zip - It might be the other way around. It could be considered a question about the capabilities of the Intex power supply. I never heard of it. Turns out it is not a high quality, high performance psu.

It was difficult finding information about the Intex power supply. It does not appear to be available in the USA. I found references to it in other countries. It appears the Intex 450 watt power supply has a +12 volt rail rated at 20 amps. It should be sufficient for a system with one ATI Radeon HD 4670 video card.

EDIT - A high quality 450 watt power supply will have a +12 volt rail rated at about 30 amps. The Intex 450 is low but I think it should be okay for one HD 4670.
