1200W Server PSU with Breakout Board

This 1200W server power supply carries part numbers 490594-001, 438203-001 and 498152-001 and matches the HSTNS-PL11 form factor. It ships with a breakout board and twelve PCIe 6-pin to 6+2-pin cables for multi-GPU configurations. The unit accepts 100 V at 10 A, 110-120 V at 10 A or 200-240 V at 7.8 A across 50-60 Hz mains. Builders needing redundant hot-swap frames or non-standard voltage rails cannot use this supply.

Installation and common issues

The breakout board plugs into the PSU edge connector and the twelve cables attach without soldering. Verify that your chassis can deliver the required input voltage range before powering on. A frequent problem is loose cable seating on the breakout header, which causes intermittent GPU detection. Another issue arises when the 200-240 V circuit is unavailable and the 10 A draw at 100-120 V trips undersized breakers.

Questions about this item

How do I verify the 1200W PSU is operating correctly after connecting the breakout board?

The power supply should spin its internal fan and deliver stable voltage across all 12 PCIe 6+2-pin cables when the server powers on and runs under load.

What components are included and what must be sourced separately?

The package contains one 1200W unit (490594-001 HSTNS-PL11), a breakout board, and 12 PCIe 6-pin to 6+2-pin cables; a mains power cord is not included.
