How much power supply need for this config....

[Shri Kant Morey]

Hi,

So I m a VFx grooming artist, and planing to build a PC with below given Config:

Cabinet: Cooler Master Cosmos II Ultra/Full Tower Asus ROG Maximus XII Extreme Intel Z490 EATX Intel Core i9 10900K

Nvidia RTX 3080 (not release yet) Corsair Dominator Platinum Series 32 GB Going to upgrade additional 32GBs after some time. MasterLiquid 240 CPU Samsung 970 EVO Plus 1TB Seagate Firecuda Gaming SSDH 2TB   All i stuck here with how much power supply i need for this? I add a "Cooler Master Vanguard 1000W" but i thing this is to high power for this. And Is all parts are supportable to each other?   I m also gonna use this for cg rendering, gaming and other kinnda stuff like fx propose.   Thanks, all comment are acceptable here.

You'd be fine with a 650W, but I think going with a 750W wouldn't be unreasonable at all depending on how much you plan on overclocking that 10900K.

Something like an RM750x, Straight Power 11 750W or Ion+ 760W should do fine in there.

 

Kind of off topic, you don't need to spend that much on the motherboard. Unless you're going LN2 overclocking (which you're not), that's a waste of money.

750w+.

i'd go with 750. 

a 10900k draws 200W

a 3080 has a tdp of 320W, but may go higher if overclocked.

the rest of the system, max 100w

Thanks Man, That really helpful, also the second idea is good for me.

If you want a board that'll handle everything you can throw at it, I'd suggest going with a Z490 Unify. I'm not sure exactly what the Maximus XII Extreme is priced at, but I know the Unify's cheaper than even the Hero.

 

Do note that the Unify doesn't have iGPU power if you were planning on using that for QSV or whatever, but neither does the Extreme so I guess that's not really an issue.

Sure, Z490 Unify price is aprox half from Maximus XII Extreme here, Z490 Unify work for me same as Extreme, and that also save some money for me to other additional things that i wanna add on rig

Nvidia says 750W so that would be the min for your system and it may be fine if everything is ran at 100% dead stock out of the box...  

 

Personally I would recommend getting a 850W PSU to give you some room for future upgrades and or overclocks. (IE: A lot more power draw)

 

Something like a Corsair RMX or RMI 850W as an example or HX, HXI 850W. 

 

You may find the 750W on the light side if you start pushing both the CPU and GPU at the same time doing your CG work etc putting your PSU into that 85% or higher load range.. CPU at 300W+ and GPU at 400W.... Could put you over 750W if pushing both at the time....Total system power draw...

 

Something to think about anyway.

 

If it was my system I wouldn't get anything less than a 850W PSU and likely end up with a 1000W to get me into that 70% or less power draw range....

 

 

In the end it does matter how you plan on running the system, whether you tweak the settings or not for the GPU and CPU. The power draw can and will vary a lot depending on what you actually do. 

 

So....

 

100% dead stock with no overclocks or tweaking on the GPU and CPU.... 750W PSU...

 

Tweaking/ Overclocking on the CPU and or GPU....... 850W or 1000W...

 

 

As a side note, I couldn't run a 650W PSU on my system below as it would cause the PSU to shut down if I really pushed it. Say 5.1 or 5.2 GHz on the CPU and OCed the GPU power draw on MY system would be over 700W easy ...... The power draw is more than 660W as I run it NOW....
