Reducing MoBo Power strain

[Emo_Otaku]

After an unfortunate coffee incident I recently upgraded my keyboard to a corsair k70 (Oh Faithful Logitech G15 I still miss you )

 

In the last couple of days my machine died (I think its probably the graphics card and am waiting till the weekend to troubleshoot using a spare card, otherwise upgrade time Woo hoo)

 

However it got me thinking the new Keyboard with its 100+ leds lit up all the time could this be an unnecessary strain on the Motherboards USB power delivery?

 

Am I going to be better off plugging My Keyboard/mouse/ etc into an externally powered USB hub then into the main computer

 

But would this introduce control lag when gaming (a millisecond here a millisecond there, it all adds up and soon I may as well be using a console)

 

What are peoples thought in this?

 

Is this a good Idea, or proof My Mother did drop me on my head when i was a baby?

each led uses .something mA so not really, no need to power externaly, external power  wouldnt bring any lag, no logic board or any processing in the hub is done,
