Would a 430W PSU be enough for an RX 580?

Just wondering if my PSU is enough because I am looking to upgrade to a GPU.

Here are my specs

CPU: Ryzen 5 2400g(Stock Cooler)
Motherboard: B450 I Aorus Pro WiFi
RAM: Ballistix 2x8 3000MHz
SSD: Samsung 860 500 GB
PSU: Thermaltake 430W Smart Series

Not sure if this helps but will also list peripherals

Mouse: Logitech G502
Keyboard: Logitech G213
Headphones: G430
(yes I know, I'm bit of a Logitech fanboy)

I have an undervolted RX480 running at 1305MHz (slightly below RX580 stock frequency) that draws 100W in Furmark. I'd say, if you also undervolted your GPU and didn't overclock your CPU, you could be looking at a total system power draw of....250W. If you have an factory OC'd card that you run stock, that could creep up to 300W. If you had a good quality 450W 80+ Gold efficiency PSU and know what you're doing, I'd say that's enough. However, pretty much anybody will be comfortable on a decent 550W 80+ Bronze unit which probably costs the same.

Your PSU can only supply 410W max. It's also not even 80+ Bronze efficiency. I also don't trust Thermaltake PSUs at all.

Yes but better as in more watts or better efficiency?
