Will the T7500 1100w power supply fit in the T3500?

Greetings Dell Precision Forum!

I have a Precision T3500, and I am looking to get a new video card for it.  However, the 525w power supply it came with only has a single 6-pin connector for GPU and the cards I am looking at may use up to 300w alone and require either 1x or 2x  8-pin power connectors.

I see the Precision T7500 has a 1100w power supply, and can be bought used for a reasonable price.

Will the T7500 power supply fit the T3500? If yes, can I just leave the cable harness in place, remove the old power supply, install the T7500 power supply, then reconnect the cable harness?

Thanks!
