We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.
The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.
The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.
On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.
So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.
WARNING: Windows Mixed Reality PC desktop Graphics card upgrade can overload the Power supply
This is not relevant to laptops.
When thinking about upgrading for example a two year old NVidia graphics card this probably generated about 60 watts and needs a 250 watt power supply just for itself.
Therefore the PC case manufactures put a 500 Watt power supply in the case. The extreme gaming PC cases, Microsoft calls Windows Mixed Reality Ultra PC, have 850 to 1000 watt power supply.
Now if my graphics card is from NVidia GT750TB which requires loading 118 Watt then a 250 watt power unit is ok for driving the current machine and the original case has a 500 watt power supply.
Now lets look at that shiny new ASUS NVidia 1060 and calculate the new value which is now loading value of 340 watts requiring a 526 watt power supply.
When you install the ASUS NVidia 1060 will still work because many budget PSU don't have overload protection!, damaging motherboard, CPU and memory.
This means that you are left needing at least a 850 watt power supply. if you have one with overload protection that's £179!, the same price as the graphics card.
All the upgrades need to be installed preferably by a custom PC builder as there is mains power 240/110 volts involved, so add £40 to fit this.
Many people forget that ASUS NVidia 1060 require two slots, the ASUS NVidia 1080 requires three slots!!
All these costs add up in some PC cases doubling the unexpected costs.
Asus NVidia 1060 is £251 + 850 watt power supply £120 + installation, two days unable to use, £60. Total at least £431
on top of the £890 of the original machine
Finally now you have a CPU bottleneck and need another 8GB memory for rendering.
My local custom PC builder can build a WMR/VR for £1241 and cheaper if parts are recycled from the original PC.
For business this is simply buy a new WMR Ultra PC. For the hobbyist these are unexpected costs, but for either group any damage is unacceptable
