You can refer to your motherboard's manual for that.

Just for your information, to know which pin head goes to which pin, the ones with a small arrow on it indicates that that particular pin is positive. Try taking a look at the chassis's headers and you should see what I meant .

Which 850W model of Corsair are you talking about? But anyway, Corsair power supplies are good and yes, it will support two GTX580s .

Added on May 29, 2011, 7:38 pmIf I'm not mistaken, the UK is also using 230V like our country. There's nothing to worry about . The Silent Pro Gold 600W also has APFC, which automatically corrects the AC input voltage.

The minimum for the HD6850 would be 400W, while the recommended is 450W. .

It's not recommended to stick to the minimum recommendation. Get a power supply like the FSP Hexa 500W.

It can be gotten for RM169 from Jayacom. However, its availability might be very limited as it's a very sought after power supply due to it being modular, 80 Plus certified as well as being a very good power supply.

Although the Seasonic X-560 is an excellent power supply ( the X-series of Seasonic is very good according to reviews around the net ), it's priced at RM359, which is rather expensive. You have some other alternatives out there e.g the Silverstone Strider Essential 600W which is cheaper, albeit not as good as the Seasonic X-560 in quality. In addition to that, if your budget is at RM359, then you have the option of getting the Seasonic Silence Pro 750W for RM329 from the Garage Sales section. It ( 750W ) has the ability to output more power than the Seasonic X-560 and it costs cheaper, although it's less efficient and it's not modular. In other words, the Seasonic X-series power supplies are premium power supplies and you should only go for them if you really have the money to spend and you would like to get yourself the best of everything.

Not all modular power supplies are expensive, or perhaps your definition of expensive is different .

Anyway, yes, technically a power supply with the ability to output e.g 800W that runs a system consuming only around 400W, which is 50% of its capabilities should have a higher efficiency than a power supply with 450W of power running a 400W of power. Most of the power supplies runs has the best efficiency at half their load and reduced efficiency at higher or lower loads according to most of the power supply efficiency graph I have seen before, for example these two :

Well, actually a better choice than the available power supplies in that range would be the Gigabyte Odin GT 550W that costs RM169 from Jayacom. Unfortunately, its availability may be a problem, and if it's really unavailable, then you can choose to go with the Silverstone Strider Essential 600W for RM279 from Viewnet, or the Seasonic Silence Pro 750W for RM329 ( without postage cost ) if you're able to spend more than RM300.

The FSP Hexa 500W is better as it can supply more power on its 12V rail which is 402W ( if I remember correctly ) compared to the Gigabyte Superb 550W's 360W. In fact, the Gigabyte Superb 550W's true overall power is only 450W.

. Perhaps you should have the name of any items recommended here noted down in your phone using the "notes" feature or something to prevent getting scammed in the future. But if that's really what happened to you, who knows that it might have happened to other users as well.. . This doesn't seem to be very good.

It's a pretty good choice, but if I'm not mistaken its cables aren't sleeved, which might be important to certain users who have aesthetics of an item on their priority list as well.

Other than the graph posted above, which can be referred to but not for everything since every individual's system component varies, you can always refer to the reviews of any GPU that you're getting or you're using to see how much power they consume on load. Then with the load power of the card measured, you combine it with the rest of your system components ( estimation ) and find a suitable power supply. In this case, yes, the Cooler Master Silent Pro M600 will run your system without any problems. The reason on why people buy their power supplies according to the graphics card they're getting is because the GPU is the most power demanding component in a system ( generally ). Otherwise if you're running your system without a discrete graphics card, then you should be able to run it fine with a generic power supply, but that's not recommended.

If the rest of your system components is exactly like what your CPU-Z report states, then yes, the Cooler Master Silent Pro M600 will support the GTX570 or the GTX580 and your system without any problems.

Is the card an nVidia 7600GS or a 7600GT? Anyway, these two cards do not consume a lot of power, and your power supply should support the entire system without any problems. But according to your statement, it seems like two hard disk drive has already crashed for no apparent reason on this system. Have you tried getting another power supply to test your system with? You could buy the Gigabyte PoweRock 390W at RM69 ( All IT ) if you do not have any additional power supply to test your system, which will also run your system fine.

No no no no no. Even if you got a 500W or a 400W power supply, if 300W is all your system needs then that's what it will actually use. The power supply will supply power according how much the system requires and not e.g 400W all the time if the total power capacity of that particular power supply is 400W. A power supply's rating is stated on the power supply itself and the box to indicate the power that it can supply up to ( for good power supplies they can usually be stressed more than what the manufacturer says, albeit not recommended ), not indicating that it supplies that amount of power 24/7.

Anyway, you'll get more savings on your electrical bill on with a 500W power supply compared to a 400W power supply as power supplies usually have the best efficiency at around 45% ~ 65% of load, unless the 400W power supply is an 80 Plus certified unit ( meaning that its efficiency is guaranteed to be at least 80% up to its rated power e.g 400W ) and the 500W is not.

For the first build, you could consider the FSP Hexa 500W which costs RM159 from Low Yat Plaza. For the second build, a Gigabyte PoweRock 390W that costs RM85 will suffice.

Durability depends largely on your luck, but in terms of quality Seasonic and FSP produces power supplies that are good or excellent in quality. Unfortunately Cooler Master seems to have forgotten their trade secret in making good power supplies like they used to e.g the Real Power Pro power supply series and now they seem to be churning out power supplies with problems. Until they improve the quality of their power supplies, it's recommended that you avoid some of Cooler Master's product, especially the GX series, the Silent Pro Gold 1200W and the Silent Pro Gold 800W power supply, and the Cooler Master eXtreme Power Plus series ( expensive; not very good in quality ).

Your friend definitely does not know much seeing that he could have said such a thing. FSP is a good brand, and a good manufacturer. They make their own power supplies . You can always search up for any reviews for the FSP Aurum CM Gold 650W power supply. Most, if not all of their power supplies receives excellent / good ratings. Cooler Master on the other hand does not manufacturer most, if not all of their power supplies. The Cooler Master Silent Pro Gold 600W is also a good power supply though according to the reviews, but if the FSP Aurum CM Gold 650W is just slightly more expensive, or cheaper, then you should go with it as it has a higher overall power capacity, as well as the ability to supply slightly more power on its 12V rails ( 600W versus Silent Pro Gold 576W ). The 12V rail is the most utilized rail in every modern PC system nowadays so this is a very important rail.

For any reliability concerns, it actually depends a lot on your luck. Every individuals have a different experience with different power supplies. What they experience will not be what you will be experiencing. Of course, the brand matters up to a certain extent too but we're talking about Cooler Master & FSP at the moment, who both offers good power supplies ( some of Cooler Master power supplies are excluded from the statement ). Go with whichever power supplies you like as they are both good power supplies. Your priority would definitely be the FSP Aurum CM Gold 650W as it can output more power. But if it's priced a lot higher than the Silent Pro Gold 600W, then you'll know what you should be going for.

It will more likely cause random system hangs/freezes, or you might experience blue screen of deaths. As for the downclocking of a graphics card, it's normal in every new graphics card nowadays and it's meant to reduce power usage as well as heat when the graphics load does not require the card to be at its best to run properly.

The HD6850 should run fine with the Cooler Master eXtreme Power (Plus) 500W, although it's not recommended due to its quality problems. The power supply does supply enough power though on its 12V rails for your system so insufficient power shouldn't be the cause.

You can turn your extension upside down and see what is the max input current it can handle. Then with the information gathered, see how much (A) does the input current of your power supply and the rest of the items have. For example, at 230V my Aurum Gold 700 has an input current ampere (A) of 5A or below, and assuming that the extension can only handle a max load of 13A, you have 8A to support the rest of the devices.

You can consider the Silverstone Strider Essential 500W for RM199. An alternative would be the Corsair Gaming Series 600W power supply for RM299. Your system's power consumption is estimated to be around 250W or so, so with a 500W power supply you should have it running at close to its best efficiency since it's being half loaded. Most power supplies have the best efficiency at half load. You can go with the Corsair Gaming Series 600W power supply if you intend to use the system for a long time and plan to upgrade in the future.
