Since I posted this just over 2 days ago, the seller has sold an extra 52 power supplies. So the seller does have to potential to sell a huge quantity of items before non delivery would become an issue.
The tracking numbers could easily be genuine if the seller sends something like an empty packet deliberately to non-existent address in the same suburb. There would be all this tracking information and nothing ever arrives.
What puzzles me is how a new seller can be selling so many items. Usually they limit new sellers to a low number of items - such as 10, and I gather is you have a good record for 3 months, you can request an increase. This seller started March 2, sold a few items to get a record, and now suddenly has about 400 items for sale - mostly $9.99 or less. This includes things like $177 Mitutoyo callipers for under $11.
I cannot understand how this seller can be allowed to sell so much after just 2 months, but I think eBay will be having a lot of fun soon. Looking at the sales, and probably something like 1000 items have been sold already in probably a week or something like that. If the rate accelerates, it could be a massive number of sales before the deliveries are due. Over $50k or $100K of sales wouldn't be surprising.
But of those $9.99 Fluke multimeters and Fluke digital IR thermometers look nice. Maybe I should ....
Edit: Just noticed the seller excludes China, Hong Kong, Macau and Taiwan. In other words sells anywhere but locally where delivery would have to be just a few days.
