MSI Z97 Gaming 5
MSI certainly grabs attention with its matte black PCB and red accents. But the hardware focuses primarily on the Z97 platform’s integrated features. Four I/O panel USB 2.0 ports bolster connectivity on a board that offers a total of six USB 3.0 ports (four of which are also found around back).
The single GbE connection gets a slight boost from its PCIe-based Killer controller, but other PCIe connections are dedicated to slots and the M.2 interface. The chipset has only eight PCIe lanes, so the Z97 Gaming 5 presents four x1 slots in addition to the network controller and two-lane M.2 interface. The M.2 port also steals two SATA ports when a card is installed there.
Notice that the Z97 Gaming 5 has no SATA Express cable provision? That’s because MSI agrees with my boss that the M.2 interface is mostly useful in notebooks that lack space for RAID arrays, and that RAID arrays are most practical in desktops. That certainly gets around the chipset lane limitations experienced in several competing products, but it makes me question where the single-remaining lane might have otherwise been used. MSI could have just as easily omitted the x1 slot beneath the top graphics slot to get the second lane needed for that interface.
And yet it still sounds like MSI is getting around the PCIe limits of some competitors in its x16 slots. That's because the bottom slot steals four lanes from the middle slot. Nvidia insists its cards need at least x8 for SLI, so using the bottom slot could prevent the top and middle slots from supporting SLI. MSI could have instead made the bottom slot x1/x4 switchable to support slower cards without that issue, but its documentation says it didn’t. Those limitations effectively make it a non-SLI graphics slot, whether those cards are used for CrossFire, an OpenCL-oriented accelerator, or just a massive wall of displays.
The Z97 Gaming 5 features a row of voltage detection points along the front edge and a two-digit POST code display at the bottom edge, both to make overclockers happy. The firm also adds a three-pin audio power input header for output current enhancement, along with a switch to select internal or external power sources (but that sounds just a little gimmicky to us).
The Z97X Gaming 5 includes a flexible SLI bridge and a four-to-three-pin audio power input adapter. But it also only includes two SATA cables. I typically use three cables in a basic build.
