The PSU definitely contributes to the pops and sparks because it handles high voltage. It's a budget model with no branding, which makes me skeptical. The label shows 700W total and up to 82.5W at +3.3V max, plus 125W at +5V max, 300W on each 12V rail—about 600W across the rails. That should cover an RX 580 if it uses one of those 300W outputs and the rest is on the other rail.
Not only from well-known companies, even Corsair has had some issues. I suggest looking at the PSU tier list here: https://cultists.network/140/psu-tier-list/ – it’s quite a lot to consider.
Sure, I’d choose a reliable power supply from a trusted manufacturer, preferably one with a connector designed for your existing outlets. Sockets lacking ground connections aren’t ideal by themselves.
Avoid using power supplies or voltage regulators on sockets without correct grounding. During a voltage surge or overvoltage event, these components can't safely direct excess current to the ground, leaving connected devices unprotected. This situation could damage or even cause fires and pose serious safety risks.
And that's the main electrical risk you need to address... Avoid using three-prong devices in two-prong sockets. The ground connection is crucial. Particularly with metal enclosures like power supplies, cases, and especially UPS units. Don't follow outdated advice about neutral prongs performing the same role. Hire a licensed electrician for correct wiring and installation. This is extremely dangerous.
