1U 300W ATX Power Supply for Compact Servers

This 1U form-factor ATX power supply delivers 300W with a -5V rail, suited to rack-mount servers and space-constrained workstations. It matches the SPI3001UH, FSP250-50PLB and FSP300-601U part references for drop-in replacement. The unit arrives new and test-verified for immediate deployment.

Capacity and headroom: 300W with legacy -5V rail

The 300W rating covers typical single-CPU configurations with modest storage arrays and expansion cards. Systems demanding sustained loads above 300W or multiple high-power GPUs will exceed its headroom. Builds requiring only modern voltage rails without -5V support gain no advantage from this legacy output.

Questions about this item

Will the 1U form factor and ATX connector layout fit my existing rackmount chassis and motherboard?

This supply uses the standard ATX pin-out in a 1U height, so it matches the mounting holes and power connectors of any chassis and board designed for that combination.

How can I confirm the 300 W unit is delivering stable power after installation?

Power the system on and verify it completes POST and runs without unexpected shutdowns; a hardware monitor showing steady rail voltages under load confirms the supply is operating correctly.
