How many standoffs

For an ATX board, how many standoffs should you use. I installed 5 and then while building I say I had another 4 in the bag. Should I go through the effort of taking my board out and installing some more standoffs?

  1. Just because it's me, I would, but you should be fine with just five installed (assuming you're using the four corner and one center standoff).

  2. want to use all nine. there should be three on each edge of the mb and two or three in the center. the standoffs are there to keep the mb from shorting to the mb tray but also use for grounding points.
  3. Yeah, friend told me to use all nine too. My manual only listed 5 standoffs, and then I saw the other four once I was already building and had only used 5 (4 were pre installed)
  4. Why does it need so much force to line up the standoffs. The springy bits on the I/O shield are blocking it D:
    There's only holes for 6 standoffs on my mobo
  5. Use all nine if possible. Obviously since your motherboard has only 6 standoffs, that is all you can use. Do not over tighten the standoffs or the motherboard mounting screws.
  6. My motherboard has openings for 7 or 8, but only 6 line up with the case so I installed six. Feels like far too much effort to get them all lined up right, was sure something want right

    Just make sure that you have used the right stand-offs on the case. Cases generally have more standooff holes to suit different types of motherboards (ATX, mATX, etc.). There should be a mounting template that came with your motherboard and this template is to be used to install the standoffs on the case holes.

    If the template is missing, then place the motherboard in the case and mark the mounting holes with a marker. This will help with the correct location for the standoffs.
  8. The Standard ATX Motherboard form factor is 12 in × 9.6 in (30.5 cm × 24.4 cm).

    Your GIGABYTE GA-H87-HD3 motherboard is 12 in x 8.86 in (30.5cm x 22.5cm) which is shorter in depth than the standard ATX.

    You will only be able to install a total of six motherboard mounting screws with the Zalman Z11 Plus. The seventh mounting hole on the motherboard will not have a corresponding mounting post because there is no screw hole in the proper location on the motherboard tray to mount it.
