2way SLI GTX 1080TI on RM Series 750W Modular 80Plus GOLD

[Mycobacterium]

Hi, I've made several improvements today to my desktop configuration.

Instead of changing the platform, I added some hardware.

Starting from the beginning, my current configuration is:

 

i7-4790K on MSI Z97 MpowerMAX AC with 16GB G.SKILL DDR3 TridentX and MSI Nvidia GTX 1080TI 11GB

 

I thought about changing motherboard with CPU, but the current CPU works very well and its performance can shame lot of new platforms.

So I bought today another MSI Nvidia GTX 1080TI 11GB with another 16GB G.SKILL DDR3 TridentX.

 

Can you tell me if the RM Series 750W Modular 80Plus GOLD will make it with this configuration?

 

[Firewrath9]

yeah, but if you are going to OC both, then I would recommend a larger PSU. 

[Mycobacterium]

Thanks, no, OC is not necessary for that kind of config

Lol well, as you won’t be able to use both cards and the cpu at the same time, you’ll be fine with 750. 

 

Unless youre doing some kind of fancy editing/rendering. 

[Mycobacterium]

You sure about that ?

Well If you are gonna play the two games shown in the video at that resolution, you may be ok. 

 

Aside from that, I’ll put money on it. That cpu isn’t keeping up with them.

What resolution are you gaming at?

That video is absolutely awful. It tries to benchmark CPU performance by playing games at 7680x1440 - where you will be heavily GPU limited. That's about 25% more pixels than 4k. Yet, even with the demand being heavily on the GPU, the 4790k is still shown to be unable to keep up.

 

You can see the CPU usage is at 90% while the GPU usage has slowed to 54-68%. Meanwhile both the 7700k and 8700k tests have 100% GPU usage and aren't being bottle necked by the CPU. The 4790k is bottlenecking at 7680x1440.

 

You probably should have invested the money in to a platform upgrade instead.

...and there is the SLI Problem, wich can cause Problems in some games and in others it just does not work...

From 2560x1440 to 4K

I think this change is future-proof, it will change the CPU in the future.
After the new year interesting titles are to come out, so I'll wait.

 

4790k is bottlenecking at 7680x1440 so lower res are ok for this CPU and SLI ?

[Mick Naughty]

lol

In most games with very high graphical settings a single 1080Ti is fine for 1440p at 144+fps and 4k at 60+fps...

Also 32GB of RAM is pointless if you're not doing productivity workloads. 16GB is enough for gaming and you don't really see any performance boost by having more.

Did you buy the RAM and 1080ti new from a store or 2nd hand? Are you able to return them to the store for a refund or if bought second hand able to sell them for close to what you paid for them?

I watched 2 LTT videos and what made me laugh still was the Forums, gotta love this place.

A CPU bottleneck will be worse at lower resolutions, not better.

[Mycobacterium]

Wait a moment

 

I do not want to give anything back.

 

This setup will be expanded in the future.

 

Better Motherboard, better CPU, DDR4 memory, better screen, so even if I do not use this potential in 100% now, I use it later

Well I work with some data and VMware (gitlabCI, kafka, ELK, redis, memcache, docker) so 32GB is absolute minimum for me for my home lab PC

Yep, but only for a few seconds 

 

It's not so bad

Bf1 single player? Well no one would really care about performance limitations there.
