If you have bought our Type R MK II series power supplies (the ones that has USB ports at the back of PSU) you will probably encounter this issue. Known effected motherboards: Asus Striker Extreme, ASUS Blitz Formula SE, ASUS M2N32 SLI Deluxe, Asus Crosshair, Gigabyte GA-X38-DS4, Gigabyte P35C-DS3R, MSI K9N Neo V3 and Abit IP35 Pro.
Type R MK II series power supplies consist of USB module that required an USB cable to be attached on the motherboard. The reason could be the USB module of the PSU is conflicting with the motherboard's +5VSB power. HIPER has already fixed the problem in the current productions. For customer who bought the PSU earlier, the following is a little DIY that should fix the problem:
Loosen the fastener by a clip and pull out the red wire.
Insert the red wire to the empty slot (from slot 1 to 5).
Note: Removing the red wire will NOT effect the power on each USB port since the USB module is directly powered by the PSU, i.e. each USB port is still fully powered.
