I recently upgraded to an RTX 5070, but my old 650W power supply that I've had for seven years doesn't seem to be cutting it anymore, as my PC restarts under full load. I'm considering two power supplies, both of which are ATX 3.1: the CX650M and the RM750e. My main priority is reliability. Which one do you think I should pick?

I'd recommend going for the RM750e! It's just more reliable overall, plus if you're in the US, it's widely available. You won’t regret it!
Generally, the 750W PSU is going to provide better performance. Just wondering, are you building this PC yourself or getting a custom-built one? If it's DIY, there are even better options out there if you're interested!
Don't overlook the importance of warranty! The RMe's is fantastic, but also consider factors like efficiency ratings and customer reviews if you're leaning towards quality.
The RMe model has a solid 7-year warranty, which is a great sign of its reliability. If you're open to it, the RMx offers a 10-year warranty, making it a reliable choice too!

Thanks for the tip! I'll definitely check it out.
