Channel Well Technology >> PC Power Supply >> ATX12V DSA Series (80Plus/Bronze) >> DSA 500 (80PLUS/80PLUS BRONZE)

Mao ni akong gigamit karon sa akong specs:

AMD Phenom II X4 - 945
ATI 4870 1G
4G DDR2 800
Seagate 500g 720rpm
Gigabyte Mobo
Dvdwriter

Ok ra ni nga model?

What do you think of this model?

Thanks,
King

Channel Well is one of the OEM of Corsair PSU, the other one is Seasonic. Some models of Thermaltake & OCZ PSU's are also made by CWT...

Do know though that although they are an OEM maker, it does not mean you get the same quality, because all those Branded ones they make have different technologies implemented on their PSU's and almost all the time, patented technologies. So meaning if they manufacture corsair, then kana nga particular model will only be made for Corsair.

Not necessarily. Read this:

We can separate power supply companies into three groups: the ones that design and manufacture their own products (the minority), the ones that design their own products but hire another company to manufacture the products for them, and the ones that use OEM products, i.e. another company designs and manufactures their products, but adding the label, box and manual from the contracting company. Almost all well-known manufacturers that aren’t originally from the power supply business fall in this last category.

Is this bad? Maybe. As the quality of the power supply will not depend on the labeled brand but on the real manufacturer, a given brand can provide a terrific product line on their original business (memory, cooling or whatever) but a different quality level for their power supply line. But we strongly believe that manufacturers will choose other manufacturers with the same quality level or they would get burned pretty quickly.
We can also have the funny situation of two different brands providing exactly the same power supply, as many original manufacturers are providing products to more than one brand. In some situations you can also find the same power supply on the market under the real manufacturer brand.

Yes that is true, but most of the big companies that are in the top tier will most likely have their own patent/trademarked design. It is very simple to find out, open the PSU and take a look at the board.

Trust me,the ones that just put a name on a shared design isn't a serious PSU maker. These are companies on lower tiers, I will not mention names as to not hit any company in particular.

[greywolf]

this may be correct in some cases but not all. There can also be a situation of two different brands providing exactly the same item/product, as many original manufacturers are providing products to more than one brand. In some situations you can also find the same product on the market under the real manufacturer brand.

Here's an example: SilverStone Element ST75EF is a relabeled Seventeam ST-750P-AF.

Phase III compensates for overcrowded Tier 1, while clumping together previously Tier 2 and 3 PSUs if only because no definite way to categorize then as good enough for Tier 2 or bad enough for Tier 3.
