6 Best Alternatives to the Pstaroth 24 Pin ATX Power (2026)

Alternatives to the Jumper Bridge

MSI MAG 850W Fully Modular ATX Power Supply

The MSI MAG 850W replaces a simple diagnostic jumper with a complete, fully modular power supply. You get 850W of continuous power and ATX 3.1 compliance, which supports modern PCIe 5.1 graphics cards via a 12V-2x6 connector. This unit measures 8.75 by 4.92 by 12 inches, making it significantly larger than the tiny 2.36-inch jumper bridge. It carries a 10-year warranty and holds an 80 Plus Gold efficiency rating. You should choose this if you are building a gaming PC and need reliable power delivery rather than just a tool to test if a unit turns on. It is not a diagnostic accessory but a core component for your system.
