Antec Neo HE550 Power Supply - Burnt Green Ceramic Capacitor: Seeking Exact Parameters for Repair

Hello,
One day, by switching on the power something shot in the power supply and the computer did not start. After unplugging the power supply I noticed that the element marked on the picture is damaged. I would like to repair it and solder a new element, in fact it is a ceramic capacitor in green color if it is well-oriented. I do not know what parameters the element has because it is so damaged that nothing can be read from it. I have a request for people who have or repaired such a power supply and could write to me the exact parameters of this capacitor.
greetings

It is true that I did not deal with this particular power supply, but judging by the photo and the length of the ends it is rather:
- thermistor (in series with power supply) or
- varistor (parallel with power supply)
conclusions you need to draw after analyzing inclusion in the system.
Are there other components damaged?

After browsing the whole plate, you can not see that there is any other item damaged except in the picture. The burned element combines one lamp with a diode and I think it is a varistor after reading about it on the wiki. I will add with recently had variations with voltage and it exceeded 250V so it would suit the varistor. To solder it, I need to know what parameters it has or just buy it in green because I do not know it completely but I can solder

If only the varistor has been damaged, then after removing it and replacing the fuse, the power supply should work.
Because you wrote that the voltage in the network was up to 250 v, working without this protection may involve more damage.
As for the choice of parameters it depends on whether it is switched on before the rectifier bridge from the network side - AC, or after it, after straightening - DC.
In the first case Uvar ? 250VAC, in the second Uvar ? 350VDC.
First of all, however, you should take care of a stable network, because with a varistor with a low operating voltage installed, the situation will be repeated, and if it is too high, it will not protect the power supply.

Hey.
I have the same problem with the same power supply. In my power supply, the same element has been damaged. Unfortunately, its markings can not be read.
On the plate it is described as TR301.
I've searched the network a bit and once it is recognized as a varistor and once as a thermistor.
Can you specify what is it and what to look for in the exchange?
