yes i have apu, my psu is about 1 year nowYou were working with the APU from the get go? How old is the PSU stated in your thread's initial post?
it is brand new, can you recommend a affordable 650 watts psu?Regardless of the GPU being brand new or used, I'd advise on getting a 650W reliably built unit to power that entire system with an RX580 in it. As for your GPU purchase, is that brand new or used?
