Hi Bernardo!
Is this the one you need? https://www.ebay.com/itm/225949451141?itmmeta=01J2TDHAV9XNFNKYN42Z6GB0YV&hash=item349ba30385:g:BrYAAOSwmtVlm056
You also have the 60pin ones: https://www.ebay.com/itm/234412696201?itmmeta=01J2TDHAV9K46PS9BC1VWQS85J&hash=item369415e289:g:B-cAAOSwZthiAuqS
Both of those are for the PS3 Phat. But if the Slim has the exact 24pin one, like yours, then it should work!
Let us know how it goes!
