Hey Guys

Recently i come across a review status that CM Extreme 650W is not the true 650W. In fact it's 500W PSU but labelled 650W.

http://www.nokytech.net/coolermaster_maqui..._al-5938-a.html

Nokytech posted a review disclosing that CoolerMaster eXtreme 650W is a Seventeam 500W disguised in higher wattage

"According to an review site of Paris, when they uncovered CoolerMaster eXtreme Power 650W, was astonished on the finding that it's originally Seventeam's 500W(ST-500BKP) model. The institution had some negative opinions on the discovery.

"We are not the senseless users. Because of the heavy competition in PSU market, we cannot but doubt some manufactures use some means to earn more profits. This is not the very first event ever happened, but we are surprised to know that even the well-known brand like CoolerMaster does this kind of thing. They use a 500W model from the less well-known manufacturer and put on the label marking of their own 650W product and put it inside a good looking package. Besides, we doubt the truth of the existing PSU test reviews from some manufacturers. We are waiting for the responses form CoolerMaster."

eXtreme series isnt pure power thoguht?

, kinda new to me... anyway, CM PSU isn't do any good, even they say, it's true power, still... it's CoolerMaster, only "cool" in cooling solution, not PSU

of coursela...that why they rated extreme power(peak power) not true power.i own this one.i thought it was 650wx70%=455w.but from ur link it is 500w true power that mean my psu still have more power.thank for the info.glad to have 500w true power at good price.http://www.seventeam.com.tw/front/detail.asp?lang=eng&ID=98
correct me if wrong.

erm. im thinking about coolermaster extreme power 430w or either 380w. is it the same case with the above or does the above article confuse with efficiency only or wat?

yeahh...

Extream = not true power....

go for real or true power PSU.....

this 1 using a less known brand of PSU and relabel it, I doubt on its efficiency and reliability

In fact, seventeam is actually produced quality psu. cm, silvertone just re-label it. the code indicating who built it actually printed on the main pcb ( some psu hv more than 1 ). Just browse to jonnyguru's forum and you'll be suprised.

from jonnyguru forum
Silverstone Olympia OP1000

Seventeam, Etasis to name a few... those are good server grade PSU manufacturer

, even my ST56ZF also comes from Etasis...

Walau eh.....that mean CM is cheating the consumer man.....500W PSU they sell 650W price. Consumer paying for 650W but getting only 500W

Consumers should be smart enough to guess based on the price of the Extreme line compared to the other pure power prices
Pretty much expected if u ask me

U dont really pay for 650w price la..it's cheaper than true power 650w
Then wat u goin2 say about tagan 600w which is around rm700+?

what the h*ll!!i just wanna to buy cm 550watt..this make me think twice!

I think Extreme power 650W is not Pure 650W.... unless u go for Real Power series

4 sure..extream not same as true..
xtream pawar more cheap than pure pawar
but 4 this case..what a cheater!pay rm 650watt power get 500watt oly..what a fraudulences!!!

i think there are some sort of mis-leading. If inside components are 500W, they shouldn't label there 650W. They should label there 500W then let consumers to check themselves whether it's true power of not.

Well,in CM range,

Extreme Power=Peak Power,means,it will only supply 650W when in paek load time,but not continuesly,only peak (maybe 1 minute?)
(it's just like the Powerlogic magnum 450W)

Real Power/I-Green=Pure Power,supply continuesly power and more or higher effiency.

Well,they r not cheating ppl,as the Extreme never stated down it has real power supply....

Real power ker, True power ker, Extreme power ker... what's the difference? Don't buy brand.. buy what's inside.

ps: Seventeam 500W selling around RM230-260 niah

how to determine the inside??1 thats i know is comparing psu weight n just skodeng n snipe the psu heat sink either copper base or not..is it enough?correct me if im wrong.

Read reviews lor... read forums lor... since good reviews (like spcr) will open it up wat, then can see who makes it from the components, layout and heatsink design.

ps: nobody really uses copper heatsink for psu and this doesn't mean that the Coolermaster is a bad psu. It's just extra money paid for the black paint and coolermaster name mar
