It looks like you pushed it in from the center. It’s supposed to be a tight fit and literally “pop” into place, but you’re supposed to push along the edges. No real way to fix this unless you take off your mobo and io shield and bend it back to shape. Answer from Miserable_Speed5474 on reddit.com

r/buildapc on Reddit: IO shield not lining up
July 7, 2020 -

Good morning.

I have a picture linked of my recent build of a MSI B450 Tomahawk Max installed into a Cooler Master Masterbox K501L. As you can see the BIOS Flash BIOS Button and USB ports seem out of alignment and slightly raised. I have checked and the motherboard is secured firmly to the stand offs. All the stand offs were pre installed in the case. The IO shield is secured in place correctly.

What could be the issue here? Any idea. I would rather not take apart the PC and fix, yet if I have to I will.

Thanks for any advice.

computer building - IO shield is causing my motherboard to not align with case standoffs - Super User
December 1, 2020 - One thing I did note was that the IO-shield seems to be a little too thin, i.e. it could be moved a little bit left and right in the slot (which I assume comes from it not being snapped into place?) It shouldn't be necessary but what you describe seems to be common with this particular case. Since the I/O shield is typically just snapped into place, the fact the I/O shield is screwed in, it looks like it was intentionally designed to be removed.

I spend the last week trying to insert my GTX 1080 into my case no matter how hard i pushed or wiggled the gpu would always be partially outside the slot. Now i noticed that the standoffs and the io shield don't align. I was wondering if this was really the case and if it's the case what should i do? replace the standoffs with ones that align with the IO shield?

(ones installed are the ones that came with the pc when i bought it used and the IO shield is inserted correctly)

February 19, 2023 - I don't really have any links or anything but when I did the standoff mod I had to kind of mix and match 2 different stand offs for each post because one full length one made my io not really line up with the case. I'd suggest buying a pack with different sizes so you have some flexibility, just in case you run into the same.

UPDATE #2:

Talked to ASUS component support and they want me to attempt to return the board to the retailer, even if it is a manufacturing defect. At this point I'll probably just jump to a different motherboard from a different manufacturer. Thanks everyone for your help.

Can anybody recommend a different motherboard? Here is my part list.

Troubleshooting Help:

What is your parts list? Consider formatting your parts list.

  • ThermalTake Core V71 chassis

  • ASUS Z97-a-USB3.1 motherboard

Part List

Describe your problem. List any error messages and symptoms. Be descriptive.

Installed a new MB on a new build. MB is an ASUS Z97-a-USB3.1. The I/O shield does not line up with the motherboard. I'm using a Full ATX ThermalTake chassis (Core_V71). Other ATX boards and shields line up just fine. The z97-a/usb3.1 is attached to the correct standoffs, and the stand offs are in the chassis correctly.

List anything you've done in attempt to diagnose or fix the problem.

I'm unable to install the shield and motherboard unless one of the DVI nuts is removed. Once installed, I'm unable to connect HDMI or Display Port cables.

I contacted ASUS support and they recommend I make sure the chassis and MB are compatible, and if they are, I should contact their store to purchase a new shield.

Post relevant photos of build/parts here.

Will update with a picture at first chance. Imagine the top edge of the display port and hdmi ports being slitly covered, enough to make them unusable.

UPDATE: here is a picture

The side of the videos ports (that now sit vertical when upright) are blocked.

Provide any additional details you wish below.

The last motherboard to fit into this case was an earlier model Z97-A. Currently researching if it is within retailers (Fry's) return policy, but believe it is too late for that option.

January 9, 2023 -

It's my first time build a pc, I got the MSI B660 Tomahawk motherboard with the Lian Li Lancool 215 case. Got to the point where I need to put the motherboard in the case. The io shield doesn't quite line up right on the case, (hard to see) it is crooked and it doesn't go all the way against the case to be flush. It is not getting stuck on the fan but this means the screws do not line up. The io shield is connected to the motherboard.

Please help I spent 7 hours researching this and found nobody else with the same issue. They were all related to standoff screws being put in wrong.

I recently put together a new desktop. My case is corsair 100r, and my motherboard is asus prime z490-p. I've booted up and everything is stable and without problem. However at the back the motherboard doesn't line up with the IO shield properly. Only ports on one side smoothly go in. images

I've tried adjusting standoffs, tightening one and loosening the other (slightly) to no avail. I suspect maybe the ground prongs are stuck in the HDMI port as shown in the images?

r/buildapc on Reddit: Motherboard IO Shield alignment problem. Need help!
February 18, 2020 -

Hello everybody - I'm currently building my PC but I've stumbled upon an issue with my motherboard and its IO shield alignment. While I understand that there have been many threads regarding the alignment of the motherboard and its IO shield but the threads that I have seen seem to have a different problem to mine.

While others may have their motherboard too low for the IO shield (which is usually fixed by adding the appropriate standoffs to increase the height of the motherboard; mine seems to be the opposite - where my motherboard seems to high for the IO shield. While most of the ports can be used, a few (especially the bios button and the usb slots directly beneath) can't. I have mounted the motherboard correctly, with all the standoffs in the correct location and the screws in. The motherboard seems to be attached appropriately.

I've already tried moving the standoffs around, raising the height of the standoffs (by loosening them - not a good idea). The image is what it looks like when the standoffs are tightened. The alignment of the holes for the motherboard and the standoffs are also fine - but the problem remains.

The IO shield itself seems to be fitted in correctly, I snapped all four corners in, and it fits properly. The motherboard is pushed down as far as I dare go. I've not tried the method of mounting it without the standoffs as I'm afraid of damaging my motherboard.

For context purposes, I'm trying to fit an MSI B450M Mortar Max into a Cooler Master NR600 case. I've spent many hours on this today alone and I'm getting flustered. Halp..

So after removing everything I've managed to get some pictures for further reference.

Standoff location: https://imgur.com/vfJgsMA (the white denotes the standoffs that I removed as it doesn't seem to do anything (there is no space on the motherboard to use that standoff, as can be seen in the next image)

Motherboard screw locations: https://imgur.com/5pbTdXo

But as of now (thanks to the suggestions by the community) I suspect that my solution is to somehow find shorter standoffs. I know they can be found on amazon and ebay - but the shipping time is not very nice. I suspect that this standoff is the one that is causing problems.

Or it could also be the other standoffs on the top row

https://imgur.com/G5jGGTz

What do you guys think? Should I change just one standoff or the others too (the top row of standoffs)

// EDIT // 18-2-2020 //

After speaking to Cooler Master's support (and have them go through this reddit page) my problem is finally solved! The solution to this is to NOT install the two tall standoffs. Whilst initially I assumed they were slightly taller to act as a pilot guide for the motherboards placement, it looks like they were the ones causing the issue. So thank you to all that helped! You guys rock!
