Re: can I use a 430 watts PSU for GTX 460?
When I had issues with a GT 220 from Zotac They actually told me to run it over night. So I did and it stayed at stable at 65°C and did not lock up the system. So running it longer than an hour should not be a problem unless there is a hardware issue which is what you are looking for when you run this test. Run it for an Hour or 2 and if it is stable then you should be fine, if it is not and locks up then replace the Power supply.
