TFX 300 Be Quiet! 300W TFX PSU

High-Performance TFX Form Factor Power Supply Unit for compact chassis stability with the TFX 300

The TFX 300 is a 300W AC-DC TFX power supply engineered for space-constrained enterprise and embedded platforms where predictable power delivery and mechanical fit are primary design constraints. Designed to integrate cleanly into TFX chassis, the TFX 300 supports low-power CPU platforms with basic expansion by providing a stable DC rail foundation for motherboard VRMs, storage devices, and peripheral controllers.

In compact systems, airflow paths and cable routing are tightly coupled to uptime and serviceability; the TFX 300 is architected to maintain electrical stability under variable load while conforming to the TFX mechanical envelope to reduce integration risk. This makes it well aligned for appliance refresh cycles, OEM replacements, and entry compute nodes where PCIe add-in cards and storage backplanes must operate within conservative power and thermal budgets.

Why Choose the TFX 300?

The TFX 300 delivers a pragmatic density-to-reliability balance for TFX builds by pairing a compact PSU footprint with sufficient headroom for low-power compute and essential I/O. For IT teams standardising small form factor deployments, the TFX 300 supports repeatable integration, predictable platform behaviour, and straightforward field replacement without reworking the chassis power architecture.

Be Quiet! designs power solutions with a focus on electrically stable operation, controlled acoustics, and component selection aligned to continuous-duty expectations. The TFX 300 reflects this engineering approach, supporting modern data centre and edge standards where efficiency, thermal behaviour, and maintainability drive platform qualification.

Key Applications:

• TFX small form factor enterprise PCs
• Embedded and OEM appliance PSU replacement
• Entry-level compute nodes
• Compact edge gateways
• Low-power storage and utility systems
