高手个PP……闲着没事乱看文档而已……
就电源本身来说，当然是12V组数越少越好，配置更灵活方便。
就我自己听说过的，4路12V电源起码有两三种配置：1、主板×1+CPU×1+显卡×1+外设×1；2、主板×1+CPU×2+显 ...

兄弟 你说的zippy电源确实NB，我找到了一款1485W的单路12V电源 M1Z4-5E85V3H   
+5V 64A +12V 120A +3.3V 64A  这个规格太顶级了 估计要卖到5000rmb以上了吧~~~只能YY了啊

The top PCB has its own interesting features which mostly center on its use as the location for the primary capacitors as well as the PFC rectifiers. The large heatsink in the center of the PCB houses the six Infineon PFC rectifiers while below these are the two Hitachi 390uF 105*C industrial-grade primary capacitors and two more large chokes.

The secondary PCB also holds a 6x32 high-speed fuse on the input side in order to protect your other components if something would go awry with the AC input. Looking a bit further, we can also see some additional Nippon Chemi-Con caps and a smaller transformer here as well.

The power relay Silverstone used is a Fujitsu FTR-K2 series unit which boasts extremely low impedance which means higher efficiency for this power supply. The specification sheet for this unit can be found here: http://www.fcai.fujitsu.com/pdf/ftr-K2.pdf

Finally we come to the actual OEM for the ZM1200. Once again Silverstone has seen fit to use Impervio Electronics as they have been doing for most of their recent high-end designs. A few months ago Impervio was a relatively unknown OEM in the power supply business but they have been making some huge inroads with their completely automated manufacturing process. They are based in Taiwan and now (finally) have a website where PSU aficionados can check out their wares: :::IMPERVIO Electronics Co.Ltd:::

The backside of this top PCB is a lesson in precision soldering. There is not one point where there is any excessive flash or other leavings normally associated with a botched soldering job and overall, it shows some amazing attention to quality.

Finally, we have the amazingly hard to reach rail switch. It looks to us like under normal circumstances (ie: getting to it without voiding your warranty) you will need a pin of another suitably miniscule tool to switch it. Just remember: ON means there are multiple +12V rails while there is a single rail when the tiny rocker arm is moved into the lower position. Please don’t go jabbing around in here without assessing the situation since you don’t want to hit anything important like a resistor on the PCB.

如果以12V输出越少越好标准来判断，说明海盗船1000W还是很厚道的了，因为ANTEC 1000w和TT1500W电源是4组12V输出，而思民达到了6组12V输出

Corsair really pulled out all the stops when it came to the HX1000W since everything is done to near-perfection and that even includes something as small as a Molex connector. All of the Molex connectors have the very handy quick-release tabs installed which makes them a breeze to remove from components.

We have finally come to the brains of this operation: the modular interface. In our option, this is one area which either makes or breaks many power supplies since some companies have gone completely the wrong direction with their interfaces. That being said, like so many other things about the HX1000W, Corsair got this right.

To begin with they have included an easy to understand diagram detailing the locations of each cable along with the +12V rail it is associated with. In addition, they make the process of installing the connectors downright easy since a Molex or SATA cable won’t be able to fit into the connectors designated for the CPU and PCI-E cables and vice versa. To make matters even simpler, Corsair has color-coded one set of modular connectors blue while the other set stays black. Once you have chosen which cables you will use, it is just a simple matter of aligning the connector with the modular interface and pushing it in until you feel it click into place.

When we said it looked like the HX1000W is actually two power supplies in one, we weren’t kidding but looking a bit closer we see it is actually THREE separate power supplies. In the pictures above you can see two distinct layouts on the one PCB, each with its own transformer and single primary cap. It is an extremely impressive design where one “power supply” is a combination of +12V2 and +5V (via a small daughter board) outputs while the other one seems to handle the +12V2 and +3.3V rails. Meanwhile, there is a small inverted PCB whi**olds a small +5vsb power supply complete with a transformer and caps.

The heatsinks are designed perfectly for a downwards-pointing fan and look to be well placed to dissipate as mu**eat as possible. The only potential issue that we see with this design is the fact that the interior is so cramped; the components not in direct contact with the heatsink may not be sufficiently cooled. However, as you will see Corsair chose premium parts for this power supply so the risk of overheating is slim to none.

On one side of the power supply holds a pair of small vertical PCBs of which one (closest to the camera above) is used for the fan speed controller and a few other outputs we couldn’t identify but look to be PCF controls. Meanwhile, while we can’t see most of the rectifiers and diode packs, the ones we are able to take a look at were all well attached to the heatsinks in order to dissipate the considerable heat they generate.

The capacitor situation with this power supply is very interesting since while the primary filtering stage uses a pair of high-quality 105°C Nippon Chemicon caps, the entire secondary side is populated by solid caps. These solid caps are Nichicon LG-series conductive aluminum electrolytic units which should last much longer than standard electrolyte capacitors and this is the first power supply we have seen with the entire secondary side populated with such an abundance of these.

The modular interface is built quite well with the two +12V rails getting their own separate solder points while the +3.3V and +5V rails are also partitioned off into separate points which are clearly marked. The soldering seems very good overall so we can be assured of a clean transfer of power to the connectors.

We already mentioned that there is a separate +5VSB power supply and it is lurking near the back of the HX1000W and in the picture above it can be seen in all its glory. The small transformer is the green-wrapped object in the center while its main capacitor is a Nippon Chemicon unit.

放弃Antec TP4 1000W电源，原因有以下几点：
1.传说有高频噪音
2.居然用了4组12V输出，跟那些2组甚至单组12V输出没法比
3.电压输出波动太厉害，远高于海盗船和SliverStone
4.一张内部照片让我看到了山寨的影子

证据如下：
2.关于4组12V输出

3.关于输出波动对比
Output Quality Testing
下面是跟SliverStone对比，差太多了
+12V Ripple Testing

While not perfect, the ripple exhibited by the Quattro was well within the norms through all of the tests…even the Extreme Load test. There was a jump up to a bit over 50mV-pp to go hand in hand with the voltage drop in the Extreme Load test but this was to be expected and once again this power supply stayed well within ATX specifications.



下面是跟海盗船和TT的输出波动对比，远高于tt和海盗船
+3.3V Ripple Testing

+5V Ripple Testing

+12V Ripple Testing

First of all let us say that we were once again floored by how well the Corsair HX1000W performed from one end of our test suite to the other and this was borne out once again in our output quality tests. While all of the results were more than acceptable, we were most impressed by the +12V ripple tests where even with it outputting copious amounts of power, the HX1000W kept the traces below 35mV. All of these tests go to prove that Corsair has an extremely well-built power supply on their hands.

A little mention should be made about the sudden decrease in ripple seen on the +3.3V rail chart during the GPU Load test. We believe this is happening because the game used does not put much load on the RAM (through lower CPU usage than in the CPU Load test)and thus not much load on the +3.3V rail either.

4.内部做工山寨的证据

Silverstone也有6组12v输出的产品，这个电源貌似也很yy，售价400CAD加拿大元（1加拿大元=6.7人民币，跟美元差不多），优点是所有接线模块化

One thing becomes painfully obvious once the Zeus 1200W is unpackaged: this is a massive power supply. Even with the fully modular connectors uninstalled, it still runs 21.5cm (8.5”) in length which could be a problem for some cases. On the other hand one would assume that if you have $400 to spend on a power supply you would have spent the money for a suitably massive case as well.

Overall, the design of this power supply can only be called sleek since there are no overly large 120mm or 140mm top-mounted fans breaking its smooth lines. Closer to the modular interface there are small perforations in order to facilitate airflow into the housing to cool the components. On many power supplies with a single 80mm exhaust fan, we see these perforated grilles on the same side as the connectors. However, since the modular interface takes up an entire inwards-facing side of the Zeus, Silverstone had to move these air inlets somewhere else.

The other end of the Zeus holds the 80mm ball bearing exhaust fan as well as the usual power switch, mounting points and AC power input. The matte black finish seems to be quite resistant to scratches and it really does give this power supply a stealthy feel…even though it is humongous.

SilverStone DA1200 (1200W), 全模組化线材,单组+12V輸出90A
2400元 http://auction1.taobao.com/auction/item_detail-0db1-c5d9c830bd6b040ce0dcad9cd7906af6.jhtml
中意它的主要有4点
1.单组12V输出达90A
2. 5v和3.3v达到了40A 40A
3.全模块化，连主板供电都是模块化
4.2400元价格还不算很离谱，跟Zalman 1000W差不多，比TT 1500W还便宜
