Not necessarily. I've seen some cap ayam PSUs that have 18A on it rails..

Let's compare..

Cap ayam: PowerLogic Magnum "450W"
+3.3V = 15A
+5V = 22A
+12V = 12A

True wattage: Enlight 420W (High Power OEM)
+3.3V = 30A
+5V = 40A
+12V = 18A

You can see the huge differences on every rail between the so-called "450W" and a real 420W PSU.

That Enlight PSU is pretty old, since the very early Pentium4 days.. Nowadays, due to change in board designs and power requirements most PSUs comes with bigger +12V rails. If you noticed the newer AcBel 470W above, it comes with dual +12V rails of 18A each. Some new "true power" PSUs have single +12V rails of 30A and sometimes up to 50A (and even much higher!).

Cap ayam with 18A on the +12V rail: E-View "480W"

However notice all the other rails are weaker than the Enlight 420W? So how can this be a "480W" PSU?

True wattage: Corsair VX 450W (single +12V rail)

Now do you notice the differences with the so-called "480W"/"450W" and this real 450W PSU?

There's also the "weight factor". Most "true power" PSUs are much heavier than their cap ayam counterparts. Different (and more) components inside..

@ bro lex...

for my glacial power 650A spec...this is can consider as good psu?..i confius abit 1 rail & 2 rail combination...

for your sample VX450W..this psu got 1 rail with big amps...my psu got 2 rail which each 20 & 25A...so i got 45A total is it?

Cooler Master's UCP 700W



80 Silver Certification ? Is it for real?
If its real, then i planning to get one. Although the price is abit , but in the long run my electric bills would be cheaper


Price: RM515 by Lalaman

wow....nice psu..it is modular one?

Its a good PSU. Yours is a dual rail design while the Corsair is a single rail design.. You have about total 42A on the +12V rails (use 504W / 12V) thus there is some balancing between the rails, theoretically it should be able to output total of 45A combined.

Yups, its is... Didn't you see the review link on the CoolerMaster product page? This one http://www.hkepc.com/1379#view

I'm afraid not..

thanks for your explanation

single rail is best for those wif large wattage like ss da750 wif 750w power...dual rail is like a backup rail....more rails means more stability..wel..there are many choices in the market..for my personal favour, i would like to go for xigmatek 650w and thermaltake qfan 650w...

What is about this Silver Certification??

yaa..what about 80 plus silver Certification?is good compare 80 plus only Certification?

Any 1 have any idea about the Gigabyte Odin Pro 550w and the Corsair VX550w?

Coz both in a near price range.

I'm confuse whether a strong single +12v rail is better or more +12v rail is better.

owh..btw the gigabyte psu is a modular cable psu.

plus got Blue LED fan...look nice...

I prefer modular since i can remove which cable i'm not use. It make airflow inside casing more spacious.

this is one advantages for modular psu..good cable management + air ventilation...

could u guys suggest which i should take?
a silverstone st400 or cooler master extreme power?

my budget is not more that 200..

get huntkeylo...sufficient kua....got for st400...dun go for extreme power....u wouldnt like it
