Am I missing something?

Recommended Posts

Thanks Evan. Great power supply! I think with all the next gen chips and GPUs (both AMD and Intel) we will need much larger power supplies like yours. Will be interesting to see if you experience any changes in electricity costs 🙂

Have a good week!

Seriously doubt it. A 1200 watt PSU will be hovering around the middle of the power consumption band, maybe lower, he won't be using all those watts, he will probably be in the most efficient range.

How is larger PSU`s more efficient, the industry make more efficient CPU`s smaller die then the gamer want`s more performance and OC pushes the power to the CPU. How long before 2000wat PSU`s become more needed and systems are pulling 800-900w, so much for the planet green credentials of the PC, how long before the government`s stop manufactures from allowing OC CPU`s cap the power of PC`s.

They Aren't. Modern PSU's are these days regardless of wattage. I was just pointing out that with such a big wattage, his system is unlikely to be pushing the limits re wattage and thus be close to the middle of the power band were all modern PSU's are efficient.

Even at the limit they are pretty efficient these days. 

Below is a 1000 watt EVGA. You can see that peak efficiency is usually around the middle.

like "80 Plus Titanium" will be more efficient and actually use less power from the source

 

Certainly will.  Even Titanium or Platinum doesn't make a huge difference though. I didn't even bother for my new build, was quite happy with Gold, especially as PSU's were in short supply at the time. Have had Platinum ands Titanium in the past and didn't notice any difference in bills. 

I remember Jonny Guru the PSU expert who know works for Corsair, commenting a while back how Gold V Titanium is just a few dollars a year saving for most people.

Any ideas?

One possibility is that if your old PC was not HT enabled but if the new PC is SMT enabled then without an appropriate Affinity Mask the main P3D task could be sharing up to 40% extra load on the second virtual core. So I would check that by either; switching off SMT in the motherboard settings or by applying an AffiinityMask in Prepar3D.cfg to exclude the second Virtual Core.

So I didn't think about it at the time but I have always disabled hyperthreading as I saw better results with it off on my intel cpus. I have now disabled SMT, and I will see if there is any noticeable difference. Thanks.

So this is the cpu with SMT off. FPS still not great. Never really goes above 4.5 ghz. Here are some pictures from about 6000 feet above orbx newcastle in the rain.
