The problem with video card manufacturers is that they refer to the total output of the PSU not just the peak power. A PSU marked as 400 Watt is referring to its peak power, not the total power output (unless otherwise peak and constant is the same).
Peak power is intermittent and not the constant output. If you run at peak power, then add a usb device like a flash memory stick, there is no power above peak so your usb drive either fails to work or your PC shuts down from the power surge.
Also with peak, everything runs hot and mnoisily, usually.
Even so, apart from that, my PC shop guy, a few years a ago (I got a Palit video card, never got it working) said that Palit was a poor design and often died rather swiftly. I was hoping it was not the case with your card.
My Palit card was purple but only 256mb with a small fan. I still got it somewhere, just keeping for reference.
