[SOLVED] How many watts do i need to run my radiators?

[bowtye]

Hey,
So basically I have gone a little.. well very very far on not changing my loop. I have a custom "Open loop" design in my pc and I have not changed the coolant in well over 3 years. My first time owning a liquid cooled pc, and honestly it just slipped my mind.

Long story short I'm looking to drain my loop take out my rez, and rads and clean them out with Mayhems Blitz Pro Cleaning Kit.

I don't want to take my power supply out of the case.. Just want to clean the rads and the rez outside of the case

My question.. simply put. How many watts would I logically need in a pwer supply to run the pump on the rez and clean out my rads? Would a 550 watt power supply suffice?

If given that you don't have industrial water pump in there, the common PC's open loop pump (high-end) needs only 23W (source). 550W PSU is more than enough.

Thanks for the input Aeacus! Much appreciated!
