It's not a well known brand and I'm not at home so I can't tell you the brand. I have a 1000W Platinum PSU from Corsair tho that I could use, I know it's overkill but is it bad that it has that much voltage?Some can and some can't. Which 500W PSU are we talking about?
Like Dark Lord of Tech said, the 1000w Corsair power supply is your best bet. 80+ platinum and a trusted brand is a lot better than a sketchy power supply. no matter you power supply wattage, your PSU only supplies what your PC needs... so again, use your Corsair power supply, as it will work better and has the least chance to pop.I just wanted to know if a 500w PSU could power an XFX RX580 8GB along with a Ryzen 5 3400G and a Gigabyte B450M-S2H
