GTX 260 Fail. A lot.

[DogMeat]

Bang on the money, sulky. :yahoo:

The main PSU is 19A @ 12v, the aux is 20A @ 12v and the card's spec from the manufacturer's site sez:

Minimum 400W or greater system power supply (with 12V current rating of 25A)

Thanks, matey.  :thumbsup:

More expense.

(T-Bag - knew Catalyst drivers were for ATI...)

the Omega drivers no longer gets updated, and the latest is over a year old..

Oh :doh:. I haven't updated my graphics drivers since shortly after I bought my card and that was when the 4870s first came out. Didn't use the omegas then because it required special drivers because it was a new series.

It's a shame. The Omega drivers were always much more stable and better performing for me.

actually the power requirements for a GTX260 isnt as bad as one might think, i havent seen a GTX260 pull more then 180watt load.. simple math 180w/12v = 15 amps (even with nvidia numbers 270 watt/12v = 22.5amps you arent near the claimed 40a).. so in theory the aux psu you have should be sufficient.. but with capacitor aging, and most likely crap quality its probably undervolting, rippling like crazy causing a unstable..

and the fact running sli psu setups is risky.. might even be the cause eventho both psu's are stable and powerful enough

Tho i wouldnt rule out other bugs might be causing the bsod too..

id recommend first trying to card out in a different machine, or borrowing a larger psu and testing your rig with it

trust me 600 watt and 40 amp rail is the way to go...
been overclocker for many years now and i have pushed theese cards to limit, so i know what they want

Initially, I used the card with the original PSU and the crashes came about 10 mins into a game.  With the aux PSU, and most external USB peripherals unplugged, it lasts 20 mins or more (CS:S for example)

:withstupid:

If the card fails in another PC the problem is found. If not, the search continues

OT:
hmm ofc, so my two gtx 260 216 running 890/1250  pulling around 170watt load is on crack ofc..


but get the puter tried out with a quality PSU, and see if it correct your props.. if it does it might be time to invest a small amount of cash in a proper psu..

Corsair/Seasonic recommended.. some Hiper are qual too, but after the swap to Channel well manufaturer they arent as great..

I full recommend both Hiper and Corsair. PSUs too.

I used to like Hiper too, but after they chose channel well, they quality dropped a fair bit, CW has some ripple issues..

Corsair / Seasonic is the same thing just diff stickers

Anyways a tiny bit off topic as problem still isnt known if its the psu

they should push out much more than 170 watts mate.
2 x 4870x2 @ max speed on a qx9650 @ 4.2 ghz ln2 pulls our arround 1300 watt @ 60 amp on 2 x 12 volt rails

mine 2 x GTX 295 are pulling arround 200 watt in idle 600 in heavy load. the best way of meshuring theese specs is to pull out your old school 250 volt and put it on your 250 volt plug it will tell you exsacly how much you use.

that way you can determine how much your drives cpu and gpu is pulling at load..
you mobo and drives are arround 150 maybe 200 depends on how many drives you got.

if you have a newer psu then it can tell you how much its feeding to your general hardware. rest is going straigt to your gfx..

if your gfx is pulling only 170 watt then how come your feeding it with 6 x 12volt rails??

this isnt really the place for this.. but..

that makes no sense..

1300watts / 60 amps = 21.6volts.. i wonder where they are getting that voltage and why the kit isnt dead yet
where it should be 12v*60a = 720w max

1. i dont really know what you are on about, if i wanna measure how much my rig is pulling from the power plug, i wouldnt really be measuring in voltage as the voltage in the plug should be 230 ( where i live) at all times. now wattage is what you wanna measure.

now.. i dont really know what your talking about with the 3x12 rails.. in theory you actually supplying each card with 5 (1 by the pci-e port, 2 12v rails pr connector) the pci-e can only supply up to a max of 150w max in peaks, rest is supplied with connectors, the reason for more then 1 connector is purely stability as most gfx cards utilise deferred phase modulation for more stable power


but again this isnt the place for this, as this has nothing to do with DogMeats problem

kreg.
what dossent make sence and what does. i have seen the numbers and i know it.

i dont know where your specs are from but fair. think you should come by some day and il show you how to play with nitrogen and voltages

subject: recomended psu for GFX 260Ã,´s

Hi Josh
i have this issue with people complaining about required powersupplys to GTX 260 and 280 seres.

I have been writhing on several forums where people containusly want to be right.

my recomendations are:
Corsair.
600 watt 40 amp rails.

as a leading expert on nVidia pruducts you should know it..
what would you recomend?

Best regards
Hamzalija Meco

hi meco..

hehe you should know it as good as myself.
on topic:
well depends realy if you overclock or not.

i would say like many others:

For the 280 GTX producers recommend the use of power unit with not less than 550 W, with not less than 40 a. Along the +12 v line , for single video card geForce GTX 260 the use of 500 W power unit is enough ( at least 35 a along the +12v line) .

so your recomendation on a 600 watt is a bit better, and even if you are running more than 2 drives + 1 optical drive.

btw, did you get my package???

Regards.
Josh XXXXX

[sulky_uk]

some weird and wonderful replies
 
 
anyhow as long as the new PSU has the minimum for the gtx 260 in amps on the 12v rails Plus i would say another 10 or 15 for good measure than that would be enough
 
also the main and aux psu's dont know what each other are doing, i would suggest that when 1 lowers it amps the other cant compensate because the regulators are in differant boxes , wheras on multi rail system there is regulation between the rails to ensure the ampage/voltage requirement is met
