A:AnswerMy PC was delivered with a Great Wall 80 Plus Gold E500 power supply. Don't expect to add much before you will need to upgrade the PW. I added a 4 TB WD hard drive and the system started having stability issues. Removing the drive solved the issues. So the PS is sized just about right for the system as sold.
A:AnswerIf you find out, let me know, I'm wondering also. Before June I plan on trying, but there is no documentation. I live where its always over 100 from May through Sep, it would be nice to AIO cooling and some front fans also
