Montech Power Supply 850W BETA 2 20+4 pin ATX ATX Black

Montech BETA 2 850W is an ATX power supply for modern gaming and workstation configurations, where you are already thinking about a more serious GPU and stability under load. With 850 W output power and 80 PLUS Bronze efficiency, it comfortably supports systems with a powerful CPU and high-end graphics card. The power supply comes with ATX 3.1 & PCIe 5.1 Ready design and native 12V-2x6 connector, so you are ready directly for NVIDIA RTX 50/40 series without adapters. The compact black case with a length of 140 mm makes it a convenient choice for tighter cases.

What you get

With real 850 W output power and Active PFC, you have stable power on all lines, which is most noticeable during prolonged gaming or rendering. The DC-to-DC architecture for the secondary lines improves voltage stability during sudden load changes – something critical for modern GPUs and CPUs that draw power in spikes. The Native 12V-2x6 PCIe connector allows you to connect an RTX 50/40 card directly, without dealing with adapters, additional heat points, and cable chaos. The HDB 120 mm fan is quieter and more durable than standard sleeve solutions, so under typical gaming load, the noise remains controllable. The Japanese main capacitor rated at 105 °C and the full protection package add peace of mind that in case of a problem in the network or components, the power supply will react in time.

• Power 850 W – sufficient for configurations with high-end GPU and many peripherals, without putting the power supply under constant 100% load.
• 80 PLUS Bronze efficiency (~85% typical) – less loss as heat and more stable operation during everyday gaming and prolonged load.
• ATX 3.1 & PCIe 5.1 Ready with native 12V-2x6 connector – direct support for modern NVIDIA RTX 50/40 cards, without adapters and unnecessary connections.
• DC-to-DC architecture – better stability on the 3.3 V and 5 V lines under dynamic loads, useful for SSDs, motherboards, and peripherals.
• Industrial Japanese main capacitor (105 °C) – higher durability over time, especially if the system often operates under load or in a warmer environment.
• Full protection package (OPP/OVP/UVP/SCP/OCP/OTP) – protection against overload, overvoltage, short circuit, and overheating for safer operation of the entire configuration.
• 120 mm HDB fan – lower noise and longer life compared to basic fans, suitable for cases with better acoustics.
• Advanced textured cables – easier cable management and cleaner build, even though the power supply is not modular.
• Compact dimensions 140 x 150 x 86 mm (ATX) – easier installation in smaller cases and more room for airflow at the front.
• Rich set of connectors – 1 x 24-pin ATX, 2 x 4+4-pin CPU, 4 x 6+2-pin PCIe, 1 x 16-pin 12V-2x6, 6 x SATA and 4 x Molex cover a typical modern system with enough drives and fans.

Who it is suitable for

This power supply is a logical choice for mid-range to high-end gaming configurations with plans for RTX 40/50 series, as well as for workstations with a more serious GPU. It is suitable if you are looking for a balance between price, efficiency, and current standard (ATX 3.1) without unnecessary RGB. If you are aiming for an ultra-quiet system under very low loads or platinum-class efficiency, you may want a higher-class PSU, but for a mass high-performance build, this is a very reasonable option.

The combination of 850 W power, ATX 3.1 + 12V-2x6 support, and DC-to-DC + full protections makes Montech BETA 2 850W a stable foundation for a modern build. This is a power supply that does not fall behind in standards and will withstand several generations of GPU and other hardware upgrades.
