In our recent run of overclocking focused motherboards, we have had a couple of interesting contenders. Sub $300 is a difficult market to attack for X99 overclockers, and MSI brings the X99S MPower which is the focus of today's review.

MSI X99S MPower Overview

While we have done a number of cheaper X99 overclocking motherboard reviews as of late, including the X99-SOC Champion and the X99 OC Formula, one common feature in these reviews has been how the manufacturers are learning how to get the balance right between making something desirable but also cost effective. We have remarked that while X99 is the high end expensive platform, users can still want to pair an i7-5820K with a cheap motherboard and get a six core overclocked beast. This is the aim of motherboards like these.

The MSI X99S MPower attacks this angle with a yellow and black color scheme (or as I read once, like a bee or police warning tape) at $300, making use of onboard OC buttons and an OC Genie button for overclocking. The rest of the motherboard comes with SATA Express, an M.2 PCIe 3.0 x4 port, extra USB 3.0 ports and an upgraded BIOS/software package from X79. The last MSI overclocking motherboard we tested, the Z97 MPower Max, was a nice product which we awarded and the X99S MPower wants to follow in that path.

Where MSI delivers is that the BIOS is easier to use than previous iterations, we get an XMP button in the BIOS to easily apply memory profiles and the overall aesthetic of the design which is something a user can build around to style their system. In our benchmark perspective, MSI performs similarly to other X99 products but does not enable multicore turbo, keeping it in the lower (but more common) performance bracket when at stock speeds.

However, there are a couple of downsides for comparison. Firstly, even at $300 it ends up approaching the mid-range pricing for X99. The Z97 model incorporated combined air/water cooling on the power delivery for less, for example. One of my big issues is that OC Genie, which we get a toggle switch for two modes this time around, is still that it does not push the CPU that much. MSI lacks a testing tool for overclocking and provides only a couple of presets, both of which give only a basic overclock. Another point of contention is that the bundled software offers a chance to overclock the CPU to 2.1 volts in plain daylight, which is asking for trouble.

The $300 price point is actually quite aggressive for X99, and along with the other motherboards we have reviewed the MSI still has a few (easily fixable) issues and doesn't push the boat in terms of technology but it ran through our suite without any issues.

Visual Inspection

Unlike the red of most motherboard gaming ranges, overclocking colors vary from company to company. In one corner we have red, another orange, a strong yellow and muted yellow, with MSI taking the last one on that list. It is clear they want to push a combination of black and yellow, because these two together signifies danger, or something similar. The amount of yellow on the MSI OC Certified range is along similar lines to that of MSI’s GPU Lightning range as well.

The X99S MPower uses a slightly modified CPU socket bracket which removes some of the elements to the rear side, allowing the socket area to be insulated better for sub-zero overclocking and attract less condensation with fewer metallic elements. The board has a full set of two-DIMMs per channel for memory, and although the slots are all black there is an easy-to-read guide on the board itself showing which DRAM slots to occupy first. Above the socket is our enhanced power delivery, and to keep costs down compared to the high end models the power delivery heatsink is not connected to the chipset heatsink. The socket area has easy access to four of the five onboard headers – two 4-pin CHA fans to the left of the DRAM, a 4-pin CPU at the top right, a 4-pin SYS at the top right also and a final 4-pin in the bottom right.

In the top right along with the fan headers is a two-digit debug display, useful for diagnosing boot-up issues. The power/reset buttons have been moved to the bottom of the board, which some manufacturers now prefer as the top of the board can get quite cold when sub-zero overclocking takes place over an 8-12 hour session. Below the debug display are the 24-pin ATX power connector and a USB 3.0 header sticking out of the board. This header is available for fast charging, hence the red color inside the header. We have another USB 3.0 header below this, at right angles to the motherboard and enabling cases that have four USB 3.0 ports on them. This is followed by our SATA ports, and at the bottom is a SATA Express port (with two of the SATA) sticking out of the board.

Along the bottom of the board are our power/reset buttons along with two DirectOC buttons. These adjust the BCLK frequency of the CPU in increments determined by the driver in Windows – either 1 MHz or 0.1 MHz. The OC Genie button follows, along with a switch which adjusts the OC Genie mode between two different OC levels. We test both in the overclocking section later in the review. Also on the bottom is a FastBoot button to get into the BIOS, the front panel header, two USB 2.0 headers, a BIOS select switch and a slow mode switch.

The PCIe lanes are somewhat oddly organized, requiring the first two GPUs to go into the first two full length GPU slots. So for a 40 PCIe-lane CPU, we get x16/x16/x8/x8 where the first slot reduces to x8 when the third is occupied.

To add to the confusion, the M.2 slot can either be in PCIe 3.0 x4 mode from the CPU, or PCIe 2.0 x2 mode from the PCH. However the manual has a handy table to tell you what goes where for what:

Essentially anything placed into the bottom full-length PCIe slot will reduce the M.2 slot down to PCIe 2.0 x2. Not shown in this table is a technical support for four-way GPU alignment, giving x16/x8/x8/x8, although single slot cards/PCIe ribbon cables would be required.

The left hand side of the board features MSI’s Audio Boost, which is an upgraded version of Realtek’s ALC1150 audio codec with an EMI shield, PCB separation and additional filter caps.

The rear panel of the board gives a combination PS/2 port (in black), two USB 2.0 ports, four USB 3.0 ports from the chipset, four USB 3.0 ports from a VIA VL805 controller, an Intel I210 network port and audio jacks.

    Thanks for the review but no info regarding the power delivery? It's the first thing I look into with an overclocking board. More for reliability than any extra clock speed. I'm aware phase count is not always a useful metric but it would be nice to include it.

    Anyway it's 12 phase a "ISL6388 6-phase PWM" with doublers. "Fairchild FDMF5823DC MOSEFTs" rated 55a. Twelve Solid Ferrite Chokes (SFC). Memory is "Two Powervation PV3203 controllers"

    Every manufacturer appears to be cheapening their boards that carry over from Z87 to Z97, but on X99, this is quite disappointing to hear. IR3550s are expensive, but an analog PWM on an overclocking board? This is a surprising choice, especially in the light of Asus' and GB's X99 boards. The X99 Deluxe pairs the nice "Blackwing" chokes with IR3550Ms, although it costs way more. Even the UD7, a non-OC geared board, comes in at just $20 more with the usual GB fare: all new IR, from the IR3580 PWM to the IR3556s.

    The ISL6388 is disappointing. This doesn't belong on MPower. So what if the FDMF5823 is one of Fairchild's DrMOS top-of-the-line products? The ISL6388 is on a completely different level. MSI has always flaunted their "Solid Ferrite Chokes" while hiding crappy MOSFETs/PWMs under heatsinks since Z77.

    In the end, the serious OC purchase will always be ASUS' Rampage Extreme series. I don't understand why you'd cheapen your overclock with a board that has cut high-end features to lower the cost on the most expensive consumer platform. Reply

    Actually analog PWM or digital PWM doesn't mean one is better than the either. An analog pwm can be just as good if not better than a digital pwm and these days digital and analog is so obscure.
    If you mean digital control loop vs analog loop its hard to tell which is totally better. As long as the control loop is making the right decisions in the right amount of time it doesn't matter if its digital or analog. Phase shedding or increasing can be done in analog or digital as long as its done. Digital control loops do offer non linear control so you can do things such as have smaller caps but analog interfaced with digital can do the same and at much less power usage. The one issue with digital control is the process time so your limited to how fast the clock can run. Thats why they use alot of phases, it makes it so that the slow digital loop can handle it by dividing the time by the number of phases so you might be using a board that has more phases not for you but to help the digital control loop out since digital loop requires processing time to do its computation and control. So as switching speeds increase digital control may have a harder time while analog pwm can go to 20mhz or more no problem.
    In the end its whichever solution gives the best performance and features people are willing to pay for

    I'm mildly surprised that MSI decided that this board could make due with only 2 12V connectors. The Z97 MPower used 3: 8pin, 4 pin, and 6pin PCIe; but its CPUs are lower power and is maxes out at 3GPUs vs potentially 4 here (with water cooling and if you can remove the video out ports on one card).

    What does 3DMark2001 XP Turbo in the BIOS do? Reply
  • Horza - Tuesday, February 17, 2015 - link

    Boosts 3DMark2001 scores I'd imagine. My Gigabyte board has a similar "Legacy Benchmark Enhancement" setting in the bios which apparently boosts 01 score and SuperPi. Reply

    I just don't get why anyone spends $250+ on a motherboard. I've always been able to overclock my cpus quite high (better than the average, let's say) using motherboards that are virtually free with a Microcenter CPU+MB bundle. The last few motherboards have been the MSI PC-Mate Z77, and I was able to overclock both a G3258 and a Devil's Canyon Core i5 to levels on par with the Anandtech review of those respective cpus. The cpu heatsink makes more of a difference than the motherboard. I haven't had any stability problems overclocking, going back over 10 years, with basic motherboards. Once you have a good overclock and stability, what more do you need? Reply

    You can't directly compare pricing of socket 2011 motherboards versus socket 1150 motherboards. They are entirely different beasts.

    As for the exact same platform, more money gives more features. Also, some people can afford to spend more, and enjoy owning a "premium" product.

    Why does someone pay for an iPhone when they can use a "almost the same" $100 Android phone? Why does someone pay for a top end Mercedes when a loaded Camry for $30,000 has power and leather everything, plus electronic gadgets?

    That said, I do agree with you to a point. Sometimes more cost means real benefits. However, sometimes that just means extra NICs and PCIe slots and fancy VRM heatsinks that you still won't use or benefit from.

    Choosing a motherboard is important, not just for overclocking capabilities. Whether you'd want SLI, extra USBs and SATA connectors, NIC, Wifi etc, Also some would like PCI/PS2 ports to carry on perips they want to incorporate into their new build. I learned this from many builds I'd built for myself. Essentially you are stuck with the motherboard you go with. I don't totally disagree with your point, but I've learned that cheap motherboards are just that...cheap.

    The most I will spend on a motherboard is $200 and I am quite satisfied with my ASRock Z97 Extreme 6. It took me months of research to settle on this. I'd happily pay an extra $50-100 for something I want.
