Hi everyone I have a dell optiplex 9020 SSF and I have moved everything into a thermaltake s100 tg case, im using the power button from the previous case and im getting a orange flashing light im about 70% sure its a PSU issue so im looking to upgrade it the size isn't an issue because of my new case i just dont know if there are any certain ones to get or ones you cant get i know I'll need a 24 to 8 pin adapter im running the standard CPU, 32gb of ram and a GTX 1650 low profile GPU on it i want a PSU that will be good for a while and for when I come to upgrade the motherboard in the future any help, advice or recommendations would be greatly appreciated
