Computer Completely Bricks When Wi-Fi Card is Installed

[Zyr]

So I have a very weird problem. I built up my first new computer yesterday, and everything worked fine. I decided to insert my Wi-Fi card ( with the power turned off, though ) and realised I ordered it for the wrong slot.

So I looked up if it's okay to put a PCIE x1 cards into a PCIE1 x16 slot and apparently it is. But my computer completely bricks when I put it in, with no power reaching anywhere.

My mobo has LEDs that come on when plugged in, and those weren't even coming on. It works when I unplug the card.

Tldr: my Wi-Fi card causes my computer to have no power, help.

Just to clarify, my psu is 620W, and none of my components should be draining all the power.

Do you have a LAN connector on your motherboard meaning it uses a cable to provide internet for the PC?

I don't think 'brick' is the correct description for your situation and just adds to the confusion. Can't you at least enter BIOS?

insert in lowest pci-e slot?

also it will help if you provide complete brand/model for your pci-e wifi adapter and mobo.

Your PSU is rated for 620W but that doesn't mean it can actually deliver that. What make and model is it? Sounds like it may be defective.

We need full system specs

Agreed. Sounds like something isn't compatible, or like something may've actually failed or been DOA.

To avoid confusion, when I say the computer bricks, I mean it does not even switch on. There is no power getting anywhere.

The only other slots I have are PCI slots and PCIE slots that are slightly smaller than what the card will fit in to.

Here are full specs.
I7 7700k @ 4.2ghz
Evga Superclocked GTX 1050TI
Seasonic S12-II 620W 80+ Bronze PSU
Zalman Z11 case
1x 8Gb DDR4 RAM
Coolmaster Hyper 103 CPU Aircooler
Windows 10 Pro Trial Version
Asus Prime B250-Pro Motherboard

The motherboard does have onboard LAN, except I don't have an Ethernet cable that can reach the room my computer is in.

The Wi-Fi card is the Intel 3160.HMWWB.R Dual Band Wireless-AC PCI Express Half Mini Card Network Adapter.

dose it work if you take the wifi card back out?

Because if not, this is sounding like a total PSU failure.

It could also be a motherboard problem, everything he has goes directly through it

True. Whatever the cause, it sounds like a mechanical problem that isn't related to the WiFi card. More likely the PSU or Motherboard had a mechanical fault and failed almost instantly. The timing also fits - OP would've been right at the bottom of the Bathtub Curve when it failed.

The Bathtub Curve refers to how defective parts almost always fail within the first 30 minutes. On a graph the failure rate against passing time looks like a rolltop bathtub. It dips steeply down, flatlines at rock bottom, then improves on an upward angle.

The computer works perfectly fine once the card is out. But when I put the card in, nothing happens. Not so much as a motherboard light comes on. Remove the card and it powers on like nothing happened.

That's bizarre. I've never heard of anything like that.

Try another slot, but if the problem persists I'd start thinking about a PSU swap.

I am currently at college at the moment so as soon as I get back I will swap the card into another slot.
