I'd be pretty pissed off right about now if I owned a Coolermaster PSU.

Here is an interesting one for you. Last month, CoolerMaster put out a video showing how some companies may be "hyping their PSU's actual abilities." The CM team used the chart below to explain "peak" power and "continuous" power and how their power supply differed from the generic unit.

In response to the video above, Tony Ou from SilverStone Technology had this to say:
 

Sad to see they were uninformed about power supply label and sadder still that they were trying to teach their users with this. To add further insult to injury, the Cooler Master Xtreme Power Plus 500 model they used in the video as an example happens to be a typical over-labeling PSUs with clear tell-tale signs:

To obtain safety certificates, the specification table and associate rating numbers on the power supply label must be accurate. The manufacturers are free to name the power supply any way they like however, so in this case, Cooler Master placed “500” next to the model name to suggest it as a 500W PSU (and sold as a 500W) as opposed to it being a 450W.

It’s a tough business competing in lower wattage range (500W & below) as every dollar counts so there are other types of over-labeling practices too. This is pretty bad for honest manufacturers that do not over-label on wattage and still have to compete on price. And to see Cooler Master trying to educate people with the wrong information, I just couldn’t stand it anymore.

Epic Fail much? 
I thought a large company like Coolermaster would actually be honest with their products. Was this the only model with the 'over-labelling' or are there more?

Oh I'm sure there are more.... Funny tho they label it "500" not 500w or 500 watts.... Loop hole anyone...?

Over labeling is everywhere to be honest.  It's worse when manufacturers overrate their PSUs but don't over-label it... this way you have no idea that it isn't as capable as it is advertised.

That is why we have 80 plus

I fail to see the point here with the 80 plus part...all that 80 plus means is that it will be able to give at least 80% of the wattage taken from the wall to the converted side of the power supply, IE no more than 20% conversion loss.
They could label it a 500, and only be able to give 300 to the pc with it pulling 325w from the wall, and it could still be a 80 plus certified psu as it has less than a 20% conversion loss.

It's more of misleading type than a over labeling. The 500 could mean different things.

We all know what it implies. That sort of answer sounds like a politician.

At least it's not this:

Our marketing team admittedly made a mistake here. As some Hard Forum members speculated, we did not involve an engineer in formulating that video and ended up with a seemingly disingenuous sounding explanation.
 
We pulled the video once we were made aware of this as we really have no reason to mislead end users. Our presence in this and many other forums should hopefully count for something when I say that we value your input and patronage.
 
We will be consulting with our Taiwan headquarters-based PSU engineer on an accurate explanation and you'll see a formal apology from our video staff.
 
We're also taking suggestions on any tests you would like to see. We have a well-equipped testing laboratory and would be happy to try to alleviate any concerns.
 
If you have any other questions or comments, you can direct them to me here, via PM, or via feedback@coolermaster.com.

Don't worry Nic you're not the first company to make a marketing mistake but I'm glad that you guys are trying to correct the situation quickly.

Nice of you to step up and address this. Now I can't speak for everyone, but as you mentioned, your presense on the forums does count for something with me. 

Everyone makes mistakes. It's how they are handled that shows a company's true colors. Well played Cooler Master, keep it up.

Interesting spot out on their 500w version.
 
The 750w 80 plus version actually shows "750w" and it can't even push 600w according to JonnyGuru's tests.

CoolerMaster has some great PSU's out on the market, don't know why they would stray off and do stuff like this with their reputation. It's just a recipe for disaster.

sadly, the psu side of the pc world is VERY misleading and always has been. for anyone who has been building for some years, this wont be news to you. the industry is not as bad as it was 5 or 6 years ago but its still happening to some degree. thankfully theirs guys like jonny guru who can destroy psu's properly so you can see what they actually can do!! thats why many guys went with PC P&C years ago because of their very strict standards, testing, and great performance. sadly, they were bought by ocz which scares the hell outta me!!

Well I think miss leading labeling is every where TBH.
The first time I bought a HDD it was a 10 Gig but it was only 9.7 gigs i called them up and complained and they explained that a portion was used for onboard software it used. I said them put enough space for the software so the consumer gets what was advertised!!!

its not cause of software...its because a gigabyte is 1024.

yep, Windows Detects a gig as 1024 and the hdd vendors represent a gig as 1000

While I may not support Cooler Master for their power supplies I would gladly purchase their cases over the competition anytime. Nothing wrong with other brands but CM always has what i'm looking for in a case at any price point.
 
I know they're working hard on improving their products and maybe they will come up with a design that will put them up with the likes of other regarded PSU brands.

Yep, just got my self a CM 690 II Advanced and I love it so far. Only case I didn't like from CM so far was the stacker, big case but barely any space inside. 

I'm using a CM 590 for the rig in my sig and it's good. Also bought a CM Storm Enforcer for my new rig and it's a fantastic case. For a $100 case it has a lot to offer.
