I searched high & low and couldn't find any info on if the RM1000X fits the T7500.  I Googled it ("does corsair RM1000x work in Dell Precision T7500") and ran across a Dell Community page that seems to indicate the T7500 can't take a custom PSU.

In Amazon and eBay, the RM1000X did not come up in PSU search results for the T7500.

Are you able to order from Amazon or eBay where you are?  EBay has the better deals on new and refurb Dell PSU's for the T7500.

Sorry to not have better news, but I didn't want your post going unanswered either.

I also went to the Corsair site.  Live chat is open 7AM-5PM (US Pacific Time).  It's 8:50 p.m. here, otherwise, I would've chatted myself.   https://www.corsair.com/us/en/support

Their customer service is available 7AM-11PM (US PT) @ 1-888-222-4346.

Walmart.com or app could also be an option.

I edited my 1st reply above to include Corsair's phone #.

In Australia and my 7500 PSU has just died.  Kept it alive by holding the reset at back then use the power button, but now it is all dead.

Looks like no units in oz as far as I can see so far. 

Would any of these models be okay?

G821T, R622G, or W301G

Is this the RM1000X talked about for the 7500?

Hi,

Sorry for the delay getting back but life is so crazy busy!

I bought a used mobo and found it wasn't the mobo after all, but in fact it was the PSU although it looked like all the voltages were correct.

Anyway the Dell PSUs were too exy as they had to come from US and the post was as much as the unit!

Took it to a computer shop and they put in a compatible PSU for AUD$150.

It now runs like a bird although still showing that the Dimm slot 5 is still not wiorking althought we checked it all out.

Thanks for all the help.
