HICTOP DIY Prusa I3 - Finished assembling but auto home does nothing

[ddoiron]

Thanks ! I really appreciate the help.

ok so I assuming that a USB 5V is not enough to heat stuff.
So I need to troubleshoot the issue from the POWER SUPPLY.

I dont see any voltage coming out of the PSU to the main board....
And now I just opened up the PSU to see a blown fuse:

First, is this a blown fuse? And if so, can I replace? or do I just purchase a new PSU?
Also, could I have caused the fuse to break? I put it on 110v from 220v prior to plugging it.
