Will a MSI Radeon R9 270 2GB work on 450w?

[deadsite22]

I'm looking to upgrade my graphics card to the MSI Radeon R9 270 2GB but i only have a 450w power supply. My pc specs are

Core i3-2120
2 Hardrives
1 Stick of 4gb Ram
1 120mm Fan
Motherboard is one which was taken from the acer X3995

Yes it will be sufficient. What is the brand and model of your power supply?

It should work fine. The R9 270 has a recommended PSU of 500W. I wouldn't recommend overclocking with this PSU, though.

I could not find a power supply requirement on MSIs page, but I did find one on a match card from PowerColor and it is stated that it requires 500W. If its a good quality PSU you might be able to get away with it, if not, its a risk.
