Filling The Water Loop

[ASAP_Gooby]

When I'm filling the loop with water, should I disconnect all the other plugs from the power supply?

Are you worried about leaks?

[Lurick]

You should, yes. The main reason for this is after you fill you'll need to jumper the two pins on the 24-pin to start the pump to get the liquid flowing through the system and start the bleeding process. Since this takes several times it can cause damage to your components to switch everything on and off several times in a short period.

Alternatively - whilst filling and bleeding air from your system without having to unplug EVERYTHING (particularly if it's an upgrade of an existing system) you can use a spare PSU to power the pump or use a power brick for a 2.5" IDE/3.5" IDE/SATA drive reader (typically 4-pin Molex on the cord from the power brick for 3.5" IDE drives, IDE->SATA converter plug to run SATA drives) to run the pump during filling/bleeding.

 

Whilst I was building Project: Monsuta V1.5, I was using a spare PSU to power-cycle the pump during the fill-and-bleed portion of the build then used the power brick for my IDE/SATA drive reader to run the pump during the 16hr leak test.

I don't have a spare psu, but the pump power connector is molex so couldn't I just have everything unplugged and just power the psu on and off to fill and have a 24hr leak test

 

@Lurick Do i have to use a jumper? The pump doesn't have to be connected to the mobo for power, only PWM. Also, do I need to be connected to a monitor before all this? I plan to first fill the elite loop with distilled water, drain it, then refill it up with some Mayhems Coolant I bought.

 

@Moress I'm not too worried about leaks, everything seems snug. Fingers crossed

So the only way to turn the PSU on is to jump two specific pins on the PSU 24-pin connector. You'll want to have everything but the pump disconnected from the power supply.

Ohhhhh, ok gotcha

@Lurick Also, my mobo has 8-pin and 4-pin ATX power connectors for the CPU but the power supply (850W) only has the 8-pin part and not the 4-Pin. Is this ok?

Usually there is an extra 4-pin on high end motherboards for extra heavy overclocks. Double check the manual but that's probably what that is.
