I have an Alienware Aurora R2 and I'm trying to change the power supply. The one that it came with "Model DP/N 0U597G" do not work anymore so I have purchase an 875W power supply - Model DP/N 0J556T.
Compatible Part Numbers: W299G J556T U595G NPS-875BB A N875EF-00 H875EF-00 - According http://www.ascendtech.us/dell-j556t-875w-power-supply_i_csdelj556t875wt.aspx the 0J556T should work with the current cable that I have now, but it did not. The pin configuration are different.
I would like to know if it should work or should I buy the same 525W DP/N 0U597G model power supply.
