0.12 Ohm, 5% fusible resistor. If it measures that then it is working, as they always fail higher value to open circuit. Resistors that are coated very rarely ( almost never and only those that are wire wound) fail by going low resistance, the coating tends to thin or the wire corrodes to make the resistance higher, never lower. The power devices associated with it are open circuit or dead short, probably along with the mains bridge and the fuse which will be open. If the supply is not running check for the standby 5V, it has to be there to get any thing out of the supply. Likely the little 8 pin standby power supply chip is very dead, or the small capacitors associated with it. Check the secondary side of the 5V SBY as well for bad capacitors and shorted diodes as well. Check as well the active PFC on the little heatshrunk board is working to generate about 300-400v on the main capacitor ( use care as any fault here will make it go bang)
