Power Supply Unit Lian Li EG1200G 1200 W

The Lian Li EG1200G is a 1200 W power supply unit in a compact SFX form factor designed for modern PC builds, particularly dual‑chamber and tower chassis. It features an L‑shape layout that reorients connectors outward for simplified cable routing, a detachable modular USB and fan PWM hub (EDGE Hub), a removable magnetic dust filter, braided sleeved cables, and industrial‑grade capacitors. Certified 80 PLUS Gold and supporting ATX 3.0/3.1, the unit delivers efficient and stable power for high‑performance systems while maintaining effective cooling with a 120 mm PWM fan.

Advantages

The EG1200G’s L‑shape design and longer modular cables facilitate neat cable management in dual‑chamber or regular tower cases and make vertical installation more accessible. The removable EDGE Hub provides six 4‑pin PWM fan connectors and four USB ports (supporting up to 8 downstream devices) that can be powered directly from the PSU or independently via a PCIe 8‑pin cable. A magnetic mesh dust filter with high porosity enables good airflow and easy cleaning, while braided‑texture sleeved cables with cable combs ensure tidy runs. German EPCOS (or equivalent Japanese) capacitors and a robust 12V‑2×6 dual‑color PCIe connector increase reliability and long‑term stability. Multiple protection circuits (OCP, OVP, SCP, OPP, UVP, OTP, SIP, NLO) and an inrush current limiter safeguard components and system operation.

Suitable for

• High‑performance gaming PCs and workstations requiring 1200 W of power
• Dual‑chamber cases (for example LIAN LI O11 series) with vertical PSU installation
• Systems with multiple fans and RGB/USB peripherals that need expanded USB and PWM fan connections

How to use

Install the EG1200G in the designated PSU chamber according to your chassis manual, aligning the L‑shape orientation for outward connector access if using a dual‑chamber case. Connect the 24‑pin ATX main cable to the motherboard and attach CPU and PCIe power cables as required by your components. If additional fan or USB connectivity is needed, attach the EDGE Hub to the PSU or connect it independently using a PCIe 8‑pin cable. Remove the magnetic dust filter for cleaning as part of routine maintenance and reattach when finished. Follow standard safety precautions: power off and unplug the system before connecting or disconnecting cables.

Recommendations

Use the longer modular cables and cable combs to route power leads through the second chamber or behind the motherboard tray for a clean build. For systems with many fans or RGB controllers, power the EDGE Hub directly from the PSU for centralized management, or use the PCIe 8‑pin option when independent hub operation is required. Regularly clean the magnetic dust filter to maintain airflow and cooling efficiency.
