The Xbox 360 box has a hole at the top of it where the bar code of the console is visible. Clerks usually scan this when you buy one. What you need to do it look at the lower left corner of this box. If you peer closely you can make out at least half of the voltage/amperage rating of the unit. The # of amps used by the 12 volt rail is the key to determining which console it is.

14.2 amps equals a Falcon unit (65nm CPU, 90nm GPU). There's nothing wrong with having one of these. You might not be able to see the whole voltage listing just through the peep-hole, but you should at least be able to see if a 14.2A or 12.1A is just to the left of the "5V".

12.1 amps equals a Jasper unit (65nm CPU, 65nm GPU). This voltage rating is also listed above the power input, but of course you can't see that when it's in the box.

Another way to tell if your model is a Jasper. You can look at the power connector when you unpack the console. If you can see two flat bars on top of the 6 metal connectors, then you have a Jasper. If there's only one long bar, then you either have a Falcon, or a refurbished Zephyr board.

There has been a lot of discussion about lot #'s, power supply ratings, and things of that nature being used to find Jaspers. I have found those to be unreliable.

14.2 amps = Falcon unit;
12.1 amps = Jasper unit.

The best way to improve your chances of getting a Jasper is to go for an Arcade model. This seems to be the richest Jasper series yet. And as far as Elites go, nobody has spotted any Jasper's so far.

The thing is not every Arcade is a Jasper, some of them are Falcons.

The speciality of the Jasper chipset is that it is expected to improve the reliability issues that have plagued the Xbox 360 since its launch. The biggest change is the newly redesigned motherboard, which should help alleviate the infamous Red Ring of Death problem. Attached to the motherboard is a new 65-nanometer graphic chip. This new chip will consume less power and run cooler.
