GX-Mod.com (http://x360.gx-mod.com/modules/news/article.php?storyid=2145 ) is reporting that the newer Xbox 360 Jasper models come with a new smaller PSU.
The image below shows a regular Jasper PSU and right below the PSU (which is about 1/4th smaller) from an Arcade Jasper-based Xbox360 with 512MB internal MU manufactured in May 2009. The new PSU is still 150W, so no change there.
