I found one on Ebay http://www.ebay.com.au/itm/Acer-Aspire-X3810-X1800-X1420G-X3400G-X3812X-Z3100-Power-Supply-DPS-220UB-A-/221117620252

From what it says it is a Delta DPS-220UB and it is a odd form factor PSU and i cant find much in the way of form factor

I forgot to add that i was planning to change my casing into a larger one and so i don't need a small factor psu i also wanna know whether if a psu is compatible or not.
