Power Supply Unit Lian Li EG1200G 1200 W

The Lian Li EG1200G is a 1200 W SFX power supply unit designed for modern PC builds, especially dual-chamber or compact tower systems. It uses an L-shape form factor with outward-facing connectors to simplify cable routing, includes a removable magnetic dust filter for the top fan, and supports modular sleeved cables with extended length to reach components in various case layouts. The unit meets high efficiency standards with 80 PLUS Gold certification and integrates industrial-grade capacitors for reliable performance.

Advantages

The EG1200G combines an innovative L-shape design and a detachable EDGE hub (USB and 4-pin PWM fan hub) that can be powered directly by the PSU or independently via a PCIe 8-pin cable. A magnetic dust filter provides easy maintenance and improved airflow, while braided-texture sleeved cables and included cable combs help produce neat cable runs. Certification to 80 PLUS Gold and additional Cybenetics/PPLP levels ensures efficient power delivery and reduced heat output. The PSU also includes industrial-grade capacitors and comprehensive protection features (OCP, OVP, SCP, OPP, UVP, OTP, SIP, NLO and inrush current limiter) for stable, long-term operation.

Suitable for

• Dual-chamber cases (for example Lian Li O11 series)
• Compact tower builds requiring long modular cables
• Systems needing multiple case fans and RGB/USB controllers

How to use

Install the EG1200G in the secondary chamber of a dual-chamber case or in a compatible SFX/tower chassis following the case and PSU manuals. Connect the 24-pin ATX cable to the motherboard and attach CPU, PCIe and SATA modular cables as required. If using the EDGE hub, remove the protective cap and attach the hub to the PSU or connect it independently with a PCIe 8-pin cable to power the hub separately. Ensure the magnetic dust filter is placed correctly over the fan opening after installation.

Recommendations

For best results, route modular cables through the case’s dedicated channels to maintain airflow and a tidy appearance. Clean the magnetic mesh dust filter regularly and verify that fan and USB hub connections match your intended setup (fan PWM headers for fans, USB headers for RGB controllers or peripherals). Observe the PSU’s protection limits and ensure system power draw remains within the 1200 W rating.
