power supply for xbox 360 with a 175w connection plug

Not sure why you couldnt find it. I just googles 'xbox 360 175 watt power supply' and got dozens of results of genuine xbox 360 175 watt power supplies from ebay and amazon. Took about 5 seconds.

Also Microsoft stopped supporting the older models well because they are old.

Original 360 console power supplies are forward compatible. 203w, 175w, and 150w power supplies can be used with 150w consoles.

[quote user="Sage to Rage"]Well either way he would still have to get the correct year and wattage because all Xbox boards have different plug in ports.[/quote]That's why I said power supplies are forward compatible. The original 203w supply will plug into
a 150w Jasper.



Note that they are not backwards compatible. A 175w Falcon supply will not physically plug into a 203w Xenon console.



Microsoft seems to have done away with this for the 360 S as Trinity and Corona plugs appear to be identical. A 120w Corona brick plugs into a Trinity console.

A 2006 203w power supply wont plug into a 2009 Xbox 360 for safety reasons and to protect
the consoles from insufficent power

An original 2005 power brick will plug into any original 360 model. Again, forward compatible.

There are a few ways to tell. First is manufacture date. Second is wattage of the power supply. Third is the system amperage.

Here is how it breaks down.

Problems with your Xbox 360 console can sometimes be solved by making sure your power supply connections are firmly connected. Try these steps in the following order:

1. Turn off the console.
2. Unplug the power cord from the back of the console.
3. Unplug the power supply from the electrical outlet, and then unplug the short cord from the power supply.
   
4. Plug the power cord back into the console, then plug the power cord back into the electrical outlet and the power supply.
   
5. Make sure that all three power supply connections are firm.
6. Turn on the console, and check the light on the power supply.

Also remember that

• The power brick like the xbox itself needs to remain in an open space, and clutter free
  

• tampering with the Xbox can void the warranty as well as lead to banning.
