I am interested in purchasing one "PCIe x1 to 16x Adapter Modified Riser Extender Cable" at 2 BTC shipped to the US. Let me know how you want to proceed with this deal.

I bought several of the 1x to 16x cables. They arrived very quickly and work great. I'm making use of a bunch of 1x slots that I thought couldn't be used due to location and connector size.

There will be a 48 hour delay on shipment of 1x Extenders, 1x -> 16x Adapters, and 1x Extenders w/ Molex. Waiting on additional inventory that hasn't came in yet. Feel free to place your orders and they will be sent out in the order received, hopefully sooner than expected.
I'm preparing Cablesaurus.com with a Bitcoin shopping cart, launching tomorrow morning, which will allow Bitcoin & Paypal purchases directly from my shopping cart. Stay tuned.

Ordered cables arrived and all worked as advertised, 1x & 16x w/ Molex power.
Good service.

I assume you could use these cable mods to run your PCI'e cards from a different PSU to your system PSU?
If you're using a PSU not grounded to the motherboard, do not utilize a cable with modification. Make sure any secondary PSU to be used would be grounded through the motherboard. So if we are not using any modified cables, there is no need for grounding a second (or third) PSU to the motherboard? I have used the paperclip trick to put a second 400W PSU to power 1/2 of a 6990. The PSU is sitting on the table and have been getting pretty good performance for the last 24hrs. Am I missing something / doing something wrong?

Nope, from what you've described you're in good shape.

If you are powering anything plugged directly into the motherboard with a second power supply, you have a potential grounding problem. The kind of problem I've described here is not one that will blow up a card immediately and you'll instantly know there's a problem. The grounding problem of this nature will slowly burn out components over time and/or shorten the life of the equipment. The questions that arise then: Is the problem is pronounced enough to worry about? e.g. Will it shorten the life of the equipment enough that you care. Is grounding to the case sufficient to make the ground differential acceptable? Which (if any) pins on a modified cable need to be grounded to a common ground? Personally, I would not try using two PSUs on anything expensive until I understood exactly what the consequences are. It's entirely possible that you can burn out your card, motherboard, or PSU or any combination thereof. It's also entirely possible that this fear is completely groundless (pun intended) and there's no need to worry at all. If you want to use two PSUs, the least you should do is make the grounds common by combining the two ground pins on the two PSUs. I'm not sure this will solve the problem or be snake oil, though. But at least it's something.

Assuming the 'COMMON' or 0V pins are indeed connected to ground (which in my very limited knowledge of electronics I'd assume) then wouldn't the hack to make the slave PSU power on with the master one automagically solve this? We are connecting one PWRON and one COMMON pin across the PSUs.

So I did some more research on this... came across this, which is encouraging: ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fimg189.imageshack.us%2Fimg189%2F7715%2F2024pinout.jpg&t=665&c=LjmjlrMujGuCBg) Yes, connect the "master" PSU's 20/24-pin to the motherboard and connect two jumper wires between it and the "slave" PSU. Referring to the pin-out diagram above, connect green to green and any black to any black on the two units and the slave will power on and off when the master does with the front chassis switch. The slave units are usually used for their additional 12V capacity to power graphics cards, fans, water pumps and the like but should also be used to power a couple of drives, either optical or hard, too. This will put a small load on the 5V rail and less stress on the PSU trying to deliver a 12V only load. Instead of using drives for a 5V load you can make a "dummy load" with cheap resistors. Two 10-ohm 10W ceramic resistors or a single 5-ohm 10W aluminum will put a 1A load on a 5V circuit and dissipate ~5W of heat.
Ready made dual PSU adapters are sold by Ultra and Lian Li and also come bundled with Cooler Master dual PSU capable tower cases. Performance-pcs.com selling the Ultra adapter does ship worldwide.

By using the mentioned "hack" we will be connecting one "COMMON" line along with the "PS_ON". This is ground(ed), right? Without seeing your exact set-up, I'd say, yes, that should do it.

Ordered a 1x to 16x adaptor and 2 day shipping. Got it 2 days later. Works as advertised. Great service. Would recommend.

Can you daisy chain these together? I've already got a case and was thinking about sticking a couple of GPUS on the outside panel but I would need longer then 7 inches.
