Closer Look: DZ78KLT-75K
Intel doesn’t push any boundaries in their ATX motherboard layout; everything’s where you’d expect it to be. There are a few items of note, though: the first is the inclusion of a single PCI slot in position 6. Since the Z87 chipset no longer supports PCI, Intel uses an ITE Tech 8892E PCI-E to PCI bridge chip. There are six four-pin PWM fan headers, and Intel flags them all in bright red.
The ATX main power connector is in its expected place, with on-board Power and Reset buttons nearby. Just above these buttons is a small audio transducer, a feature I really like to see on a board since it means you don’t have to dangle some little speaker from the front panel header to hear the POST beeps.
Moving to the left reveals a blue USB 3.0 header, then the 8 SATA ports. The six blue ports are 6G ports from the Z87 chipset, while the two gray ports are 3G ports.
The slot layout comprises three PCI-E 16x slots and three PCI-E 1x slots, along with a single PCI slot. Giant skull motifs notwithstanding, a lot of Intel boards go into business and OEM systems, so perhaps the inclusion of the PCI slot is understandable.
From left to right, the I/O panel has a PS/2 mouse-keyboard combo port, two (yellow) USB 2.0 ports, the Back to BIOS button, a FireWire 800 port, two gigabit Ethernet ports, six USB 3.0 ports, a DisplayPort video output, and analog audio panel with an optical audio out port, and a single Thunderbolt port. The yellow USB ports support high-amperage charging for tablets and other devices.
Let’s take a look at the details of this board in the next section.
