Member Pasolaminado posted the below info in the forum but the PDF swap guide is no longer accessible so I've reposted it here so other users have access to the PDF (tonight & in the future), original post below
"I updated my Alienware Area 51 (R1) with an Intel Skylake Processor, EVGA motherboard and EVGA 1600 P2 power supply. Forum member Cass-Olé helped me figure out the power supply and wiring requirements for a successful swap
Cass-Olé updated the following article that covers the EVGA T2 P2 G2 Power Supplies, which have their own unique cables and pin out. The information is not applicable to any other model PSU
Instead of having a mile long post I compiled the process I went through for my component swap in a PDF file (ATTACHED)
Wow, awesome pdf, thanks for sharing in this forum. Following.
