The workstation supports PCIe Gen2 (PCIe2) bus speeds and can support dual PCIe Gen2 graphics
cards in PCIe2 x16 slots.
When using the 475W power supply, the workstation supports:
A graphics card up to 150W in the primary graphics slot
A second graphics card in the second PCIe2 x16 slot (slot 4), provided the combined power
consumption of both cards does not exceed 150W
When using the optional 600W power supply, the workstation supports:
A graphics card up to 250W in the primary graphics slot
A second graphics card in the second PCIe2 x16 slot (slot 4), provided the combined power
consumption of both cards does not exceed 250W

Expansion card slots

The workstation implements one Intel X58 I/O chip to provide a total of six high-performance graphics
and I/O slots. In addition to the two full x16 PCIe Gen2 slots, two additional PCIe x8 (4) slots (x8
mechanically, x4 electrically) provide extra I/O bandwidth for high speed I/O cards. Open ended
PCIe x8 connectors let the user install x16 physical size cards in the x8 (4) slots.

Redundant array of independent disks (RAID) configurations for SATA support modes 0, 1, 5 and 10.
eSATA (3.0 Gbps) is supported using an optional adapter. The workstation provides 8 external and 4
internal USB 2.0 ports. The 475W power supply is 85% efficient and enables Energy Star Version 5.0
system configurations. HP WattSaver technology enables support of the European Union ERP Lot 6
power limit of 1W in off mode. HP Quiet Fan Technology enables quiet system operation. A plug-in
