I'm gonna try and contact someone in the Netherlands, he might be able to provide us with P&C products... Might even consider a grouped order if people are interested.

Will contact the guy tomorrow.

Hi all,
Sorry about the late reply. Thankyou for the clarification on Current vs voltage insofar as "storage" and the role of capacitors. Current does, however; flow through a capacitor as is explained in this most simple analogy. Technically Capacitors store Farads and have seevral uses, besides storage they are also used as "iinsulators". In the PCPower article where I was discussing the "pre-FET stage" of capacitance, these large caps are used primarily as a filtration method for reducing oscilation not for storage in the traditional sense. For example the DC cap's spec'd at the out stage are much "smaller" due to their rate of discharge and are used in a more traditional role as storage and to filter remaining AC. In the AC stage current isn't so much stored as it is conditioned via capacitors.

Modular Cabling is problematic do to resistence and a substantial loss which occurs at the plugs. The degradation on current has been compared to addiding two additional feet of cable. The junctions where the modular cables "plug-in" are susceptable to pins loosening, oxidation at the terminal, etc. This is what PCPower&Cooling says about Modular cables and why they do not use them;
Section 2.) Myths Explained at PCPower
DON'T LOSE POWER WITH MODULAR PLUGS
Due to their look, convenience, and cost savings for manufacturers, modular plugs have become a popular power supply feature. Unfortunately, there has been little or no discussion of the impact of this feature on overall performance and reliability. The fact is, modular plugs limit power by adding to electrical resistance. The voltage drop can be as much as would occur in 2 feet of standard wire. Worse yet, modular plugs utilize delicate pins that can easily loosen, corrode, and burn, creating the potential for a major system failure. That's why pros specify uninterrupted wire!

Regarding capacitors, its dangerous to make blanket statements about a geographic origin producing inferior products. Japanese Caps are and can be constructed as well as any other brand. The result of those inferior capacitors that sweeped the industry some time ago actually eranerd a name; Capacitor plague. I don't belaive one Japanses Cap maker supplied those.
Companies I consider to be the very best maker's of Capacitors (and resistors) would be;
1.)Vishay
2.) WIMA
3.) RubyCon
4.) Vicor
5.) Rel Multicap

Probably Rel, Rubycon, or Wima being the best. These are often used in Audiophile applications which says alot about the quality of these Caps.

Recently Tayeh Caps made in Taiwan were exhibiting a phenomenon called capacitor "buldge," which can eventually result in leakage;


Also Choyo caps had some problems;


The following List of Capacitors are known to have suffered from
Capacitor Plague
Tayeh (A brand that does not appear to exist, indicating the actual manufacturers were wary of putting their name on their product)
Chhsi
Teapo (Teapo has denied these claims, and evidence suggests their new capacitors are sound, however their older ones appear to suffer from the same problems other brands do)
I.Q.
Rulycon (A clone of "Rubycon", a well-known manufacturer of high-quality capacitors, right down to the exact style of the cases and the fonts used for lettering)
JPCON
Jackcon (The only capacitor manufacturer to own up to their mistake; they are also the only one to issue free replacement capacitors to people who had theirs fail. Their new products appear to be of greater quality.)
JDEC
CTC
(G) Luxon (also G-Luxon)
Gloria
Raycon
Hermei
Choyo
GSC
Nrsy
There's a site devoted to this topic
http://www.badcaps.net/
with complete lists, however; what's important to remember is most of these caps which usually copy names such as "Rulycon" trying to copy or sound like Rubycon, will never make it to quality mobo makers stocks. And if there were one company I certainly wouldn't ever worry about it be PCPower&Cooling.

The Capacitor below is one of approximately 5 found in (of this spefic type the PSU has many more) the PCPower&Cooling TurboCool 850 SSI

Well Liquid3D pleasure, you give a whole new meaning to the world "thorough".

Even used as Capacitor filter; it does not store current.

Current storage is normally called battery.
