Possible power problem

Hello, I am currently using the Qpad MK-85 keyboard.

Over the last couple of weeks the integrated LED backlights for the keys have dimmed to almost nothing, from being overly bright when I first purchased the Keyboard.

My idea is that it's possibly a power issue?

I'm using a 700w at the moment with:

Phenom 965 on stock voltage
GTX 480 on stock voltage (was overclocked but underclocking voltage made no difference)

Other than that I have 140mm, 120mm x3 fans and then just the standard other peripherals.

Now I know the GTX 480 is power hungry and haven't had a chance to test the keyboard in another PC yet but I'm pretty sure I'm no where near close to capacity on the PSU.

So my question is that, should I be looking at a power problem or possibly an RMA of the product? I guess I will find out when I try it on another setup but is it feasible that a lack of power is going to dim keyboard LED lights while I have zero issues with desktop/gaming stability.

Thanks in advance for any input.
 
The extra load created by a few LEDs isn't going to strain your system. It's far more likely that the USB controller isn't giving full 500mA to the keyboard, which means the LEDs are starved for current.

Not quite sure how you'd fix this.
 
Thanks for the response. I'm leaning to an issue with the Keyboard after testing on 2 other systems and still getting the same issue. Reinstalled software for good measure but to no effect.

...Sods law, as I was writing to Qpad support everything lit up. So it's on hold for now, must be a dodgy connection or something :/
