The AMD AM5 X670E model consumes more power when the operating system is in sleep mode.
The AMD AM5 X670E model consumes more power when the operating system is in sleep mode.
I've recently installed an AM5 system, the 7950X (not OCed) on an Asus ProArt X670E-Creator WiFi with a 4090 FE and Windows 11. My previous setup was an Intel i9-9900K (OCed) on an Asus ROG Maximus XI Hero with a 3080 FE and Windows 10. The power draw during sleep is around 11-12 watts on the new board, while my older Intel machine uses only a tenth of that. I suspect some new features on the motherboard could be increasing consumption, or perhaps a sleep state isn't enabled in UEFI. Still, 12 watts is quite high. All the same devices were transferred from the old PC to the new one, and I unplugged everything before sleep. Could it be that Windows 11 is using "Modern Standby" instead of the S1-S3 Hybrid Sleep state? Did I overlook a UEFI configuration? Or are these boards drawing more power even in sleep mode?
You're checking sleep power consumption? That makes sense. I'm a bit confused about the 9900K figure—did you forget it or was it an error? USB and RAM stay active during sleep, so 10-12 watts isn't that high for the processes happening. Just be cautious if you're worried about low wattage, though. USB passthru might also draw power even when off.
It relies on the device's sleep phase. S3 sleep would indeed provide realistic metrics. The PC in a low-power state always uses more power compared to S0, which keeps the system active. If it lacks support for S3 and only has S0, the best option is Hibernate. On NVMe storage, recovery typically takes around 5 seconds rather than instant. Perfectly accurate.
Turning off your PC doesn’t stop its peripherals from drawing power. The motherboard keeps its status lights lit even when powered down, and USB devices still supply energy. You can still charge your phone. To eliminate any power consumption, you’ll need to remove the power supply unit completely.
You should simply turn it off if you don't mind. If you're not sure, that's fine too. Does S3 block the USB ports or RAM? From what I remember, it's more of a configuration tweak rather than a fundamental change. Could you adjust S0 in the BIOS? Yes, modern systems tend to have more continuous features. Still, with a setup like 7950X + 4090 and the X670E board, power consumption is quite high—definitely not ideal.
For devices that aren't seeking a power handshake, yes. My am4 rig had the same issue. S0 was on with 11, which kept the case lights on. I turned it off easily, but my usual power use was around 2 watts. In 11 it spiked to 9 watts. I switched back and forth between S3 and 2w, but S0 only reached about 5 watts because it was more active. It shut down completely once, leaving only a small residual draw.
You're seeing 50 watts of power during sleep on your X570 system.
