RE: Is GTX 1060 graphics card compatible with an older Vostro (motherboard 0YJPT1)
That does suprise me.
It is a Corsair VS550 which is a 550W, 12v single rail. Given that it previously had a 300W basic power supply and the Graphics card is a single fan with max 120W (Theoretical), the step up in power should be plenty. The technical spec of the card indicate that a 400W (min) system should be enough to run the card.
Am I missing something?
