Alienware area 51 Power supply faulty, how to get a replacement? how to upgrade to 1050w?

I am not sure about the $129. I thought that Desktop Out of Warranty support started at $59. Click my DELL-username in blue, then click "Send a Private Message". Provide to me the service tag number so I can look up the components.

I have a Area 51 R2 850 Watt Delta PSU that I can sell you for 50 bucks..... Or you can just get a EVGA PSU for an upgrade

DPS-850AB-2 A  .Just open the desktop.

If my computer went to blue, restart itself, or cannot connect WIFI, The service would be what I need. Now, the computer DIED, what can you do ON THE PHONE.......?

I just want to get a replacement.

Will this service included testing faulty box if I send the faulty power supply to dell? 

I do not expect this service will give me a replacement. 

But I ready got a technical checked, (what dell help line suggested me to do).

I need the service tag number to know what power supply part numbers you might need.

You would not send any parts into Dell to test.

Call 800-822-6031, enter your Express Service Code. You will be routed to the appropriate technician. For $59, the technician will diagnose the problem to determine if there has been a hardware failure. After diagnosis by a Dell technician, a 3rd party service provider will contact you to arrange payment and schedule a convenient time to come to your location for part replacement. You will be billed directly by the service provider.

Thanks for reply

the tag is alienware AREA 51 R2

1. what is Express Service Code?

I removed the tag from view. I sent you a private message with a link to your page showing the express service code. The system warranty is from 1/22/15 to 1/23/16. So there should be no charge for you to contact regular Alienware Support. They should troubleshoot the system to verify that the power supply N0DMP is defective. Then arrange the part N0DMP replacement. But, did you buy this directly from Dell or from a reseller? It shows that it was sold out of Dell Canada. If you did not buy from Dell directly, you must transfer the service tag into your name before any service can be setup.
