Why need 3 12V ? What so good or special about  3 x 12V? Anybody can tell?

eh... TS... can u give better posting than a single line?

i was hoping for more information when i saw this thread on the thread listing.. and what i can see is 1 line of sentence

yup
start ur topic with more informatic will helpful
i dun think anything special there wif 3 12V rails
but i'm more interested how strong each of those rails

@TS, i did some "research" and read some, and from what i'm understand that, Enermax claimed this PSU is on 3 separated rails, unlike normal multi-rail PSU is originally distributed from large single rail to multi-rail - please correct me if i'm wrong on this...

There's probably no reason to buy it if your pc won't produce the amount of power it supports.

I have an INFINITI 620watts.

It has only one transformer. Shared by three "virtual" 12v rails. So it's not really multirails.

According to the label (enermax is usually pretty reliable on the spec department, but dont trust everything 100%):

28amps for 12v1 and 12v2, 30amps for 12v3.

total 12v amps = 52amps

It has OCP, whether all the 12v rails share a unified OCP of 52amps, is yet to be reveiled, enermax wont talk. 

But IT CAN RUN dual 8800GTX SLI. It has been tested by many users.

yup yup...good modular cable mgmt!

i dropped by low yat tat day...saw some dealers having 1st yr 1to1 exchange for Enermax FMA series!!!  with total warranty period of 3 yrs~ 

3. DON'T LOSE POWER WITH MODULAR PLUGS
Due to their look, convenience, and cost savings for manufacturers, modular plugs have become a popular power supply feature. Unfortunately, there has been little or no discussion of the impact of this feature on overall performance and reliability. The fact is, modular plugs limit power by adding to electrical resistance. The voltage drop can be as much as would occur in 2 feet of standard wire. Worse yet, modular plugs utilize delicate pins that can easily loosen, corrode, and burn, creating the potential for a major system failure. That's why professional system builders specify uninterrupted wire!

8. ARE MULTIPLE 12-VOLT RAILS BETTER THAN A SINGLE 12-VOLT RAIL?
With all the hype about multiple 12-volt rails (ads claim that two rails is better than one, five is better than four, etc.), you'd think it was a better design. Unfortunately, it's not!

Here are the facts: A large, single 12-volt rail (without a 240VA limit) can transfer 100% of the 12-volt output from the PSU to the computer, while a multi-rail 12-volt design has distribution losses of up to 30% of the power supply's rating. Those losses occur because power literally gets "trapped" on under-utilized rails. For example, if the 12-volt rail that powers the CPU is rated for 17 amps and the CPU only uses 7A, the remaining 10A is unusable, since it is isolated from the rest of the system.

Since the maximum current from any one 12-volt rail of a multiple-rail PSU is limited to 20 amps (240VA / 12 volts = 20 amps), PCs with high-performance components that draw over 20 amps from the same rail are subject to over-current shutdowns. With power requirements for multiple processors and graphics cards continuing to grow, the multiple-rail design, with its 240VA limit per rail, is basically obsolete.

PC Power and Cooling is once again leading the industry. All of our power supplies now feature a large, single 12-volt rail. The design is favored by major processor and graphics companies, complies with EPS12V specs (the 240VA limit is not a requirement) and is approved by all major safety agencies such as UL and TUV.

Have fun hoping that your Enermax isn't one of the dodgy ones which I've come across soo many times. And the truth about modular cable management?

Here: http://www.pcpower.com/technology/myths/

oh yeah???where did u ENCOUNTER such dodgy ones then?

so now the best bet to go with is a single rail non modular PSUs?

oh yeah???where did u ENCOUNTER such dodgy ones then?

3 FMA's. 2 Libertys, 1 Coolergiant, all exhibiting stabillity criterion of more then 0.5. And not to mention the local distributor blaming it on user error

You're talking like that to almostthere whose in real life is a hardware reviewer in a famous website?

bro almostthere,when only can u know there is such bad on enermax?when full load the psu or syok syok kena the problem?

and also shawty himself. Brapa PSU Enermax ko buat hal harituh?

ohh .. god .. sHAwTY ..

Enermax PSU is really so poor ??? i thought they manfacturer their own PSU ..?? Even with own production plant established for over years but the product durability not promising ??

anwyay bro u OC a lot with both PSU ?? i owned 500 watts liberty but it last until the lightning stike .. which was around 6 months above..

hmm.. with all these feedback here .. what would be the best PSU .. since Enermax, Tagan and Cooler Master didn't work out well ..

Two PSU's, both are Enermax PSU's.

One Enermax Liberty 620W [ni takpela, murah sikit, mati dalam tiga bulan ]
One Enermax Galaxy 1KW [psu mahal pun mati dalam masa tiga bulan? ]

So conclusion:
No more Enermax for me, no sir.

Learn more about him before you start saying something that sounds like you're stating that almostthere is a newbie.
Yerp.
