Murata Power Solutions announces D1U74T common redundant power supply

Murata Power Solutions has announced the D1U74T series designed to meet the CRPS (Common Redundant Power Supply) standard defined by Intel® and target server products for supercomputers, high-performance computing (HPC) systems, artificial intelligence (AI), machine learning, and crypto mining applications incorporating GPUs / ASIC topologies. The D1U74T provides 12VDC at 2700W output power and is approved to Titanium efficiency levels beyond 96% at half load offering the highest power density CRPS approved power supply on the market.

Additional features include 12VDC always-on standby voltage, active current sharing, a multi-function status LED, variable fan speed, and PMBus™ 1.2 digital communications capability. The D1U74T features ultra-high-power density of 82W/cubic inches and is ideal for delivering reliable and efficient power to servers, networking equipment, and storage systems. Optional accessories include the D1U74T-BRB (breakout board) interface card kit which can be used for evaluation and powering crypto-mining applications. The kit comprises of 18 x 6pin PCIE connectors and 10 cable assemblies.
