Power supply DeepCool PN850-D PSU ATX 3.1 850W 80 Plus Gold

DeepCool PN850-D is an ATX power supply with 850W power and 80+ Gold certification, aimed at mid-range to high-end gaming and work configurations. With support for ATX 3.0/3.1 - PCIe Gen 5.0/5.1, you are ready for modern GPUs without the need for adapters and compromises. Efficiency up to 90% helps keep consumption and heating under control, especially under heavier load. Combined with active PFC and quality protections, this is a stable foundation for a serious build.

What you get

With 850W real power and a DC 3.3/5/±12 V line, you have enough capacity for a powerful CPU and modern GPU, plus multiple drives and fans. The PCI-E 5.1 connector with high-quality 105°C-resistant 16AWG copper-core sleeved 12V-2x6 cable (600W) allows you to power a modern graphics card through one cable without worrying about stability. The rich set of PCI-Express 6+2 pin, SATA, and Molex connectors covers everything – from high-speed SSDs to older peripheral hardware. 80+ Gold and Cybenetics Gold ratings mean less loss as heat, more stable voltages, and quieter operation in the long term. A 120mm fan in an ATX format case and active PFC help ensure reliable and relatively quiet operation under normal to high pressure.

• Power 850W – sufficient for a strong gaming or work build with a powerful GPU and plenty of storage.
• 80+ Gold and efficiency 90% – lower consumption from the grid, less heating, and a more stable system under prolonged load.
• ATX 3.0/3.1 - PCIe Gen 5.0/5.1 – native support for the new PSU generation and direct powering of modern graphics cards.
• PCI-E 5.1 x 1 with 12V-2x6 cable (600W) – high-quality, 105°C-resistant 16AWG sleeved cable optimized for powerful GPUs.
• 3x PCI-Express 6+2 pin, 8x SATA, 2x Molex – flexible cabling for a combination of modern SSD/HDD and older hardware.
• 120mm fan – provides cooling for components in a standard ATX case without excessive noise.
• Multiple protections: OPP, OVP, SCP, OTP, OCP, UVP, NLO, SIP – cover the main risks (overload, overvoltage, short circuit, overheating, etc.) and protect your other hardware.
• Rated Gold by Cybenetics – additional independent assessment for real efficiency and behavior in various modes.

Who it is suitable for

PN850-D is a good choice if you are building a serious gaming or productivity build with a modern graphics card and want a power supply ready for PCIe Gen 5.0/5.1 standards. It is also suitable for those planning an upgrade to a more powerful GPU in the future and do not want to change the PSU due to new connectors. If you are aiming for ultra-compact systems or absolute high-end beyond this power class, you may find it either too large in format or insufficient in headroom.

The combination of 850W power, 80+ Gold efficiency, ATX 3.0/3.1 support, and native PCI-E 5.1 connector makes DeepCool PN850-D a balanced and relevant choice for a serious yet sensibly sized build.
