My Dad has been bugging me for a long time to get him different computer, his current DDR2 era one is terrible, the GPU is dying and just a few too many open Chrome browsers bring the tower to a crawl. Running anything besides Runescape at 720p/lowest settings is out of the question. So for his birthday this year I scored a great deal on a used HP Elitedesk 800 G2 TWR. It's got the standard 280w 80 Plus Platinum PSU, an i5 6500, 16GB of RAM, 120GB SSD for the OS, and a 1TB HDD. Runs great and looks pretty clean. It's just waiting for a graphics card. I've been reading all the forum posts about it and have watched far too many videos. As it stands the best that it will normally accommodate is the GTX 1650, however it's very tempting to order the best quality sata to 6pin adapter I can find and go with a 1650 Super. I know there's a lot of stigma and risk surrounding using adapters for GPUs (with due reason) and I know the sata is only rated at about 50w, but the card is only 100 TDP, just 25 more watts than it's older, slower brother. It seems that many people are trying to use the adapters for GPUs that have a much higher TDP (120-180w), and that trying to push it that far could certainly be a cause for concern. Is it asking too much for it to help run the Super? How much of the maximum 75W will the PCIE slot actually provide? It's hard to ignore the performance difference for only 10-20$ more, but is it worth the risk?
In case it matters, my sata power cables from the PSU are 20AWG.
