Hi shan383,
Processor upgrade can cause various issues. If it is not seated properly it can lead to motherboard failure, it can cause overheating issue if thermal paste is not applied properly or the heatsink and fan are not seated properly. It might require other parts upgrade like power supply and heatsink assembly. It can cause complete system crash. As I mentioned in the previous post, issues arising due to the upgrade will not be covered under warranty.
Please feel free to reply for any further questions. I will be glad to assist you.
The unit you've asked about uses the same amount of power, so heat shouldn't be an issue. That said, you won't see your $500+ worth of speed boost from it. Very rarely is there enough difference in speed between CPUs a given system will take to justify the price. When you buy the system, the $50-100 for an upgraded CPU makes sense sometimes -- afterward, not so much, because of the cost.
Beware any suspiciously low cost CPUs - the market is rife with remarked processors, and unscrupulous sellers - and note that Intel does not warrant "tray" or OEM CPUs to the end user - the only warranty you get is from your reseller, so be sure that business or person is reputable. If they disappear after the sale, so does your CPU warranty (and upgrading the CPU on an in-warranty Dell will void the warranty on the system).

Hi shan383,
The wattage of ac adapter depends upon the type of graphics card; your system is shipped with. Dell™ XPS™ L702X is shipped with 130-Watt (integrated graphics) or 150-Watt (discrete graphics) AC adapters.
Please feel free to reply for any further questions. I will be glad to assist you.

The 3840QM should work - but at $568 list price per unit, won't be an inexpensive upgrade.
