Wanna ask something, the strider 560W really good? I am still thinking whether to get Modular PSU or just get a good and stable PSU enough... btw, how is the cable management for the strider 560W from your experience? Easy or will mess with cacing around...? I know different casing will have different cable management, just wanna know till how good it can be managed... icon_rolleyes.gif

Well, this is my personal oppinion. In term of pricing, there is no doubt this is a good buy. Why?I think its hard to get a good, rock solid 560Watt PSU for as low as RM330 (if you know how to bargain) in the first place. Most of them cost higher than this..

2ndly, this PSU have rock solid review. I do not know how to judge a PSU well as i only read it on reviews but from what i can see in my bios, the voltage does not fluctuate as much as my previous CM which seems like a good sign. Anyway, i got no doubt this is a very good, rock solid PSU in the first place considering those great review it gets..

Cable management wise, it really depends on your skill as well as the casing you use. If you really wanted to know more, try searching in the Cable Management Section and check out mine there using the ST56F. I am not a great cable management person but using the LL and SS, i think its easier than my previous CM. Not to mention some of the cable is pre-sleeved so it will look better than CM ones...

Just go to cable management thread to see your photo...the cable is pre-sleeved... nod.gif I just afraid it will not be easy to manage in my CM Centurion 532... sweat.gif anywqay, thanks for the info... notworthy.gif icon_rolleyes.gif

How much should I spend if I want a quiet PSU? My budget should be below RM300. I'm thinking of CM Real Power but seems there's not a lot of ppl recommend it....
I'm not doing OC, just normal gaming...

Yea, thats why i say some parts are not sleeved properly. Besides that, i personally change the molex connector to those Vantec ones for easy removal. Those originally came was normal molex connectors...

Yes, no problem at all.Even 24 pin one can fit into a 20pin mobo. All you need is a converter..

CM Real Power is good but wont be the best available.The price is cheap but not that recommended for OCing. If you are not OCing, I guess CM Real Power should be fine..



Anyone knows where to get 4pin --> 8pin converter for PSU?

No problem at all as it is come with 20 + 4 pin isn't it... you just plug in the 20 pin, left the 4 pin out... icon_rolleyes.gif

any PSU which is cheap below rm200, can support a single 8800GTS 320MB? Using AM2 3600 EE edition, 2 HDD, 2 casing fans, 1 DVD burner. Or is that CM extremepower 430W can support it? I am confuse with 12V rails. Most budget PSU only offer <20A in single 12V rail, but when dual rail combined, it can be 30-38A, which case is recommended? Single rail with 26A or double rail with 30A ?

For 8800 I recommand 450W real power but all 450W is RM200 and above. You can try Coolermaster Real Power 450W which is just a bit over RM200, around RM220 I believe.

Your system estimate needs real power 350W with 25A on 12V rail. You might ask just 350W why needs 450W? It is just an estimate of power usage, you should get higher than usage.

Particularly because to get that high efficiency rating of 80% even at peak load.

Ok Guys one quick question.

Corsair 620w Modular / Silverstone 560w Strider / Tagan 480w EasyCon / Acbel 550w Real

which one is better?

Tagan and Corsair is modular and it looks good interms and packaging and design but dunno wether good or not.. Tagan is the best i think for cabling.. but expensive

The best is the Corsair. A whoopin 50a on the 12v rails and considering it is modular, thats pretty damn awesome. Its not too expensive anyways, if you have the money... definitely go for it.

Guys, need to ask something..

People are stressing on getting a single +12V rail would be better etc etc. However, if having single rail is better, why is there anything such as multi rail?Is multi rail really useless or it is meant for something else?

Ok, i have seen Silverstone PSU that are high end mostly are using Single Rail while the lower ones are using Multi Rail which is also equivalent to Sinlge Is Better.

But, look at other Reliable PSU like Tagan. Even their top end PSU are using Multi Rail and they are claiming is stable and reliable. Coming from Tagan, i think thats quite assuring as well..

So, in which case is having multi rail is better and which is having single rail is better?Or is Multi Rail no good at all?

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.


Something I found online. Need to check proper and calculate the power before concluding this statement above.

2. 2x1gb ddr2 ram
3. 1 dvd burner
4. 2 hdd (sata2)
4. 7900gs or higher.

ive been drooling over ENERMAX 400Watt LIBERTY (rm350-cycom)
but the price is out of my budget right now.
then i see this ENERMAX 350Watt FMA Iron (rm190-cycom).

shud i take the fma iron now, and mayb buy liberty in the future for futher upgrade?
fma iron ok or not? cant find any review sweat.gif
