Hi people! I just wanted to share my gGPU setup with you and talk about the benefits and problems. I bought the Akitio along with a passive Palit GTX 750 TI because I didn't want my gGPU to make any noise nor to need any extra power supply. The Maxwell GTX 750 ti does all that since it only draws 60W and like this, I just needed to apply the guide (here) to pass up to 75 W through the PCIe port so that I could make the most compact setup possible (with a passive GPU). I even got to make it work under OS X and Windows stable, although on Windows I didn't activate optimus with the internal screen of my 13" rMBPr Late 2013. The setup works very stable in idle and whenever I really push it hard, I just put a little 6cm NB-Fan in Front of the GPU which it cools down to less than 60 degrees on 100 % load without any noise. My only problem now is, that there shouldn't be any noise, but yesterday the Akitio and its PSU startet to make a buzzing noise at full load which I am not sure if it is coming from the coils of the PSU or the Enclosure itself. Anyway my main problem is now that I then found that the Akitio makes a subtle but perceivable very high frequent noise as soon as the PSU is plugged (Akitio not activated) Now my question is, could someone who ownes a Akitio check, if you can hear this noise on any Akitio or if it is just mine that has a problem. Thank you very much in advance! Regards, salut
