When filling a loop, disconnect all power cables?

[CorCat87]

When filling my loop, with the 24 pin jumper. Is it necessary to disconnect all the other cables. CPU, GPU, SSDs ect. Or can I leave them in. On my first fill I disconnected them. But I was wondering for future fills and flushes can I just leave those in.

No real reason to disconnect other than it may get wet and you will have to thoroughly dry them before plugging

That is the point of removing the 24p to use the jumper. Remove all the cables. 
 

if you leave them all in, might as well just turn the pc on like normal. Which is what I do every time.

I'd definitely disconnect them just to be sure.

Ideally you just want the pump powered and that is it.

That way if there are any leaks, you're not frying powered on components.

I typically use another PSU for this, or unplug the power to everything else from the PSU side if I don't have another.

has it ever leaked while filling?

I've burnt out LEDs because things were plugged in. Would definitely recommend unplugging everything.

About half of the time yea. Plenty of leaks. Pump hose blew off and emptied itself on my psu. Other times I covered several cards as the bridge wasn’t seated. Even had fluid under the cpu between the pins.

and you still think it is a good idea?

Yep. Not wasting time unplugging stuff. Not when I can just fill the loop and then the pump to max in windows. Same way I do all my rigs. Nothing has happened, as nothing can happen.

I had a feeling it would be mixed, haha. My worry is that sending power off and on in quick succession to devices might fry them. I can somewhat easily get to all connection so I think I'll just remove them to be safe. Thanks for your all your input

[Mick Naughty]

If that were to happen it means the psu is messed up. Like I said, not unplugging it all is the same as leaving the 24pin in when you power it up. 
Prolly have to disconnect the pump sensor but not sure which one you have. That way the pump can go to max.

Just to illustrate my point further, here is my system where I had left most things plugged in while flicking thing on and off during filling. The PSU is RM750x a fairly good quality PSU.

 

The LED strip on the monoblock completely died. The LED in the SLI bridge was not capable of showing red (assuming the red LEDs burnt) and so was stuck on green and blue. The blue LEDs of the left strip on the bottom ones were also dead and so were stuck on yellow.

 

Its a situation where "you might get away with it" but to say it always is fine and is unneccesary would be poor advise. It's somewhat like saying "I've never been run over crossing a red light, there is no need to wait at a crossing". Maybe true if you are particularly vigilent, but it still wouldn't be good advise.
