Hi,
I am going to mux power supplied to a PCIE card.
1. Main power supply : ATX power connector ,5.0A current limit
2. AUX power supply: PCIE connector,2.0A current limit(to comply with PCIE standard)
My Problem is,
1. Both the power supplies will be same 12V.Is it possible to use this in the given configuration?
2. Will the auto try feature of one efuse interupt the output supply by the other efuse?
3. When external power is not available output power should come from PCIE connector.My issue in that case main power efuse is not powered up. In a priority power configuration aux power is activated by PGOOD signal. Won't that be an issue?
