PowerColor HD 5670 V2
I'm looking to upgrade my GPU however my choices are limited due to the fact that I have a 300w PSU on my HP desktop. So I found this awesome deal on a PowerColor HD 5670 (http://powercolor.com/us/products_features.asp?id=258) but the site says it requires a 400w PSU. I used the "extereme power supply calculator" and it recommends 293 watts. So my question is will I be able to run the card without frying my computer? Thank you for your time!
