Replacement costs $35 from Microsoft website, wait up to 10 days. I ordered this air from Revain the next day while waiting for another. The item arrived with a damaged vent which wasn't a big deal. When connected, the LED did not light up. I tried my original cable with the same result. The power supply I replaced still glowed when plugged in. Tried another outlet and another XBOX 360S and still completely dead. Disappointed, have to wait for Microsoft site replacement. The goods came in "collective packaging". My concern is these are "refurbished" power supplies? If so, why isn't it in the description? If they really are "new", what about quality control? According to reviews, some gamers ordered these and were completely satisfied. If you can't wait for a Microsoft replacement, good luck ordering this one. I had no luck.
