Tech Inferno Fan Posted April 14, 2015 Share Posted April 14, 2015 2014 Mini requires special EFI card to show boot screens and display support in OSX with Nvidia cards.For Windows I find the EFI isn't needed.Here is a 3D Mark score with Titan-XNVIDIA GTX TITAN X video card benchmark result - Intel Core i5 4350U,Apple Inc. Mac-35C5E08120C7EEAF NVIDIA GTX TITAN X video card benchmark result - Intel Core i5 4350U,Apple Inc. Mac-35C5E08120C7EEAFStrange 3dmark11 result there. My OCed GTX970 is beating your Titan-X when it should be ~25% faster per NVIDIA GeForce Titan X 12 GB Review | techPowerUp . When not overclocked my GTX970 was getting ~12.6k for 3dmark11.gpu which is still faster than your result.

MVC Posted April 14, 2015 Share Posted April 14, 2015 Yeah, not sure why. It is connected to a 4K 60Hz display so pushing lots of pixels. I'll try with a 24" Dell and see if that changes anything. Also consider that this is entry level Mini with 1.4 GHZ CPU Quote Link to comment Share on other sites More sharing options...

Cignium Posted April 17, 2015 Share Posted April 17, 2015 I read it, but it isn't what i'm looking for. I want these: Using under Windows: The video card can display an image on an external monitor or on the internal screen. To operate on the internal screen output, the configuration of your Mac must be equipped with only a video card Intel (Intel HD 4000 and above, Intel Iris, Intel Iris Pro). If you have two video cards, this function will not work. For output to an external monitor, any combination (Intel, AMD, NVIDIA, Intel + NVIDIA, Intel + AMD). So it says that it can't do what i want if i have iGPU. Quote Link to comment Share on other sites More sharing options...
errin Posted April 18, 2015 Share Posted April 18, 2015 Not sure if this can help. I have non-Retina 2012. I can use both internal and external at the same time. The internal use 650m and external use eGPU. Quote Link to comment Share on other sites More sharing options...

Only recently we had the AKiTiO 25W slot power specification demystified. Prior to we had many users reverting to powered risers to increase power, as that link shows, which actually degrade the PCIe signal.

[solved] - Graphics Cards - Graphics CardsAs I understand the user pcgaming98 is saying that 12V railed power supplies (like the one you linked on eBay) do not provide enough Amps to run a GPU. What do you think about this?Yes, with the additional 120W PSU you can run a 750Ti that comes without an additional 6-Pin PCIe Power connector.Are you sure there wouldn't be amp problems like the forum post on Toms hardware says?Also the GTX750Ti apparently requires 300W though it says that it only draws 60W. Can you clarify this for me? It's all quite new!Interesting that user johndshea almost got it working in the thread you linked though.

The AKiTiO needs about 10W to drive the TB circuitry,so you're looking at 76W peak loadjohndshea would have had instability due to overdriving the supplied 60W AC adapter.

Apologies if its a stupid question.Those 300W figures are powering a whole system so make little sense in our case where we are just powering the video card + TB board. I've already specified a cost effective TB2 enclosure + 120W AC adapter to power a GTX750TI (without PCIe power connectors). No power or amperage issue so long as the 120W AC adapter is a quality item delivering upon it's specs. Quote Link to comment Share on other sites More sharing options...
Dschijn Posted April 18, 2015 Share Posted April 18, 2015 The card is specs are 300W to power a whole PC with that card and it's rated to 300W to be able to provide enough power for the card on the 12V rail. As long as you don't overclock the card way too much, you will never exeed the 75W of the slot by any time (maybe short peaks). So the 120W PSU is just a very safe way to go Quote Link to comment Share on other sites More sharing options...
