1200W ATX 3.1 power supply

The BGears b-GoldX 1200W is an ATX 3.1 compliant unit rated for 1200W continuous output. It targets builders assembling high-end workstations or enthusiast gaming rigs that demand substantial 12V headroom. The semi-modular design uses black flat ribbon cables to simplify routing and improve internal airflow.

120mm fan and protection suite

A 120mm fan spinning at 2000 RPM handles cooling across the 115V to 230V input range. The unit carries 80+Gold equivalent efficiency at 20, 50 and 100 percent load. Protections include active power factor correction, over power, short circuit, over voltage, under voltage, surge and over current safeguards.

12VHPWR connector for modern GPUs

The native 16-pin 12VHPWR cable delivers up to 600W to a single graphics card, while four 6+2-pin PCIe connectors and five SATA plugs cover additional components. Builders upgrading from older ATX 2.x units gain PCIe 5.1 readiness without adapters. Systems that do not require a 12VHPWR connection or 1200W capacity will not benefit from the added cost.

Questions about this item

How do I install the 12VHPWR connector so the sense pins seat fully?

Push the 16-pin 12VHPWR plug straight into the GPU until the latch clicks; the four sense pins are shorter and will not engage if the connector is angled or stopped early.

Which component will likely need replacement first during long-term use?

The 120 mm fan rated at 2000 RPM is the only moving part; bearing wear over years of continuous operation is the typical replacement point.

What limit appears first when the unit runs at high load for extended periods?

The 1200 W maximum output is the hard ceiling; sustained draws above that trigger over-power protection and shut the supply down.
