Hi everyone,

I'm new to bitcoin mining -also to this forum-, and I'd like to put to work a modest mining rig. I'm choosing the following set up:

* Radeon HD 5850 Xtreme - 1 GB GDDR5 - PCI-Express 2.1 (3 units)
* AMD ASUS M4A79T Deluxe AM3 DDR3 PCX
* 1350W Thermaltake Toughpower ST
* AMD Phenom II X4 965 3.4GHZ SKT AM3 6MB Black Edition

I've choosen this motherboard because it includes 4 PCIx16 slots. But I'm not sure what cooling and case choose, considering that dropping the case is not an option in my case. I've checked CoolMaster, but I don't know which flavour would suit this set up either. Could you give me some clues?

Thanks and happy mining! Smiley

You might want to actually do some research and read the plethora of information available on these boards.
There are also various spreadsheets to help you calculate if its more profitable to buy or mine.
Your intended setup seems overkill and expensive, you might not ever recoup your costs.

MB: ASRock 880G Extreme3
CPU: Sempron 140 (why anything else?)
RAM: 1 stick of DDR3 2GB Kingston ValueRAM

Also, 1350W PSY is overkill for a 3x5850 rig. a good solid 800W+ will do you more than fine.

Thank you a lot for the quick amd helpful answers!

MiningBuddy: I've done my homework, but I still have some doubts, so I thought asking to those who know about this would be better than spend unwisely. In fact, as you have stated, my intended set up is overkill. I still need ot look up those spreadheets though.

Noobboon: I know, I chose that processor because I want to use the rig for other purposes for one or two hours a day. I've included it in the list in order to check if there could be any incompatibility with other components.

Atroxes: thanks, I did't know about the PSU; I checked the wiki examples and apparently they use 2300W or so!

Thanks again.

Im running 3 sapphire HD5850's.  I like'em!

I am using an Antec 300 case, Gigabyte GA-MA770T-UD3 motherboard, and a 600W power supply that is helped by an ePOWER EP-450CD 450W JuiceBox.
I am also using a Sempron 140 processer and 2 gig of ram.  The Semprons are nice little procs for the price, I use this one for basic stuff like browsing, email and junk while mining in Ubuntu.

Heres some links to help:
I bought my case from Amazon for $59 bucks and it shipped free:  http://amzn.to/lgHjr4

Sempron 140 for $37 bucks: http://amzn.to/ilK3X3

2 Gig ram for $21 bucks: http://amzn.to/mom2Wr

I am using this 600 watt power supply that I picked up for $30.  Its a damn good PSU and has served me well.  Has 2 fans, and runs cool with the load:  http://amzn.to/iPey67

I bought my juicebox from Amazon as well, but its sold out and the next one is 50 bucks, but I found it on newegg cheaper for $24: http://www.newegg.com/Product/Product.aspx?Item=N82E16817101044&Tpk=juicebox

Do you have a Kill-A-Watt meter?
What sort of efficiency does the Juice Box, or that Diablotek PSU get?

Donations welcome, not required.
I'll be honest, any donations aren't used for a good cause, they go directly to booze, food, herbal substances Wink, and computer hardware.
I will squander the money, but hell, at least you know one person is having a good time.

$30 PSU?
I can imagine your house burning........


DUDE, don't mislead others

A GOOD PSU is extremely, fatally important.

For those who have 3+ GPU, get a 750W+ PSU. like antec, corsair...

Its been a good PSU what can I say dude.  Its only powering one of the 5850's.  The juicebox is powering the other 2.

My Killawatt meter is only showing about 650 watts total consumption from the PSU, juicebox, and my 19" LCD (in standby).

The diablotek has alot of good reviews as well.  Its up to you, but my PSU combo is working great!

just my 2 cents... Ive got 4x sapphire 5850s on an AM3 motherboard (Sempron 140 chip) and the system's combined power is 650w. Its being powered by a 1kw psu, but obviously it doesnt need it.
