Power supply question

The following is taken from the installation instructions that came with an
Intel D865GBF mainboard:

"Connect the 12 V processor core voltage power supply cable to the 2x2
connector and connect the main power cable to the 2x10 connector."

"CAUTION: Failure to use an ATX 12V power supply, or not connecting the 12 V
processor core voltage power supply connector to Desktop Board D865GBF/GLC may
result in damage to the desktop board and/or power supply."

Will the power supply *really* be damaged by not connecting the 2x2 connector?
I'm still using my older motherboard for a while which doesn't have the newer
2x2 connector.
And, it's difficult to find a newer power supply without it.

Thanks for any advice.

No. The instructions refer only to the new mobo.
Just tie back the 12V cable in a safe place.

What Pen said. Just don't run the new mobo without it.

It shouldn't harm the PSU.
 
No. I'ts optional to use it.

There was a time when CPUs used less current and a system might be OK
without using the connector but it could damage the power supply if you
consider the wire and connector part of it, if they overheat.

Yes, look at my now old computers power connectors.
The +5V was a little hot!

I had to solder the PSU wires direct to the motherboard before it
melt down. It's an old Pentium Pro 200 MHz with big current draw
and a lot of other things draw a lot of current from +5V.
Almost everything takes the current from +5V in this old
AT style computer.
