Legit Reviews writes MSI uploaded a teaser video for what appear to be the Z87 XPower, a new motherboard dedicated to overclocking.
The board was not shown, but could the company be building buzz for the Z87 XPower motherboard? The folks over at LAB501 grabbed a shot of an MSI Z87 board at Haswell that is shown below. Some think that this could be the Z87 XPower board since it had two 8-pin EPS connectors and a 16-phase VRM design. The blue connector by the 24-pin ATX power header is also unknown.
