GTX 650 ti TDP question

Last response: in Graphics & Displays
Share

So i`m about to buy a GTX 650 or 650 ti. I`m currently running a gt 440 my question is about the 650 ti`s tdp. The non ti version has a 64w tdp (1 watt lower than my current gpu) and the Ti version has a max tdp of 110w. I know my computer can handle the non ti version but for 30$ and extra performance i rather buy the ti version if my computer can handle it.

These are my pc specs:
Intel Core 2 Duo 2.8 Ghz
3G Ram (i will upgrade to 4g)
Windows 7 32 bit (i will upgrade to 64)
400w Antec PSU


CPU-Z (cpuid) says my CPU has a max tdp of 65w i was wondering if that is the max tdp i can run on a gpu or is it not relevant? Any help or information you provide is appreciate it.

I don't see a reason why not. Both cards need a single 6 pin PCIE power cable cable. As long as your PSU has that then power wont be an issue.

You will probably get a restriction in Max FPS with your CPU but for $30 extra I would take a punt.
As long as you are using a reasonable resolution 1920 X 1080 would be good here, then I don't see why you shouldn't get a really nice performance boost from the 650Ti.

Mactronix :) 

My PSU has that 6 pin connector just hanging out with nothing to do. I`m just concerned with the GPU MAX TDP i wouldnt want it to over heat on my cpu. I`m still not fully knowledgeable with TDP and all that stuff. I was thinking on upgrading my gpu to a 500w or a 450 just in case. Oh and yes i`m running a 23 `in LED monitor 1080p.

Antec makes good quality PSUs. It's more than enough if it's for gaming.

GTX 650 Ti running Batman: Arkham City (1080p) only 140 Watts of system power consumption: http://hexus.net/tech/reviews/graphics/46349-nvidia-gef...
It says: "System builders will be able to use 400W PSUs... with some capacity to spare, going by our results."

Here running Unigine Heaven Benchmark (2,560 x 1,600, default settings) only 166 Watts: http://www.bit-tech.net/hardware/graphics/2012/10/09/nv...

I have a 300W PSU and planning on buying an MSI GTX 660 for my setup.

Yes its for gaming, So 300 watts for the 660? dont you need more than that since you are running your motherboard and other components as well?

Watch this Youtube video: http://www.youtube.com/watch?v=toPSItZ7MII
Fast forward to the 7:20 minute mark.

I have exactly the same 300W PSU in the video. It wasn't able to power a GTX 560 ti. Howerever, it was able to power a GTX 560 non ti, and that's running prime95 and Furmark.

GTX 660's TDP is 10W lower than a 560. So, a 660 will run in my setup. I have an i3 BTW.

Read this article on how little wattage entry level PC setups actually need.

Thats awesome and thanks for the article i mean i knew they usually say to get more watts than its actually need it as a just in case scenario, the card i`m getting is a Ti i hope my 400w is enough.
