Only about two and a half years too late. Darn. Can't wait for the LGA1200 + GTX 1650 Super version to come out in 2022! Price: $500.
My sense is that it was created for a specialized product (e.g. console, all-in-one PC, etc.), and now they're selling off some overstock/replacement parts. The non-stardard form factord and weird connector configuration is just screaming this. It's even possible they used it for some kind of video surveillance (facial recognition) appliance, since a GTX 1050 Ti packs nearly 2 TFLOPS of compute power.
If the part is being sold in very low volume and as a repair part, then the inflated price is justified. If it's just overstock, then maybe they're starting high and trying to find what price the market would support.
In either case, it'd be interesting to know how much lag exists between the US and Chinese markets. My sense is that they get new products about the same time as we do, but maybe it takes 6 months or more for cost-reduced models to start ramping the volumes in their market. For sure, a GTX 1050 Ti is not as obsolete there, as it is here.
