Is it possible to power sata hard disk through PCI-e?

FYI, for anyone interested in that GP700 cable, disctech.com jacked up the price to $99. Dirty capitalists.

It would be nice to find part numbers for all the plugs and make up a quick wiring diagram to post here. I'd have to shut down my SAN, though. :(

The Molex connector in the middle will set the pin out for most of that. $100 though? Wow.

The only one that is questionable is the little 4 pin coming off the SATA 15 pin connector, the form factor does not look familiar to me. All the other plugs are standard affair though. EDIT: Oh it looks like the female end of the Optical Disk Drive plug.

Damn ... I mean, they have the supply and we have the demand, so I suppose they can charge whatever they want, but that's just bad.

For the record, the R710 I threw the GP700 into is running perfectly, and that USB 3.0 card I connected is working great as well. No complaints whatsoever :)

There is no molex on the R710s. My old 2950s had one in the front, though

Yeah, the cable is great. Mine was $30 shipped, which was barely worth it at the time. It's a handy cable, but I can't see spending $100 for it.
 
Get one of those PCI-E cards with USB power-only connectors? I haven't seen any with IDE power connectors. These cards are powered by the +12V from the PCI-E bus that's fed through a switching regulator that drops it to +5V for the USB connectors.
 
I bit on a refurb r710 for a VM host lab.

Im in the same boat as others... I plan to fill the 6 bays with drives for an array and run the OS off of one or 2 SSD's.

The only place I can find the G700 cable in stock is the $100 one at disctech.com, which I refuse to pay simply on principle.

Anyone know of another source or the current best alternative?

Thanks!

I am going to try and make a schematic of the harness and find the parts needed for it. Should be easy enough to replicate. The trouble is, the server I'm using it in hosts the storage for my entire environment. Next time I take it down for maintenance (maybe tonight), I'll get a good look at the cable and see if I can find the plugs online.

Dude that would be awesome if you could pull this off. It doesnt look like it would be all that complicated, but still would be a bit of work and if by chance one gets just one wire wrong there could be alot of smoke and the stinky smell of fried drives.

I (and other R710 owners) would be in your debt for something like this.

If it ends up being not that difficult/expensive to build, I would probably be willing to entertain the idea of making a handful of them and offering them to [H] members.
 
It looks like all you would need are these 3 parts:
And then move the crimped pins on the "p4" (12v CPU cable, whatever its called) if needed.

If the plugs are not the right shape (

etc.) noting an xacto blade cant fix.

I ordered the parts to make 5 off eBay ($20 shipped). You'd have to solder in the DVD plug, if you needed it.

Hi All,

Great thread! As i have the exact same (power) problem for my R710's.

I thought i was smart and bought a pair of these:

https://www.allekabels.nl/sata-kabel/1763/1082636/sata-naar-slim-sata-verloopstekker.html

So i could connect the slimline sata from the DVD drive into the slimsata side of the adapter and then hookup an SSD to the normal sata side of the adpter. All connections fit but the SSD is not getting any power so it doesn't work and i don't know why. Maybe someone with better knowledge about this can explain why this adapter isn't working? Wrong voltage maybe?

ps. i tried multiple adapters but they all don't work.

Kind regards,
Caspar
 
wow you guys sure can over complicate things. the CDROM has a power connector on it. i added one of these

or you could just do this as i never use the optical drive anyways.
