I'm going to buy the gtx 570 and I also need a new PSU unit for my computer. But I don't really know that much about PSU's. And when I search, anything above 650W seems quite overpriced (150 euros). So I hoped somebody could help me out to find a good(650W or more) but not too expensive PSU with all the necessary connections.
