Might not be out there. The AX5400 is also known as the X3400 and there are a few 220W PSU's on eBay but nothing higher than 220.
Are you upgrading a GPU and need the extra power?

yeah i bought the Asus Radeon r7 240 4GB OC Edition and they say its using 75 Watt but my older graphics card the Radeon HD 5570 1GB was using 42 Watt so its a difference and cause i overclocked my Asus Radeon R7 240 4gb to 1000 Core And 1000 memory i used the slider Power Control also to +10 so it draws more power for stable overclock. but im affraid it blows my psu.

But i thought maybe i can buy a new case but i wan't to keep my motherboard cpu gpu etc and really i don't know how to get them out and put them back in a new case

Other Question if i change the case and buy a 450 watt PSU do i need to change the motherboard to?, cause i friend of my told me that my motherboard needs to changing if i want a new psu

Here is the service manual which will show you how to take everything out if you decide to: https://www.manualslib.com/products/Acer-Aspire-X3400-1735717.html

It looks like that motherboard is a mATX so you need a case that will take an mATX motherboard (many do). Keep in mind that you will not have an I/O plate to make everything look nice on the back of the case.

I cannot think of any reason you couldn't use that motherboard in a new case with a new PSU.
