Hello everyone, I pulled this blown fuse out of the high side off a computer power supply, im not able to find a replacement online by searching for the markings on the fuse; that read 250V 5G 12A.I know the 12A means 12 amp, and that it is a fuse designed to be used with AC current (to prevent arcing when blown), with a maximum voltage of 250V. However im not so sure about the 5G. The fuse can be seen in this image. If anyone can help me learn what type of fuse it is, it will be very much appreciated. Adding some more info: The Power Supply is a 650 watt. According to ohms law when it comes to calculating a fuse rating, we do 650 watts Divided by 240 (For New Zealand AC power). This gives me a rounded rating of 3 amps. I am definitely missing something here.
P.S. Before inserting a new fuse I would check that there are no faults in the PSU. From the splatter inside the fuse it would suggest that there is a severe fault in the power supply, possibly a shorted MOSFET or diode.
depends if it was a slow or fast blow
