here is my dilemma. Bought a RROD system with intentions of repairing for my nephew as a gift. I know giving a broken gift that has been fixed kinda tacky i know but he knows the story and is just happy to get a 360 so its ok. I bought the consoles for 40 bucks and it had no HDD and no Controller but did come with the PSU brick and the video cables. when i picked it up from the guy i checked to make sure everything was there and we parted ways. when i got home i discovered that the guy had gotten RROD on this box and he went out and bought a new arcade unit to replace it. Thats why he didnt include controller or HDD cause he kept to use on his new arcade unit that of course has no HDD. I would have done the same. But instead of packing up the RROD system with the cables that came with it originally he just took the new arcade unit out of the box and put the RROD unit in the new arcade units box without swapping cables. for him this was good cause the old power supply will work on the newers systems fine as the PDB simply adjusts power levels and what not. But for me this is bad news cause the newer falcon PSU does not fit into the older Xenon unit. see picture it shows the power input on the console. http://www.360drives.com/images/boards_power_connector.jpg as u can see the xenon has a post in the middle while the falcon does not. so when u look at the PSU output plug that goes into the 360 the new falcon PSU has a piece of plastic in the center so it will not fit into the Xenon unit. I was thinking maybe i could just snap off the post in the xenon unit and then the plug would fit but i do not know if this post has any function such as a ground(i doubt it) or maybe just an attachment point. Also if i did get it to physically fit would it be able to power the console since the newer PSU is rated at 175w while the older one made for the xenon was something like 203-250 i think. or should i be looking at the amps not the wattages? would the unit be able to play fine or would it be at risk for further damage?
