Some Computer Experts are morons.
All I wanted was a USB header Y-cable. Nobody makes one. Some Chinese company sells a dodgy little micro hub, which appears to take the two USB ports on your header and give you... two USB ports.
For god's sake, can't anyone read the pinout diagrams in their MoBo manuals? That header is two ports. The problem is every internal component that uses USB like my power supply or CPU cooler includes a keyed 9 pin connector with only four wires connected to the pins so that the turnips don't plug it in backwards and fry the device.
But Google Motherboard USB Port Splitter and you will find lots of sage advice from people who have no idea what they're talking about, all of them insisting you need all 9 pins to run USB. and recommending buying USB cards to get additional headers. Head, meet desk.
All you need is a short cable that on one side, takes the pins from port 1 and connects them to a header in the port 1 position, and on the other side takes the pins from port 2 and connects them to a header also in the port 1 position.
Nobody makes this as far as I can tell.
I may be forced to pry out the pins from one of my cables and insert them into the plug in the port 2 side of the other cable.

One search at Bing for "newegg motherboard dual usb header" and it was the 4th result on the 1st page. Plugging pins into a 2-row header sounds good too.

Yeah, that's a front panel adapter. Not the right solution.
Now, I've MADE header connectors before (lots of servo extensions for robots), but I couldn't keep the tools, alas. A good crimper is about $20, and an assortment of shells and pins can be found on Amazon (search Dupont connector) for various prices. I could thus make a y-cable adapter for about $30. (or less if I ordered just enough bits from Jameco). There seems to be enough demand, so I have no idea why the product doesn't exist.
But the cheap way is to move the pins to the other connector.

For example here is the wrong Chinese thing. It's actually a USB hub, takes the two ports on the MB header, (or just one of them) and turns them into 4. Also about half this price on Amazon.

"Front panel", seriously? It goes into both front and back, and the back includes ISA/PCI slot cover as well as rear panel cutouts, if your box has those. Look at the rear picture.

The NewEgg thing was a Front Panel connector, like the one built into my computer case. It connects to the header and gives you two USB type A connectors, which isn't suitable for my purpose. The Rear Panel connector you linked from Amazon likewise terminates in two USB type A connectors. I need those wires to terminate in headers instead.

I see now that your post included all the necessary information for someone with a modicum of reading comprehension. But my mind refused to believe that a power supply may have a USB interface. I'm afraid it's time for you to break out a soldering iron. Or, you could just use the blessed thing without USB. Hopefully that is still an option even these days.

It works without the USB, but I'm curious about the data. And I wonder if I was drawing too much power out of my old PSU. (I don't think it's worth the effort to try to get $40-$50 back in deprecated warranty value from it, so I may dissect it. The small piece of plastic that fell out of it may mean that I blew a FET.) I might be able to temporarily hook it up, just to get a read on it with the monitoring software, but the cooler takes priority. They both work without being hooked up.
BTW, the terminals are solderless. I'm debating buying a crimping tool (About $23, but useful forever) and a box of blocks and terminals to make the proper cable just so I can take a picture of it and say "You See Industry, THIS is what we need!" Of I could just save me money, move the terminals into another block and make a frankencable.
