ehrmmmm ... Powerlogic is lousy ..... Ah the only choice to get is really CoolerMaster 550W SLI .... If no , need to import Acbel from somewhere .... Why good PSU is not sale in normal shop and very very hard to find  anyway ?

If u keen to get acbel,u can ask bombman frm bulk section. If CM or other brand, just ask mr moderno. Of coz, u got to pay for shipping, but trust me, both them are reliable and trustable. smile.gif

ACBEL LCD 500W ( 3.3v@26A 5v@28A 12V1@18A 12v2@21A 12v3@15A -12v@0.8A -5v@2A )

Moreover, stable rails.Very little flux during prime and superpi (+-0.03 is the max).

Well, my spec as in siggy.

QUOTE
IDLE ( 3.3v@4A 5v@5A 12V1@4A 12v2@0A 12v3@0A ) ???

On LOAD ( 3.3v@4A 5v@5A 12V1@4A 12v2@0A 12v3@0A ) ???


It's actually not the value used. Its's percentage of Ampere used.

e.g.
12v1 = 4, meaning, 4% of 12v1 is used, which translate, 4 / 100 x 18A = 0.72A is used.

Well, just think abt "Future Upgrades" dude. If u're willing to spend for another hundred when u upgrade ur pc, then, go for the lowest avvailable. But, do remember, future proc n gfx will consume more and more power. As for mine, I'm lucky enough to get 38W TDP opteron. 79GT is 90nm die which consume less power than its predecessor. which is around 51w idle. and 85w max full load.

Haha , come back after 1 hour of PSU test ... not actually test , just observations ...

RM 78.00 can get pure power PSU ????
No you can only get Real Power ... Not Pure Power .... Actually all the Cap cap capalang Brand PSU is not so "simply" put a Wattage on the casinng and that's it ... It normally said 400W MAX @ 25celcius or so .... That means under controled condition , the maximum possible Wattage output may be true .... ( unless they want to get Sue by someone .... business strategy smile.gif ) The thing may be true only under certain condition .. You know la ... How to keep PSU at 25Celcius at all times in Malaysia .... Unless Face to air cond la ... PSU very Temperature Peaky one ... Too high or too low , the wattage produce is diffrent ... Silicon Mosfet Performance may Vary ... I had notice those Ciplak PSU had very narrow ... 0 celcius to 40 celcius ... This is just to prevent people from said the PSU not UP to Standard .... But Good brand Like Acbel had working temp from -20 to 70 celcius (Silicon only in danger after 80Celcius ...) They dare to said that because they can go future ...
One more thing as long as their Multimeter Reads 400W at all possible perfect condition ... They can proudly Promote that their PSU is 400W .. aha Business strategy ... But for Good brand , their 400w may mean always above the minimum par of 400W regardless of temp .. unless extreme temp ...

Ah ... Mosfet Mosfet Mosfet ... crucial component in PSU ... anyway this dont cost much .... You can get 12V@50A if you want for only RM20 per mosfet ... But one thing that is important is the Voltage controller ... It control the switching of the Mosfet (hence called Switching PSU ) and it is very expensive if you get a Good PSU .. This High speed Switch controller determine your stability ... The faster the responds over the negative feedback , the more stable the current ... Acbel had a good Controller ... expecially the LCD version ... which vertually connected to the computer USB for better control of voltage flatuation .

Flatuation of ATRIX is terrible on the long term  when sudden load is induced not when the load is already induced .....
I observe this when i open the voltage Sensor for one hour and see what it flatuate .... Yes in short time you see nothing flatuate much ... But you put it as sensing once per second for 1 hour .. you will notice someting .... Dangerous indeed ... ATRIX can actually go as low as 1.26V and as High as 3.39V while the nominal is 3.33V ... this account to more than 5% of flatuation of the VCore ....  sweat.gif this goes to the 12V rail as well .... (thats while it had unstable Voltage regulation ... a power Mosfet but poor poor regulation ) No wonder it connot boot at the begining ... The voltage cannot be stablise in a sudden rise in demand ... anyway , if you say it can't run at REAL POWER 500W as stated .. you may be wrong ... If you give it enough time , It will Burst to the full power .... Thats why , after suceessful boot at first boot , you can actually stress the CPU without risking underpower ... (PRIME , SANDRA ... all the stress test can't trip this baby )

So , Not "the weight" that resemble the Power of PSU ... "ATRIX is very heavy la , heavy than those Ciplak one " but it is true for certain extent as the Powerful the Mosfet , the bigger the Heatsink ... but if you had high performance heatsink , then it will be smaller .... ( and those High performance 3 rail PSU have very smaller heat sink as inside is too crowed )

More research going on tonite until i had get my Acbel 550W...

Wow.... just like Owen Hargreaves. From zero to hero. Well, i guess, u just answered ur initial question on the 1st post.LoL

QUOTE
I don't think ATRIX will give Lousy power output .... as it have mention the total power Peak output will be at 1KW ....

Anyway , is that dealing with power ? or any other Factor , such as overpowered PC cannot be overclocked ?

Or should i Buy the RM4++ Cooler Master 550w SLI power supply ?

Hehe.... I & bombman told u already, 500w - 600w is just a gimmick, marketing strategy. The actual load is only around 100w - 200w. Whereas, P4 ( presscot ) mostly 250w max. Not the wattage, the stability is the most important, dude. smile.gif. Ok, let say, u go for acbel n bouhgt frm bombman, he suggest 500w, izzit? which is rm375. Plus shipping, rm20 (max), its RM395. What u get? Stabil rails n Lifetime Warranty n first class support n so on....so on.... smile.gif

Just my 2 cent

Never mind .. try one by one ... ha ha ...
If this is so ... my statement on Acbel Vs CM Vs ATRIX Vs ColorSit will be more credible .... whistling.gif

Wait till i upgrade my Mobo to GA 8I945P-G or 8N-SLI first ...

Ah , lots of PSU to sale now ...
