Will a seasonic prime 850w gold be enough for the 3960x?

hi guys!

i bought the components for my new build, and i thought i was going with the 3950x, but then i saw the performance of the 3960x and changed it around.

i already have the seasonic prime 850w gold PSU mounted in my case, and hoped this would be enough with x 2 SSD's and a founders edition Nvidia 2080 GTI.

Any thoughts on this?

At stock it draws somewhere in the 286 W range, so It should be fine for that.  However, when overclocked to high all core speeds, this can go up dramatically.  The 2990WX 32 core from last gen got a bad rap for being 250 W but this was actually quite reasonable - when pushed to 4+ GHz on all cores, it would hit ~600 W, so if that is your plan, you will probably want a larger PSU as well as an ungodly amazing cooling system.

Yes, even if both CPU and GPU are under stress test. 3960X, being a 24 core CPU, will draw roughly (actually less than) 3 times the 8 core 3700x which draws about 120w. 250w to a stock 2080Ti or 320w if you go with max limit of the card. SSDs, fans, cooling system and board can stuff might take 100w-150w extra depending on what exactly you choose, but there's definitely room.

It would be great if people can stop giving their own names to existing products though

thanks a bunch!

 

no plans of any sort of OC here.

I'm curious to see how hot it runs!

I have my rig 2x Xeon E5-2667 v3 (135 W TDP per CPU) with 8x 4 GB DDR4, RTX 2080 Super, 6x SSD RAID-0 and one HDD for backup. The power supply is Seasonic Prime Ultra 850W Titanium.

 

I tried to run a FLOPS bench with double precision AVX (run in command prompt) on CPUs and play an AAA title game ray-tracing at same time, it's under 600 W load (my APC Back-UPS Pro 1200 said it). It works fine.

 

And all frequencies are stocks.

Me, thinking this was a thread about X79 but then being reminded that AMD gave their CPU the exact same name an i7 already had:
