MPN #: TMPC-400-1U
Power failures in medical and laboratory computers can jeopardise patient safety and data integrity. The TRUMPower TMPC-400-1U, 400W 1U Medical Grade ATX12V 80 Plus Gold PC Power Supply delivers a reliable 400 W output in a compact 1U form, providing clean, certified power for critical equipment so you can keep systems running without interruption.
This 400 W power supply fits neatly into rack-mount servers that drive imaging devices, patient monitors and lab workstations. Its wide 90-264 VAC input lets you deploy the same unit in hospitals worldwide, while the high-altitude rating supports remote clinics and mobile medical kits, ensuring continuous operation wherever it’s needed.
Choosing this power supply means you avoid the common pitfalls of overheating, wasted energy and non-compliant hardware. Its 80 Plus Gold rating guarantees at least 87 % efficiency at full load, which translates into lower heat output and a quieter environment-crucial in patient-care settings. The unit’s built-in overload, over-voltage and earth-leakage protections add an extra layer of safety, protecting both your equipment and the people who rely on it.
In addition, the TRUMPower design complies with IEC/EN/UL 60601-1 medical standards and carries approvals from UL, cUL, TUV, CB and CE. This means you can confidently meet regulatory requirements without extra testing, speeding up installation and reducing overall project costs.

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)
