Question Is my PSU enough to run with these 2 GPUs

[bmost4395]

I just found out my extra GPU that is sitting and gathering dust is a GTX 750!
I was wondering if my EVGA 600w 80+ can handle both the GTX 750 and my main GTX 1080 FE
I'm wanting to encode video using the 750
Specs
CPU: Ryzen 5 1600x
Ram: Corsair rgb pro 2666 oced to 2900
Gpu: 1080 FE
PSU: EVGA 600w 80+
Mobo: MSI gaming pro carbon z750
1 ssds and 3 hdds
May have gotten some of this wrong on phone at work
Thanks for reading and helping me out in advance

I'm struggling to figure out how a GTX 750 is going to help you encode video better. What are you going to be doing that requires video encoding? I can gurantee that the GTX 1080 will encode better, and faster. Also, your CPU is perfectly capable of encoding video quickly as well.

I see why your confused
Sorry did not add that I want to be recording with OBS
And gaming so my 1080 FE and cpu will not be dragged down by the process but instead the 750 would be doing all that work.
But what I'm doing is not the question. The question is would my PSU have enough power.

That PSU isn't a particularly good one, but yes it should be capable of powering both cards. How old is the PSU?

Been running it for a year and no more than 4 months

Yes, but... why not record with the NVENC on the 1080? Almost no framerate hit and you don't have to worry about an additional card. Sure, your PSU can handle it, but the encoding hardware on the 1080 doesn't share resources with the rendering hardware. It might work, but in order to push the data to be encoded to the 750Ti you are going to be using CPU and system bus resources that encoding with the hardware on the 1080 doesn't need to use.

My advice is to try it all ways and see what works best. If the 750Ti works best I'll eat my humble pie, but I think either other way would work better.

I just wanna use for this thing other than it laying around picking up dust haha

You could always pick up an older refurb system, toss in the 750Ti and a video capture card, and record your video that way. Absolutely zero performance hit on your main system. Although, that would be more expensive. $100-$150 or so for the refurb machine (like an older i5), then whatever a capture card costs.

Of course, low end gaming is big these days, you should be able to sell it. Then at least someone else could get some use out of it.

Just means you're lucky. 😉
