More than enough. He could even run two HD4670 on the 400W power supply, provided that the board supports CrossfireX.

It's currently retailing for RM369 from Viewnet.

It will support .

No.

A hard disk only consumes around 3W ~ 10W+- at most. Adding one extra hard disk doesn't mean you need to get a better power supply. Many people make the mistake of getting a high capacity power supply just because they have e.g 3 ~ 5 hard disks.

No. It will use only what it needs, for example, 550W. And the thing is, you might even save a little more money on your electric bill as a power supply usually has a higher efficiency when it's half loaded.

Yes, it will be able to.

You can determine whether a power supply is a true power power supply or not by checking its 12V rail.

An example of a non-true power power supply :



This is the label of the Cooler Master eXtreme Power Plus 500W power supply.

Notice that the 12V rail's combined Ampere is 36A, but the output wattage is only 360W. If you try calculating its total wattage by using the formula ( 12V x 18A )², you're supposed to get 432W. However, the label states that it outputs only 360W.

To find out true ( A ) that this power supply has on its 12V rails, you can do so by taking 360W and dividing it by 12V, and you'll get yourself 30A, which is the true (A) that the power supply can output. 36A would be its peak wattage then.

An example of a true power power supply :



This is the label of the Cooler Master Silent Pro M 600W power supply.

It has a single 12V rail, and that the 12V rail can output a total of 40A. Now to find out if it's true, you perform the same calculation above, by taking 480W and dividing it by 12V. It gets you 40A .

For the "Gold, Silver and Bronze thing", it's there to indicate how efficient the power supply is. The best rating would be Platinum, next would be gold, then Silver then Bronze. The higher it is, the more efficient the power supply is.

Go with the Seasonic Silence Pro 500W at RM199 from C-Zone .

The Seasonic Silence Pro 500W is better than those two units you have stated.

That works too.

I believe the Cooler Master Real Power Pro can no longer be found in shops. .

Yes, it will.

The Gigabyte PoweRock 390W's label.

I would suggest that you get another power supply as the Cooler Master GX Series power supplies have high ripple and noise issues. Go with the Seasonic Silence Pro 500W at RM199 or the Silverstone Strider 500W at RM199 instead.

The answer is already in the post #3614.

For your system, since you have overclocked the processor, I'd say a 550W power supply would be sufficient for it. 700W is more than enough.

For RM200, you can get the Seasonic Silence Pro 500W or the Silverstone Strider 500W at RM199. What card are you planning to get in the future and what would your budget be for the future card?

Well.. The only few cards that you can get at that range ( RM500 ~ RM600 ) would be the XFX HD5850 RM499, Leadtek GTX460 1GB OC RM549, Sapphire HD6850 at RM579. These three will run under a 500W power supply fine.

Otherwise, if you're talking about one year later or something, then we'll see what we have then .

Hard disk drive normally only take around 5W ~ 10W of power.

But if you'd like to stay on the safe side, then go with the Silverstone Strider Plus 600W at RM279.

Avoid the Cooler Master GX Series power supplies as these power supplies are terrible in quality and will damage your hardware in the long run due to the high ripple and electrical noise on its rails.

It's old. But it was a highly recommended power supply back then.

Yes, it is enough. But if you haven't bought that power supply yet, I'd recommend buying the Seasonic Silence Pro 750W from Lingloong at RM329 excluding postage costs.
