Features and Delivery Contents
The delivery content is very generous and includes the modular connectors in a separate bag. In addition to the power cord and a set of screws, two anti-vibration frames are also included, along with the standard installation manual. A small card points out that the product has to be registered online to get the full 5-year of warranty.
The ATX 2.3-PSU is "SLI Ready" as usual in this power class. As a special feature, Cooler Master wants to focus on the heat sinks. These are aluminium sheets complemented with copper plates (which increase the total volume of the heat sink) on the semiconductors. The copper should help dissipate the heat much better. The PSU dimensions are 150 (w) x 86 (h) x 165 (l) mm and Cooler Master promotes the single +12V rail and a Japanese electrolytic capacitor for filtering. The product homepage emphasizes the protection-IC and the flat cables as interesting features; the cables are the same as in preceding models.
Cooler Master puts a lot of its efforts into the case of the PSU. Even though the grey surface and the stylistically confident aesthetics are not really part of our review criteria, the robust powder coating and the thickness of the material are nice features. The casing in particular should help shield other devices from electromagnetic interference. The rear side with the small honeycombed ventilation holes is also very sturdy and doesn't show the flex typical in other power supplies on this area. A small power switch is right next to the AC-inlet. The Cooler Master logo is visible on one side as well as on the fan grill.
Like previously mentioned the Silent Pro uses a single +12V rail, rated at 80 amps and measured generously. The smaller +3.3V and +5V rails are specified at 30A each and should deliver 183 watts, which will be considered in our load tests.

I have this PSU, it has been working ok but computer cannot go to sleep with this psu and fan is definitely audible even when no stress on hardware.Beenthere - Monday, September 6, 2010 - link
Don't care for the flat cables at all. They are a PITA and obstruct airflow. With quiet fans available there is little need for noise these days.hsew - Monday, September 6, 2010 - link
It's too bad we don't see more PSU reviews from this site more often. This is one of the few sites that properly tests PSUs.redwolfe98 - Tuesday, September 7, 2010 - link
every review of a "cooler master" power supply that i read mentions some defect..having half of the air-intake blocked is stupid..

Power Supplies this strong are made for CF and SLI gymnastics, right? So if you've got 2 or 3 high end graphic cards stacked how are you going to cool them? Passively?....I don't think so. Now, I dont know how load those coolers are going to be but one can bet they're gonna be loader than 20dba......so this fuss about 20dba being too load is irrelevant or should we say ridiculous...If you're building audio workstation...that's another story....but you're not gonna need 1000W, thats for sure...

PS.Who needs 1000W PS anyway.... 99,9999% of people get nothing with it but bragging rights...
My 625W Enermax is more than I will ever need and even with that I often ask myself if I ever am gonna need that much power.... taking into consideration that my i7 920 and HD 4870 are not exactly 'power saving components'....

Agreed. 1kW is far too much for most PCs. One of my PCs has 380W PS and the other has 330W PS. Both have a video card installed. If you have only one video card (read: 90% of PC owners), you don't need over 350W.Martin Kaffei - Tuesday, September 7, 2010 - link
Hi,for my next review I got an Antec Earth Watts Green 380W. Hope, you'll like it.
