硬盘上有标的,不同硬盘有些差别，不过一块硬盘的5v最大功率就1A

作者: bcyj 时间: 2008-7-13 17:59
要专业的话，上1+1或者2+1吧

7个3.5 15K也不过100W不到，只要4Pin输出是单路12V，10A以上，或者连CPU 4pin/8pin输出，单路21A以上就OK了……
能上RAID6滴RAID卡，肯定支持延时Spin Up的，不需要太担心Spin Up电流不够的问题。

当然最稳妥滴是650W以上，单路12V 35A以上滴……

不过说回来，LZ用的什么卡？能支持RAID6？另外如果考虑写入性能的话，其实8块硬盘做RAID 0+1比RAID6要好得多，RAID 5写入就够慢了，RAID6 比RAID5还慢……

作者: harleylg 时间: 2008-7-14 02:29
仔细搜索了下文档，按照ST滴15K6 400G SAS来算，启动电流是12V 4.56A，5V 1.95V也就是同时启动需要12V:4.56*7=31.92A，5V:1.95*7=13.65A，就算再加4个同样滴硬盘是12V:4.56*11=50.16A，5V:1.95*11=21.45A。不过RAID卡一般可以设置分组启动，如果设置为2个一组的话按照12V 4.56×6/5V 1.95×6计算，如果设置为4个一组的话按照12V 4.56×6/5V 1.95×8计算……

高手啊~~让我先来膜拜一下！！！！Orz
我问一下，TT有4组12v输出，Zalman有6组12V输出，请问这个12v输出的组数是越多越好还是越少越好啊！！
每块硬盘都有12v和5v，问题是12v输出有4~6组而5V只有1组，我接硬盘应该怎么接啊~~通常模块化电源每条线最多接3个SATA或4个大4Pin，我如果用转接头实现一条线接更多硬盘是不是不成啊？？？
按照大师的算法也就是说1000W电源里面5V输出最差的Antec 1000w的30A也可以满足需求喽？最重要的是Antec 1000w最便宜1500元搞定了，如果买5V达到40a的Zalman 1000w要花2200元大洋呢
至于TT 1500w我有点担心，这个品牌就喜欢什么都把参数弄得吓人，反观台达，海运等NB品牌的电源700-800w已经封顶了，你说tt为啥动辄就上1500w，这参数来的实在嘛？

问题是单个电源的5V输出安培数不够啊~~~
你想想10来个硬盘同时启动对于5v线路造成的压力还是不小的。如果是双电源肯定是一批硬盘接650w上面，一批硬盘接550w上面

大家谁用过Zalman的1000w电源啊~~这牌子做工扎实不？？？卖得比Antec贵很多，是不是用料也比Antec强呢？
Antec特长是静音，但是听说过热
Zalman特长是静音+散热！！！就是不知道这牌子在电源领域有啥建树

我的NMB460，接6快硬盘，3个1W转的3个普通的外加4个光驱，不过我的显卡比较省电{shy:]

启动运行没问题，风扇加起来有10个，启动电流也有1-2A了哈哈

所以10硬盘不是很可怕的

每块硬盘都有12v和5v，问题是12v输出有4~6组而5V只有1组，我接硬盘 ...

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+显卡/外设×1；3、主板×1+CPU×1+显卡×1+显卡/外设×1，不同电源侧重点不同，而且我只见过银欣的电源提供分路说明（事先说明，我用过的电源很少）。

理论上Antec P190附带的双电源应该OK的，650W滴主电源只负责主板+CPU+显卡，550W滴副电源只负责外设，虽然5V输出只有20A，不过那个一来只是额定电流，根据上面的计算，启动瞬间的22A不到的要求肯定是没有问题的，二来15K6 400G SAS是我查过的硬盘中电源要求最高的，就算是15K6 200G的要求都低不少，就算你的7个SAS都是15K6 400G，四个SATA硬盘肯定要比15K6要求低，三来就是上面提过的RAID卡的硬盘分组启动，所以不会真的需要22A的5V输出。

别的牌子不太清楚，不过SST的OP850/DA850应该比较靠谱一点，都是单路12V 70A输出，基本够用了。当然更高的OP1000/OP1200/DA1000/DA1200更加没有问题。Zippy滴单路电源似乎有点太贵了，不过的确YY……

标题: Silverstone Zeus 1200W

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.

标题: 海盗船1000W 只有2路12V 算是不错的了
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.

标题: 放弃Antec TP4 1000W电源
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

标题: Silverstone Zeus 1200W
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.

入手啦上图包装比较旧估计放了一年也没有卖出去难得碰上我这么一个大头至于噪音我也很在乎，但是我想等我把10几块硬盘装上，噪音已经不需要控制了

赞成这句话

首先恭喜楼主，介绍一下使用情况吧。

最近也比较关心电源，查了一下，银欣有好几款1200W的电源：

SilverStone DA1200 (1200W), 全模組化线材,单组+12V輸出90A
SilverStone ST1200 (1200W), 全模组化线材,6組+ ...

SilverStone DA1200 (1200W), 全模組化线材,单组+12V輸出90A 23CM长真的很长，比我的还长
SilverStone ST1200 (1200W), 全模组化线材,6組+12V輸出94A 长度比较短，适合更多的机箱
Silverstone ZM1200M 1200W全模組化线材,6组+12V輸出94A 23CM长
Silverstone Zeus 1200W 6组+12V輸出94A 其他不清楚
SilverStone OP1200 （1200W）非模块化单组+12V輸出90A

反正顶级是DA1200，但是停产了。现在主打ZM1200M 是6组12V输出

多硬盘系统考验的只是5v和12v上比较大的启动电流而已。“玩家”电源能带高端显卡，12v电流肯定不会小，但5v多大就看厂家怎么定规格了。3.3v基本上不用考虑，sas什么的我不知道，sata似乎3.3v目前还用不到。

你说到了问题关键，现在很多RAID卡的数据线是包含供电的，如此说来硬盘供电都从主板过来。但是电源12V如果被分成6组或4组，恰好分给主板的那一组电流用的差不多了，现在又要分给8块15000rpm硬盘供电，启动的瞬间难免有问题。所以12V还是单组供电或双组供电较好，那些分成4组或6组12V的电源其实是实力不济的表现。因为单组12V做到90A输出难度大，而多组并联好控制的多。

这个原理跟硬盘分区一样。以前我喜欢一块硬盘分5~6个区系统一个区，临时文件一个区，文档一个区，音乐一个区，电影游戏一个区，软件和Ghost一个区。
后来发现分区越多，空间浪费越大，每个区剩余空间到2G左右几乎就不能装啥了，如果突然有个4~6G的游戏过来，真不知道放在哪里。后来开始用PQ合并分区，一下子剩余空间变成了10G
电源也是如此。12V分6组，正常应用每组都满足需求，如果一下子应用变了，突然有个耗电大户进来，发现哪一组12V都无法满足。所以王道还是单组12V输出，如果显卡用电不大可以分给硬盘。硬盘只有一块的话剩下的电流给CPU。好像PCPOP网站对ThermalTake 1500W电源评测编辑时，编辑的一句：“12V分4组的并联是个很“聪明”的做法”的评语就能看出12V分多组并联实现更大功率输出是一种廉价且聪明的做法，光是1500w这个数字就树立了高端形象，而实现起来难度又不高，很多消费者就冲着这个啜头去买了。而我一直很喜欢的Zalman 1200w居然用了6组12V。也不能说多组12V就不好，关键看自己的应用吧！！！SilverStone也有6组12v的产品

随便一个电源就行了

我的电源是航嘉冷静王维斯塔，，，，，，高清交流的时候，，插了一堆硬盘

两块15000转的SCSI，6块640G的西部数据，一共8块硬盘，没有任何问题

我现在也有一点觉得1200w有些浪费，关键是噪音太大。估计Antec会好很多。
俺决定要上15块10000rpm 的300G硬盘做raid 弄个4T左右容量出来放HDTV，相中了DELL MD3000盘阵，以后我那书房就不是人呆的地方了，噪音致癌！！！

sata2/AHCI也支持顺序启动的。

不过lz表达不准确，没有什么显卡功率，硬盘功率之分，多硬盘系统考验的只是5v和12v上比较大的启动电流而已。“玩家”电源能带高端显卡，12v电流肯定不会小，但5v多大就看厂家怎 ...

我木有看到过有主板支持SATA硬盘分组启动……当然，SATA硬盘也是可以接在SAS RAID卡上面的，这样可以分组启动。不过常见的中端SAS卡都是4/8口，LZ本来就要上7个SAS了，第一组SAS应该是和接在主板上面的4个SATA硬盘同时启动的。

这个算式不对哦，既然分组启动了，算最大峰值的时候启动好的盘只要按正常工作电流算就可以了。

我是按照2个/4个SAS硬盘和4个SATA硬盘同时启动计算的……

刚发现你是钱多了没处使……
HDTV这种东西对硬盘速度根本没有要求，不管是下载/自己压片/朋友间交流/播放，性能瓶颈都不在硬盘性能……
想要4T容量，4个1T容量的西数GP系列最合适，而且没有必要做RAID，这种不会经常访问的东西，硬盘不容易坏，就算坏了，这种娱乐东东丢了就丢了，大不了花点钱找人重新拷贝一份回来……

竟然为了HDTV考虑用15块硬盘建RAID6……不知你怎么想的……

作者: harleylg 时间: 2008-7-21 01:08
补充一下，个人对HDTV存放的理解是大容量硬盘下载，机箱支持SATA/SAS热插拔/或者自己买个光驱位的热插拔架就好……下满了换个新硬盘上去。
然后自己做份列表贴在硬盘上，想看什么片子接上去就好。

我在公司lenovo品牌机bios'里面看到了延时启动有3秒 6秒选择但是机器只有1块硬盘不知道是否所有硬盘都会按照这个设定的时间一起延时，

虽然对噪音不是要求不是很高，但还是犹豫了

DA1200不是大风车的么？噪音难道还非常的大？那ZM1200不是和飞机一样了阿~
