I currently have a Gateway GT5692 computer. I have bought


GIGABYTE GA-MA790X-UD4P AM3/AM2+/AM2 AMD 790X ATX AMD Motherboard

SAPPHIRE 100283-3L Radeon HD 5770 1GB 128-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card

AMD Phenom II X4 945 Deneb 3.0GHz Socket AM3 95W Quad-Core Processor Model HDX945WFGIBOX

My current PSU is 450 watt. I am going to upgrade to 750 but for now will my current PSU run these components along with the stock components that I am keeping (hard drive, etc..)?
 
Here are the official ATI recommended power supply requirements for the ATI Radeon HD 5770 and 5750 video cards:


450 watt or greater power supply with one 75 watt, 6-pin PCI Express® power connector recommended.

600 watt or greater power supply with two 75 watt, 6-pin PCI Express® connectors for ATI CrossFireX™ technology in dual mode.


The recommendations are for an entire pc system. The assumption is you have a high quality power supply. Please take a look at the data label on your power upply and post the brand name and model so we can make a valid opinion.
