Well, in my honest opinion, no. There are better alternatives out there e.g the Silverstone Strider Plus 600W at RM279 and the Xigmatek Bronze 600W at RM289, or the Seasonic Silence Pro 750W at RM329 and the XFX XXX Edition 650W at RM369 ( getting hard to find as it's pretty popular ). The Gigabyte Odin GT 550W is priced at RM339 from PC-Zone.

If it is really that cheap, then yes, I'd recommend it.

It will support those system without any problems if there isn't any external graphics card. If there is, then it will depend on what card you're intending to use with the system.

On par with it? . What sort of power supply is on par with a chassis? .

If you're planning to change to a HD5670 later on, the Seasonic 520W Bronze power supply will handle it fine. It can even handle three HD5670s without any problems.

It's not necessary.

You can go with the Gigabyte Odin GT 550W at RM169 from Jayacom if you want. It's a pretty high-end power supply but it's rather old.

I'd suggest that you go with either one of those two power supplies as they have a very good performance to value ratio .

The Silverstone Strider 560W power supply should handle it fine .

I believe the Silverstone Strider Essential series power supplies are power supplies which are meant for people who do not have a lot of money for a power supply. If I'm not mistaken, it's much more basic than the Strider Series, but still pretty good.

It's not recommended; The Cooler Master eXtreme Power Plus 500W power supply can only supply around 430W of total power, and only 360W of power on its 12V rails, which is the rail that you should be giving extra attention to nowadays.

You will want to get a better quality power supply, e.g the FSP Hexa 500W, Gigabyte Odin GT 550W or the Silverstone Essential 500W at RM159, RM169 and RM199 respectively to power up those cards. A power supply with a terrible quality is never recommended because it could damage your hardware in the long run.

The Cooler Master eXtreme Power Plus 500W is able to supply power of up to over 400W, but that comes at a price; You will be having a high electrical noise and ripple on the rails, which will damage the hardware in the long run.

The power supplies suggested in post #3716 has at least 400W of power on their 12V rails, so it should power up those two cards fine.

It has more than enough power, but you will still want to get another power supply.

The eXtreme Power Plus and the GX series of power supplies from Cooler Master should be avoided as they have electrical noise and ripple issues on their rails. Again, it's not safe to have a power supply with electrical noise and ripple issues as it could damage your hardware in the long run.

But anyway, if you do insist on using the Cooler Master GX 750W, it should still be safe as the ripple and electrical noise issue is present at a certain load only, which is around 550W and above if I'm not mistaken. Most likely you will be using around 400W of power only anyway .

The Seasonic X-660 offers longer cables over the X-650 and also an extra 10W of power. . If the X-660 is only being sold for RM440, then perhaps you will want to go for that.

The first and the third power supply seems promising, unfortunately the second isn't so seeing that it's only 80 Plus Bronze certified. If its price is right however ( below RM500 for the 750W version and RM600+- for the 850W version ), then I guess it can be considered. Otherwise we'll just suggest people to get the Seasonic X-750 / X-850 seeing that these are only priced at RM599 and RM699 respectively, have a Gold efficiency certification, and that they can supply up to 748W and 840W of power respectively on their 12V rails compared to the Enermax's 750W's 648W on its 12V rails and the Enermax's 850W's 750W on its 12V rails.

The Enermax MODU87+ 700W CrossfireX power supply does seem to be a very nice power supply .

As for the 750W and 850W units, if it is really going to be priced at only RM350 / RM400 or below respectively, then I'd say it's a definite steal and you should definitely bring it in.

You could have a look at this article on the rails .

Link.

Otherwise if it's too long for you to read, then what the whole article meant was that single rail or multiple rails does not matter in a power supply, what matters would be the quality of the components they're using .

Well, no. Apparently it's what you call a placebo effect.

A placebo effect means that something in particular causes that person to think one thing is better than another, e.g an LED LCD monitor is better than an LCD monitor with a CCFL just because it's using an LED back lighting which is said to have much more vibrant colors over normal CCFL equipped monitors .

Anyway, for this case where people claim that single rail power supplies enable them to overclock much better, it's probably because their previous power supply was of a poor quality multi-rail power supply, and coincidentally they bought a single rail power supply that has a good quality.

The difference in efficiency between the Silver efficiency certificate and the Bronze efficiency certificate is negligible. Unless you're willing to spend an extra amount of money on a Silver efficiency certified power supply over a Bronze efficiency rated power supply to save some extra cash on your electrical bills, then stick to the cheaper one, unless the ones which are 80 Plus Silver are also considerably cheap or the price difference isn't too big .

The certification is to indicate how efficient the power supply can handle the power it draws from the power socket where it's plugged to. The higher its efficiency, the less electricity that it draws is wasted as heat and more is converted to power that can be used by the computer. For example, a 75% efficiency power supply that generates 300W of internal power would draw roughly 400W of power from the wall. Is it definitely not a placebo effect and the better the certification e.g Silver over Bronze, Gold over Silver and Platinum over Gold, the less power is wasted, the less heat is generated, and yes, the more silent the power supply would be as there's less heat; the fan is not required to spin at higher speeds to dissipate the heat.

Well, having a power supply that can supply an amount of wattage which is more than what you require is a good idea rather than having one that supplies just enough for the entire system.

Do note that power supplies degrades over time, and as they degrade, their ability to supply their rated power decreases .

If you can afford the 600W power supply with the gold certification, why not?
