We have recently added a bunch of cryptocurrency payments options to our store at MinerParts. You can now buy your favorite PCIe risers and other parts using cryptocurrency, including:
When checking out from your shopping cart on MinerParts, just select the cryptocurrency payments option. You’ll then see a list of all the cryptocurrencies we accept. Click the currency you want to pay in, and the proper amount will automatically be calculated for you.
This is part of the wonderful service provided by CoinPayments.net. We highly recommend them if you are an ecommerce retailer wanting to accept crypto.
We’ve had a few people ask us recently if we ship our MinerParts including PCIe Risers, dual power supply cables and Bitcoin hardware wallets internationally.
Our current list of countries (that we’re aware of shipping too) are:
Canada, Brasil, Australia, Macedonia, Hungary, Germany, Netherlands, Norway, Sweden, Belgium, Czech Republic, Russia Federation, Singapore, Belarus, Chile, Argentina, Peru, South Africa, and Israel
A lot of our customers use shipping forwarders to order from the US. This adds an extra cost. No need to forward when you order parts from MinerParts. We can ship to you direct. We ship via USPS, UPS, FedEx, and DHL. If you don’t see a valid shipping option during checkout just send us a message. We’ll try to find a better shipping solution for you. We know that some shipping vendors are better than others depending on where you live.
Countries in BLUE are countries we have already shipped to.
Sometimes when we sell out of PCIe extenders on our website you can still buy them on Amazon because the inventory is in two different locations. Sometimes you can find them on our website when Amazon is sold out. If you can’t find what you’re looking for check the other site just in case!
You can see from the image above the 1x PCIe card that connects the USB cable to your motherboard. I’ve flipped both cards over so you can see the soldering on the back. These are both brand new risers taken straight out of the anti-static bag!
The green card is neat and tidy. Clearly whoever put it together took their time.
The black card is messy. It looks like extra solder is smeared on the back of the card.
One of our customers has over 3 GH of Ethereum mining equipment. He was the first person to tell us about the problems with the black risers. He was experiencing intermittent issues. We sent him some replacements and he compared the two. The green riser was superior.
Green risers clearly have a better build quality than the black ones. It is easy to see from the image at the top of this post. There are other minor deviations between black and green risers. We feel that in general, the build quality of the green risers is more professional and detailed. Green risers seem to be better quality and less likely to fry your equipment.
We’ve notified our vendor we only want to buy the green risers in the future!
We stand by all our product. If a vendor starts to send us a bad product we’ll find a new vendor or get the issue squared away. We’re also happy to ship replacements to our customers!
Typically if you have just one or two bad risers we’ll ship them free. If you have more than a couple we may ask you to send us back the old ones and we’ll ship you new ones. That way we can provide more details to our vendor about the problems. (Someone also tried to claim 20 out of 20 bad risers which we know isn’t possible! This helps prevent someone from abusing our refund policy!)
We’d love to know what you think? Have you had any problems with the green version 6 riser or the black version 6 riser?
Early builds for GPU mining rigs used the PCI-e 3 slots directly on the motherboard. Soon people realized they had extra PCI-e slots that they could use. Someone came up with the clever idea of creating a ribbon cable that would run from the PCI-e 1x slot on the MOBO to the 16x adapter on the end of the graphics card. This allowed you to use more slots in your MOBO. It allowed you to use cheaper MOBOs for mining. Finally, they allowed you to place the GPU a few inches above the MOBO which offered better air flow.
I later learned about powered ribbon cables. These supplied additional power via Molex connector. Since motherboards weren’t originally designed for 6 GPU mining rigs we needed to provide extra power to our ribbon cables.
I had been mining about a year when I heard of a new type of PCI riser cable. The USB 3.0 riser/extender card/cable. The USB cable was much longer than the ribbon risers. Typically the cable used is between 50 cm and 60 cm long. (20 – 24 inches.) It allowed for even greater flexibility when GPU mining.
This was the very first PCI-e USB riser I purchased for my own mining. I didn’t know it at the time but it was a version 1.0 PC-Ie riser. All I knew was that it was cheap to purchase. I needed to buy a bunch for my rigs so cheap was good.
I was new to PCI-e riser extender cables. I didn’t know anything about these so I had no idea this was a bad USB riser card to buy. When I received them and tried using them I quickly found several problems. The first problem was they had mounted the power cable underneath the USB port. It may be hard to see in this photo but it sticks out from the bottom of the circuit board. This isn’t really mounted securely to the circuit board. There are just 4 pins and when you push with any force to get the SATA power cable I popper the power right off the circuit board.
The second issue with the power was the power itself. Apparently it wasn’t rated for the amount of power we’re running through these. I later realized this was DANGEROUS. If you’re using these riser cards you need to check them immediately! These are actually photos from my old cards. They ALL look like this. They’re burning up!
The yellow cable is actually BROWN from the heat. The power connector itself is also scorched. This is clearly a problem. (You can also see those 4 pins in this photo that I found easily broke off.)
What I’ve learned since then is that there are differences in 1x to 16x USB 3.0 PCI-e powered riser extender cards. The first is that the better ones have 3 capacitors rather than 2 capacitors. You can see the little round capacitors in this photo comparing a version 1 riser with a version 6 riser.
I’m not sure about all the changes. A few you can notice right away. The materials used are clearly different. The power supply is no longer underneath the board. The circuit boards actually have a flat bottom and a piece of foam rubber covering them. The power supply is also reinforced to make sure it doesn’t easily snap off when you plug your Molex power connector into it.
I don’t know enough about all the other little circuitry that goes into making a circuit board. I don’t know the difference between version 3 and version 5. Someone even told me that the wires themselves aren’t really standard USB. You can’t swap them with regular USB cables. The wires inside the cable are re-wired. Much like how a crossover cable and a standard ethernet cable use the same cable but different wiring to the connectors. If someone can explain this better to me please leave a comment and let me know.
We don’t always know why the new version is available. It could be something as simple as they’re using a new manufacturer of the little components on the board itself. It could be in the wiring or in the cable. But I’ve come to trust that newer is usually better when buying PCI-e extender cables.
