. It looks like the price has increased for that power supply.

Anyway, you can get it for RM219 from Viewnet.

It's just slightly better, but if you want it to be the best then that's one of the options you can turn to.

And electrical bill wise, it should lower your electrical bill since a power supply with a higher efficiency wastes less power compared to one with a lower efficiency. Bear in mind that although you have a 1000W power supply, if 500W is all your system requires that that is what it will use. The power supply does not supply 1000W all of the time unless you are using that amount.

It actually depends on the users.

If you want a power supply that is silent, and that can help you save a bit of money on your monthly electrical bill, then you should definitely go for power supplies which have a high efficiency e.g those with a Gold certification. There is also a Platinum Efficiency certification but those aren't very common, and will cost you a lot of money.

Otherwise if you're fine with noise and just want a power supply to supply the required amount of power for the system, then getting a power supply with an 80 Plus or 80 Plus Bronze ( 80% efficiency and 80~83% efficiency respectively ) will do fine. An example would be the Seasonic Silence Pro 750W power supply. The higher the efficiency of a power supply, the less power is wasted, that causes less heat to be generated, which ultimately negates the need for the power supply fan to spin at high speeds to cool the power supply down.

I'm currently using the FSP Aurum Gold 700W which is a Gold certified power supply, and it is a very silent power supply and it also runs cool .

Seasonic is one of the best power supply manufacturer in the industry. Their power supplies are widely used and re-badged by other brands e.g Corsair and PC Power & Cooling to be sold as their own.

Gigabyte's also fine but their power supply list hasn't been updated for quite some time, and most of the shops are still holding old stocks, so you're better off going with other brands e.g Seasonic. As for AcBEL, their lower-end power supplies isn't exactly commendable while their high-end power supplies are pretty good, albeit not the best.

From the power supply list that you have gotten, your priority would be to get either a Seasonic 500W / Corsair 500W or a Silverstone 500W power supply, while the other two PSUs should be left as an alternative option. As for your question on the cooling fan, a 120MM fan is definitely better than an 80MM fan as the former does not have to spin as fast as the latter to generate the same amount of air, therefore reducing noise . But if the smaller fan has a good design then it's also possible that it will be better than a 120MM fan of poor quality.

The weight of a power supply used to be used by people to determine the power supply's quality, but now it's no longer accurate as technology has advanced to a point where power supplies can now provide more power with components that weigh less.

As for cable sleeving, it actually depends on the individual. While it may be an eyesore for some, lets face it; you get what you pay for. RM159 for a 500W power supply is pretty cheap. If you demand the rest of the Hexa cables to be sleeved, then be prepared to pay extra. Even without its cable sleeved, an individual's cable management for his or her system still can be very good provided that the chassis itself has the appropriate cable management holes.

Anyway, I believe the Hexa power supply is not only one that suffers from a 4+4 CPU power connector that's too short, my previous Cooler Master eXtreme Power Plus 500W and even the Cooler Master Real Power Pro 650W power supply have a CPU power connector that's too short to be routed through the back of the motherboard tray and out from the top. These three power supplies are probably not the only power supplies that suffer from such an issue.

In my opinion, I'd say that FSP made it ( HEXA ) in such a way because they had low-budget users in mind, as in users that do not own chassis that is designed according to our decade's standard, e.g chassis that still has its power supply location located at the top instead of the bottom.

You can consider the FSP Aurum Gold 700W for RM489 from ALL IT . It will support two HD5870s and also the rest of your items fine.

That depends on your entire setup, but a 600W power supply e.g the Corsair GS 600 can support 2x GTX560 Ti fine in a high-end system as its 12V rail's very beefy .

To be on the safe side, you should get a 650W power supply or perhaps a 700W power supply.

If you are looking for a power supply that has a good price to performance value, then your best bet would be the Seasonic Silence Pro 750W power supply. If you could afford the Seasonic X-750 then you should go for it. There's the Seasonic X-760 so you should take that over the Seasonic X-750 if you can. It has longer cables if I remember correctly.

If you intend on saving some extra money on your monthly electrical bill, then you should buy power supplies which have a high efficiency rating e.g one with a Gold efficiency certification. Power supplies that have a high efficiency also tend to run cooler as well as much more silent than one which is less efficient as there will be less heat produced because less electricity is wasted.

If you want your system to run silently then getting a power supply with a high efficiency is one of the ways you can use to reduce its noise as the fan will not have to spin at speeds which can generate quite a bit of sound to remove the heat produced by the power supply.

Well then, the Corsair GS 600 will still hold. Guru3D's test of two GTX560 Ti in SLI mode had the power consumption going at 449W ( whole system ), and the system has an overclocked Intel i7 965.

Since your system is using an Intel Core i3 530 ( if I remember correctly ) processor, then the power consumption will definitely be less than that. The GS 600 can supply up to 576W of power on its 12V rail and that's still more than enough for your system even when it's overclocked. However, again, to be on the safe side you should consider going for a 650W / 700W power supply

There doesn't seem to be any review on the Strider Essential 700W, but considering that Silverstone is pretty well known for power supplies which are good / excellent in quality, I don't see any reason to not get it other than price factor.

If it's a good 600W power supply then it should support two GTX560s.

It works, but it's not recommended since it will stress the power supply. Power supplies which are stressed may not last as long as the manufacturer has intended it to.

It will only supply the required amount of power, not 1000W at all times.

Actually the Gigabyte PoweRock 390W will power a HD5770 fine.

A system with an Intel Core i5 750 with a HD5770 in it consumes around 208W ( load ). The Gigabyte PoweRock 390W can supply up to 288W of power on its 12V rail, which is more than enough to run the system. Whats more is that benchmarks tend to stress the PC components to the max, which means that the average power consumption will be higher than usual. The average users does not run their system with their system components loaded to 100% all of the time.

But before we confirm that it will run a HD5770 and your system fine, what are your system's specifications?

What is his monitor's resolution?

Well then, a HD5750 will do fine at that resolution. It consumes less power than the HD5770 too so you won't have to worry so much about running it with a Gigabyte PoweRock 390W. But seeing that a HD5770 costs just around RM30 / RM50 more than the HD5750, perhaps you could suggest that your cousin get the Gigabyte PoweRock 390W first then get a better power supply in the near future, or cross your fingers and hope that the PoweRock 390W runs his system and the HD5770 fine for as long as he is intending to use it .

Then he can choose to go with either the HD5770 or the HD5750.

Yes, or you can choose one that has the best cooler ( that is if they're not all using AMD's HD5770 reference cooler ).

You're going to have to browse through the available HD5770s / HD5750 at Low Yat. The shops' price list does not give a detailed information of the HD5770s / HD5750s that they have.

It's able to .

There aren't any reviews on that particular power supply, unfortunately. However, on paper it looks pretty good for a 500W power supply. It can supply up to 432W of power on its 12V rails and its also 80 Plus certified.

It's enough to power up a single HD5830. However, for two HD5830s, you will need to get a power supply with at least 600W of power e.g the Corsair GS 600 power supply which has a beefy 12V rail to power up two of them to be on the safe side.

If you intend to buy the power supply from him then you're going to have to see if it's working fine by testing it with a system. Alternatively, you can always use a small metal wire to jump start the power supply and connect some fans to it to see if it's working ( if you're interested about the jump starting part you can request for more info ).

The Cooler Master Real Power Pro 550W has a "fault-LED" which is red in color and is located beside the power supply's switch. It lights up if the power supply is faulty, so the task of identifying a faulty power supply should be very easy with it present.

I would however, recommend that you get a brand new power supply as the power supply from that link is only covered by 40 days of warranty. A new power supply usually comes with 2 ~ 3 years of warranty or 5 if you're buying a premium power supply. You will also be able to avoid any worries e.g a power supply's premature failure since a new power supply is, well, brand new and it should not have any problems.

The Silverstone Strider Essential 500W is a pretty good power supply. You can go for that if you like. You can also choose to go with the FSP Hexa 500W power supply at RM159 which is a good power supply. Only its main 24-PIN motherboard and CPU connector ( if I remember correctly ) is sleeved though, so if a power supply's aesthetic is important for you, then feel free to go ahead with the previously mentioned power supply ( Silverstone ).

It's more than enough. It can even power up the system with the HD6770, though a 450W power supply is recommended for safety and power supply lifespan reasons.
