Nice, I have been wanting a liquid cooled power supply for a while,
My current Seasonic powersupply is quiet, but when gaming the noisiest thing from the whole PC is the fan in the power supply.
I will be watching out for these becoming available
Eh... there's plenty of liquid cooled ATX PSUs?!? I already had one by SilentMaxx over a decade ago. Acceptable marketing lies I guess.
Link please. Because all I see from SilentMaxx are passive air cooled PSUsQuote:

You could have tried like... googling it. Took me 2 Seconds. http://www.aquatuning.de/gehaeuse-und-hardware/netzteile/netzteile-wassergekuehlt/5815/silentmaxx-fanless-watercooled-600w-10/8mm-g1/8Quote:

A 600W Titanium supply running at full load is supposed have a min of 94% efficient so would waste 38W. At 50% load it should be 96% efficient, so wasting 12.5W. As long the design is able to disperse those 13W passively, there is no need to run a fan. And even gaming with a single high-end and a modest overclock the expected system load is about 350W (Hexus' most recent 1080Ti review with a i7-6700K @ 4.4GHz), any PSU fan wouldn't have to run much. (350W at 96% is still only 15W waste heat.)
Koolance was quite modest about their claim, back in 2001.

Koolance also had one http://koolance.com/1300-1700w-liquid-cooled-power-supply
The worlds first will have an asterisk somewhere that says "*worlds first in 2017" i bet xD
Apparently FSPA make the psu if various big brands, unfortunately FSP is the only brand of psu I've had fail
I think they might be banking on the "mass produced" part of the claim ("the world's first mass produced liquid cooled PSU," ), though there's not way to really know how many have been produced of any of these models...
Ok... Looking at the link to the FSP/Bitspower page, I see "World's Only" in their claim, which is totally different then "first." They are claiming it is patented, so clearly they did something different, but they don't say what. I'd love to see a teardown, but right now, their claim is either BS or they are saying something strange like "no one else is currently mass producing these, so we are the only ones." Which is pretty silly...Quote:

Still, the market will decide.
And with regards to radiators and fans being noisy I totally disagree, I have had several full custom loops and have never had very noisy fans, but I do use Hardware Labs 30mm thick radiators that are designed to be especially effective with slow turning fans. It is the thicker radiators where I have found the fans need to turn faster and therefore noisier.
But I also use multiple radiators because if you have more radiators you have more surface area to dissipate the heat, so long as you have a powerful enough pump setup it can be very quiet.
I have a watercooled 5930K with 2 Maxwell Titan X's, I cool them through two 420mm (3 x 140mm) and a 140mm radiators, I use 2 D5 Vario pumps on a moderate setting, I have all my fans running at about 750rpm so they are almost silent, this is why when the PSU fan spins up I can clearly hear it over the whole system. When gaming my temps are CPU at 50'C and both graphics cards at 40 to 42'C.
If one of these PSU's works like it should then in my case I could remove the one noise that annoys me, but for me the whole reason I watercool is for my PC to be silent.
Do you play games on silent ? I know it seems like a smartass question, but I'm serious, I'm wondering why you even hear fans while gaming
I don't hear a damn thing over my headset. I'm also wondering why I would consider watercooling a PSU, sounds a bit like tempting fate to me.Quote:

Honestly? I quite often do. In a lot of strategy games I play the sound is pretty much pointless (and sometimes just plain annoying). But it also varies on where I live and what time of day. If there's a lot of traffic noise, then my PC is barely audible even with the fans on high. In a quiet cul de sac it's literally the only thing audible in the building.Quote:

Don't worry. Figured that you're just a troll.Quote:

I've never looked into custom loops so I can see how you could spec fans with a lower noise profile but I can't see how you get around the pump noise?
the key is not to get a psu that just about supplies what you need i always get one that provides least 30% more output than i require . that way the components are not running at their voltage / thermal limit , thereby reducing heat and stress on the components which means the fan can run slower. it also means it will last longer and be more stable in the long run. and i think water cooling on a psu is a bad idea anyway. water cooling with 12vdc and 5vdc is fine as you only kill components not your self, but where there is potential for 240vac mains to get into the mix , that's a bad idea.
Liquid cooled power supply?
Cant imagine anything more foolish than directly pumping liquid through the element of the system that is responsible for transforming mains power to DC.
I'm sure there is loads of examples of it done in enterprise and industrial settings...but...no.
That's not really true as efficiency is fairly constant:Quote:

Let's assume your overspec'ed PSU is running at 50% load vs 100%. The biggest difference between 50% and 100% is actually for Platinum (94% vs 90%) but in general it is 3%.
So take a 1000W Platinum supply, at 50% load it's going to waste ~32W of heat. A 500W Platinum supply running at 100% is going to waste ~55W. Not that big a difference. But more realistically, 1000W Platinum is probably going to cost more than a 500W Titanium, so the comparison is more likely to be between 100% Titanium vs 50% Platinum which co-incidentally is both 94% efficiency so 32W of heat.
Basically, my point is that the 80 Plus certification takes heat into account (since inefficiency in a PSU is heat), and therefore the supplies do not drop off when running near their limits. Of course, most Platinum and Titanium supplies could probably run past their rated at reduced efficiency if they didn't have overcurrent protection. Then they probably would run extra hot and reduce their lifespan.
Decent pumps aren't really that noisy. Most pump "noise" is actually vibration, which gets amplified if it's rigidly coupled to big chunks of metal (e.g. the case). This is quite easy to get around with by isolating the pump using, for example, rubber grommets or mounting kits which are widely available. The pump in my system is barely audible in a completely silent room (about the same noise as a modern hard drive) and completely inaudible with the case door closed.Quote:

Yeah, like, er... how almost all coal, nuclear, and hydroelectric power plants work?Quote:

You could, hypothetically, have the pump isolated from the CPU waterblock by rubber mounts and a couple of short sections of rubber tubing. So what is now one block bolted to the CPU (that contains the pump and waterblock) would be two blocks with a bit of wiggle possible between them. It also has the potential for hilarity if you manage to hit the resonant frequency of the motherboard on the standoffs :laugh:
