i thought the socket for xenon and jasper is difference???
Ya it is different. Old power brick can fit in newer console but newer power brick cannot even fit in older console. This is to prevent the newer power brick being use in older console. Older console need more power. Newer power brick doesnt supply enough power and might damage the older console, so MS design the socket differently so newer power brick cant fit in older console.
Maybe its hard to understand what i type so i quote this

The launch day 360 requires a higher power supply. Since the PSU will only draw from the wall what a system needs, the higher end PSUs can work with the newer systems, but not vice versa.
Basically, the Xenon (launch) and Zephyr (HDMI) power supply (203W) will work on all 360s, even Falcon/Opus and Jasper.
The Falcon/Opus power supply (175W) works fine on Jasper, but not on Xenon/Zephyr.
And the Jasper power supply (150W) only works on Jasper.
The connectors were designed rather well, so while you can take a Zephyr/Xenon PSU and plug it into a Jasper, a Jasper PSU wont fit in any older model. A Falcon PSU won't fit into a Zephyr/Xenon.
