I'm considering ordering a Studio XPS 9100. I understand it has a different power supply than the XPS 9000. I'd like to know whether the XPS 9100 has the same issues with non-sine wave UPS units as the XPS 9000 does so I will know whether I need to replace my UPS. Any help greatly appreciated.
I did not receive any replies to this question, but I did order a Studio XPS 9100. I am happy to report that it works just fine with my old APC BackUPS Pro 650. I cut the power to the UPS six times and the 9100 kept right on going without a hiccup. Apparently, Dell improved more than just the capacity of the power supply vs. the XPS 9000/435T.
Thank you JDXTR for replying to your own post. I had the exact same question as you and your experience has answered it for me. Very rarily do people ever follow up on their questions. You are great !!!
SOME of the "Active PFC" power supplies do require "true sine wave" UPS systems, some require UPS systems that have a less than 4 ms switching time and finally some will work with almost any UPS. And this is throughout the industry, not just Dell. Even new standard ATX power supplies fall into this as almost all new power supplies are the Active PFC type (which are greener).

I am so confused. Some are saying you can use this one with the Dell Studio XPS 9100 desktop, others are saying you cannot. Which is it please?
And what about using this with the Alienware Aurora (basic) desktop? Thanks.
Also thanks to the OP for starting this topic, very informative.
I'm still using my Studio XPS 9100 with my old APC Back UPS Pro 650 with no problems. I can't comment on the specific BX1500G model you are asking about, but I can't think why it would not work. To be sure, I suggest contacting APC, telling them that the Back UPS Pro 650 works, and asking if there is any reason that the BX1500G should not work. I have no idea what to say about the Alienware Aurora.
My contingency plan, if the old Back UPS 650 did not work, was to purchase the CyberPower PP1000SW, which at about $240, is about half the cost of a pure sine wave unit from APC. The CyberPower gets good customer reviews on Amazon, including from some who had Dell Studio XPS 9000, which was the problem child with other UPS units, including the BX1500G.
Sadly, both Dell and APC were very stingy with any useful information when I was looking for it.
BTW, I still like my XPS 9100 a lot.
Thanks again for sharing your experience, it is very valuable for those still trying to decide. Glad to hear you like yours. I wish there was a store near me that carried the 9100 so I could play with it, closest I've seen is the 8100, but I guess it's similar.
