Mystery Resistor?

[foxd01]

Hello folks, I'm trying to fix an ATX power supply, among other problems it has a blow resistor with markings that don't make sense to any of the calculators I've tried.
I'm reading it as red, red, silver, gold, green.
It is a large resistor (15.5mm) on the high voltage circuit.

Here is a huge picture - can anyone help me with the resistance and wattage values?
Thanks for any help.

Example: If the source voltage is 5V, and the resistance is 100Ω, what minimum power rating must the resistor have?
P = 5^2 / 100Ω = 0.25W = 1/4 watt.

The problem here is most online Resistor calculators explain everything , well , everything except how to draw a decimal . Maybe some when reading this will put a fix or something explanatory ..
Anyway , the general idea is , when you see 2 consecutive gold color , it means its x,x ohms , higher than zero . like for an example : Red , Red , Gold , Gold ==> 2.2 ohms . When you see 2 consecutive Silver Gold , it means 0.xx , example : Red , Red , Silver , Gold ==> 0.22 ohms . The remaining color , if there is , will be for tolerance .
