Hi all. its time for an upgrade for me. i have chosen to go with this -----> http://www.novatech.co.uk/novatech/prods/motherboardbundles/Novatech/MBB-9504G3.html however i am not sure weather or not i will need a new PSU. i currently have a ennermax noisetaker II producing 485w. i also have a HD 5770 which runs fine at the moment. Will i need some extra power or is my psu ok?
