It's odd that the image depicted on NewEgg shows 2x6pin connectors. But I really don't think the GTS250 needs that kind of power input to begin with. My old 8800GTS certainly didn't. And as mousemonkey stated, the GTS250 is a redesigned 8800GTS G92 essentially.
Yeah, the reviews were mixed but after the promo code and the rebate it ended up being about $73 so I thought I'd give it a try. It runs flawlessly but I wasn't sure if I'd be missing some extra needed power for overclocking without the second 6 pin connector.
So the consensus is that I don't need the extra connector....that is good because I really like the card and don't want to have to go through the formality of a RMA....though Newegg was ready to give me a full refund and pay for my return shipping. Does anyone know of a better deal for the same price??
