Is a 450W PSU good enough for a Ryzen 5 3600 + RX580 build?

those wattage sound a bit high https://www.tomshardware.com/reviews/amd-radeon-rx-580-review,5020-6.html

says there 225w is what the 580 will pull max.
i find it hard to believe that your A10-7860k is pushing it up to above 400w. even overclocked.
there's not alot of information about its wattage during actual use.
best i could find was a Guru3d post on the matter
says there it will pull a max of 83w

what else where you running cause those numbers don't add up lol

Peak power =/= Average power.

what is your point? those are max/peak power statistics.

I'm talking about the full system load.

It was an A10-7860K overclocked to 4.2 GHz, with 16GB RAM and the RX 580 8G from Sapphire, with an SSD and HDD.

well of course. i was aswel, i still don't feel you'd be hitting 400w,
that is why i asked you what else you have running.
cause 225w + 80w = 305w

the rest of your system was using 100w+ ? what? you must have had a million HDD's and like 50 PCIE cards then.

Again, TDP =/= Max power consumption. A stock RX 580 from Sapphire can use as much power as a 2080 TI.

AMD bases their TDP on heat, not power draw.

AMD page for it: https://www.amd.com/en/products/graphics/radeon-rx-580 They recommend 500W PSU minimum. I had a 500W PSU but it was old and lower quality SeaSonic and shut off because of that, on top of everything being overclocked.
Also RX 580 power draw: https://www.anandtech.com/show/11278/amd-radeon-rx-580-rx-570-review/16

No they aren't. You don't understand TDP, that's the problem.

what part do i not understand, you look at these charts and none of them are adding up to you initial statement, but whatever this is getting old at this point.



disregard my past statements apparently.

You're mistaking TDP for maximum power consumption. It's not, especially with AMD. AMD, Intel, and NVIDIA all have their own formulas for calculating TDP and they use it purely for marketing.

If you actually look at the graphs you can clearly see that the RX 580 is capable of pulling well over 300W.
