I currently have a SeaSonic PRIME Gold 1200W
I purchased it for a 6-GPU mining rig, which I no longer have.
So, I've been using it as my main PSU.
10% load efficiency is 87%, but 10% load is 120W.
My system idles at 70-90W. So it would be less than 87% efficiency, likely close to 86%.
Since I mainly use my PC for web browsing and homework more than I do gaming, I'm thinking about buying a more efficient PSU to save money on energy cost in the long run.
I'm looking at the PRIME Titanium 650W, which has a 91%+ efficiency at 10% load.
System:
i7-7700K
GTX 1070 SC
16GB DDR4
2xSSD
2xHDD
4x120mm fans
Gaming Keyboard, mouse, headphones, controller.
System power under gaming load = 270W-290W.
What do you think about selling the 1200W Gold and buying the 650W Titanium? It would likely work out to an even trade after Ebay/Paypal tax + shipping. I can get the 650W Titanium for $137.99 on sale right now.
Would anyone even buy the 1200W unit?
In a typical weekend my system idles for 10-12hrs/day and games for 2hrs/day. During the week idles for 4-6hrs/day and games 1hr/day. So I have a lot more idle time than gaming time.
