Title: Another power supply + ram question Post by: Charloz24 on January 25, 2014, 01:16:08 AM Hi again, I was wondering whats the best power supply for the price the make a mining rig of 3X 280x.
ALso, is 4gb of ram is enough for it also? Already have that for 2X 280x, so was wondering if it still enough if I add a card. TIA Title: Re: Another power supply + ram question Post by: zackclark70 on January 25, 2014, 01:17:49 AM Hi again, I was wondering whats the best power supply for the price the make a mining rig of 3X 280x.

TIA the corsair hx and ax series PSU are awesome :) 4gb should be fine unless your running reaper as your mining software Title: Re: Another power supply + ram question Post by: Charloz24 on January 25, 2014, 01:57:45 AM Ok thanks but how much watt the power supply?
Title: Re: Another power supply + ram question Post by: zackclark70 on January 25, 2014, 02:13:44 AM Ok thanks but how much watt the power supply? how far do you plan on overclocking the cards ? Title: Re: Another power supply + ram question Post by: Charloz24 on January 25, 2014, 03:18:57 AM no overclocking
Title: Re: Another power supply + ram question Post by: zackclark70 on January 25, 2014, 03:53:15 AM as long as its not a high wattage cpu and not tones of other junk running of the PSU an AX860 should work well
( I am running 3x 7950 gfx cards overclocked/ undervolted on 1 X HX 750 and its only pulling 700w from the wall ) I don't think the gpu you have are that much more power hungry and your not planning to overclock please don't just take my word for it do some research on what the total wattage of your system is then add at least 10% to that and it will give you some idea on what you need if you can tell me the complete component list I will be able to tell you more but going on what you have said an ax860 should be fine there are plenty of cheap brand psu out there but don't be tempted by them as they are junk I personally like corsair as I have used them a lot and never had an issue + have a good resale value Title: Re: Another power supply + ram question Post by: AtlantisPlatform on January 25, 2014, 04:31:35 AM Hi again, I was wondering whats the best power supply for the price the make a mining rig of 3X 280x.

TIA I have 3 Asus 280x cards on one machine, I have a Seasonic x-1050 psu, 4 gb ram, runs awesome and stable. Wattage at the wall is 925 watts using kill-a-watt. Cards are running on stock voltages. They are running cool and stable at 720 k/h each Title: Re: Another power supply + ram question Post by: zackclark70 on January 25, 2014, 05:07:54 AM Hi again, I was wondering whats the best power supply for the price the make a mining rig of 3X 280x.

Never tried 1 GB as 2 GB are necessary for 64 bit.
Just wanted to point it out. :p Title: Re: Another power supply + ram question Post by: atp1916 on January 25, 2014, 12:32:48 PM https://bitcointalk.org/index.php?topic=427347.msg4666835#msg4666835
The Corsair units are overpriced. You pay extra for the name. LEPA (Enermax brand) and XFX CoreEd (Seasonic oem) are units with very comparable build quality. OP, i would suggest you put all 4 of those PSUs listed on auto-notify and grab the next one that pops up. Title: Re: Another power supply + ram question Post by: TehLuNaTiC on January 26, 2014, 10:55:21 PM a good quality 850w i think is ok for 3 x 280x
as for memory ill stick with 8gb Title: Re: Another power supply + ram question Post by: cisahasa on January 26, 2014, 11:00:47 PM tested with 2gb mem/ 2x280x
