Being new to water cooling, I'm curious what the current thinking is on water cooling power supplies? Looking around the online shops I've seen the odd WC'd PSU but they don't seem like a popular item...just wondering why?
 
They're just a waste of money and not needed............... :eek: But that's just MHO.............. :cool:
 
There is a very limited selection of water cooled PSU's out there.. I know that I wouldn't buy most of the WC'ed PSU's out there just because I wouldn't buy the specific power supply even if it wasn't water cooled.
 
there has been like one PSU designed from the ground up as water cooled that Im aware of
there simply isnt that great a market, and retrofitted designs are labor intensive and a compromise

in short there are no "modern" high quality H2O PSUs Im aware of

as far as they don't need it
I wouldnt say that, in a topend workstation loaded for bear you just might need to dump several hundred watts of heat

but most of the development has gone into increasing PSU efficiency (80% or better these days)

So which one is designed from the ground up? What do you think of the SilentMaxx PSU?

as far as that SilentMaxx I dont know much about it

If I was going to do a water cooled PSU Id do it like this

adapted to a PCP&C 510

Careful there Ice Czar, dont tempt TN to watercool her PCP&C 510 or else she will never finish her case mod.


As for watercooling PSUs, it isn't really needed except for the really high end (600W plus) models. The PCP&C would fall into the 600W plus category because it is rated very conservatively unlike 99.9% of the power supplies on the market.

Unless you really need all that power stick with a nice 80% effeciency model. My Seasonic S12-500w is silent, at least you cant hear it above any thing else in my system. The loudest thing in my system is the stock AMD fan on low, my two 120mm are running at absolute lowest speed.
 
must have been a different one or the silentmaxx series is an outgrowth of the one Im thinking of (I didnt bother translating yesterday)
there was a German Designed , but low power and old school ATX12V v1.3 (NOT A HYBRID) that had been designed from the ground up as an H2O PSU
 
My friend was looking for a WCed PSU also, but he uses 1/2" tubing. Guess he's just S.O.L?

IIRC the SilentMaxx water cooled PSU has 1/4 BSPP threads so 1/2" ID tubing is probably dooable.
 
Has anyone tried the Silentmaxx? Does it have good quality? Are there any other alternatives that are under $250?

If you're going to spend that much on a psu, why not get the PC P&C 510 for $229. It's the best psu money can buy, except for the pc p&c 850. :D

$250 for a water cooled PSU is not too unreasonable if you look at the price of various other water cooled devices. The PCP&C is not what I would call quiet and you can see here the boat prop they decided to use for a fan. :eek:

the problem with cooling and quieting PSUs, is that the solution they have to offer you is confined to the PSU enclosure itself, whereas with a little creativity and ductwork you have a much deeper potential ;)

for starters, dont exhaust the whole case through the PSU
I could remove the fan from my PCP&C altogether, not that it would make much difference when it comes to how loud the computer is, has something to do with those 3 120mm jet engines in the middle of the 4U :p

(the one on the far right force feeds a duct to the PSU and there is just a DVDRW, DigiDoc & FDD upstream of it)
 
I guess my main problem with wc'd psu's is, thats the LAST place you ever want a leak to happen. Water in the powerplant of 500w and 35a....nah, I don't mind the little bit of noise at all.
 
agreed which is why I linked a mineral oil filled PSU that then cools the oil with a waterblock ;)

it also simplifies creating a great enough temperature differential to all various heatsources in the supply.

another option for an intermidiate transfer medium would be flourinert (which comes in a wide variety of boiling temperatures)
 
That I believe is the advantage of the SilentMaxx (Aqua Computer Cool Current) as the water never reaches the inside of the PSU.
 
the bad part being the heat transfer effciency of gases vs liquids
"some" of the heatsources in the SilentMaxx are obviously connected through conduction to the waterblock, some are cooled by convection to air, how effciently I have no idea, how good the supply is I also have no idea.


we could start up a collection, buy one and send it to Oleg though :p

i've WC a couple of enermax PSU, and think it's worth it for a totally silent rig, or an air tight rig, but i still had to have some airflow through the PSU to cool all the other parts. I would kill for a PCP&C SLI 510 designed for WC from the ground up.........
