Constant grasping at straws.
It's ridiculous to say the least, but at least it gives you something to laugh at on a rainy day.
I also think Xbox 360 has a hidden GPU.
Xenon/Zephyr used a 203W PSU, the system consumed 150-177W
Falcon /Opus used a 175W PSU, the system consumed 109-121W
Jasper used a 150W PSU, the system consumed 90-105W
Valhalla used a 135W PSU, the system consumed 70-90W
Methodology can be read here and here
Hell notice as the process got smaller and consumed less power the PSU didn't decrease at nearly the same rate. I mean going by the logic present in this thread, Jasper, Valhalla and 360E are probably hiding a dGPU!
Random fact: PS3 Phat's PSU is rated at 380W, though Phat PS3 has only consumed 160-200W. Clearly there is two RSXs in SLI in PS3!
