Issues with GTX 560 Ti. [Bad Performance]

[jbrown99]

I'm getting very poor performance with this card. I upgraded from a GTX 550 Ti and with some games I feel like it had better frame rates than this new one does. My friend with an i5 processor (I have an i7) and a 550 Ti gets almost double my framerate with ARMA: II.

Here are my specs:

CPU: Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz, 3411 MHz

GPU: NVIDIA GeForce GTX 560 Ti

PSU: 400w Power Adapter (Native)

Memory: 8GB

Monitor: Dual. Primary is 1600x900, secondary is 1280x900.

I'm not sure what else to include here. PLEASE HELP!

Well that 560 Ti needs 210W .So what is the model of that PSU ? Amps / W on 12 V rail?

 

[jbrown99]

It came with the computer, so all I know is that it is 400w.

Well open the case and read it.

You need to investigate more. The 560 TI is a great GPU.

400W is VERY low for a PSU. It should be at least 500W. That might be the culprit. Give your GPU to your friend and see what he gets.

Agreed, the 560Ti is a somewhat power hungry card, and some cheap off-brand 400 watt power supply that comes with some computer cases will not be sufficient to power it. Even high quality 400 watt units would be pushed to the limit with a 560Ti.

So when I upgrade the PSU, will my FPS raise tremendously? I didn't know a PSU could bottleneck it that much.

Well it dsnt get power. So it cant work

 

[envy14tpe]

Yes, it can bottleneck it. It is recommended to have a 500W PSU for a 560ti. In reality, the number might be 450W or less, but if you follow the recommended power needed you won't have any problems. Also, get at least a Bronze Certified PSU. It wastes less power.
The first choice is Bronze, the second is cheaper.
