starting mining

[mustar]

Hello,

I have a computer with aan Asus Z97-A motherboard https://content.hwigroup.net/images/products_xl/215518/asus-z97-a.jpg and a gtx 1070 and a Cooler Master HAF 922 computercase.
I was thinking to buy 2 more gtx1070 and a new psu and start mining.
Is it possible to do this 3 gpu mining with my motherboard in my computercase?
Thank you!

I'm pretty sure you would be able to get three cards working on that motherboard. Given it only has one PCI-E x16 v3.0 slot, you should use 1x powered risers for the other two cards. Here is a post from someone that has 5 cards working on that board.

I don't want to use risers, I want to fit all 3 cards in the computer case, using the two pci-e 3.0 and the pci-e 2.0.

The PCI-E v3.0 cards will usually draw more power from the slot. The newer PCI-E specifications are able to deliver more power through the slot. You may burn up your motherboard using a PCI-E v3 card in a PCI-E v2 slot for mining under constant load.

The mobo has more than 2 year warranity. Also, in mining, the gtx 1070 takes around 140w, most from the 8pin pci-e connector?
Also more power hunry gpus like gtx 580 were on pci-e 2.0.

It depends on how the card is configured to draw it's power. Older PCI-E v2.0 cards got most of their power from the VGA power connector. Since the v3.0 specification allows for more power drawn from the slot, v3.0 cards tend to draw more power from the slot. In fact some PCI-E v3.0 video cards state they require a v3.0 slot. When the RX 480's came out, many gamers were burning up their motherboards from just gaming with the card.

Ok. I'll buy only 1 more gpu and mine with two gtx 1070, without replacing the psu.
Thank you!
