Will this PSU fit my case?

They make smaller ones but most are the same size.

This one you listed on Amazon is the correct size for you. Your old one is an ATX PSU and so is the new one.

I am 95% sure this will work for you, however, without seeing your current setup, I do not want to say for sure the new and the old PSU listed here have the same plugs etc. I usually tell people to remove their current PSU and bring it with them to the store, however, you are looking at Amazon for this one.

I am from the US and have never heard of this brand so I have limited knowledge on it.

confident, it is going to actual in great concern into that case, yet i might set up it after the motherboard with the aid of fact it would want to be a solid squeeze attempting to get the board in after the provision is in place, thats why i want a case with the potential furnish fixed on the backside of the case with the aid of fact it frequently aspects greater beneficial section.
