8-pin EPS question

post #1 of 11
Thread Starter 
I have my 8 pin EPS power plugged into my motherboard and with one of my rads installed, It's impossible to get out.
When I leak test my loop, can I just leave it plugged in while taking out the 24-pin? Will it still power the CPU and ruin it if there is a leak?

Thanks!

That does supply power to the CPU. The only answer I have that is 100% safe would be to hook up another power supply to the watercooling loop.

Thanks!

Another option would be to get an 8 Pin EPS extension cable like this. Then Just unplug the PS from the extension for testing purposes.

When I was leak testing I left the 8 pin EPS in and just shorted the 24 pin power cable if that helps

No.

If the ATX24 is not plugged in, and more specifically if the green PS_ON wire is not connected to the motherboard, then the motherboard will not switch on and not draw any power from the EPS connector.

However, if somehow you pour water into the EPS connector then it will short. That might damage the PSU, but the CPU will be unaffected.

Disagree. I believe the whole point is that the PSU is jumpered and is powering the pump in the loop for testing. This means the circuits connected to the EPS connector will be receiving juice. Come to think of it, having this connection live may be a bad idea without involving the threat from a leak. Power being fed into something that "isn't on" is never a great idea.

The PSU will not even turn on for more than a split second (or not at all) if it is plugged in while the 24 pin is jumpered. Ask me how I know cigar.gif

I do want to know how you know. Your comment is completely opposite my own, personal, done it many times experience.

So you've had your 8-pin EPS plugged in while jumpering the 24-pin many times? I've only done it twice by accident and it did nothing on one, and immediately shut off on the other. Maybe it depends on the PSU configuration, regardless its best for him to just unplug it to be safe.
