Question GTX 1060 in my Dell Optiplex 9020?

[Fardringle]

I've been offered a used EVGA GTX 1060 3GB gaming edition GPU for almost free, which would be a pretty huge upgrade over my current GTX 750 ti.

Unfortunately, the 290 watt PSU in my Optiplex 9020 doesn't have any 6 or 8 pin GPU power connectors, and the motherboard connector for the PSU is a proprietary 8 pin plug so I can't just stick another PSU in there.

Replacing the whole system would be a nice option, but not really a viable option due to budget issues. So I'm trying to figure out if it's possible to use a SATA to PCIe power adapter to make use of the 1060 in this machine. The PSU is a 290 watt Dell branded (made by HIPRO) and it lists the power rails as:
+12VA - 14A
+12VB - 16A
+12VSB - 1.67A

I suspect the answer is no since EVGA says they recommend at least a 400W PSU and that the card itself draws 120 Watts. But I'm hoping for a miracle.

The rest of the PC currently consists of:
i5-4670 CPU (not overlocked) with stock Intel HSF
EVGA GTX 750ti (overclocked to 1510mhz GPU and 3150mhz RAM)
16GB DDR3 RAM (4 x 4GB)
256GB Samsung 850 EVO SSD
2TB WD2003FZEx mechanical hard drive
LiteOn DVD burner
2x 90mm case fans

Odd suggestion but pull the cmos battery for a minute then put it back in then reseat the gpu. My main rig with a motherboard from 2018 worked fine with a gtx960 but when i upgraded it to a 3gb 1060 from 2017 i couldn't get it to post. I pulled the 1060 to get to the cmos battery then pulled it then put it back in and plopped the 1060 back in. Posted fine after that.

The bios was always set to uefi which was weird so why i couldn't get a post prior to pulling the cmos battery on a Asus B360-G Gaming motherboard was beyond me.
