Which card would you suggest to mine on for under 200W power consumption?

The Nvidia GeForce GTX 750 Ti. It reportedly only uses 34W when overclocked and mining scrypt coins at 300 KHS.

Not the best power/hash ratio, but my Sapphire R9 270x cards draw about 175w and get a consistent 470Kh/s for $209.

This is the best hash/w card at the moment, next would be the Radeon R7 240.

So what's the current best combination up to 200W if you have all the other components? I could fit 4 more cards into the MB.

BEst combination would probably be the 750 ti. the BEST single card would probably 7950.

4x GTX 750ti...

Can you run them on 1 PC with ATI cards?

I've got 6 270 hashing at 4260 mh/s pulling 740 watts from the wall. Under volted from .085-.095 mv.

Best to run one type of card, either all AMD or Nvidia, mixing doesn't always work too good.


About 10x GTX 750ti can hash the same rate, but at 340 watts OC'ed.

It worked for me but i had to flash the bios.

Might be good to note that the 750 ti run at 30s watt because its bios locks it. You can get a small but signifiant but not watt efficient bump in hashing power by flashing the bios. It will then use 50-60 watts.

Google 750 ti rigs for more information. The page in question has all the numbers layed out in 3 pages articles with a 6x 750ti rig.

Hi miner765

Well, measuring as usual, from my experience:
1. Price
2. new/used card
3. Hash-power
4. watts


So the winners are:
1. R9 270X/270, approx. 185 watts. Can be still found new. Nice hash(420 on average)
2. 7790. Almost perfect: approx. 85 watts and 220 kH. Fairly cheap, can be found new if u are lucky.
3. 7770 and 7750. I'd say those are just "for fun" nowadays. 80watts and approx. 170 kH.

There is a bunch of other older cards.

Mining on any Nvidia, except reported above is a LOL as per me, in matter of particularly ur question.

Hope this helps ya.

r9 270 gets the same hash (if any worse, its like 5%) and is cheaper. Biggest advantage is it only uses 1 6 pin vs 2.

How much do 270X and 270 go for?

Amazon has rip-off prices on graphic cards.

Try http://pcpartpicker.com/ most useful thing ever if your thinking of building a PC. Look for me on there, same username!

Cheapest reliable price (from a decent brand I mean) is $180 for a MSI V305 r9 270.
For r9 270x, its around $220. So yeah if you NEED that 20 extra kh/s or so and willing to pay more for PSU's electricity bills and more money as its more expensive go ahead  ;D (don't!)

That's the cards only. Breaking it down my 270
Are pulling 98 watts each so total 588 watts. Plus I only have to run one rig. Vs 3 broads,cpu,psu,ram,etc.
six 270 are cheaper then 10 750ti. Either way I think it's awesome for 300kh/s for roughly 34 watts. It'll be interesting to see what bigger Maxwell gpu can hash.
Also I just realized I stated the incorrect hash rate for my 270.
It's 2600 MHz/s

WHAT? Hash rate is measured in kh/s, mh/s, gh/s, th/s, etc..... What is MHz? Its not even clock speed of the card as that would mean that the gpu be running at 2.6 GHz, which if true your a true Overclocker :) please explain.

Mh/s.. You should be able to figure that out. I'm sure you're smart enough..

Still confused. What lines are you referring to?

I'm referring to my typo on hash rate. That you pointed out.

Aha. Oops  ;D. No hard feelings? Just a little bit of a perfectionist/grammer Nazi  :p Hope you understand :)

My 7770 gets 210k  stock speeds and my 7790 gets 265k @ 875/1750     ;D

since when one 270 can do 700 kh/s?

ok you corrected it afterward

WTF are you talking about, 710KH/s on each 270 ?

Why do people love to post bs like this?

750Ti forsure

Read the thread. I made a typo and corrected it.  Why do people post shit about something they haven't read in full ?

So 7950 would be the best single card to use? Or R9 270/x? Again, under 200W.

Leaning toward the r9 270 (non x, 270x really exists for no purpose besides making sales on stupid people) If you can find th 7950 at a decent price, go for it. As its out that 7950 is king of hash, people are charging so much for the card, even used.

How about you write something relevant towards the OP question.

Thanks! Got the 270.

no problem   ;D glad to help.

i have 5 of this cards, the beast for it 275 khs. and the temperature is 60-68 C. You will need 4-5 fans.
