Through the usage of another thread, I was able to come to the conclusion that the XF AMD Raedon 7750 HD GDDR5 1 GB was the best card for me. However, there is a problem: The recommended specs are 400-450 Watts, but I've seen on many reviews that a 300w psu works fine. My Vendor said that the installation would not be possible, due to the allegation that my psu didn't have a pci connector. From the reviews I've seen (about the card), the 7750 does not need a power connector. The shipment should be coming sometime this weekend. Should I go with my gut? 'Or should I buy a new psu? Thanks in Advance!
