  • 80 PLUS Gold efficiency reduces waste heat
  • Full modular cables simplify dual-chamber routing
  • Detachable hub adds four USB ports and six fan headers

L-shape design for dual-chamber cases

The Lian Li EG1000G.BH is a 1000W ATX 3.1 power supply built around an L-shape connector layout that faces outward for clean routing in dual-chamber chassis. Its full-modular cable set and included fan hub module simplify builds that separate the power supply from the motherboard tray.

Upgrade from fixed-cable or standard ATX units

The jump is worth it when you move to a case that benefits from the reoriented connectors and need the 12V-2x6 cable for a modern GPU. Builders staying in traditional single-chamber layouts with older graphics cards will not gain the cable-management advantage this design provides.

1000W headroom for high-end single-GPU systems

The 80 PLUS Gold unit comfortably feeds a flagship graphics card and a high-core-count CPU together, with 2.5A available on the hub’s four USB ports for RGB controllers. Multi-GPU configurations or extreme overclocking loads that exceed 1000W will require a higher-capacity model.

Questions about this item

How much clearance does the L-shape design and 120 mm fan need in a dual-chamber case?

The L-shape orients connectors outward and the 120 mm fan draws air from the PSU chamber; allow standard ATX depth plus room for cables to bend cleanly toward the motherboard tray.

What is the correct order for attaching the detachable Edge Hub and its PCIe power cable?

Mount the hub, plug the supplied PCIe cable into the hub first, then connect the other end to the PSU’s peripheral port; reversing the sequence can leave the hub unpowered.

How often should the magnetic dust filter mesh be removed and cleaned?

Remove the mesh every few months, rinse with water, dry completely, and snap it back onto the integrated magnets to maintain airflow.
