Pascal expected wattage

[Canonical]

I'm building a new PC but not buying a GPU till Pascal, just gonna use the integrated graphics till then. I was wondering if I should get a 600 or a 650W GPU. I've used the wattage calculator (http://outervision.com/power-supply-calculator) and put in a GTX 980Ti, since that's about the level of power I expect to buy with the next gen. I got 531W for load wattage and 581W for recommended wattage for my specs. Do you think that Pascal will require more than a 600W PSU? Thanks

650-700 should be good

step 1) never use wattage calculators

 

step 2) look at real power measurements of that GPU on google

 

step 3) no pascal will not require more than a 600W PSU for its top ti card

Thanks for the tip

What's wrong with wattage calculators? They add or remove too much?

600 is more than adequate if buy a high quality unit.

 

I run an R9 290 vapor-x OC with i7 3770k, multiple drives, fans, LED on a Seasonic 550 watts.

Still have plenty of room for overclock headroom on both CPU and GPU. I have even try load testing with furmark and Intel burn test simultaneously (ridiculously stupid load) and it is stable.

 

AMD Polaris and Nvidia Pascal are built on 14nm finfet which will be more power efficient than current gen 28nm GPUs.

wattage calculators always overestimate to account for crappy PSUs that cant deliver their full rated power

he should just buy a AX1500i right away. That way, he is sure to be able to power ALL the GPUs...

 

mind you, at 90% efficiency at 10% load, wasting power is a non-issue
