Did i get the wrong Xbox 360 power brick?

I just got an xbox 360 elite made in 2008 with a 175w power brick. The powerbrick does fit in the unit however there is discrepncy in the DC outputs. On the console it says 12V---16.5Amps but on the power brick it says DC output is 14.2Amps. From my understanding, to get amps you divide wattage by voltage. 175W/12V = 14.6A and 203W/12V = 17A. If i am going to power a 16.5A Xbox 360 wouldnt i need the 203W power brick and not the 175W?

Endgadget source:

203w psu will work with all xbox's. (16.5A, 14.2A, 12.1A)
175w psu will only work if it says 14.2A or 12.1A.
150w psu will only work if it says 12.1A

But if it fits in the system doesnt that mean it is the right one? I heard each console and power brick have 3 seperate fittings so if it was wrong psu it would not fit? Im so confused.

well let me put it this way ... plug it in ... does it work? ... if yes then stop worrying theres nothing wrongpenpusher

RROD, wont even work, general hardware failure....:evil:

Ibought a referbished 360 from newegg and got the RROD first time I plugged it in. Long story short it was the power brick. They just sent me a new one.
