More Intel Desktop Board Media Series Motherboards Pictured
Intel activated product pages of nearly all its upcoming Desktop Board products based on 7-series chipsets. Last week, we were treated to detailed pictures of Intel's Z77 chipset-based Desktop Board products. Now we move on to other Desktop Board Media Series motherboards, those based on Intel's other 7-series client chipset the H77. Pin-compatible with Z77, Intel's H77 chipset provides nearly all features of its sibling, with the exception of overclocking. So motherboard designers needn't dedicate resources to implementing strong VRM designs on their H77 products, and can instead focus on other features such as connectivity and expansion.
Intel's H77 Desktop Board Media series includes the DH77KC (ATX form-factor), DH77EB (micro-ATX), and DH77DF (mini-ITX). The DH77KC shares its PCB design with the Z77-based DZ77SL-50K. Its CPU VRM has one phase less, and does away with the VRM heatsink. Display connectivity is expanded, with the addition of DVI and DisplayPort connectors. An mSATA slot is added to the mix, something not found on the DZ77SL-50K. Also added are some legacy port headers, such as LPT and COM.
Next up, is the DH77EB micro-ATX board. Thanks to some clever designing, this 240x240 mm board has wide open spaces. The LGA1155 CPU is powered by a simple 4+2 phase VRM. It is wired to four DDR3 DIMM slots, supporting dual-channel DDR3 memory, and one PCI-Express 3.0 x16 slot. Three other PCI-Express 2.0 x1 slots, and a mini-PCIe slot make up its all-PCIe expansion area. SATA connectivity includes two SATA 6 Gb/s, three SATA 3 Gb/s, and one eSATA 3 Gb/s. The rear panel resembles that of the DH77EB, except the lack of the PS/2 combo port. There are quite a few legacy port headers.
Lastly, there's the DH77DF, which is bustling with activity on its limited PCB real-estate. The LGA1155 socket is powered by a 4+1 phase VRM. Intel made room for two full-size DDR3 DIMM slots. Expansion slots include a PCI-Express 3.0 x16, and a mini-PCIe. Five out of six SATA ports from the H77 PCH are utilized, with two SATA 6 Gb/s, two SATA 3 Gb/s, and one eSATA 3 Gb/s. DVI, HDMI, and DisplayPort make up its display connectivity. 8 channel HD audio, gigabit Ethernet, FireWire, and four USB 3.0 ports (two on the rear panel, two via headers), make for the rest of it.
