no, you don't need another transformer...2000 watt is good.

Xbox only need 200-300watt, 2000watt is overkill. You're not running 10 Xboxes at a time don't you?

You can buy step down from Ace hardware...500w for rm165...thats what am using and it works fine...!!!!

can just use your 2000w stepdown transformer, thats the max power rated, not your actual usage. if you still want to buy, just look for electronic shop. Danga Bay mall shop might have it

For as long as u want technically ..... Assuming u bought one that actually provides the rating it listed and not some alibaba one.
