Fanless 1000w+ PSU

Matirre · Jul 27, 2017

Hey!

I'm looking for a fanless power supply solution for my very overkill gaming/workstation pc.

The plan is to have the CPU, GPUs, mobo, ram, on a watercooling loop. I won't be using radiators but instead the new Alphacool Eiszeit 2000 water chiller, and stuff it away in another room to eliminate noise. It will enable me to go sub ambient, however i will not go very cold because of condensation.

My goal with this build is to have 0 moving parts, not because its necessary but because its a fun idea.

The power supply therefore needs to be silent and have no moving parts. I have seen fanless psu's however, they are only 550w max. My rig needs more than that. (1080ti SLI, I9 7950x, )

Would the best option be 2 550w psu's or have anyone found a 1000+w fanless psu?

Don't say that i should buy a semi-passive psu please. It needs to be fanless.

Doesn't exist.

2 550w psus dont work

The end.

You should still put a fan in the front of the case and rear to help move air through it. that ram and motherboard still need air movement to help keep things cool even if they are 500rpm fans.

If you want complete quite while computing then get long monitor and usb cables and put the computer in another room so all you have is monitor, KB/Mouse at your desk.

Those don't exist. This is the highest wattage fanless PSU

Ok..... Do you think i could buy i 1000w psu and remove the fan? Would it overheat? Do you have any other solution to my problem?

Yes ik but what should i do? Is there any other solution?

Matirre :

Removing the fan will probably damage some other part of the PSU, and those fans are there for a reason. It will most likely overheat, and removing a vital part of a PSU is probably the last thing you want to do to get a working PC.

1000w+ PSUs will need their fans. You won't be able to have a fully unmoving PC.

Matirre :

what do you think the purpose of a fan in the PSU is for?

faalin :

Ram and mobo is watercooled. I really like to show of my pc so that isn't an option. I want to move away all of the heat to another room, do the cooling there and keep my pc in my gaming room for aesthetics

evga supernova 1600 watt p2 has a fan, but in eco mode unless you push it harder than my i7 5930 at 4.6 ghz and sli 1080s at 2.2 ghz the fan will never come on. even when im under full load benching the psu doesnt get hot enough for the fan to turn on

"Ok..... Do you think i could buy i 1000w psu and remove the fan?"

Definitely not.

"Do you have any other solution to my problem?"

Forget about having a fanless PSU or build a more modest system that only needs that Seasonic 520-watt one.

2 PSUs actually do work, the problem would be getting a case that supports 2 PSUs.
Simply put, 1000Ws fanless will overheat.
2 1080tis are also going to seriously overheat.

But 550ws is a bit low of an i9 1080ti system as well.

BUT, higher end Seasonic (prime titanium) PSUs with fans, don't always run the fan unless they're drawing enough power to need to turn it on.

Obviously cooling it. Are there any psu waterblocks out there? i have seen waterblocks for 500w psus but as thats not enough...

You won't be able to buy one off the shelf. There's not enough demand for anyone to stock it so there won't be any manufacturers building them.

You can possibly get these people to design and build one for you. It won't be cheap though.

Depending on how far it is to the other room, you might be able to put the power supply there and run cables to the PC. That's going to require a lot of shielding for the cables so they don't pick up EMI/EFI. It will also require heavier wire than normal so you'll have to make your own cables.

It's just a question of how much money you want to throw at it.

James Mason :

that won't be a problem as i will probably wall mount the components for looks. How would i set up 2 psus???

Matirre · Jul 27, 2017

thx1138v2 :

I have experience with building my own cables so that isn't a problem... What kind of shielding are we talking about and where can i buy it?

James Mason · Jul 27, 2017

Matirre :

You connect the CPU and 1 GPU to 1 PSU, and the other GPU to the other PSU. You probably need something like this Power Combo (http://www.phanteks.com/PH-PWCOB.html) to get the power on signal to both PSUs. (will also split the CPU/motherboard load between them)
Wall mount that with a compressor cooler in another room may be a bad idea, because after a certain length of cables (like to another room) pressure needed to move the liquid may not be enough, especially if it has to push it up like 5-6 feet for a wall mounted setup. as well as like 15-30 feet worth of tubing between wherever it is and the computer.

Your "no moving parts" idea will actually have far more points of failure though from custom loop watercooling.

The Eizeit has a built in pump that has a head pressure of 10m (30ft) and has a flow rate of up to 600l/h. Alphacool themselves say that you can put it in the basement and have you computer upstairs. I will put the computer and the Eizeit on the same level so that there is minimal head pressure needed.

Thanks for the phanteks link however!
