Hi, I'm just going to throw this one out and see if anyone's had this particular or similar experience.
I have a Dell XPS 8700 and wanted to upgrade my GPU to an nVidia GTX 1070. Multiple forums have said this is doable (even some youtube videos). But what most neglect to mention is that the stock PSU (460W) in the Dell only has 6-pin PCI-E connectors, and the 1070 demands 8-pin.
When I asked about getting a cheap adapter (6-to-8) almost all advice was against that. Worse was when I proposed sticking the 6-pin into the 8-pin and 'winging it.' General concensus was to just go out and purchase a new PSU. So I did.
It's a CoolerMaster v650. I installed it and when I power on, nothing happens. All connectors are in, same as they were for the old PSU, with the new 6+2 connection for the 1070. Still, nothing.
So I panicked and removed the v650 and installed back in the original Dell PSU (and old graphics card, a 645) - and everything works fine.
So, what could I have possibly missed? Returning this PSU is going to be a chore, as I'm stationed in a developing country and the computer store I purchased this from, is in the basement of an apartment complex.
I guess my main question: have any Dell XPS owners experienced DOA with new PSUs, and had to return to the stock unit? And/or is there something "unique" about the connections inside an XPS 8700 (especially the 4-pin CPU)?
Thanks for reading!
