Gamemax MAX P850B PSU ATX 3.1 850W 80 Bronze

Gamemax MAX P850B is an 850W ATX 3.1 power supply with 80+ Bronze certification, aimed at mid-range to more serious gaming and work configurations. You get a combination of sufficient power for modern GPUs and the current standard with support for PCIe 5.1. With efficiency up to 88% and Active PFC, the unit is designed for stable operation under normal load and the typical 200–240 V AC range in our country. The compact length of 140 mm makes installation easier even in smaller cases.

What you get

With a real 850 W output power, you have enough reserve for a classic combination of a powerful CPU and a strong GPU, plus several drives and additional fans. Thanks to the ATX12V v3.1 standard and 12V-2x6 600W PCIe 5.1 connector, you can directly power modern graphics cards without adapters, as the cables are sized for high peak loads. The four 6+2-pin PCIe connectors provide flexibility if you use previous generation GPUs or want to connect more than one card or additional expansion cards. With 4 SATA and 2 Molex (PATA), standard configurations with several SSDs/HDDs, fans, and peripherals are easily covered. A 120 mm fan takes care of cooling, and the 80+ Bronze efficiency means less energy loss and lower heat output compared to uncertified units.

• 850 W output power provides stable power for strong gaming and work configurations with modern GPUs and multi-core CPUs.
• ATX 3.1 standard and support for PCIe 5.1 via the 12V-2x6 600W connector prepare you for current and future graphics cards without the need for additional adapters.
• 80+ Bronze certification and efficiency up to 88% mean less loss as heat and more stable operation under typical load.
• Active PFC improves power quality and efficient use of energy from the grid in the range of 180–264 V AC.
• 1 x 20+4-pin ATX and 2 x 8-pin (4+4) EPS12V provide great compatibility and stable power for modern motherboards and processors.
• 4 x 6+2-pin PCIe, 4 x SATA and 2 x Molex (PATA) cover the mass needs for additional power for graphics cards, SSDs/HDDs, and peripherals.
• Compact ATX format with a length of 140 mm facilitates installation in shorter cases, and the black design fits unobtrusively into any build.

Who it is suitable for

This power supply is suitable if you are building a mid-range or more serious gaming/work computer with a modern graphics card and want to be covered for the PCIe 5.1 standard. It is also a good choice for upgrading an older build when switching to a more power-hungry GPU, but not if you are aiming for absolutely the highest levels of efficiency and silence from premium power supplies.

The most sensible aspect here is the combination of 850 W power, ATX 3.1 with a 12V-2x6 connector, and 80+ Bronze efficiency – a practical balance between current standards, stability, and price for a modern gaming build.
