Hi,

I tried to install a ABS Tagan BZ Series BZ700 700W into my XPS 9000 and it would not boot. This PSU was bought and installed into my old XPS 420 and has worked perfectly for over a year. The 9000's PSU worked fine in the 420. Anyone have an idea why this is happening.

The reason I want to swap is so I can update my GTX260 for a GTX570 and I need more oomph.

Thanks in advance.
