Hi Everyone,

I bought this broken PSU from my friend there was 3 capacitors missing I have 2 capacitor but one is still missing because I don't know what type it is, my friend told me that it was ceramic capacitor green/grey but he lost it :-( Please see attached picture maybe someone can help me ???

Sorry for my English but it's my second language :-)

Are you sure it is a capacitor. The motherboard symbol in the position you have ringed shows it as a resistor not a capacitor.

Thank you for replay. Im not sure because I never did ths before and my friend he is not sure too. Do you know what type of resistor it could be?

My friend told me that the part was a circle and green / gray size about 1-2 cm

I found it its thermistor but Im not sure if it is ptc or ntc thermistor?

  Emil S 15:57 06 Apr 2018

Thanks yes it is NTC but what spec should I buy NTC 10D-11 10 ohm B 3A ?

I wonder why you are taking the trouble to fix a PSU which rated at only 200W. It is most likely not powerful enough to run anything reasonable.

Where on the circuit diagram is it located. My old eyes find it difficult to focus.

This is EVGA 850 GQ, 80+ GOLD computer PSU 850W. There is 3 part missing 1x PNP Transistor, 1x capacitor 270UF, 450V and one NTC Thermistor but I dont know what specs should the thermistor have. Im thinking to buy 10D-11 10 ohm B 3A but not sure

octal thank you for the information. I spot that too but forgot to write it :-) What will happen if I will use wrong one for example if it will be too high?ok? too low I think the answer will be blown thermistor

What will happen... Ouch dangerous to mess with a PSU if you don't know what you are doing. There are high voltages in a capacitor see click here
