Jasper Is Here: A Look at the New Xbox 360

Confirming Your Jasper
If you can physically open the box, there's another way of confirming that you have a Jasper without even opening the plastic bag that the console comes in: look at the power connector on the Xbox 360 itself. Each Xbox 360 generation has a power connector that's keyed differently so you can't use a lower powered power supply on a console that requires more power. Now all Xbox 360 power supplies will work on newer consoles, but you can't use newer power supplies on older consoles. Make sense? Let me explain:
The first Xbox 360 (Xenon) needs a 203W power supply. Falcon needs a 175W power supply but can also work with the 203W unit (it just doesn't need to draw that much power so the 203W unit is overkill, but it'll work). Jasper needs 150W but can work with a 203W and a 175W. In other words, the Xbox 360 power supplies are forwards but not backwards compatible.
If you get a Jasper it's not guaranteed that you'll get a 150W power supply, Microsoft still has a lot of Falcons and Falcon-parts in its distribution system so some Jaspers have been sighted with 175W power supplies. If you end up with a 175W unit it's not a big deal, it's going to be slightly less efficient than the 150W unit and your system may end up drawing an extra few watts but it's not a big deal at all - you'll still be far cooler/more power efficient than a Falcon (and possibly be red-ring-free).
To prevent an under powered power supply from being used in the wrong Xbox, Microsoft keyed each of the three Xbox 360 generations differently. The chart below explains it all:
If you see one flat bar on top and a square peg in the middle of the power connector on the console itself you've got a 1st generation Xenon or Zephyr board, these machines use 90nm CPUs and GPUs. If you've just got a flat bar on top with no square peg in the middle, you've got a 2nd generation Opus or Falcon board, these things use 65nm CPUs and 80nm GPUs. Finally if you've got a flat bar split in two on top with no square peg you've got a Jasper, that's a board with a 65nm CPU and a 65nm GPU.

Well, after receiving my 360 back from it's THIRD repair (they sent me an Opus to replace my Xenon) and finding that it kept throwing me DREs at random, I decided to hunt for a Jasper today.I bought an Arcade unit from GAME here in the UK. I asked if I could have a look at the box first and they said no, so I told them to security sticker it because it was a "surprise gift". Turned out to be a Falcon (14.2A). So I'll be taking that back tomorrow.
In the meantime, I went to GameStation and asked and they let me look at the boxes - second one I looked at was a Jasper. It was really easy to see as well, didn't have to move the console, the 12.1A rating was immediately viewable through the cut-out, so I bought it and it works fine. That's another £130 I've thrown at MS - and all because I really can't be bothered to wait another 3 weeks for them to repair my replacement, which is a pretty laughable concept considering I'd had it all of four days.

I had the privilege to use an Xbox 360 Pro (60gb version) last weekend at a friends house. He had just bought the box, so naturally i wondered if it had a Jasper board in it. He told me that he wasn't sure, so I checked the back of the system. Sure enough, it had a power rating of 12,1 A. The power supply itself was a Falcon power block, but the power rating and power input jack on the Xbox both matched up to Jasper specs. I would post pics but my sister didn't let me use her camera. I will see if I can get him to send some pics via email.XtraCrispi - Friday, December 19, 2008 - link
I just bought an Xbox 360 via Dell and when I got it today I was excited to see that the manufacture date and lot numbers corresponded to what I had read for the Jasper. However after finding and reading this article I've come to realize I've got that rare breed you warned about. It's the 1st gen Xbox with HDMI and a manufactured date of 10-23-08. WTF! So mad.I might just return the thing because why spend current model prices and take an old model car, right? (No, this Xbox ain't a classic.)
Good thing I called Dell before I opened it and complained that the packaging was terrible and the Xbox box was damaged. They said I can open it up and try it out and send it back if it's damaged. I might just do it, get a refund and go get a Jasper at a local store.

Wow! I was told in early Nov. that MS will not issue pre-Jasper in retail channels. They will be offered as repair replacement or refurbished only.I am lucky then and just received my Arcade from DELL today. I wasa a bittle concerned because I used discount coupon. Before I opened it, I confirmed it is indeed Jasper: 12.1V and made 10-18-2008 (3 days after the pictured). The lot#, built-in 256MB memory and bundle label and everything described. Now after opened, the 150W PSU and power connector all confirm it is Jasper. It even has one flyer for the New Experience update.
Great article!

Hey there allI like the article, it helps those wanting to ID their systems well, except for my 360, which...makes no sense.
My 360 (Lot 0745, Made Nov 2007), uses a 175Watt PSU and the Falcon PSU input, but indicates that it uses 16,5A for its 12V rail, an indication of a Zephyr?
Now I WAS 100% sure I had a Falcon, and I'm still pretty sure, but this has confused the hell out of me, surely the Zephyr wouldn't even work with a 175Watt PSU...would it?

You're not going to have a Zephyr on Falcon current, but you could have a Falcon on Zephyr current.Don't sweat it... you were probably right that you have a Falcon.

I have two words for Microsoft and any other chip maker fo that matter....Gallium Arsenide! Heat would be a non-factor because there is very little resistence with said substance, therefore it would increase speed also.turbobozz - Wednesday, December 17, 2008 - link
What are you smoking?You don't know what you are talking about.
Using GaAs would make it far, far more expensive.
And it you're very much misrepresenting the true benefits GaAs has over Si
(Which aren't generally applicable to the 360.)
Wikipedia has a decent article on GaAs... look it up.

so far my late 2006 xenon has been working flawlessly, i'll keep my fingers crossed that it stays that way. i wonder if anyone has any records as to what ratio of the failed units were xbox live gold members/players :)i don't do multiplayer, so perhaps my xbox loves me for not putting it through all the trash talking wannabe kid drivel.
i can hope can't i?
