MSI MAG A650BN 650W 80+ BRONZE

Main Specifications

Power Output

The MAG A650BN provides a 54A +12V rail rated at 648W, allowing the majority of the PSU’s available power to be delivered to the CPU and GPU. The +3.3V and +5V rails are rated at 20A each, with a combined output of 110W.

Connectors

The PSU comes with permanently attached cables and provides the following connectors:

• 1 × ATX 20+4-pin motherboard connector
• 1 × EPS 4+4-pin CPU power connector
• 2 × PCIe 6+2-pin graphics card connectors
• 5 × SATA 15-pin connectors
• 2 × Molex 4-pin peripheral connectors
• 1 × FDD 4-pin connector

Cooling and Design

The MAG A650BN uses a 120 mm low-noise fan with a sleeve bearing for cooling. MSI specifies a DC-to-DC circuit design, intended to improve output-voltage stability, together with an active PFC circuit for improved power efficiency.
