First build in 15 years, and I have a GTX 690 that will be used with Maya and a GPU-accelerated renderer that can take advantage of multiple GPUs. I haven’t decided on which renderer. In any case, my thought was to have a Titan in addition to the 690. Right away, though, I realized that the two leads from the PSU are already used for the 690. My question is, is there any way to have a Titan in there in addition to the 690? If so, what will I need to do?
I have a Titan, I like it, I would not recommend it over a 780ti unless you really, really want the 6GB. Food for thought.
They will work fine together in most scenario, certainly they will if you split work/display and GPU rendering.
Power wise you’ll be fine, the 690 can draw a hard spike of 330, the titan is rated at 250 but it’s unheard of of it spiking even just a 240, both together are unlikely to be more than 500 sustained draw even taxed, that leaves your 1050W 80% rated PSU with 300W to spare for the rest, which is plenty, and the HX is a single rail so it can take any combination of loads well enough.
Temperatures are going to be your main issue, the 690 and Titan run hot by design, you’ll have half a KW of boiling water to cool off in there, so make sure you have decent flow.
