MPN #: TMPC-400-1U
Power outages or unstable electricity can halt critical medical equipment, risking data loss and patient safety. The TRUMPower TMPC-400-1U, 400W 1U Medical Grade ATX12V 80 Plus Gold PC Power Supply delivers reliable, clean power to compact 1U systems, ensuring continuous operation in hospitals, labs and mobile clinics. Its gold-level efficiency and full medical certification keep your devices safe and your energy bills low.
Unstable power is a hidden threat that can cause unexpected shutdowns during vital procedures, leading to costly downtime and potential safety incidents. This power supply eliminates that risk with a stable 400 W output, a wide 90-264 VAC input range and built-in overload, over-voltage and earth-leakage protection. The result is uninterrupted performance that meets strict medical standards, so you can focus on patient care rather than power worries.
The 400W Power Supply fits neatly into 1U rack-mount servers used for imaging devices, patient monitoring stations, laboratory analysis workstations, tele-health kiosks and compact AI inference boxes. Its universal voltage range lets you deploy it worldwide without extra converters, and its high-altitude rating makes it suitable for mountain clinics or airborne medical kits.
You gain stable power that prevents sudden shutdowns during critical tasks, gold-level efficiency that reduces electricity costs and cooling requirements, full medical certification that satisfies hospital procurement rules, a compact 1U form factor that frees up rack space, and global voltage compatibility that removes the need for additional adapters.

We are retiring PICOPC Products MNHO-073, MNHO-048 and MNHO-043 and they have reached EOL (End Of Life) as we are introducing new products with better technology. We would recommend you to look into MNHO-095. For Untangle, pfSense, OPNsense, Windows 11, Proxmox VE etc. we recommend MNHO-095 whereas for Sophos, Kerio Control and Endian, we would recommend MNHO-069. (A complete list of supported OS can be found in each product's listing)
