The external power brick isn't the concern here, as we're apparently talking about fans and optical group malfunctioning when being underfed. I don't know the frequency response function of the various models of 360 power bricks but there's nothing it can do if it receives a lower power than needed for a time longer than its relaxation time. What the troubleshooting seems to say is that when the power is unsuitably low you get: - laser diode malfunctioning - fan malfunctioning The first is fairly trivial... it means that you will get more disc read errors. No harm done to the hardware, the software will try to cope. But it might look like an optical reader malfunction to the user. The second is more important: if fans slow down quicker than the chips cool off, you can get out of the safety thermal envelope and damage the chips. Apparently, this is a known issue and is about the design of the chips, fans, motherboard and air circulation engineering. Ideally, everything should be designed so that even when the system is underfed the chips manage to be cooled down enough to not get damaged. One last thing on the OP: saying that "90% of the damaged 360 were attached to a power strip or surge protector for 6 to 12 months" is statistically meaningless to determine correlation by itself. It should be compared to the failure rate of consoles that were not attached to power strips or surge protectors.

Why would the power remain low unless the power adaptors are flawed in some way? The typical power plug ought to be able to deliver at least 20A or 2400W which is far more than any one persons home theatre system ought to use. Maybe im wrong, I don't particularly understand it but from a general sense it doesn't quite make sense to me.
If the fans aren't spinning like they ought to due to a lack of current in a longer term situation then wouldn't the system also be unstable due to other errors cropping up? If that isn't the case then the fact still remains that the system itself draws half the power it did at launch so even if the fans are spinning with half the current they ought to have the system still should remain within the original specifications for heat due to natural conduction/convection and the far lower internal temperate of modern Jasper/Falcon units.
As far as I can tell it makes more sense that whilst theres a corelation between Xbox 360s and power bricks that there probably isn't any true causation to say theres a direct link between the two factors. I.E. Xbox 360s are connected to power adapters, Xbox 360s fail, but theres nothing I can really figure would cause a link between the two without some actual data proving this is the case. As Microsoft faces a large bill for warranty repairs if there is a causation link then they would be in their best interests to mention it.
Tease.
