Dell OPTIPLEX 3050 GPU upgrade

Question

I own a DELL OPTIPLEX 3050 and wish to fit a new GPU (GeForce GTX 1660).   I’ve bought a 500W PSU and a large PC case, along with the 24 pin to 8 pin motherboard adapter (https://www.amazon.co.uk/Optiplex-Power-Supply-Motherboard-Adapter/dp/B0758H3WVX/ref=sr_1_1?keywords=Eyeboot+24+Pin+to+8-Pin+Power+Supply+ATX+PSU+Adapter+Cable+for+DELL+Motherboards&qid=1578508329&sr=8-1).   I intend to transfer the innards of the 3050 (excluding the old PSU) into the new PC case.   Can anybody foresee any problems?

Thank you. It’s obviously more complicated than I originally thought. I’m not going to attempt this.

Yah, for short Dell is too proprietary for case swaps.  Case swaps with another brand or even another Dell model are rarer.

I can see lots of problems. In general what you got is not going to work.

3050 has to use 24 to 6 pin not 8 pin connector.

Dell fan wiring is not standard.

Dell power button, usb and front panel audio cables are not standard nor are they documented.

There is no support or documentation for what you want to do.

Memory failures

Memory subsystem configuration activity is in progress. Appropriate memory modules were detected but a memory failure has occurred.
If you can assist to troubleshoot, narrow down the issue with reseating memory and swapping a known good memory if available.
If nothing works, replace the memory.
