GTX 1650 SUPER on 300W?

5 and a bit years after I built my PC the graphics card is failing (the computer locks up during standard, non-gaming use with coloured lines and squares over the displays, then reboots. Crash dump says VIDEO_SCHEDULER_INTERNAL_ERROR and DPC_WATCHDOG_VIOLATION. Happened once a week for past 4 months, now twice a week. Uninstalling NVIDIA drivers w ddu's tool and reinstalling hasn't fixed it. Neither has sucking out 3 years of dust)

The GTX 1650 seems a good replacement, but the GTX 1650 SUPER looks much better for £20 more. At some point I'll build a new PC and would like to reuse the graphics card in the new build.

What are the chances of my system plus the GTX 1650 SUPER running on a 300W PSU, rather than the 350W they recommend? I am a casual gamer, the most taxing being Shogun Total War 2 and Anno 1404; I use CUDA sometimes when following AI tutorials and that's it. The rest of the time it powers 2 WQHD monitors for mundane office tasks.

The PSU puts out 22A on the 12V rail and the rest of the system is:
  • ASUS Z97I-PLUS
  • Intel i5 4590
  • Scythe Big Shuriken Rev 2b CPU cooler
  • 16GB Crucial Ballistix vlp RAM
  • Crucial MX100 SSD
  • SilverStone SST-ST30SF 300W SFX PSU
Feasible?
 
Silverstone is a high quality PSU so should be good for the full 300W. Max TDP for the i5 4590 is 84W without overclocking - call it 100W because this is Intel - and the GTX 1650 Super consumes about 100W. That leaves 100W for everything else so you should be fine as long as you don't overclock.
