Montech BETA 2 650W power supply

ATX 3.1 Ready 650 W unit

The Montech BETA 2 650W is an ATX power supply rated at 650 W. It meets the ATX 3.1 Ready specification, supporting 200% total system peak wattage and 300% GPU power excursions. A single 120 mm fan handles cooling while 80 PLUS BRONZE certification guarantees at least 85% efficiency at typical load. DC-to-DC topology and a Japanese main capacitor provide tight voltage regulation and long-term reliability.

Mid-range builds with one graphics card

This unit suits builders assembling a system with a single GPU and standard storage counts. Two CPU 4+4-pin and two PCIe 6+2-pin connectors cover typical mid-range configurations. Four SATA and four Molex connectors support multiple drives and accessories. Builds requiring more than two PCIe power cables or higher continuous wattage should look at a larger model.

Two PCIe 6+2-pin connectors

The decisive specification is the pair of PCIe 6+2-pin cables. They limit the power supply to graphics cards that draw no more than two such connectors. If your chosen GPU needs three or more PCIe power inputs, this unit cannot support it.
