550 W ATX 3.1-ready PSU
The Montech BETA 2 550W is an ATX power supply rated for 550 W continuous output. It meets the ATX 3.1 specification and can handle 200 % total system peak wattage plus 300 % GPU power excursions. A single 120 mm fan provides cooling while the unit carries 80 PLUS Bronze certification for over 85 % typical-load efficiency.
Builders needing two CPU and two GPU connectors
This unit suits systems that require one 20+4-pin motherboard connector, two 4+4-pin CPU connectors and two 6+2-pin PCIe connectors. It also supplies four SATA and four Molex 4-pin leads. Builds that demand more than two PCIe power cables or a higher continuous wattage rating should look at a larger model.
Case depth and cable routing before ordering
The housing measures 140 x 150 x 86 mm, so confirm that your chassis can accommodate that length and width. Check that the fixed cable set reaches all component positions without strain. Verify that your motherboard uses a standard 20+4-pin socket and that the two 4+4-pin CPU headers match your board layout.

Questions about this item
Does my motherboard need a 20+4 pin ATX socket and two 4+4 pin CPU sockets to use this 550 W unit?
Yes, the PSU includes one 20+4 pin motherboard connector and two 4+4 pin CPU connectors, so your board must provide matching sockets.
Can I keep an older graphics card that only needs a single 6-pin power connector with this supply?
The unit ships with two 6+2 pin PCIe cables; each can serve a 6-pin plug by leaving the extra 2 pins unused.
How can I verify the PSU is delivering stable power after installation?
The built-in OPP, OVP, UVP, OCP, OTP and SCP protections will shut the unit down if voltages drift out of spec, so a successful boot and sustained load confirm correct operation.
