This is relevant to my interests.  But yeah, how is power handled there?

If you're searching these lines for a point, you've probably missed it.  There was never anything there in the first place.

Let me know what you find out.  It's pretty interesting, though I'd like to not have to kill the CPU fan. 

Also, unrelated, plz send Thai chick.  Doesn't have to be the one in picture, just of similar quality.

Yeah. I made a post about this way back but nobody seemed to notice it Undecided

I am REALLY interested in this type of setup. Seems ideal if you want to avoid dual GPU cards like 7990s.

Keep us posted !

If i remember correct, there is one, or two molex 5-12V on this board. so i wouldent worry about power.
It`s quiet nice, but not cheep. best thing is, you can buy cheepest MB on market with PCIe

There are TWO 6 pin power connectors that lead directly to the PCIe slots.

Since this was designed in mind with BTC mining, I think the product is quite nice and qualitative ( uses PLX chip for PCIe switching etc. )

But somebody needs to test it.

I don't read/speak Chinese, but if someone can order/sell me one, I will take a chance and report back as I need something like this.

Yeah that thing costs $2000 while this Chinese thing costs $200.

Worth a try IMHO.

Something I didn't notice from the first thread.

Anyone notice the slot spacing in the photos?

In the photo of blank board it looks like the slots are paired right next to each other.
Then look at the photo of the board with 7 cards loaded.

Is it just me or does the spacing not match?  I only noticed because the spacing of the slots seems foolish.  Every second card is crammed right next to the adjacent card and then there is a giant gap to the next card.

Look again at pictures.

Design is perfect.

Slots are facing opposite ways so GPU fans got tons of breathing space.

It really is thought out.

Someone needs to let us buy them in the EU and test it out.

I think the idea is to have the cards alternating front to back to allow space for airflow, actually quite a good idea, be nice to get 1 or 2 imported to the uk

Have i helped? 1Gm9NMJ2qn2XU1qc4Mps9GSCGe5cdetmpv

Yeah. I wonder how much the tax will be when importing these.

There is like a limit for products under $60 USD or something but above that there will be duty and VAT to be paid I think Cry

Mine only cost me $600.00... Dual LV Xeon SHB another $200... 8 GB RAM $30... 2360W server PSU $99...
