Question Old tx750m or extra power connector

[lazo1999]

So im planning to upgrade my gpu but my PSU has only one PCIe connector (CX450).
In my country 980ti's are very good value but they draw 250W and need the second 8pin which my psu does not have.
Should i buy an old TX750M (orange) PSU i found for cheap or just a molex to 8pin connector?
450W is enough i think for Ryzen5 3600 stock and the 980ti
There is also option for Corsair CX750M (green) and Thermaltake Grand Toughpower RGB 650W Gold Full Modular but are a bit more expensive

If your PSU does not have the required PCIe connections, then it was not designed to be used for higher power GPU's. Molex to 8-pin is not a good idea. The green label Corsair models are best avoided. Grey label Corsairs are acceptable. The Toughpower series are acceptable. Do you know how long the TX750M was in use? The orange label is likely about 7-8 years old.
