Well, if you always tell the full truth, I genuinely would be surprised. But hey this is the internet, so what do I know.

As for ordering PSUs, well, I guess if you are ordering a dozen or so, yes, may you can. However if you need to order hundreds you don't go to amazon or newegg or your favorite online retailer. You go to a reliable and reputable manufacturer and order them. This being the USA that typically means China or Taiwan. Since Giga-Watt is just another customer to those guys, and probably not a particularly big customer, they had to wait for their order to be processed. Once they purchased the PSUs they had to get them shipped to the USA, that's usually in a container since air freight is prohibitively expensive for big and heavy items. And then let's not forget customs. That depends a lot on what is being shipped and how the customs agents feel that day.

So in the grand scheme of things, I think Giga-Watt did OK getting the replacement UL certified power supplies as quickly as they did. Also remember that the PSUs are different depending on what miner was purchased. I would also imagine that Giga-Watt also purchased some additional PSUs to have on hand for repairs should any in use decide that they want to let out all their magic smoke and stop making the right voltages.
