The ASUS ROG Crosshair VIII Dark Hero is one of the highest quality and most expensive AMD X570 motherboards available. This is especially true if you ignore the very extreme models at the top end, which seem to have little practical use in everyday life.
This makes it all the more annoying that this model appears to have a hardware defect, at least according to rumors. Several threads in the official ASUS forums have been closed or removed, and there is no real solution to this problem. ASUS simply replaced the product within the (now expired) warranty period to sit out the problem.
The problem occurred after about two years of heavy use:
When I pressed the power button on my BeQuiet Dark Base Pro 900 Rev. 2, nothing happened. My first thought was that something might be defective in the power supply (an HX1200i from Corsair*). I have never experienced a sudden motherboard or power supply failure in standby mode.
After a quick search, it was clear that I wasn’t the only one affected. The solution is to completely disconnect the power to the motherboard by turning off the power supply. After turning the power supply back on, the computer can be started normally with the power button.
A permanent solution is needed.
To permanently resolve the issue, you must set the “ErP” power setting in the UEFI to “S4 + S5,” which is equivalent to disconnecting the power in standby mode. However, this also has side effects:
- Wake on LAN no longer possible
- USB power supply no longer works when switched off
- RGB lighting in standby mode is also not functional
I don’t know of any other solution to get this phenomenon under control. It’s a shame, considering that it was a €400-500 motherboard, which is really far from cheap. Several BIOS updates over the years have not brought about any change.
