[SOLVED] Power supply advice for my system - Seasonic?

[joedickenson]

Hi,

The below build I do some gaming and alot of work in 3D. I have a feeling the PSU I currently have isn't man enough for what im doing (I built a new build early January only thing I didn't replace was the PSU ! May also want to overclock.

Build:

gigabyte aurous x399 xtreme motherboard
Amd threadripper 1920x
Aurous 1080ti
Corsair vengeance 3466mhz pro RGB 32gb (will be moving up to 64 at some point)
M.2 Samsung drive (and 5 other hardrives ranging from hdd to sdd

I was looking at the seasonic focus gold 1000 watt. Will this do the job ?

Thanks for any help

Joe

That psu is top quality and will do the job.
Actually, it is overkill; something like 750w should be plenty.

I have no problem overprovisioning a PSU a bit.
A PSU will only use the wattage demanded of it, regardless of it's max capability.

Hi thanks for the reply!

Will this be plenty for adding things in the future say if I wanted to get a 2080ti or something? I don't really know how the PSU works etc so I'm lost in that regards! I need to be able to draw slot if power when needed as when I create particle effects etc with in 3D programs or will draw slot if power!

Would a 850w be more than enough do you think?

Id like to have more than enough and not be worried am I pushing it to hard etc

Kind regards

This psu sizing chart has been very useful to me:

The main use for power is the graphics card, followed by the processor.
All of the other components are of relatively minor nature.

A Future RTX2080ti upgrade might well have no problem with even a 650w psu.
The power used by a RTX2080ti will come from two 9 pin connectors at 150w each and 75w from the max slot power, totaling 375w.
What I do not know is how much power your threadripper processor can consume under load.
The default TDP of your 1920x is 180w the stronger units have a TDP of 250w.

Hard drives may be 10w.

The only real negative to overprovisioning the psu is cost.
750w might be $100, 850w $130, 1000w $150

For the $50 difference in a top end build, you will feel better with the 1000w unit.

What parts do you now have?
I am assuming you have it all except the psu.

If you have not yet bought, look at the intel i9-9900K which will be a better gamer.
You may find that the 16 faster threads will do better in multithreaded tasks than the 24 slower threads of the threadripper.
Look for benchmarks of the apps you will be using.

A caveat on ram:
Ram is sold in kits for a reason.
A motherboard must manage all the ram using the same specs of voltage, cas and speed.
The internal workings are designed for the capacity of the kit.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards, can be very sensitive to this.
This is more difficult when more sticks are involved.
That is why ram vendors will NOT support ram that is not bought in one kit.
Ryzen is sensitive to ram, verify compatibility using the motherboard qvl list.

If you need 64gb of ram, it is better to buy a single kit up front.
Otherwise, be prepared to sell your old 32gb kit and buy a 64gb replacement.
