Most powerful fanless PSU?

Well, I've found a few that provide a bit more than 520W. Might I ask what specs are you looking to run with that PSU. 520W is in most user cases quite enough.

Just in case I ever decide to add another passively cooled GPU and run them in SLI.

SeaSonic just announced a 700 & 100 (I think) fully passive psu.

Want to custom loop?  Ask me more if you are curious

Seasonic showed off their PRIME Fanless Titanium 600W in this year's Computex. Should be available in a few stores now, but a) it's hard to get and b) it's expensive.

Be nice to each other boys and girls. And don't cheap out on a power supply.

That's really cool, the extra 80W will be just enough for my needs. I don't really mind paying premium for absolute silence ;>

Just curious on what you need 600W for?

Why would you buy a fanless power supply for such a system?

Wouldn't the video cards have active cooling, wouldn't your water cooling (if you use) have fans that would make noise?

 

The power supply is passively cooled but you still have to move the air that heats up inside your case so you'd still have some noise produced. Not to mention, you may have coil whine and buzzing from the vrms of the video cards and the cpu.

 

You may be better off with a hybrid power supply, one that's completely passive below 200-250 watts and spin at very low rpm above that.

More headroom for running two 120W TDP GPUs and a 90-95W TDP CPU, in reality they consume more power than specified by TDP so a 600W would put me more at ease than a 520W.

TBH, you might be fine going with 520W provided you don't overclock and run everything at stock. Availability-wise, the fanless Seasonic 600W is only available in a few stores in Europe... so it may just be better to get a high-wattage power supply with a fan that doesn't turn on until it gets to a specific load.

Remember SATA3 7200rpm HDDs are very power hungry if you'll have a few installed then yes the 600w is advisable so you don't limit your upgrade path.

You can passively cool 120W GPUs no problem, especially when running them in open case to allow the hot air to rise freely. Of course the GPUs will have to be placed horizontally (my case allows that with a GPU riser) and not on top of each other, but rather next to each other (that's also not a big obstacle).

The Seasonic 520W reviews I read didn't have any coil whine issues, so i don't see why the 600W one would have them.

And no, I don't want any fans at all in my build.
