[SOLVED] Seasonic Focus 850W Platinum

[masterviper]

Hey All,

I got my hands on this one recently from BestBuy and plan to pick it up once its ready.

Will this be a good enough power supply to handle an I7 10700K Overclocked to 5Ghz, 32GB memory, 1TB PCIE with two 4TB HDDs and a 3080 card?

My current build has the same specs except for the GPU which is currently a 1070 and the two 4TB HDDs are not installed. I'm currently using a nearly 7 year old Corsair AX860i

It should be.
NVidia recommends 750W and I think they tend to be a bit high sometimes.

I'd think worst-case CPU would be 220 watts (I have a 10700K OC @ 4.8Ghz all-core - it runs 145 watts @ 100% CPU). Say the 3080 runs 380 watts (again, a fairly high number). You would be at 600 watts. Add 100-120 watts for fans, SSD, HDD, etc. (another high number when your read specs) and you're at 720 watts. I also have a 3950X with 2070 Super with water cooling and 6 fans and have measured system power usage with a meter from the wall - I've never approached 700 watts in sustained, benchmark usage.

I suspect if you measure actual power to your platform from the wall, you'll typically be in the 650-700 watt range...in any case, fine with a high-quality Seasonic 850 watt PSU (all of my PSUs are Seasonic).

What's wrong with your AX860i? If there is nothing wrong with it I'd rather keep it. 7 years isn't old yet for something nicely built like that PSU.
