Older Motherboard will work??

[QuantumCoinz]

Hi everyone, this is my first post although I've read a million posts here (which only covers about 1% of what is probably posted on this forum!)

I've been reading so much stuff/opinions on mining so I thought I would give it a try, why not. I'm trying to keep my budget down and starting out I have an old Asus P5Q motherboard.
https://www.asus.com/Motherboards/P5Q/

It does have a total of 3 PCIE slots, which I assume are fine for mining.

I am purchasing 3xrx470 cards for this board but I only have a 500W PSU at the moment.   

I suppose my primary questions are

1) Will this board support mining (BIOS issues? other?)
2) I need risers yes, however, will I run into any compatibility issues with the rx470s?
3) Will a 500w PSU support 3x470s?
4) If i need a new PSU, will I need to buy an older PSU to support this MB?

thanks in advance for all replies and considerations for your time.

Sigh...
This section is for BITCOIN mining only and BTC mining has long been ASIC-only 
Please move this or repost in the altcoin section https://bitcointalk.org/index.php?board=160.0 for usable answers to you question.

I asked mods to move this.


what cpu is in that mobo

what ram is in that mobo

laslty make and model of the psu---- I think 2 cards max.  but do not rush  to buy  a psu since the cpu and mobo may not work.

My "test" Ethereum miner is one of these:  https://www.asus.com/Motherboards/P5N7AVM/

LGA775, it's got a dual core Pentium on it, latest bios. I'm running 2 risers to the 2 PCIE slots with some 4GB RX480s on it, getting around 26 Mh/sec on each heavily underclocked on the GPU and undervolted, pulling around 325 watts at the wall. Not ideal in any case, but it's an old box and it works and slightly spreads my risk across 2 systems in my hobby mining farm. Windows 10 Pro, 6GB of RAM, I was initially running it on 2GB of RAM with sgminer, had to get over 2 to get to Claymore which is what I run now.

I have another rig that's much more modern, one of the Biostar LG1150 boards, but like Phil said give it a shot with 2 and see.    One of these days I'll move one of these low end cards to that other rig to see if it mines a little faster, but I'm making that tradeoff of having my stuff split between systems so something is always up and mining when I'm tinkering or having a stability problem.

This motherboard was once my Home theater PC. I've been proud it hasn't hit the recycler yet.
