Title: x16-x16 riser cable NOT to by Post by: drknark on June 27, 2011, 09:19:48 PM I bought some cables from http://www.b2c-support.com/pcie-pciexpress-16x-riser-card-extender-ribbon-cable-p-4154.html (http://www.b2c-support.com/pcie-pciexpress-16x-riser-card-extender-ribbon-cable-p-4154.html).
The first two out of the five I tried refused to recognize the card. The third one however, is when it gets really interesting.. I plugged it in, standard procedure. Made sure there was no possibility of shortcircuiting the exposed (why exposed?) contact points. So I'm all set up and ready to go. I flip the PSU into on, and hit the power button. First I noticed some really thin smoke, it was barely visible. Then the smell of burning plastic and suddenly a lot more smoke. This is what I pulled out: http://i1081.photobucket.com/albums/j349/drknark/IMG_0517.jpg Luckily all my hardware survived. Since their support ignored me I had to issue a paypal dispute to get my money back. So don't buy cables from that site :) I would even be wary of similar looking cables at other sites, might be the same manufacturer.

*blinks* one.... two.... *blinks* *blinks* Huh? *** Edit *** Aha! I get it now! 0_o Title: Re: x16-x16 riser cable NOT to by Post by: Jack of Diamonds on June 28, 2011, 03:21:22 PM Buy from Cablesaurus, these work 100% fine even in 24/7 use, and I bought a version with a Molex power feeder injected in the ribbon = even less risk of something like that.
BTW, my 4th card wasn't detected either when using the riser from CS, until I plugged in the extra power cable. Title: Re: x16-x16 riser cable NOT to by Post by: drknark on June 28, 2011, 04:16:52 PM Yeah, I tried one from cablesaurus after this incident. It works fine, so I have ordered a bunch of them now :)
Title: Re: x16-x16 riser cable NOT to by Post by: SgtSpike on June 28, 2011, 05:09:19 PM Yikes! :o
I bought mine (just a single one) from that cryptoanarchy store, and it works great. Also bought some resistors from them... good experience all around though! Title: Re: x16-x16 riser cable NOT to by Post by: zerokwel on June 28, 2011, 05:10:59 PM Lucky escape. Could of killed hardware
For me if I ever need anything I will use cablesaurus Its worth the extra not to fry my hardware. Title: Re: x16-x16 riser cable NOT to by Post by: airdata on June 28, 2011, 07:02:25 PM i got 4 $5 16-16's recently and couldn't get my cards to show up.
Got 3 other x1-x16's today and cards showed up right away. All cables I've gotten from cablesaurus have worked fine. Title: Re: x16-x16 riser cable NOT to by Post by: hugolp on June 28, 2011, 07:10:32 PM Another satisfied cablesaurus costumer here. And you can pay with bitcoins.
Title: Re: x16-x16 riser cable NOT to by Post by: MaGNeT on June 29, 2011, 09:43:11 PM When I look at the picture I think one of the connectors wasn't aligned correctly.
And when you look at the upper left connector it even looks like 2 pins are bent because there isn't a hole where they fit in. http://i146.photobucket.com/albums/r254/MaGNeT76/IMG_05171.jpg Title: Re: x16-x16 riser cable NOT to by Post by: teflone on June 29, 2011, 11:42:55 PM When I look at the picture I think one of the connectors wasn't aligned correctly.

Title: Re: x16-x16 riser cable NOT to by Post by: drknark on July 03, 2011, 09:17:15 AM I also think you messed this one up yourself, there are multiple loops in a slot.. looks like you shorted out your pwr supply +v Messed it up how? I'm confused. The connectors on each side were already mounted when I got the cable. The pci-e connectors seemed to fit tightly in the slot / on the card, I don't see how I could have gotten that wrong. Title: Re: x16-x16 riser cable NOT to by Post by: malevolent on July 03, 2011, 02:38:38 PM What GPU(s) and PSU(s) were you using?
Title: Re: x16-x16 riser cable NOT to by Post by: erek on July 03, 2011, 10:21:43 PM what is the point of these riser cables? like why do you guys want to use them??
Title: Re: x16-x16 riser cable NOT to by Post by: malevolent on July 04, 2011, 01:31:30 AM Better airflow.
Without them, in many motherboards no more than 2-3 cards would fit. Title: Re: x16-x16 riser cable NOT to by Post by: Jack of Diamonds on July 04, 2011, 01:36:07 AM what is the point of these riser cables? like why do you guys want to use them?? Motherboards usually have horribly placed PCI-e slots. Maybe to discourage the use of tons of GPU's. With risers, you can actually utilize all 8 PCI-e slots on a board like MSI BB Marshall. Which would be impossible normally, because a single card (even a 5770) takes 2 slots on the board. No comment on whether it's safe to draw 8x75 (600W) from the board 24/7. Title: Re: x16-x16 riser cable NOT to by Post by: drknark on July 04, 2011, 12:15:28 PM What GPU(s) and PSU(s) were you using? The test was done (one cable at a time) with a Corsair HX750 and a 5750. Using other cards where the cables were supposed to go finally of course. Title: Re: x16-x16 riser cable NOT to by Post by: Inaba on July 05, 2011, 04:21:58 AM No comment on whether it's safe to draw 8x75 (600W) from the board 24/7. It's not. You'll fry all sorts of good stuff. Title: Re: x16-x16 riser cable NOT to by Post by: hennessy on July 05, 2011, 08:13:22 AM Are those some old recycled IDE cables???
Title: Re: x16-x16 riser cable NOT to by Post by: MaGNeT on July 05, 2011, 08:21:03 PM Are those some old recycled IDE cables??? Not if you count the pins ;) Title: Re: x16-x16 riser cable NOT to by Post by: 1bitc0inplz on July 06, 2011, 01:18:02 AM what is the point of these riser cables? like why do you guys want to use them?? Not the pictured cable, but another reason for riser cables is to run a GPU off a 1x slot. Even low end motherboards have at least 1 or 2 1x PCIe slots in addition to one or two 16x slots.... using all the available slots means more bang for your $. Title: Re: x16-x16 riser cable NOT to by Post by: Pentium100 on July 09, 2011, 05:41:16 AM So I'm all set up and ready to go. I flip the PSU into on, and hit the power button. First I noticed some really thin smoke, it was barely visible. Then the smell of burning plastic and suddenly a lot more smoke. This is what I pulled out: I would do one of two things:1. Find out which pins are used to transfer the power to the card and solder thicker wires to them. 2. Solder in a molex power connector on the "card" end of the extender, disconnect the power wires coming from the motherboard. The second option can also be used to connect a lot of cards to a motherboard without frying the motherboard. |
