I installed an Asus GTX650 graphics card into a new computer (i3-3220, reasonable decent motherboard that would support it). I failed to take into account for the PSU, which just about matched the minimum specifications needed for the card.

Out of the box and installed, I had no problems, but soon noticed this problem and corrected it with a decent PSU after I started having graphics problems in games, and detection problems.

At the moment, the card is no longer detected by any nvidia drivers, going from the latest, to the one provided by the CD that came with the GPU, nor any released in-between.

So, is it a driver issue? If so, how can I sort it? And if I have damaged it, get a new one?

Does it work in another computer, or same issues? – Darth Android May 3 '13 at 22:28
What operating system are you using? Does the operating system (or even the BIOS) detect the card (even without drivers, it should recognise that there is something plugged in)? When you say "corrected it with a decent PSU", what PSU did you upgrade to? – Ash May 3 '13 at 23:51
Drivers do not get magically corrupted when your PSU is too small. Hardware on the other hand might not like a PSU failing (esp. if it does not fail gracefully). – Hennes Mar 15 at 13:11
