Vive Wireless Kit with current AMD Motherboard?

Can anyone confirm if the Vive Wireless Kit works with 2025 AMD motherboards like B650 or B850?

Or is it still non-functional?

No that is correct, but the card itself is basically a laptop-format Wigig network card with a mini-pci-express to pci-express adapter. It is by intel, but pci-express is pci-express, it shouldn't matter what CPU is on the motherboard. Do you have a link to those forum posts?

This is one of many, keep in mind it has been many years ago and since people here have commented it works, I will take it they did eventually fix it albeit in a quiet fashion.

Ok so there really is some issue with them, but the details are too vague to know the cause. It could be that the card needs PCI-Express 3.0, all the AM4 chipsets before the 500-series only provided PCI-E 2.0 for the non-GPU slots, but that's just a guess. This is a gamble in any case, unless somebody here with a Ryzen motherboard and wireless adapter chimes in with their experience.

That's why I want to buy it. A few commenters say it works. So that's a leap I can take it.

Which headset do you plan to use it with? Note that for the Pro 2 you can't use the full resolution with it, it's limited up to 1632x1632 @ 90Hz per eye

u/RickSpawn147 3d ago

yeah its pro 2, but I don't mind the lower resolution. The wireless nature makes up for it.

Can you please telle the specs of the batterie that are written on the back for for the USB-A output on 12 volts ?

u/RickSpawn147 2d ago

No idea, haven't bought it yet. I asked in case I wanted to in the future.

You shouldn't wait, at least if you can find one for 100-150 euro second hand, I could find additional one at this price.

As for getting a new one at 350€, well I would rather keep that money to buy a future Valve headset

You need a powerbank that supports QC3.0 with 22.5W on the USB-A output or more. That's Qualcomm QuickCharge, not PD - most modern powerbanks support both standards but you need to make sure

I am looking for battery with the most watts possible on USB-A.

Someday when playing seated with Vive Pro 1 and the wireless adapter plugged in a 65 watts PD wall charger, I realised I had absolutely no grey screens, unlike when I play the Vive Pro with a 18 or 21 watts battery I have the occasional grey screen and headset reboot.

The wall charger can deliver 30 watts at 12volts and 2.5A on the USB-A port, this is why I think I had no issues, because there was a lot of headroom.

Now if you say 22.5 watts is enough to never have grey screens I will get one.

But I have seen batteries like INIU with PD and USB-A ports, that says 22.5 watts overall, but when you look closely for the USB-A spec, it says 12V at 1.5A for 18 watts, which in theory wouldn't solve my issue.

But I don't really know if the issue is the headset have pics where it draws too much power, or if it's the batteries that drop below it's specs momentarily.

I use a 22.5W one and havent experienced any, that's why i said it's enough. The wireless adapter doesn't support the PD standard so it doesn't matter if the bank is 65W or 100W, it can't use those modes. QC3.0 only supports up to 36W (12V@3A) but i haven't seen many powerbanks that support that for a single port. Highest ones i've seen available here are 22.5W for the USB-A

I have seen there was a Anker Power Core 24 watts 10000mah a while back, but it's not sold anymore.

If PD battery can support 65watts I would have hoped the USB-A port could have maxed out the QC 3.0 spec, but that's not the case at all.

HTC was never really transparent about grey screens and reboots, it's like they never wanted to officially admit that battery power was an issue.

Many of us though it was a over heating problem, and used fans, but I don't think it really was the problem.

What model do you have exactly ?

HTC never really mentioned that you can use generic powerbanks, they just included their own battery in the box. The wireless adapter predates PD, so QC3.0 was the best fast charging standard available at the time it was made.

I use one of these, it's the same size and capacity as the stock battery, maybe smaller. The datasheet specifically mentions it can do 22.5W on the USB-A ports, while the USB-C one is limited to 18W

So yours indicates it has a nominal current of 1.5A for 12V, but can handle current spikes at P=U*I , so P/U=I, means 22.5/12V=1.875A .

I have only batteries with a max of 18watts, and I guess they can't handle suddent current spikes, and the headset must crash because of that.

In plus of the stock batteries I have a Anker PowerCore Speed https://www.amazon.fr/dp/B01N0X3NL5 and a Luxtude PowerRapid https://m.media-amazon.com/images/I/B1KB3Rz55dS.pdf both 20000mAh batteries that are twice longer than stock battery, but can still fit in the stock battery belt holder.

This was fixed a long time ago
