MSI Z87 M Power vs MSI Z87 M Power Max?

post #1 of 9
Thread Starter 
I'm really drawn to these boards due to the 8x/8x PCIe where a lot of boards are only doing 8/4/4/4. Was originally looking a the Gigabytes OC but this was a turn off. Anyways between the two MSI boards is it worth it to spend the extra 30 bucks on the Max? Looks like its just more VRM witch may not be worth while since Haswell seems to be heat and not power limited.


What is your guys take?

Hope someone that knows more then me can chime in, wanna walk into a microcenter as soon as it opens tomorrow and pick one up

Also considering the MPower. Microcenter has it? It's not listed on there website.

What do you mean other boards do 8/4/4/4? If you only use 2 slots they will still do 8/8 as these MSI boards.

As for regular vs MAX. Well the only major difference is 16 phases vs 20 phases.

Now I hope that to get 16 phases they used doubling instead of quadrupling which they must use for 20 phases. After all they use 8 phase capable digital PWM (at least for GD65). In that case 8 phases sound better than 5 phases.

Also there is no info available on what MOSFETs they use, but on XPower they has IR3550. So they either use those, IR3553, or PowerPAKs identical to Z87 GD65 and Z77X-UD3H.

As said, atm it's just guessing, but in either case the regular MPower should be more than enough for any regular OC.

Is that 8x/8x on every board true? Seems like MSI is the only one that lists that..

Every board that supports SLI does X8/X8 at least once. 4-way SLI boards must do X8/X8/X8/X8.

There are 8 blocks X2 each in SB/IB and Haswell CPUs. Then there are PCI-E switches on the motherboards that distribute the lanes on the board. First slot runs at X16 until you drop a GPU in the second. When a device is detected in the second slot, the PCI-E switch moves X8 from the first slot to second; thus, you get X8/X8, and so on.

I'm sure that at least Gigabyte has this covered in their block diagram in their manuals.

Normally it's PCIE 3.0 x16 for single, x8 /x8 for SLI or Xfire , x8/x4/x4 for tri sli or tri-fire , Haswell Z87 has an extra PCIe 2.0 x8

You need PLX chip for x16/x16 iirc
