Topic: Current best powered risers available? - page 4. (Read 1830 times)

My friend has a farm and never had a problem with the 3 capacitors. Not even one from hundreds.

I also insist on four capacitors. I have some risers on hand that bought last time with four capacitors, it is much stable compared to three capacitors riser.

The single to 6 plugs work (had them plugged into an undervolted SP20) but they do get a little bit hot if you're putting a lot of power through em. I would suggest the dual molex connectors whenever possible just for security. If you do use the single plug connectors, make sure the cables aren't getting too warm.

Hmm.. every where i looked said it was preferable to use one per chain but two was fine *shrugs*

I have done plenty of molex 5v fan mods in my day. Doesn't seem like it would be much harder than that. I'll prob just end up getting 6 of the ones with all the connectors though.

 It is - no "reach around AND UNDER issues, or "pull the card to get to it" issues.

 Shouldn't matter on a reliable rig though.

 2 molex risers per chain CAN be an issue - the connector is fine, the WIRING is often not enough to support 150 watts and in the case of EVGA they specify that the connection ON THE POWER SUPPLY END is only rated for 75.

 It's possible to modify a "dual molex to PCI-E" adapter to use one MOLEX, but I don't recommend it unless you're an experienced tech and KNOW what you are doing.
 It's just easier to plug BOTH molex into the same MOLEX "string" from the power supply - since it's only ONE riser, it's not an "overload" issue.

 There ARE folks that make "single MOLEX to PCI-E 6-pin" adapters though - I've got a few around that apparently were provided with video cards at some point, and went into my "keep this, it might be useful eventually" box.

Looks good. Miles better than I thought it would have. Actially looks better for getting access than the ones with the power at the back of the riser

I have a bunch of these in 6-7 X 1080ti setups crammed into a Rosewill 4U server chassis and they are fine for clearance;.

Have you got a picture of these risers fitted with a gpu? It looks really tight for a power connector down that side.

Thanks

These are shit ones i am using now. https://i.imgur.com/Ruzyv65.jpg

I am running 2 per Molex chain though. Figure its fine for 1060s at 80%

So are you saying i can mod dual molex to 6pin to single molex to 6pin? I have a tone of them. That would make buying risers MUCH easier.

I can only find single molex to 6pin, for a reasonable price, from China.. Dont want to wait that long. :/

 There IS such a thing, but they're not common.

 Since you probably should only be running 1 riser from a molex string though, it's really not hard to plug both molex connectors into that one string.

 EVGA in specific has stated on their web site in the forums that their "peripheral" connections are only rated 75 watts per STRING.

 I've NEVER seen interference with the MOLEX or PCI-E connectors on the "3 way cards" with a backplate GPU - though I can see a possibility of the "latch" on the PCI-E power cable being a tight fit.
 If I'm going to use PCI-E power to the riser though, I just go with a straight PCI-E riser not a 3-way.

 MY main issue is they put the dangerous and worthless SATA power connector on the end of the card, where it's easier to route the riser power to - I'd rather see the MOLEX connector there.

 The right-angle adapter IS a bit annoying, but there are some folks that offer the traditional "straight out" adapter with those risers.
 I CAN see them being an issue on the B250 Mining Expert for all but ONE row of 1x slots as you point out, but they shouldn't be a significant issue on any other motherboard I am aware of.

Id buy the 6pin riser but its hard to find inexpensive single molex to 6pin. Kinda weird that there are so many single sata to 6pin abut hardly any single molex. They are all dual molex. :/

I think it depends on what you're trying to do - generally speaking mining doesn't put any real stress on the PCI bus in terms of bandwidth, and typically bandwidth (speed) is what you're going to loose over longer cable runs.  Probably the two biggest issues you run into with cable length is signal loss and interference - so you can at least be relatively sure that a higher quality cable is going to have better insulation.  Whether or not it's going to help in the signal loss department is a bit more iffy.

I've literally built 100's of rigs using those exact 3ft'ers I've linked to without any issues (you may have seen my custom miner enclosures, they all use these cables).



Personally I hate this design of risers - it does just about everything wrong in my opinion.  First, the molex and PCIe connectors are located such that they almost always interfere with the card or sit right up against the heatsink of the card, which it terrible in my opinion - personally I only buy the ones with the 6-pin PCIe connector for power, and then just use an adapter if I need to get it from something else.  The slot connector has a right-angle plug on it, so on smaller builds with just a couple cards on a traditional motherboard it won't be an issue - but on a larger board like the Asus B250 Mining Expert you can't use these because the small slots all overlap - only the typical upright ones work.  Beyond that it's fine. 

 No opinion - but I'll point out that Newegg carries 6-packs of the Mintcell version of those for $7 or $8 more, shipped from the USA instead of shipped from China.

this is correct..I have molex risers version 3 from 2013, mining for 4 years already.


not just the usb connectors sometimes there are white stuff under the riser board...that white stuff is something that is left after soldering, this can conduct electricity and cause problems, people should check and scrub them off before using just to make sure.

I got these https://www.amazon.com/gp/product/B076MP4M8W/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 from amazon last month to try and I think there great everyone worked 100% not like others I've ordered and 1 or 2 either doesn't work or weeks down the road you start having trouble plus there's multiple was of powering them

I actually did buy and try to use these. It gave me all sorts of issues where the video card wouldn't even show up at all, and some would. The ones that did, when I went to go mine, it would lock up the system. I switched to the shorter included mintcell cables and it solved those problems.

I also found a website that shows where longer USB cables puts strain on the system itself killing speeds it can transfer and that 1.5ft was pretty much the longest you could use.


So I am curious as to how you got 3ft to work reliably.

Thanks guys.


Thanks again. I will try to find those on Amazon.ca. Failing that what about these?

I really wanted to try an Onda board. The one with the baked in Celleron. But i didn't want to wait for shipping from china :/

These are the ones I always used:

They aren't the cheapest, but they're not bad and super reliable - I don't think I had a single one not work.  For my last build 3ft was the ideal length, but they sell smaller ones that might be better for most people.

I've tried all those - Colorful, Onda, etc... TBH I love them all, you really can't go wrong with any of them, even some of the weaker ones.

Bad connections can happen with ANY connector type, especially if you plug and unplug the connector a lot.
Molex one downside is that it can be a bit of a pain sometimes to get the pins aligned properly when you push the connector into the socket - if you do that with care you should never have an issue.

 One thing I HAVE noticed is that a lot of riser makers seem to "cheap out" on the soldering job, I've seen a few MOLEX risers where the MOLEX connector wasn't soldered AT ALL, just a press fit - which is a DEFINITE recipie for failure on a frequent basis.

 Version 6 should be the MINIMUM riser generation to consider - not that they're more efficient, but they're more RELIABLE than anything older.
