You could try using the Area 51 R2 Desktop OEM PSU. Click here to see another thread from the Alienware Arena forum about this upgrade. We have seen the Corsair working without issues but we cannot confirm if it’s going to fully work since it’s a third party product. You could try posting this in the Alienware Arena forum for more information.
Alien-Rod / A-Rod tried to link you to an R1 post at Arena; we have our own post here in Coliseum: Aurora ALX 875 Watt Power Supply Upgrade To Area 51 1000 Watt Power Supply Upgrade:
Measurements for a power supply are 5.9" x 3.4". As for length, the 875w in your case is about 6.5", you can get away with a psu of about 7.5" max, over 7.5" you might lose the left hard drives bay. 1000w - 1200watt psu's tend to be 7.5" & under, so they do fit, Corsair's fit, yes, check the forum.
