Hm ... $20? Really necessary?
EVGA released what it claims to be a handy little accessory that can increase PCI-Express slot power, improving overclocking stability of graphics cards installed. Called the EVGA Power Boost, the gadget is a tiny PCB that fits into the power-line notch of any PCI-Express slot (x1 thru x16), and draws in an auxiliary 12V line directly from the power supply unit. The little PCB draws in power from a standard Molex power connector, adding it to the motherboard's 12V line. EVGA also gave out a detailed HD video showing users exactly how to install the device, because inserting it into the wrong part of the PCI-Express slot will fry the motherboard. EVGA is asking $20 for it.
