[SOLVED] Used 5 month old CoolerMaster MasterWatt 750 in gaming system?

[AlexHoffman]

The seller told me he used it for 5 months. I did the paperclip test, and saw or heard nothing out of the ordinary. Now can I use it in my gaming system and what are the chances of it frying my components?

It is a mid range mediocre power supply.
If you are doing mid range build it will be OK. you will not be pushing it hard. R5 3600+ 2070 super, 10600+ 5600xt range.
If you are going high end I would not use it.

I have a ryzen 5 2600 and Vega 56, so I will be okay? Just hope it won't fry my components.

Short of taking it to a qualified person with proper testing equipment for analysis, there's an inherent risk installing any used power supply. With the exception of one or two models, Cooler Master is not known for making great power supplies to begin with. Proceed accordingly.

Maybe I should just buy a new one? Which one would you recommend? My systems wattage is around 400W.

System use for your PC is likely to be less than 400 watts the majority of the time. Any of these are acceptable:

Thanks!

All of those are available in 650 watt versions should you wish to have extra headroom for more powerful future upgrades, but a 550 will do the job for your current specs.

Coolermaster no exactly premium product
Acbel, Corsair, Enermax, and Antec
Those are real good ones
Even then check the qualify those with GOLD 80.
