I have an old OEM machine, specific model: https://www.cnet.com/products/dell-inspiron-570/specs/ and I was wondering if I could put a GTX 650 ti into it. The main problem is that there is no 6 pin power connector. Im asking to see: 1. If the adapter itself is safe and 2. If the psu itself can handle the card. Any responses at all would be greatly appreciated. Thank you for your time and goodnight.
