Slots one, three, five, and six use open-ended PCIe connectors, so a PCIe x16 card can be inserted. This allows the workstation to support more PCIe x16 expansion cards. A x16 card typically trains and runs at the maximum lane width available by the expansion slot. The card runs at the reduced lane width, with a corresponding performance decrease. A x16 graphics card runs at the bandwidth of the slot it is plugged into. The slot bandwidth can be x1, x4, x8, or x16. A PCIe card can be plugged into a slot with a lesser speed. It runs at that speed with a commensurate performance decrease. (Older graphics cards may not comply with this.) Expansion card configuration restrictions for power supplies CAUTION: To prevent damage, the overall power consumption of the workstation (including I/O cards, CPU, and memory) must not exceed the maximum rating of the workstation power supply. For power supply information, see Power supply specificationson page 11. The maximum graphics card configuration is: Power supply 650W Graphics card maximum 75W One in slot #2 and One in slot #4 150W One in slot #2 or One in slot #4 Graphics cards greater than 75 watts require the use of an auxiliary power cable adapter. If a graphics card greater than 75 watts is used, HP recommends that you leave the adjacent slot empty, and follow any additional workstation configuration restrictions. You can also use a lower power or lower profile card between slots for optimum cooling. See the Site preparation guide for the HP 600 Workstation at http://hp.com/support/ workstation_manuals for further power consumption information. ENWW Removing and installing components 131
