Which power supply to buy for a 360?

post #1 of 4
Thread Starter 
I am looking at several different power supplies for an Xbox 360. However, there are at least 4 different power supply variations for the 360, that I know of. The one with the highest wattage, is 203 watts. I think some of them are as low as 120 watts, for the newer 360 hardware revisions.

So my question is this. Can I just buy the highest wattage power supply (the 203 watt) and use it on the lowest power consuming 360? I mean say I buy the higher wattage power supply, but I end up with a 360 that only needed the lowest wattage power supply. Will using the higher watt PSU with the lower wattage unit, cause some kind of unwanted effect for me? The way I understand it, the low power unit would simply draw only the power it needed, and nothing more. Making it safe for me to use with the high power PSU. I mean, that's how computers work, anyway.

The reason I am asking is because I got a buddy that will sell me the high wattage PSU for a 360 for $10. Hard to beat that price. But, I have no guarantee that I will end up buying a 360 that was built to go with that exact power supply. So I want to be sure that I can use the higher wattage PSU, with any 360 out there, including all the ones that might need less power than that PSU is capable of outputting.

you can buy the highest and use it on the lowest..

But what I would do is:
1. chuck 360 out of window
2. build Gaming PC
3. plug it up to the TV
4. use wired Xbox controller for games.

For $10 go for it. Then get it home, check warranty status, and if out of warranty, open it up, dust it out, and look over the capacitors and check for bulging or leakage. That, and signs of scorching are bad news. Remember, a PSU with bulging caps may well appear to work, it'll just put out some nasty ripple and out of spec voltages.

You can use any PSU powerful enough to do the job, even if it has more capacity than you draw from it. It's just like regular PC units, you can run that single core P4 at stock with a 9400GT on a 1kw PSU if you want to (and are daft enough to blow that much money on a PSU), but a 300w unit is a more economical choice.

heh rig in sig. Although I will say that consoles have their place. Even though this one isn't for me. Its for a friend who just wants a 360. I wanted the challenge of building one out of spare parts, and he couldn't really afford a working built one. So I thought I'd kill two birds with one stone and I'd get to build it, and then I'd sell it to him for what I had in it.

Which wouldn't be much. I'm figuring around $70 total for the complete working system, including controller. I think thats a savings of roughly $50 over buying a used one off ebay or craigslist or something.
