So.... with the energy crisis in Europe I became curious about the power consumption of a next gen Amiga.... I have ordered a meter for it, but it will not arrive until mid next week.
My machine has the following hardware.... AX5000 Motherboard (020)
Radeon RX550 GFX board (PCIe) HD compatible Audioboard (PCIe) 100 MBit Ethernet card (PCI) 4x SATA expansion (PCI)
1x DVD Reader/Burner (internal SATA) 1x 2TB 3.5" Harddrive (internal SATA) 1x 2TB 3.5" Harddrive (connected to the PCI SATA card)
How much does your next gen Amiga draw in idle mode as well as power mode? Power mode would be when you for example play a demanding game such as Jedi Outcast, Jedi Academy or Doom 3.
Prefs/Powersettings did not change any power consumption for regular 2D usage of programs such as Odyssey or Rave. So I left it to HIGH setting to make sure the games that uses GPU performs as good as they can. The numbers below are the peaks I could see on the meter.
Stand by (computer turned off, PSU turned on to give some power to motherboard): 0.9W
Idle with WB booted: 70.7W Quake 1 CPU Rendering 800x600: 70.7W Rave encoding to MP3, VBR Quality 5 (1h 47m stereo wav-file) Encoding time: 9m 14s: 70.7W
Onto some CPU & GPU usage then...
Jedi Outcast GL4es, 800x600: 80.0W Return to Castle Wolfenstein GL4es, 1920x1080: 86.6W
What surprised me most is that there is no difference in power consumption when stressing the CPU. Another thing to add is that the CPU stayed at a stable 60 Celsius. But this puzzles me a bit... any idea of why stressing the CPU doesn't draw more power?
I also wonder why my idle power consumption is so much higher compared to some of the other tests in this thread? My guess is the 2x mechanical SATA harddrives. Any thoughts on that?
