Cooler Master X Silent Edge Platinum 850 W
- Thread starter suvirintojas
- Start date
If you want a silent PSU you're (imo) just better off getting a very premium power supply with proper fancontrol. Get something A++ Cybenetics rated and preferable something overkill or, even better, check the profile as reviewed by Cybenetics and base it off that.
One good example is the Cooler Master X Silent Max Platinum 1300, https://www.cybenetics.com/evaluations/psus/2493/.
This thing is silent until you pull 1150W or so and will handle anything you throw at it for about the same price.

I doubt it run silent till 1150W unless taking advantage of the computer case fan.
I mean it states this has been tested at an ambient temperature of 30-32°C but not for how long.
30°C is very high for an ambient temperature considering 20°C is more realistic.
But they say nothing about for how long so... question mark?

As jonneyGURU said
"Whereas, Zero RPM fan mode will wait until there is so much heat to dissipate, the fan kicks on at 400W and the air coming out of the back can be used to melt heatshrink tubing."

TechPowerUp is Hiring a Power Supply (PSU) Reviewer
Thermal energies make it easier to overcome the diode drop, and so increase efficiency. voltage - Why does temperature modify the characteristics of a diode? - Electrical Engineering Stack Exchange So, a hot diode has higher efficiency. Your attention is focused on wrong quadrant :roll...

30c is normal for a chamber, when I ran two walk in chambers they stayed at 30c simply from the lights (pre-LED) even with the door wide open
via cybenetics
We measure the fan's noise from one meter away, inside a hemi-anechoic chamber whose internals are entirely covered in specialized soundproofing material. Background noise inside the chamber is kept below 6 dB(A) during testing, with humidity being close to 50%. We should stress however that to obtain the fan speed results we apply the same conditions with our efficiency readings (operating temperature >30 °C) and we take the fan's output speed throughout the PSU's entire operating range. This allows us to calculate the unit's overall noise output and provide the corresponding Lambda certification.
I have bought this PSU in the EU (1100W) variant. Yes, it is ultra niche and also overly expensive. It is a dumb buy. It is also completely inhouse designed and manufactured in Taiwan, a cooperation effort of CoolerMaster and Infineon.
Feeds Core 9 Ultra 285K, RTX 5090 (on the way, there is a substitute inside currently), 21 fans at ultra low RPMs, two D5s and an array of five Optane 905P drives. The machine is inaudible during the usual work and gaming and extremely silent during ultra heavy loads. I have developed a strong hatred for PSUs that do this "swoosh" sound every time a fan spins up. This is what I was looking for.
Very happy with the result, would buy again.
P.S.: My friend has this SeaSonic Fanless 520W PSU that he owns from maybe 2013-14. Thing has endured 10+ years of everyday service under multiple configurations, currently on the most recent build with Ryzen 7 9700X + RTX 4070Ti Super. I would like to stick to my CM in a similar way, given the standards or connectors will not change.

This is an impressive aspect.
Despite the ripple, this is an excellent performing PSU, even at that price.

I've actually bought the 1100W unit.
I had the Seasonic 600W fanless before and I've been waiting for a passively cooled ATX 3.x PSU to replace it so I'm not at razor's edge with my 4090. The 700W fanless wasn't a worthwhile upgrade in that situation.
I see two usecases for a PSU like this:
1) Enthusiasts like me who have a custom watercooling loop that allows for a dead silent system at any load (yes, I managed to silence the pump)
2) Hardware reviewers who do noise measurements in an anechoic chamber. Being certain that there is no PSU fan that could possibly kick on is useful in that scenario
Yes, it's ultra niche. Which is part of why it's so darn expensive, because there's no production at scale. I think that's perfectly fine, though - I'm just glad that it exists at all.
I expect that there's significant overlap between people who buy this and people who buy the MoRa IV 600 (though I'm sticking to my MoRa 3 420... for now...)
It's a small change, but it's there.

Not quite. They also replaced some of the heat sinks with larger versions that'd collide with the fan on the 1300W.

Alternate has been offering the 850W version for preorder for 289€ since the middle of march now...
www.alternate.de
They also had the 1100W for 299€, but that's listed as out of stock now.
www.alternate.de
Meanwhile, the 1300W actively cooled version is still available for 499€. (I'm not actually sure if it's selling... it doesn't really have a standout feature the way the passive variants do, though it's still the quietest 1300W on the market.)
I wonder what's with the price drop? Is Alternate doing something on their own, or did Cooler Master decide that they've recouped enough of their development costs and are willing to try and trade margin for greater sales volume now?
