Hmm… odd that the CoolerMaster is marketed as single rail then. But I found it on the American website and see the same specs you found, so I’ll stay away from that.

Actually, the Seasonic is cheaper as well, so it’s no problem.

By the way, by pure luck, my choice of PSU was the XFX ProSeries Black Edition - 1250W. Only thing unlucky is that the Seasonic would, again, have been cheaper… I’ll order one of those when I get money back for the ASUS 7990 that I’m going to send back to the shop tomorrow. That thing is just too hot. I don’t think there is any way it would ever run cool enough without water cooling or something equally radical.

luckily the xfx is a the same psu as seasonic, just with a shittier fan.
still not a bad choise:)

Woke up today to a smell of really well burned plastic, i was like NOOOOO!

Went down to the basement and was like a narcotics dog, sniffed all the cards but couldnt locate the source.
Checked my monitoring app to see that my 4x7970 rig was down, so i started investigating it over and over. everything seemed fine and i restarted it back up (phu, it wasnt one of the 7970 cards).

I then realized that that burning smell came from the ONE bad PSU i got (apart from the Enermax), A one month old Corsair TX750,
that construction consist of a mini atx mobo with amd LOW end processor and 1ram+128gb ssd and two 280X.
Sooo powerwize i should be fine! Apparently not…

Will see if the burned smell goes away. but im ordering a Seasonix X1250 as we speak cause that Corsair gotta go!

Ouch man… That woulda been a short period of panic followed by somewhat relief.

svennand

had to move stuff around and reuse my Enermax 1500W that had been collecting dust. So now that one runs 2x 280X and the shitty Corsair one will be running 1x7970 instead while i wait for replacement PSU.

Was gonna order me more 280X cards today, but my god the marked is completely sold out of ALL 280X disregarding brand/shop! amazing :-\

TheRedViper

if the PSU was the source of the smell(got fried) how did you manage to turn it back on?
or is it that it just overheated and melted some plastic without actually damaging its board/components?

from the moment i started mining i have this anxiety and fear of burning my rig :-\ . hopefully that day wont come.

Most likely overheat and some plastic that touches something that its not going to.
The rig works fine, even with 280X it still kept mining without issue which is why i though it was the other rig that was the reason. since the smelly one was mining away…
Seems that its just when the psu gets pushed that it smells burned, think im gonna wait for a replacement and then complain at my local shop on the corsair.

Everything is up and running again at least: [url=http://50.87.190.116/monitoring/]http://50.87.190.116/monitoring/[/url]

Appart from missing about 6 280X cards come one mailservice BRING EM TO ME! ;D

EDIT:
Oh and yeah, fire is scary stuff, which is why i have two smokedetectors in the basement along with one in each floor and one on every bedroom all wired up to a system that distributes to all alarms including an separate sirene and SMS going out to several key people… I dont leave anything to chanse, also has a fire extinguiser next to the miner room ;D

[color=red][b]Watch out! According to your monitoring, “FUZZYPC” is running at 98 and 101C!![/b][/color]

Geez! It really sounds like those Seasonic (and XFX versions of the same) 1250W are the only way to go.

I’m happy to hear that it wasn’t your new rig that gave off the smell!

I ended up ordering one of those Seasonic yesterday as well. It’s too bad that the PC I use daily is only able to have one gpu running when I’m not home, so it’s getting upgraded tomorrow ;)

Oh, very nice remote monitoring! Teach me how, master!? :)
I’ll need a static IP and some port forwarding, I guess, but apart from that… what is the software you are using for this? Or did you create it yourself? Or is it part of CGminer somehow?

The 7990 usually run around 102degrees… under 100 i call cool ;D, cgminer haven’t crashed once! pretty damn impressive!
I only buy seasonic from now on, between me and nutnuts experience we have tried and failed quite some PSUÂ´s, We both use Seasonic for all our rigs and non of them have ever quited! with both of us running 4x gpu rigs thats pretty damn impressive!

btw regarding the monitoring thing, its pretty easy to set up, but you need to get a webhost or set up on on your own machine:

I could live without that monitoring thing, can check it from anywhere as long as i have internet connection 8)

OMG - [b]now you’re scaring me[/b] :p I’ve got 1x Corsair HX850 Pro Gold powering 3x7950 currently pulling 580W@Wall + 1x Corsair RM750 Gold powering 2xR9 280X pulling 470W@Wall. I hope I wont be smelling anything soon here :o

Im guessing you under volt since you you get that power consumption on wall side?, 2x 280X at 470w including 150w system consumption??, you shouldn’t be worried.

I dont under volt so my 280X pull close to 300w each. still should be more then enough given that the estimate from a PSU is on the dc side, meaning with a 80% effective psu you should be able to draw 900w on a 750w psu

Ok ty =) I was just worried b/c I got the PSU’s from the same brand width identical PSU watts, running the same cards

yes I run the 280X @ 1000engine / 1400memory @ 1.07v each. Running with no hickups since saturday at about 1370kh/s total. Idle power consuption is around 105w. Undervolting saves me about 50+ watts per card, compared to stock settings.

I have an Akasa Venom Power 1000w PSU,

Could this handle 3x Vapor-x R9 280X ?

If your gonna go max hashrate and not undervolt etc i would be sceptical.
Nutnut runs a 3x 280X Asus matrix platinum on a rig with Seasonic X1050, the Seasonic does work a bit with cooling the PSU
Since its seasonic he doesnt worry that much=P,

those cards use around 290w so thats roughly 900w, then the system use about 150w (normal), so he is on 1050. but we know seasonic has some overhead here=P

Using an Akasa Venom Power 1000w however i can not guarantee anything… im not that familiar with it
