The MONTECH BETA 2 850W ATX 3.1 power supply unit appeals to modern PC builders on a tight budget particularly with the ongoing DRAM and SSD price hike that’s pushing value in new PC builds further away.
Performance
Voltage regulation remains within specification across all rails, with tighter control observed on the PCIe outputs and expected droop on the shared EPS pigtail cable — behaviour that is consistent with its cable configuration rather than a sign of instability. The inclusion of a 105°C Japanese primary capacitor further reinforces its reliability credentials for a Bronze-class unit.
Value
Priced at an MSRP of US$69.90, the MONTECH BETA 2 850W sits on the more affordable end of the ATX 3.1 PSUs with native 12V-2x6 connectors. At this price point, it undercuts many competitors within the same efficiency tier while also providing a longer 5-year warranty. Beyond its electrical performance, the BETA 2 also distinguishes itself aesthetically, with embossed flat cables and MONTECH’s signature triangular vent design giving it a more refined look than typical budget-oriented power supplies.
Backed by a 105°C Japanese primary capacitor, embossed cables, MONTECH’s signature triangular styling, and a 5-year warranty, the MONTECH BETA 2 850W offers a well-balanced mix of reliability, modern GPU compatibility, and value without moving into higher-priced Gold-rated power supply unit options.
The MONTECH BETA 2 ATX 3.1 series power supply units are now available in the United States via the MONTECH Amazon Store, the 850W variant available for $69.90. Availability in the United Kingdom and EU to follow.
