5 out of 5 eggsThey say 5 volts only on this cable

Pros: This review relates to my earlier review below. At that time I said that this must be the regular cable that I own two of, but I have since found out that Koutech does indeed sell two of these power over esata cables - the "5 volts only" is $5 cheaper than the 5 volts and 12 volts version. If you run 3.5" drives, you need the one that also supplies 12 volts.

Cons: This cable says no 12 volts, and assuming that is true - see top - then don't get it for a regular 3.5" desktop hard drive - it will only work for laptop 2.5" drives. (Maybe also for SSDs.)

Other Thoughts: I was not aware that they supplied two versions of their power over esata cable. Everything in my full review holds. The cable is very useful, but I would myself spend the extra $5 and get their cable that very clearly says 5 volts AND 12 volts. I am not aware of any 3.5" desktop hard drives that do not require 12 volts to drive the spindle motor - the motor which rotates the drive. The smaller laptop drives run off 5 volts and do not require 12 volts. All the caveats - all the cautions in my full review apply to this cable as well, since laptop drives also have micro-processor-driven controller boards, of course, which depend on a clean source of 5 volt energy.

5 out of 5 eggsRun a raw drive, no enclosure needed

Pros: You can take a raw hard drive, like I do, and plug it into this cable which protrudes over the front of my everyday desktop, and which connects in the back of my computer to a special esata two-port card installed in my pci-e 1x slot. Read about the card in "other thoughts" below. As soon as I do that, the hard drive comes into disk management.

These are either 2.5" drives, or mostly 3.5" drives, and they do get full 12 volt power and they get 5 volt power.

That is really nice not to have to crack open the case and run a sata signal cable out and run a separate sata power cable out.

Additionally I have an esata cable plugged into the other port of that two-port esata card. I use that esata cable strictly for signal, when I plug it into an A/C powered external hard drive.

I get esata speeds, much faster than usb 2.0, as fast as internal sata speeds, up to 100 MB/sec, versus practical 18 MB/sec of usb 2.0.

If you try to run two of these special cables at the same time, with the special pci-e 1x card mentioned below, but you have used ONLY floppy power to supply 5 volts to the card, you risk losing both hard drives, due to a design flaw in the special card that limits the 5 volt amperage to the esata ports, so the two hard drives running at the same time, will not be able to maintain steady controller board power, and you may ruin both drives, which is exactly what happened to me.

I still ended up buying two more cards later, because I now understand the limitations and how to use the card, and the cable.

If you read this, you will understand also.

I do presently have an everyday desktop, with the special power over esata card, and this special power over esata cable, and I have ONLY floppy power with 5 volts to the card.

Yes, I DO NOT have usb power - I could not find a usb header on the motherboard. So I have one special power over esata cable, and ONLY one.

I have no qualms running only one hard drive off this power over esata cable. I can only run one, because the other special cable is in storage.

Plugged into the second port of the special card mentioned below, is a normal esata cable coming out to the front of my case. That is for supplying esata signal, to a drive inside a regular A/C powered esata enclosure. So two cables come from the back out to the front of the case where I can reach them, an esata cable, and this special power over esata cable.

I have run many raw hard drives through this one special cable, testing, formatting, etc. with never any problem at all - works perfectly. But only one special cable on that desktop tower, because of FLOPPY 5 volts to the special pci-e 1x card.

On another computer, when I first encountered this cable and card, several years ago, I was able to connect the usb cable that came with the card, once I realized what it was for – there are no instructions, lol. (You are reading the instructions at this minute.) When I did connect the usb cable, then I saw that I was able to simultaneously power both of these special cables that I had purchased, with no problem.

However, further testing of those hard drives proved that they had already been damaged, before the usb cable was connected.

So: 1. usb power to the special card through the usb connector that comes with the card, great, you can run two hard drives simultaneously with two of these cables,
But 2. floppy 5 volt power to the internal card = run no more than one drive on this special cable

With usb power to the special power over esata card, you will have no problems. It is much easier to find floppy power and this is what you will probably do, in which case do not buy more than one of these special power over esata cables, the 5 volt power will be fine for ONE hard drive, but not for two at the same time.

For starters, you must use this cable with a card that carries the voltages for your hard drive. A 2.5 inch laptop drive uses only 5 volts. A 3.5 inch desktop drive uses 5 volts for the controller board, and 12 volts for the spindle motor. For the description to say that it supports 3.5 inch drives, but supplies only 5 volt power is ridiculous, and simply very bad tech writing. Without 12 volts the 3.5 inch drive won't rotate. I own two of these cables, and 3 of these cards. The cable mates to the following card, item number N82E16816104012. Newegg is out of stock but you can find the card on the net if they decide not to stock it. It is the koutech power over esata pci-e card. This is a high-tech item, so read this entire review.

When you read about the card, unlike this cable, the card specifically says it supplies 12 volts and 5 volts. The trick is in getting the 5 volts to the card itself. The pci-e 1x computer slot will supply 12 volts, but not 5 volts.

So where do you get the 5 volts internally for the card, so it can transfer the 5 volts to your hard drive through this cable? There are two methods:

Either: 1. from your unused motherboard 10-pin usb header, and they supply a usb connector cable for that purpose which mates with a 10-pin header on the card (one pin is always blocked off, on mobo and card, so you can't install it backward) or 2. from a floppy power connector.

If 1. you use the included usb connector that comes with the card - no problem - it will easily power two raw hard drives through two of these special cables, at the same time. But you may not have an available 10-pin usb motherboard header. So you may decide it's easier to run power to the card's 4-pin header. Finding floppy power in your computer case is easy - if your psu does not have the little 4-pin floppy power, just pick up a molex to floppy converter cable for a couple bucks - newegg has them. BUT - in that case, DO NOT PURCHASE MORE THAN ONE of these cables, because the floppy power gets current-limited by the time it goes through the card, for some unknown reason related to bad board design I guess, and while you can safely power ONE hard drive, with 5 and 12 volts, you CANNOT supply two hard drives simultaneously.

This is in regard to power, not signal. Both ports will supply esata signal - but we're talking 5 volt power. If you tried running two hard drives at the same time, and your 5 volt solution was to run floppy power to the card, you would probably experience what happened to me - both hard drives would start to suffer a limit on control board current inside the drive - brownouts - that would cause write errors, and create permanent irreparable bad sectors. It is worse than pulling the plug on your computer, which allows the hard drive to power off - this is intermittent brown power. I lost two brand new enterprise WD 1 TB drives - but nice RMA replace
