Today i turned on my pc and during boot there was a loud gunshot sound along with the smell similar to a cap gun. I assume it was the PSU as the computer restarted and was booting into windows but I turned it off to be safe. The motherboard and graphics card both look fine too.
Just to be sure this was likely the power supply right? Any idea what caused the bang and is it safe to keep using or risky?
Under the assumption it will need to be replaced, ive been browsing replacement units. Three that caught my eye that are available in store in my area are the Corsair RM650X, Corsair RM850X(2018rev) and the Evga Supernova 650 G1+. The corsair rmx line is recommended but evga seems super popular right now and it can be had for $60 less however there seems to be little info on this new model. The corsairs both cost roughly the same as each other with price matching.
My computer is dated (3770k, 670gtx, ssd/hdd etc) but I plan to build a modern equivalent within the next year. I build around silence in mind.
Any idea if the Evga is any good and worth the cost savings?
If I go corsair, is there any benefit or negative to going with the higher wattage/newer revision? While being a newer it seems overkill. Been a long time since I bought a psu so any help is greatly appreciated.
