I recently bought an Ender 3 3d Printer that comes with a cheap Chinese 24V 15A PSU. Unfortunately, the PSU went dead and by inspecting the board, I found out that two resistors were fried (both the same value). By looking at the resistor’s code bars, I see that the first band is colored black.
The bands read: BLACK, YELLOW, VIOLET, SILVER and BROWN. (Please see the picture below).
It appears that the last band is brown as it looks like is the one most separated from the others. I would appreciate if anyone can give me any hints on where or what resistors to get.
I already replaced the cheap PSU for a Mean Well. However just for the fun of it, I want to repair the dead one.

You can use a resistor calculator to get the value of the resistor:
This is a .47 ohm, 1% resistor. From the size of it, I'd say that this is a 1/2 watt (or possibly 1 watt) resistor, that will be the challenge to determine the wattage rating. You can order them from the site with the resistor calculator linked above, or just about any other site, just type it into Google.
