Yesterday I got invited to participate in the SC2 beta. Having been running intergrated graphics on this PC since day one i went to bestbuy to buy a graphics card. The one that I purchased was a PNY Verto geforce 9400 gt. It says that it requires a minium of 300w to run. I have a 250w power supply in my pc right now. So far the card is working like a champ. I have had no crashes or any indications that there is anything going wrong. Is there a chance of something going wrong if i don't upgrade power supplies right away. I am planning on upgrading within the next two weeks just did not have that much money to spend right away. My friend is giving me a hard time as he wanted me to wait and get it all at once so i can't turn to him for advice on anything right now. Hopefully you have good news for me haha. Peace for now, Skylash.
