Upgrade AMD Bulldozer to Cezanne

I upgraded my desktop computer from AMD Bulldozer FX 8120 to AMD Cezanne 5700G. I also upgraded from a hard drive to M.2 SSD storage, upgraded from 16 GB DDR3 to 64 GB DDR4, upgraded from 21″ to 32″ 4K monitor. I bought the hardware from Mindfactory.

The parts and its assembly on the motherboard.

Mounting into Chieftec case and cabling.

It was quite helpful that the RAM modules are illuminated. At first I was hesitant to press firmly the modules onto the motherboard. But using force when pressing was necessary.

The "old" motherboard with Bulldozer and Alpenföhn cooler except first image in gallery.

Observed power consumption is now roughly 30 W when machine is mostly idle. The old Bulldozer machine did need at least 40-60 W when idle. See Plotting Power Consumption of my Desktop PC.

See also ASRock DeskMini A300M with AMD Ryzen 3400G. There I described the setup for the machine for the living room, which had separate requirements for power consumption and quieteness.
