficiency, power, and readiness for the next generation of GPUs without entering the extreme enthusiast class. If cable management and a clean internal look are your number one priority, the non-modular design may limit you a bit.

The combination of 850W, 80+ Gold efficiency, and support for ATX 3.1 / PCIe 5.1 makes Asrock CL-850G a stable foundation for your modern and future system upgrade. The most meaningful thing here is that you get current standards and a long 5-year warranty in a relatively compact ATX case.
