TPU came across photos of the Zotac ZT-Z77-U1D SuperOverclock, an upcoming Z77 motherboard aimed at overclockers. The board features 27-phase VRM with VRD12-compliant controller, AIO ferrite-core solid-state chokes, DrMOS, tantalum capacitors, and a super-MK multiphase capacitor to condition power. Pricing and availability is unknown.
The LGA1155 socket is wired to four DDR3 DIMM slots, supporting dual-channel DDR3-2133+ MHz memory, and two PCI-Express 3.0 x16 slots (x8/x8, when both are populated). Other expansion slots include four PCI-Express 2.0 x1, wired to the Z77 PCH. All six SATA ports from the PCH are assigned as internal ports, that's two SATA 6 Gb/s, and four SATA 3 Gb/s. Display connectivity includes DVI, HDMI, and DisplayPort. Other connectivity includes 8+2 channel HD audio, 802.11 b/g/n, Bluetooth 3.0, gigabit Ethernet, six USB 3.0 ports (two on the rear panel, four via headers), and a number of USB 2.0 ports.
There are several features for overclockers, including redundant UEFI BIOS, consolidated voltage measurement points, onboard switches, POST LEDs, and a spacious upper half, with very few cylindrical capacitors to obstruct LN2 pots. Apart from 24-pin ATX, the board draws power from one 8-pin EPS, and one 4-pin Molex (optional, only if there are two slot-powered graphics cards).
