BGears b-Vigor550W 550W ATX power supply

What this power supply delivers

The BGears b-Vigor550W is a 550 W ATX unit with a compact 150 mm depth and a non-modular cable set. It accepts full-range AC input from 115 V to 230 V and meets over 80 % efficiency at 20 %, 50 % and 100 % load. Over-power and short-circuit protection are built in, and the product carries CE and RoHS markings. It suits builders who need a straightforward, fixed-cable supply for a mid-range system.

Who should consider a different unit

This model fits standard ATX cases that can accommodate a 150 mm deep PSU and works well for single-GPU builds with moderate power draw. Builders who prefer modular cabling for easier routing, or who need higher wattage for multi-GPU configurations, should look at other options. The non-modular design means every cable stays attached, which can limit flexibility in tight chassis layouts.

Installation notes and common issues

The 150 mm length helps it fit most mainstream cases, and the fixed cables eliminate the risk of loose modular connectors. Because all cables are permanently attached, cable management depends on case routing space and tie-down points. The main installation friction comes from stowing unused cables cleanly, especially in smaller enclosures where excess length has nowhere to go.
