Last year I built a "Hackintosh" Mini-ITX computer containing a Gigabyte GA-H87-WIFI motherboard and an Intel Core i7-4770K quad-core CPU. The power supply in this computer is rated at 180 watts. The 4770K CPU contains on-board Intel HD4600 graphics. If I run this configuration on the Unigine "Heaven" benchmark, it returns a result of 12.4 frames per second. If I install my EVGA GT610 graphics card in the PCIe 3.0 slot and run the computer with it, "Heaven" returns only 4.5 frames per second.
 
Is this normal? I am constrained to use the GT610 because of the maximum length allowed of a graphics card in this small case. According to the "eXtreme Power Supply Calculator," with the graphics card in, the minimum power required is 181 watts. With it out, the minimum power required is 159 watts.
Other details: 16 GB Kingston RAM, Samsung 840 EVO 250 GB SSD, running Mac OS X 10.10.3 "Yosemite," Gigabyte BIOS version F8.
 
What am I missing? Is the driver supplied with the card not adequate for this card in this computer? Is the HD4600 just that much faster than the GT610? or what?
 
Thanks for reading!

wstrohm? Is the HD4600 just that much faster than the GT610? or what?

Yes!. Much!.

"You should be able to fit a GTX650 in the same space as a 610. That will give much better performance."
 
Better performance, yes. Fit, yes. But power requirement, no. EVGA says 400 watts minimum, and my power supply is only 180 watts. The "eXtreme Power Supply Calculator" says I need 166 watts minimum, 216 watts recommended for my exact configuration. So since I have 180 watts, should I go by that and buy a GTX 650, or forget it based on EVGA's requirement? And if I do get a GTX650, what kind of performance improvement should I expect?
 

Why not get a new Power Supply?
EVGA SuperNOVA 550 GS Power Supply and even has the ECO Mode for Less Than $90.

"Why not get a new Power Supply?"  Dimensions of your linked supply are 86mm (3.39") x 150 mm (5.9") x 150 mm. Although relatively small for a power supply, 540 watts is major overkill, and also would not fit inside the Mini-ITX case.
 
This is a simple choice: Believe EVGA and do not install a GTX650, or believe the eXtreme Power Supply Calculator website and install the GTX650.

Sorry your link is not working, I would then use the HD4600 Video.

Built  in 180W PSU, this is small for sure.
I would pick the biggest GPU you can find that has No Power Connector on it.
Off Hand I cannot find a single that uses less than 300 Watts.
Even the GT610 needs 300 Watts

"An easier, if nasty, question is: Who's lying?"
I would say that they are EVGA Cards so EVGA is not lying that is the specifications come from EVGA and Not From eXtreme.
The eXtreme Power Calculator is just that eXtreme.
4.5 fps is not so bad as it is not really a Gamming Card.

OK, I appreciate your inputs; thanks for answering!

You are welcome.

I always though of the X10 and X20 cards to be for systems that need something to attach a monitor and don't have intergrated graphics of any kind.
 
As for power usage, it can depend on a number of factors, such as the rest of your system, and quality of power supply (and if the rating is peak or continuous)
 
In any case I'd recommend getting a beefer Power supply, you have a number of very good parts there, but the power supply is minimal all things considered along with a GTX 650 or better, as the 4770k is a pretty good CPU, it "needs" (sort of) other parts around it that are of roughly equal power, lest you be driving a $1000 car with $800 wheels.

The OP has a Mini Computer Case with a Built in PSU and it cannot be upgraded.

Yes, http://www.evga.com/Products/ProductList.aspx?type=0&family=GeForce+700+Series+Family most all will work or should work in your computer. Do you carry around your computer or is it stationary? All you can really do is test and if it work it works.
EVGA GeForce GT 740 2GB or EVGA GeForce GT 740 4GB Superclocked (Single Slot) look good. Both are also in stock on Amazon.

Installed the GT740 today. Found the required nVidia driver for the Mac and installed it. Using the GT740, I now get the following result on the Heaven benchmark. Very happy here! (Remember, the Intel HD4600 on-board graphics resulted in 12.4 fps.) Ran the "Intel Power Gadget" and the CPU load is less than 20 watts.

Fine, Fettle, here are the older results FYI.
 
GT 610: left pic; Integrated Graphics HD4600 middle pic; GT 740 right pic.
 
 

Look again.

I would disable the Intergraded Video in you Bios to one save on Power and two to release the memory.
Also if your Bios has a Multi GPU settings Disable it.
That is a Nice Card, glad you are working well now.

Well that was pretty clear. 740 is better than GT 610 and Intel's offering.
 
Then again you haven't shown us the results of HD 4600. Only words.

You seem to be a little rude here Fettle. This is not helping anyone.
