Hi, I have found that the 7850 has quite good specs, and seeing as I've never built a mining rig before, I thought it would be a cheap enough card to give it a first go with.

My questions are

1. I have a PSU of 350 watts. According to litecoin.info, the 7850 only needs 100-something watts... but according to the official AMD spec, it requires 500 or 600 watts.... Why does litecoin.info report much lower watts, and what is the true watts required?

2. My motherboard is the Dell 0m017g, and it says it has 1x PCI x16 slot, and I've checked it myself to see a long PCI-looking slot... But I just wanted to double check whether this is the right slot for the 7850.

Thanks.
