Will I need to get a new power supply for a R9 270 on my system?

i'm looking into upgrading my Video card, and it looks like the MSi R9 270 is the one I want. The only problem is, I'm not sure whether my power supply can handle it.

Current Components:
Intel Core i3 550 3.20 ghz
XFX Radeon 5670 1gb
Antec Basiq 450w psu
6gb of RAM

If that isn't enough power, could you give a link to a good psu for under $70?

For a system using a single Radeon R9 270 graphics card AMD specifies a minimum of a 500 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 28 Amps or greater and have at least one 6-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

The Antec Basiq Series 450W (VP450) power supply unit, with its maximum combined +12 Volt continuous current rating of 30 Amps and with one 6-pin PCI Express supplementary power connectors, is sufficient to power your system configuration with a single Radeon R9 270 graphics card.

Thank you very much, that saves me quite a bit of money.
