I ordered a Corsair K70 (mx blue). However, I will be using this with a laptop that only has 3 USB ports (and will be using it with external monitor/mouse/keyboard half the time). Corsair says a high current (500mA) port is needed. Can I get away with a cheap bus-powered hub anyway (particularly since I don't intend to use the backlighting much if at all), or do I need to shell out the extra for a powered one? I might also want to sync my phone through there as well. (If it charges slowly, so what?)
Note: if anyone's wondering why I can't just plug it straight into the machine, it's because I have other peripherals like a bus-powered USB 3.0 hard drive that I particularly want plugged straight into it.
