My PSU(for my computer) has a switch at the back for turning it on and
off. Is it easy to disable the switch and make it like a typical PSU
without the switch?

Is there a name for the PSUs with switches at the back. A name that
distinguishes them from the PSUs withotu switches at the back

My KVM switch isn't compatible with PSUs with switches at the back.
When I power off the computer, the kvm thinks the comp is still on, but
then doesn't let me move to another comp. I have to turn the comp off
at the back in order for the kvm to realise that the comp is off.

No. You have an ATX power supply attached to an ATX motherboard.

To be able to have Windows "Shut Down" the system, and for the system
to be able to "wake up" at a certain time, or because the modem detects
the phone ringing, or various other reasons, some of the components need
to have power all the time. When you "Shut Down", your motherboard
sends a signal to the PSU telling it to turn off, and your front-mounted
"power switch" is actually just a signalling device that tells the motherboard
to tell the PSU to turn on/off.

Yours is "ATX".
The ones with no switch at the back are the older "AT". They have a
switch at the front instead, that actually cuts off the power. There's no
way for Windows to have an AT system automatically shut down.

You're on your own for that part, or until someone else replies.

Replace the kvm. A psu without a switch will behave the same way,
except you'll have to pull the plug.

you seriosuly tellin em i have an AT PSU?!

But the MOBO connector is 1 connector. Those old AT PSUs had it split
in 2 connectors.
And there is no extra plug for a monitor to plug in.

I'm sure there is a power_good or whatever the line is on the PSU.
Besides. It does shut down the whole computer when I shut down windows
.. All the fans go off.

Switch on the front?
I know what you mean.
AT PSUs have a great thick long cable with a switch on the end. The
cable runs all the way to the front of the computer and the computer
case has a plastic button when when pushed - literally - pushes that
PSU's switch .

I don't have that. I have an ATX PSU with a switch - (like a light
switch not a phallic knob) on the end.

Mine is like this

PSUs without the switch behave ok.

All PSUs i'm referring to are ATX.

The theroy is. The PSUs with a switch give power to the keyb/mouse
connectors even when the computer is off (fans off, lgihts off, sounds
off, everything off, power_good signal LOW. Off Off Off).

You have a slightly unusual ATX supply.
Most ATX supplies do not have the rear panel switch;
otherwise it is normal ATX. There is no need to remove it
as it would not solve your problem, since that
switch is hard wired into the power line. Just
leaving it on is the equivalent of removing it.
Your KVM is apparently detecting the standby
5VSB from the machine you are turning off, and the standby
volts does turn off when you throw the back panel switch.
Try turning off in the BIOS any choices about Wake on LAN
or similar and see if that solves your problem.

You'll want to replace that POS KVM switch. It's a waste of the materials
that it's made of.

both wake on keybaord and a wake on LAN were disabled. I'll just get
PSUs without the switch - i don't know what they're called but i'll
look at pics and make enquiries.

I love the kvm switch. I've had problems with previous ones. I
recommend this kvm switch to everybody. It's a Zonet KVM 3004 (4 port
kvm switch). It was on newegg with almost 40 positive reviews
averaging at full marks.

My only gripe with it is that it's not a tidy design.

I could buy another 5 KVMs and they might all have the same problem.

Easiest and safest to buy some new PSUs. there's a slight risk that i
don't know what 'switchless' PSUs are called, but pics do the job.

That's a waste of money. Your problem is the KVM
not the power supply. If you leave the switch on
all the time, the two are identical. You've been told
this at twice before.
