Looks like Enermax's reply to Seasonic :) Looking foward to see SPCR review! :D

Looks interesting and they do go as low as 500W as opposed to 650W for Seasonic. Would be hard to beat Seasonic's fanless operation at lower wattages though. I wonder if Enermax will also operate fanless below 150W.

The specs indicate that the minimum fan speed is 330 RPM, even at "0" output. A 330 RPM fan is so close to completely silent that I doubt the difference with the X-series is material.


Overall it looks great! The internal pictures look similar to the Seasonic ("Where did my power supply go??"). The 500W model should have slightly better efficiency for a typical PC than the Seasonic, but the overall efficiency curve looks like the X-series.

Hopefully these new models will bring some sanity to the pricing for these high-efficiency PSUs. I too am looking forward to Mike's review! :D

Well, they're not really comparable to the Seasonic X, as that unit has a totally different layout that I'm pretty sure will be much more efficient at low loads (below 20%), plus it's designed to supply more total power. The Enermax one will probably cost as much or more than the Seasonic at the higher wattage, as they don't have to interfere with the current Pro/Modu 82+ lineups: I don't even hope for them to be price/performance winner units!

Depends. My PSU also has one really slow moving fan on very low loads (<150W) it seems, yet at the slow turning speed it seems there is an irritating wobbling fan noise. You can barely hear the air movement, but you can definitely hear the irritating fan bearing which, no matter how I try and isolate it from the chassis, still drives me insane.

I wonder if the ugly gold color scheme is going to be a common theme among 80Plus Gold certified PSUs. :lol:

Other than that, looks pretty nice. Hopefully they plan to send a review sample to SPCR.

It's got bling. :D The next version will have spinners on the fans.

Also, the fan in Modu87+ is 140mm big, so it's going to be louder than 120mm in Seasonic.

At least it's a 140mm and not the ever stupid 135mm ... but then I see the spec says 13.9cm so are we looking at another hack job to get a proper 140mm in place?

140mm fans have 135mm impellers, there's no "conspiration" to produce strange fans. It simply depends on what the manufacturers want to measure. :wink:

There's nothing that leads to such a drastic conclusion, fan size is not directly dependant on noise, only on noise/airflow ratio. And the Seasonic uses a quite fast-spinning fan to keep it cold at higher loads and temperatures.

:) Well there's something I didn't know. I'll get out the calipers and have a measure.

Review at Hardwaresecrets

Review of Modu 87+ 700W :
http://www.hardwaresecrets.com/article/900

Peak efficiency at c. 140W - 290W (120V mains)
Does not quite reach 87% at full load of 700W with high room temp
Low ripple & noise

Not a single mention about acoustic noise. Sigh.

The Anandtech review does address noise, and they are very quiet.

AnandTech says
In the case of the Modu87+ and Pro87+ for example Enermax wanted a larger fan; 140mm is the largest possible in an ATX power supply today and it's already patented, so Enermax decided to make a 139mm fan themselves.

You can patent just about anything these days. :p

In the same review you can read that enermax didn`t use a pwm fan because using it in a psu is also patented..

Today I also saw the Anandtech review including fan speed and noise testing. The fan speed can be as low as 330rpm in idle and even 900rpm at full load, though it's a 14cm fan and the noise can be larger given the same speed. Can't wait for SPCR's review, since Enermax has a 500W model suitable for silencer's requirements.
