The fuses on this mainboard can be used several times (polyfuses). Shortly after the error state has
been eliminated, the fuses reset to the original state.
Mainboard current requirement
You require a Pentium4 power supply unit according to the BTX or ATX12V specification (BTX: 24-
pin + 4-pin connection; ATX12V: 20-pin + 4-pin connection) for this mainboard.
If you use an ATX power supply, a graphics card in the PCI Express x16 slot will only be supplied
with 25 W of power. For high-end graphics cards that require a power supply of up to 75 W, a BTX
power supply unit is required.
If you do not have a PC from Fujitsu Siemens Computer, make sure that the power supply unit
provides the required amperages.
