I chose the Corsair 650 Watts PSU because I read that the standard 1000W PSU can fry the PC. I hope it's enough for the 590W that it requires. For the cooling unit, I chose Cooler Master, not only because the upgrade was free. but also I read that the Cyberpower PC brand is an open ended liquid cooling system that requires maintenance. I hope that means that by choosing brand, I don't need to replace the coolant every time. Also, I hope that the cooling system is enough for the overclocking option that I chose (it's All Venom OC Certified). I hope I made the proper customization for the PC to last. Any thoughts?

 

I know. It's the quality of the product what concerned me, not the wattage. That's why I chose brand instead. Even if I chose a different wattage number for the standard PSU, there could still be chances for the PC to be fried anyway.

 

I'm keeping the one I already have. It's a Samsung that is still good enough for my PC and consoles until the day I also decide to upgrade the monitor.
