Planning to build another rig in the near future and I'll probably run 3-5830's + 5870.
Everything else will be minimal except psu. http://www.newegg.com/Product/Product.aspx?Item=N82E16817152044
Seems like this is the cheapest 80 gold 1000w. Opinions would be greatly appreciated, thanks!

I don't feel qualified to rate PSUs, so I leave it to the experts. HardOCP is typically considered a reputable review source and they say:

http://www.hardocp.com/article/2011/02/23/raidmax_rx1000ae_1000w_power_supply_review/9

That it is a pass (pass in this case actually means really good and reliable, not the best necessarily but it should handle what it says it will handle).

That's actually a pretty good price for a PSU of that quality and size so I will save you from my usual speech about spending too much money on an oversized PSU.

enjoy!

Yea was browsing for a new psu since my current one is a Corsair TX850 but only running 3 5870's. Next one will run 4 cards so a 1k watt should be just about right.

Well I had this debate with someone the other day, but I'm currently running 4 5870s (@ 430MHash) on a Seasonic X750. My wall meter reads the power draw at about 783Watts to the system, so I'm slightly overloading it (it is fine but I suppose for the very long term this might not be the best idea). So an 850 should be adequate assuming you have a mining rig similar to mine.

If you are really super squeamish about running a PSU near its capacity (which seems weird to me, people don't buy 3GHz CPUs then downclock them heh) then getting a gold class PSU isn't actually that bad an idea, when running huge loads the efficiency actually begins to actually save you money, depending on your power rates.

Well I don't dare to be in your shoes. Example: Current rig, 3-5870's 850w Corsair. I want to play it safe and have headroom so I don't shorten the life of my psu too much. Plus the PSU in question is really good pricing for a 1k watt so why not  Tongue

But that link of the review you put up OCP did say they don't feel the rating is right. Guess maybe they don't feel its up to gold specs, even if it falls under 80 plus silver, that is still super cheap.

What are you running your memory clock at?

Mining at https://www.bitcoins.lc/ @ ~1,2GHash/s

That's fair, Lots of people don't feel comfortable for some reason, and that is a steal even if it's not the best unit in the world. It will definitely power you through hard times heh.

I run my memory @ 300Mhz on all cards. Less power, less heat, good times.

Yea underclocking memory is a must.  My 3-5870 setup right now has main 325-330 mem clock on all of them and I use this as my everyday computer lol.

My main rig is a 3x5870 setup and I do the same as you heh. Although I will have to adjust the memory back up manually because my friends are getting annoyed with me for not gaming with them (want to keep all my gpu power hashing!)

A nice PSU, though you might could get better amperage on some nicer ones.
"+3.3V@24A, +5V@30A, +12V1@36A, +12V2@36A, +12V3@36A, +12V4@36A, -12V@0.5A, 5VSB@3.0A"

Still, 36A is nothing to scoff at and definitely nicer than lesser PSUs, go for it.

I personally like the Corsairs 80gold psu's http://www.newegg.com/Product/Product.aspx?Item=N82E16817139014
THough this model does have a shared 12v rail.

Yea but I'm being a cheapo here. Only want what is needed for my setup and that's it. Thouse Corsair 80gold is nice though but pricey.

True, true, I can be a bit of an over-spender at times. That one you have picked out will work just great for what you want to do.
