Hi, I'm going to be moving to Europe for a few month's and wanted to bring my shuttle pc with me. However, there's no switch on the back to change the voltage from 110 to 220. It says on the side of the power supply that its rated from 100-240v and that it is a switching power supply, but I can't find any documentation on how to switch it. The model no for the power supply is PC35I2402 if that helps. Please help! Thanks

I'm guessing the PSU has active PFC (Power Factor Correction)

Here's a link that explains the basics.

I reckon you'll be fine if you just plug it in and go, but then again i've been known to be wrong before, see if theres any documentation with you're PSU that says what type of PFC you got.
