new additional PSU and motherboard! suggestions please.

[mlouca]

I have completed my first rig. The psu only was able to support two cards because it didnt have enough slots. I have 3 6970s remaining, i want to know which motherboard can someone suggest for those specific cards and which PSU unit that will actually have enough slots for all 3 cards to get power. Thanks guys!

We need to know what type of motherboard you are replacing so we can actually recommend you one...

and what u mean "slots" on the psu

Motherboard   MB ASUS|P8P67 WS REVOLUTION REV 3.0
Power Supply   Ultra X4 1600-Watt Modular Power Supply - 135mm Fan, ATX

each card needs to be connected to the PSU correct? so the PSU came with 3 sata wires because it only has 3 slots for those sata wires (hopefully they are called sata and i am not mistaken). Well one sata is used up, so we are left with only two for the graphic cards. is there any PSU unit that has 4-5 or 6 SATA wire slots so you can connect more than 3 items to it? and also which motherboard do you recommend i purchase i have 3 6970s. i am looking to keep the rig i built the way it is, and just get a new motherboard and a new psu unit for the additional 3 6970s that i have

Add another PSU, one of the 450W modular juice boxes from Newegg. Use it just for 1 card and nothing else, since it has more than enough power and is only $30-40.

Problem is i have an additional 3 cards. which motherboard best suits 3 6970 and which psu unit can support all 3 cards..

i realize that im not running 6970s...but i am running x2 5830s and x1 5870, on one board. so heres my input.

im using -
**Thermaltake Black Widow W0319RU 850W ATX 12V - newegg.com $130 (this PSU only comes with 4 PCIE x6 connectors, but using the additional molex and the included (2) x6PCIEs included with one of the GPUs the 3rd card is powered
**ASRock 890GX EXTREME4 AM3 AMD - newegg.com $130 SOLD OUT

with both cards over clocked im pulling on average 550W (only 65W AMD CPU)

this MBoard/PSU setup up should work good for you too...

I assume you mean PCI-E power connectors and not SATA.  There's no SATA anything on your video card.

Either get another PSU or just some simple PCI-E power splitters.  There's some that split from molex or even from a current PCI-E connector so you can attach more devices.  Sure your current PSU has plenty of plain regular molex being unused.

That's good as long as you know your PSU can handle the total load.  I'm powering 4 6870s on a 1000w just fine.  Do 6970s require that much more power?  (I don't know) but I would guess that your 1600w would be enough for it.  Sure someone else would chime if I'm mistaken.  *shrug*

What kind of motherboard are you using, and how many mhashes per second are you getting? atleast 400?
