Im planning to built a total silent pc but the power supply seem like will bring the most noises. Im planning to water cooled my PSU which I change the 2 main heat sink in PSU to copper and let water flow through it. I want to ask, if I have enough copper and ensure no leaking of water, if there any problem for this project? Is water enough to cool the PSU down? Any1 have experience on this?

watercool psu?do u meant like open the psu case then put some waterblock?

PSUs don't produce much heat unless you are having an unefficient PSU... Usually a 80+ Gold/Platinium PSU with a wattage below 600W (can someone confirm?) produce so little heat that you could go fanless with it...

So, go for fanless PSUs if you want 0 noise... water cooling a psu is almost impossible...

yup

remove the heatsink n change to water block,wad water block r u using?
Juz make sure no leakage

its very risky man.once got leakage than that's it. if ur room is air conditioned why dont u just remove the psu fan since its not producing much heat, but need to be gold, 80+, certified and very good psu indeed

An example of a fanless PSU

walao... that power direct connect to ur current... too risky
pointless to watercooling a psu

Wah..water cooled psu??
Never heard about that

koolance got make such psu...

OP, not sure if you are still looking for it, but koolance has a 1000w unit.

Do take note that Koolance recommends that you use a water cooling system capable of dissipating at least 200w of heat for the PSU alone. Or you could use the Exos system.

Good luck.
