Is it possible to power a graphics card with a second psu. I acquired a free graphics card, and wanna test it before sell it online, but all my computers only have 300w psu's. I have a spare psu laying around, and wondered if it was possible instead of connecting the computers psu to the cards ide power connector, if I couldn't use the spare psu I have and connect it to the cards ide power connector long enough to see if the card works.
Graphics card powered by second psu possible?

Yes you can run the card off a seperate power supply, but it's likely it wold not be a molex connector (which you are calling IDE) unless it's an older card. Make sure you have the right type of connector for the card, it would be a 4 or 6 pin PCIe power connector. Unless it's an older card, some of those have molex power connectors and I've seen some that use a floppy type connector for power.
