Also driving PSU nearly maxed or even worse, above specs, is less healthy than running it at 70-80%. Obvious, I know Nvidia will aim for 250W. If it turns out that at GTX980 clocks Titan uses 270W, which is quite possible (GTX980; 180W x 1.5), they'll just lower the freq. by 50Hz to stay in 250W range. Thats how they roll I don't see near-future Maxwell based GeForce beating it. And if it does it will be purely due to taking TDP gloves off, but then Titan can be oc-ed too.
