PSU upgrade on P03-600

drpdrp

I have a p03-600 with stock PSU and want to upgrade to a 600 watt as I'm afraid of this PSU destroying my whole PC as I had a random shutdown a few weeks ago. I will also upgrade my GPU to maybe a 4060 in 2 years and it's a good investment. will the Be Quiet 600W System Power 9 be a good choice? It is an ATX power supply but the fan is pointing downwards rather than out of the case. Should I buy this power supply?

Oh yeah and does this have all the necessary cables? Sorry I am kind of new to this. Here is their product page: https://www.bequiet.com/en/powersupply/1279

What makes you think the shutdown was caused by the PSU? You can certainly install that 600W, but you likely don't need it until you do the GPU upgrade. Any of the ATX supplies should work in your case with your motherboard. The fan pointing down is just used so they can put a larger fan in than the typical one at the back. The air flow is in the same direction, but the larger fan can be run slower for the same CFM and that helps cut down on noise.

My pc never blue-screened. The power just cut all of a sudden. It hasn’t happened since but I’m really nervous it could break the whole machine.

First thing to verify is that the power cords are fully seated at both ends. If it's a little loose in the socket you can get a sudden power cycle. Are you plugged into a wall jack, a surge arrestor/power strip or a UPS? The only other thing I can think of that would give a sudden shut off like that is temperatures getting too high. Do you have a temperature monitoring app running? What's it showing for numbers?

My temps are fine, but I do have my pc plugged into a surge protector that also happens to power a space heater. The strange thing is my breakers for my house never reset which is what usually happens when I’m pulling too much power from a socket.

The surge protectors usually have a lower threshold than the breakers do. The SA is likely trying to keep brownouts from getting through, so just shut down when there's a drop or surge in AC voltage.

I was able to turn my PC back on right away afterwards which is why this is concerning. If this were at fault with the surge protector than I would need to turn it back on. No?

Only if the SA had a spike event. If it was just from a brownout it'd come back on itself, likely very quickly since they are usually short duration. Not to say the problem isn't a PSU issue, but before you start replacing parts it's best to try and understand what's really happening. Also, if the plan is to go to a '4060' in another year or two, better compare the power budgets needed between the 2060 and 3060. That 650W might be better set to handle things if it were an 850W instead...

I found an inexpensive be quiet ATX 700 watt power supply so I think I should be good to go with that one. Btw does the motherboard use a proprietary power connector? I’ve heard the Acer Nitro desktops have proprietary connectors.

There are several different models of the Nitro desktops. None have proprietary connectors, but some have connectors built to the newer standrs. The ATX12VO units have just 12V going to the board so they use two small connectors (8 pin and 6 pin), older ones have ATX power supplies and use the older 24 pin connector. Yours is the latter 24 pin type.
