Patent ID: 7990157

Claim:
A card for simulating peripheral component interconnect (PCI) loads of a computer motherboard, comprising: a PCI interface operable to be inserted into a PCI slot of the computer motherboard, and comprising a first to a third voltage receiving pins to receive a first to a third voltage signals, respectively, from the computer; and a first load module, comprising: at least one first load resistor; at least one second load resistor; a first electrical switch, wherein a first terminal of the first electrical switch is connected to the first voltage receiving pin of the PCI interface, a control terminal of the first electrical switch is connected to the third voltage receiving pin of the PCI interface via a first divider resistor, a second terminal of the first electrical switch is grounded via the at least one first load resistor, the first electrical switch is turned on in response to the control terminal of the first electrical switch being at a high voltage status; and a second electrical switch, wherein a first terminal of the second electrical switch is connected to the second voltage receiving pin of the PCI interface, a control terminal of the second electrical switch is connected to the third voltage receiving pin of the PCI interface via a second divider resistor, a second terminal of the second electrical switch is grounded via the at least one second load resistor, the second electrical switch is turned on in response to the control terminal of the second electrical switch being at a high voltage status.
