Old PSU for new GPU?

[JupiteL]

I'm currently using GTX 660 which my sister want to use on her computer, it was 2006 system and as you might expect all of the components are old. The PSU brand is asus, not a generic one. Can this 660 fit there? Or is it going to be too risky?

It is 450w, but I'm sure with the unit aging the quality will dropping also.

I would either get a XFX Core 550W so you will have room for overclocking.

I don't have any plan to OC it. It's for my sister and the only thing she knows is the power button.

Plug it in and see what happens.

You won't need a new PSU for a 660. It only has one PCIe connector. Make sure you have one of those and then try it out, 450W ist more than enough for a system with a 660.
