Topic: Server PSU-powered GPU rig packages! Pico's, Risers, adapter cables, etc. - page 5. (Read 15924 times)

Hey Finksy, was looking at your pico and planning some stuff before I buy, and have a question, where does that green wire go that I see in your photos? Or does it just dangle around?

GPU packages are currently on hold, I am nearly out of stock on splitter cables.  I will be getting more hopefully in short order.  Please stay tuned, and thank you for your patience.

Finksy

I am getting around to replying to all PM's, so thank you for your patience.  Has been a very busy weekend.  I have updated the packages to now include a couple 36" PCIe cables with each package to help reach the furthest GPU's.  Price has been updated to reflect the slightly more expensive cables. 

I am just finishing replying to the last few PM's.  If I have not replied to your PM for quotation or questions in the next hour or two, please feel free to send me another PM and I apologize for the oversight.  PM inbox has been flooded.

The PSU's I offer only work on 200+V, yes.  Unfortunately I do not carry any PSU's that work on 110/120V, but there are many people on the forums that do.  Feel free to hit up sidehack (unless he's too busy with his plethora of projects), HolyScott on here (holybitcoin.com) also carries some common slot and similar 120V PSU's that will work just fine with these GPU packages.  All you need is a PSU with PCIe connectors on it to take advantage of the components in these GPU packages.


PM'd back


Cost savings vs having to purchase 1000+W ATX Power supplies with adequate cables to power GPU rigs such as these.  For example, to power a rig with 6x R9 390 GPU's, you would need something like the EVGA 1600 G2 to match the DPS-4K/IBM 2880W in efficiency or an EVGA 1600 T2 to match the IBM 2980W in efficiency.  The 2880/2980W PSU's could power 2 of these rigs (or 3x RX series rigs) without problem, the DPS-4K could power 3 of the 390 rigs (4x RX series rigs) without problem.  Comes down to $$$, efficiency, reliability, modularity, etc.  Also, with the PSU's I offer, you have the breakout board, cables & components.  And, if you ever do happen to have a PSU failure, you only need to purchase the PSU itself, which doesn't make up that significant of a portion of the cost in total. But as everyone is aware, server PSU's are more reliable, and stable as far as voltage to the plug in comparison to the average ATX PSU.

What are the advantages to getting these cables?

Hey, i've sent you a pm about some gpu risers, if you haven't received them i wanted to ask about the price + shipping for 10 risers to 11413

Finksy, any special packages for people that only have 110/120v? All those PSU I see requires like 220/240v.

Another PSU i know is HP DPS-1200FB, but that has only a rated 900w on 110/120v and understand that it can handle higher watts, but prefer not to put max load on it if my rig consumes almost 1000watts.

Any other solutions?

Thanks !

@Finksy, thanks for the quick response and yes that did answer my question.  After I posed the original question, I somewhat figured that was what the 6+2 pin PCIe splitter was going to be used for, but the picture and description really did clarify things.  This is going to be an amazing cost effective and efficient solution for powering GPU rigs.

super,

The package includes 6+2pin PCIe splitters.  There are now pictures to show them up top, should help to clarify.  They take a 6-pin PCIe cable in and split to 2x 8-pin PCIe connectors for GPU's.  For the RX series GPU's this is safe, as the wattage drawn through the PCIe connectors on the 470/480 cards is only about 80-90 watts MAX in general.  The PCIe cables are 16awg, and can handle upwards of 250W without problem.  Hope that answers your question!

Myffas,

I have not used the DPS-2500BB PSU's, but the 4K boards are more than capable of handling the extra wattage.  The higher efficiency is also a good selling point.

I do have PDU's, if you look in either my IBM 2880W or DPS-4kW PSU threads you will see that I carry both 30A (24 continuous) and 50A (40A continuous) PDU's.  I also have some packages including PDU's for multiple PSU setups.  PM me when you're ready to talk about that project, I'll give you my number and on peut parler.


Replying to everyone as quickly as I can, thank you for your patience!


Herb,

I've now posted pictures to better understand the setup.  The Pico PSU's come with a 4-pin ATX connector on them, but I'm of the opinion that there's no point in drawing extra 12V wattage through the Pico PSU when we have a more reliable source as it is -6-pin PCIe cables from breakout board- and it doesn't require any more slots.  So that's why I include a 6-pin PCIe to 8-pin EPS patch cable together to power the motherboard directly.  For the Biostar's you can just use the 4-pin ATX connector on the Pico and use the extra PCIe connector for something else low-wattage like a riser, there's no harm in doing so.  Here is how the Pico PSU looks connected to a motherboard (powered by 1 PCIe connector from motherboard):

@Finksy – Sent you a PM, please take a look at it when you get a chance.

I’ve posted my question publicly, since I have a feeling it might be a common one.  For the graphics cards that require an 8-pin PCIe connector (most of the non-reference cards or for example the popular Sapphire Nitro+ RX 480), what is the safest and cost effective methodology to attach these to your PSU breakout boards?  Is it safe to only populate 6 of the 8 pins on the graphics card itself or is that a potential fire hazard?  I know they sell an adapter, some cards even come with it, that combines 2 x 6-pin PCIe female connectors to a single 8-pin male connector, but that solution seems overkill to me.

Edit: I may have answered my own question.  In the kits, can you post a picture or describe the 6+2pin PCIe splitters?  Does this take a single 6-pin PCIe female connector in and split to two 6+2 pin PCIe male connectors?  If that’s the case, is it safe to power two RX-480 graphics cards from a single 6-pin PCIe connector.  Not sure what the power consumption is through the 8-pin PCIe port because I know that some of the power comes from the riser itself.

yes

Prices are in USD ?

I need a few Pico PSU. My motherboard require an 8 Pinn connectors. Not sure if it comes with the 8 Pins by default.

The H81 Pro BTC is 8 PIN and i didn't receive my Biostar TB85 but it looks like an 4 Pins.

EDIT: Do we absolutely need an external power supply for the Pico ? I'm sure I understand the PCIe to EPS adapter assembly with barrel jack pig-tailed for powering Pico PSU correctly

Thanks

@Finsky - Sent a PM please take a look at 

This is a very nice addition to the products you already offer. Any plan to also go into the PDU direction? This would make your shop a one stop for all power needs. I may also be interested about the DPS-2500BB PSU any opinion on these? I like that trey are more efficient and also provide slightly more power.

Btw the project we discuss about is now only a few week ahead.

Whoops! Typo, my bad.  Thanks for pointing that out.

Pictures of risers/Pico updated.  Rest of pictures will be up shortly

Hey Finksy, can i have pictures of the risers, the current pictures are invalid.

Finksy



i think here is mistake. 2880 can handle up to 2-3 rigs and 4KW can handle full 4 rigs. edit post in beginning to dont make some troubles for buyers. want to buy some of this so this will be my fixing in this topic
