150-W Add-In Module
The PCI Express x16 Graphics 150W-ATX Specification Revision 1.0 states:
• The slot connector provides main power to 75 W.
• A second cable-mounted add-in-module connector is used for an additional 12 V at 75 W.
• The 12-V main power at the slot and the 12-V additional power are separate.
• The hot plug functionality of PCI Express CEM1.1 is not supported.
In order to make it easier to use these 150-W modules in a hot swap environment, the 12-V 75-W source can be
operated from a TPS2490 power controller.
• Turn on the TPS2490 with the TPS2363 slot power controller.
• Wire-OR the Power Good outputs from each controller.
• On over-current or power failure of any supply, the slot power is turned off.
• If the 12Volt 75 Watt power is plugged into the module before it is inserted into the slot, all supplies to the
module can be powered at one time.
