Power Supply DeepCool PN850M 850W 80 Plus Gold ATX 3.1, PCIe Gen 5.1 PSU

DeepCool PN850M is a 850W ATX power supply from a higher class, aimed at serious gaming and work configurations, including with modern GPUs according to the new standard. You have an 80+ Gold certification and up to 90% efficiency, which means less loss in heat and more stable power under load. It supports ATX 3.0/3.1 and PCIe Gen 5.0/5.1, so you are covered for modern and future graphics cards. The format is standard ATX with a compact length of 140 mm, which makes installation easier even in shorter cases.

What you get

With real 850W and modern DC lines 3.3/5/±12 V, you can easily run a powerful CPU and high-end GPU without worrying about stability. The built-in 16-pin PCIe 5.0 (12+4-Pin 12VHPWR) connector allows you to power the new graphics cards directly without adapters, and with another 3x 6/8-Pin PCIe, you have options for older generation cards or additional devices. The modular design means you only use the necessary cables – better cable management, better airflow, and less chaos in the case. The 120mm F.D.B. fan with a hydrodynamic bearing ensures quiet operation and long life, while the active PFC improves the power factor and stability under varying input voltage (100–240 VAC). Finally, the protections OPP/OVP/SCP/OTP/OCP/UVP/SIP/NLO protect not only the PSU but also your entire build in case of power or load issues.

• Power 850W – enough for strong gaming and workstation configurations with a powerful CPU and modern GPU.
• 80+ Gold certification and up to 90% efficiency – lower consumption, less heat, and more stable operation under load.
• ATX 3.0/3.1 and PCIe Gen 5.0/5.1 support – ready for the new generation of graphics cards and higher short peak loads.
• 1x 16-Pin PCIe 5.0 (12+4-Pin 12VHPWR) + 3x 6/8-Pin PCIe – flexibility for one powerful GPU or several lighter cards.
• 8x SATA and 2x IDE connectors – easy power for multiple SSDs, HDDs, fans, and other peripherals.
• Modular design – you only use the necessary cables for a cleaner build and better airflow in the case.
• 120mm F.D.B. fan – quieter operation and better reliability compared to standard sleeve or ball bearings.
• Compact dimensions 140 x 150 x 86 mm – easy installation in most ATX cases, including shorter models.
• Full package of protections (OPP/OVP/SCP/OTP/OCP/UVP/SIP/NLO) – system protection against overload, overvoltage, short circuit, and other anomalies.
• 120 months warranty – ten years of peace of mind for a key component in your PC.

For whom it is suitable

This power supply is a good choice for mid-range to high-end gaming builds and productive machines with current GPUs according to the PCIe Gen 5 standard. It is also suitable if you plan upgrades in the coming years and want a PSU that won't limit you. If you are aiming for an ultra-budget configuration with low-power hardware, this power and features may be too much for you.

The combination of 850W, 80+ Gold efficiency, ATX 3.1 / PCIe Gen 5 support, and a long 10-year warranty makes DeepCool PN850M a very sensible base for a serious and long-term build.
