Gospower 2400W SiC Titanium Server PSU Teardown: G1302-2400WND, 12.2V 195A, Dual STM32 Control
2026-10-08 · Compiled by Best IT Parts from public industry reporting
This teardown covers the Gospower G1302-2400WND, a 2400W server power supply with 80PLUS Titanium efficiency. It accepts 100-127V and 200-240V AC input plus a 240V DC input, delivering a 12.2V main output at 195A and a 12V/2.1A standby rail. The long metal chassis measures roughly 185 x 74 x 39.3 mm and weighs about 1033 g. The label rates 2400W maximum on 200-240V input and 1000W on 100-127V.
The topology pairs PFC with a half-bridge LLC stage and synchronous rectification, using CREE silicon-carbide switches. The PFC switch is a C3M0060065K SiC device rated 650V and 60 mΩ in TO-247-4, driven through an Si8261BBD-C isolated gate driver rated 4A and 5 kVrms isolation. The LLC stage uses SRC60R030FB MOSFETs rated 600V and 30 mΩ. The AC rectifier is a U30K80R bridge rated 30A/800V, and current sensing uses a 50A MCA1101-50-3 isolated sensor with 1.5 MHz bandwidth.
Control is built on two STMicroelectronics STM32F334R8T6 MCUs, one dedicated to PFC and one to LLC; each is a 72 MHz Cortex-M4 with 64KB flash and 12KB SRAM. Synchronous rectification uses ON Semiconductor NTMFS5C410NL MOSFETs rated 40V and 0.82 mΩ, driven by TI UCC27524A drivers. The standby supply is an On-Bright OB2362A controller with an 800V switch. Primary-side energy storage is a 450V/910µF capacitor, while the output is filtered by a 2700µF/16V polymer solid capacitor and a 1500µF/16V part, with an NTMFS4H01N 25V/0.7 mΩ FET for output control.
A 12V/3A fan with static blades draws air from the rear connector and exhausts it at the AC inlet. For buyers of server power supplies and spares, the design again shows the 2.4kW tier standardising on SiC PFC, half-bridge LLC and high-current synchronous rectification, with a dual-MCU control scheme reused across both power stages.
