Hello, I recently acquired a Logitech Hyperion Fury Optical Gaming Mouse, and all of a sudden my BlueFinger keyboard won't function under high load (LED is still lit, buttons don't work) while the mouse is plugged in.

Computer breakdown:
CM Storm Stryker case
Windows 8.1 OS
Inside the Computer:
Corsair Builder Series 500W ATX12V PSU
Gigabyte 990FXA-UD3 motherboard
AMD Phenom II x4 955 3.2Ghz CPU, fits AM3 socket
Samsung 850 EVO 500 GB SSD
1.5TB 7200 RPM SATA HDD
2x G.Skill Ripjaw Series 240pin 4GB DDR3 SDRAM
Nvidia GeForce GTX 550 Ti GPU
TP-LINK TL-WDN4800 Wireless Adapter, PCIe x1
Be Quiet! Pure Rock CPU Cooler(includes 120 mm 4-pin PWM fan)
DVD-RW/DVD+RW Drive
Replaced the stock 200mm case fan with an LED one, all other fans kept
Outside of Computer:
BlueFinger LED keyboard by UThink (cannot for the life of me find their website)
Logitech Hyperion Fury G402 910-004069 Mouse
Sades 7.1CH Gaming Headset
Ethernet connection

Any time the computer is under high load (tested with World of Warcraft, Starcraft II, GTA V, Dark Souls 2), the keyboard ceases to function with the mouse plugged in, but will resume function without anything high-load open. It previously worked fine with the paired mouse that came with it and works with another mid-range LED mouse I had.
I calculated the power consumption of this build came up with 425 W 100% load, so it shouldn't be a power problem, unless my calculations are off (provide a dependable calculator if you have it and do your own calculation if need be).
As stated previously, I am unable to find the product website for the keyboard (it's Chinese, so no surprise there) and Logitech does not have this issue apparent on their support page. Basically I cannot fathom what the problem could be other than power shortage (that would be weird, considering that the keyboard stays lit), which I hope is not the case.

Have you tried plugging the keyboard / both KB and mouse to the USB 3.0 ports?Those supply more current than the normal 2.0 ports. Do you have them connected through a USB hub or directly to the motherboard?

What PSU (manufacturer and model) do you have?
Have you tried disconnecting yuor headphones and testing with no hardware externally connected other than the keyboard and mouse , each to its respective USB 3.0 port?

Corsair Builder Series 500W ATX12V, sorry about putting 550W, got mixed up with my 550Ti GPU. Both keyboard and mouse are and always have been plugged into the two USB 3.0 ports on the I/O panel.

Good NEWS everyone! Turns out everything works when the mouse is in a USB 2.0 port. I guess that's as solved as it gets. bluefinger.com is not the product website. Bluefinger is the model and Uthink is the company (Uthink brand labeling on the keyboard), I just can't find their information anywhere.
