Power Consumption

Power consumption was tested on the system as a whole with a wall meter connected to the OCZ 1250W power supply, while in a single MSI GTX 770 Lightning GPU configuration. This power supply is Gold rated, and as I am in the UK on a 230-240 V supply, leads to ~75% efficiency > 50W, and 90%+ efficiency at 250W, which is suitable for both idle and multi-GPU loading. This method of power reading allows us to compare the power management of the UEFI and the board to supply components with power under load, and includes typical PSU losses due to efficiency. These are the real world values that consumers may expect from a typical system (minus the monitor) using this motherboard.

While this method for power measurement may not be ideal, and you feel these numbers are not representative due to the high wattage power supply being used (we use the same PSU to remain consistent over a series of reviews, and the fact that some boards on our test bed get tested with three or four high powered GPUs), the important point to take away is the relationship between the numbers. These boards are all under the same conditions, and thus the differences between them should be easy to spot.

Power Consumption - Long IdlePower Consumption - IdlePower Consumption - OCCT

Despite being a small motherboard with few extra components and Military Class 4 styling, the MSI A88XM-E35 uses more power than the IR355x ICs on the GIGABYTE motherboard, known for their high efficiency.

Windows 7 POST Time

Different motherboards have different POST sequences before an operating system is initialized. A lot of this is dependent on the board itself, and POST boot time is determined by the controllers on board (and the sequence of how those extras are organized). As part of our testing, we are now going to look at the POST Boot Time - this is the time from pressing the ON button on the computer to when Windows 7 starts loading. (We discount Windows loading as it is highly variable given Windows specific features.)  These results are subject to human error, so please allow +/- 1 second in these results.

POST (Power-On Self-Test) Time - Single MSI GTX 770

Motherboard manufacturers ultimately spend more time optimizing their more expensive products. With the A88XM-E35 sitting so low on the product stack, POST optimization is an afterthought.

    Also, PS/2 is interrupt-driven, USB requires the CPU to poll the ports. The effect of polling is to use/waste CPU cycles checking if the mouse has moved or a key has been pressed.

    Interrupt-driven I/O is superior, as it does not waste CPU cycles. The CPU only services the interrupt handler (keyboard/mouse code) when you press a key or move the mouse.

    It may be 2014, but PS/2 is a better way to connect both mouse and keyboard than USB. I wish all vendors put both PS/2 ports on all motherboards.

    I seriously doubt any computer from this decade or even the past decade is noticeably slowed down by polling the USB ports.

    I agree. He should just state that he wants the connections, because otherwise, they should be dead.
  • Powerlurker - Friday, April 4, 2014 - link

    My assumption is that PS2 ports are still used in industrial computing. They are also a little bit cheaper. Last I checked, HP would cut about $5 or so off the price if you went with a PS2 keyboard over USB. If you're a corporate purchasing agent buying 1000 systems, that's an nontrivial amount of cash with practically no downside.
  • dananski - Friday, April 4, 2014 - link

    N-key rollover is why I'd want ps2, but more likely it's that if they're buying a budget board, they might be reusing a really old keyboard.
  • sfuzzz - Tuesday, April 8, 2014 - link

    It was an half-joke. No, I think the real reasons are that the PS/2 controller is integrated and fully functional on all chipsets and PS/2 keyboards are guaranteed to always work, especially on BIOS. Call it a failsafe solution

    Thank you for reviewing a motherboard with a price that's not 3-digits, Ian!
  • LucinaHSacco - Thursday, April 3, 2014 - link

    So how about an AMD Kaveri-supporting A88X motherboard priced at just £40? That would surely get some attention, right? The MSI A88XM-E35 is that board and we have it under the spotlight today. http://is.gd/mGuvSU

    Ian, it is "bear that in mind" eg to keep in mind, not "bare that in mind" (naked in mind?! Hate to nitpick but this is at least the second article on this site I've seen it in.

    Also as other commenters have mentioned what is going on with the overheating of the VRMs? Specific chips or revisions only if all new chips are causing this?
  • zodiacsoulmate - Thursday, April 3, 2014 - link

    The first thing I noticed when taking the motherboard out of the anti-static bag was the lack of a power delivery heatsink.
    What heatsink is that???????????
    Isn't it the little blue thing on the mobo?
