My new 1500W can not handle my computer

[AdamDBurns]

Boy are you only in overkill mode i wish i had that kind of money😉

 

[Di7]

first make sure that the video cards are being fed by the larger +12v rails, that would be 3 and 4.
see if that makes a difference

Then, try running just one video card for a while and see how that goes.
pull one card out then benchtest for 24 hours, remove that one, replace with the other. retest for another 24. If you get no failures, that points to three possibilties

1. second pci slot is possibly bad - a remote possibility

2. your power supply just cant handle the load on a particular rail - switch to a single rail type.

3. possible overheating in a particular area or chip that only happens when both cards are installed. two cards of this size will generate HUGE amounts of heat
and the PSU also puts out huge amounts as well. try running with the case open maybe put a fan blowing in cool air. retest.


BTW - is your PSU , certified for this configuration?

check here- http://game.amd.com/us-en/crossfirex_components.aspx?p=3#ATI%20Radeon™%20HD%204870%20X2

- The computer did not faces this problem with previous PSU (if faced a different problem).

- The new 1500w which I have is 2007 model but they said, in the box, it supports nVidai SLI and ALL Multi-Core GPU technology. In the manual they wrote: .....Toughpower 1500W is able to support NVIDIA SLI & ATI Crossfire technology and multiple high end graphics cards.

I could not find it in the list.

Next time just throw your money into a prebuilt system please. You clearly don't know how a PC works.

I'm learning....

You spent $1000 on an i7 965 just so you could OC it to 3.33ghz?!? What is wrong with you?!!!!!!!?

xthekidx, don't push me.. I'm going to overcolck it to 3.8 / 4.2 ..but not right now..
First I want to end the power problem..
I'm working slowly..

By the way 3.33Ghz is the default.. I did not overclock the CPU yet..

 

[edwilson]

there is a big difference between supporting a multi card configuration and being certified / tested for a particular config and/or build. I would contact ATI and TT to see if what you are trying to do has been done and or tested by either of them. perhaps they can provide us with some usefull info. I am sure they both have forums like this one, scour them for info.

The PSU is certified by Nvidia SLI, check this page:

It has all information about my PSU.

I have seen several posts where people were having similar problems with rebooting on the i7 systems.
I believe these problems were fixed by most people by updating their motherboards bios to the latest versions.

Make sure your boards bios are up to date, then do a stability test on the system with no overclocking.

Sounds like a problem with your motherboard or your overclock to me.

 

[xthekidx]

By the way 3.33Ghz is the default.. I did not overclock the CPU yet..

3.2ghz is default. You have turbo mode enabled.

 

[cjl]

3.2ghz is default. You have turbo mode enabled.

Yeah, but I would still consider that to be default, considering that the turbo mode setting is enabled on all boards by default.

 

[Di7]

3.2ghz is default. You have turbo mode enabled.

OLD --> You are right, should I try the extreme mode with the regular intel fan?

ADDITIONAL:
OH Wait.. That was not true.. I change the setting to standard mode and it is the same 3.33Ghz.. I guess it is the default for one of the cores (just guessing).

Man, you are playing with some serious power bud!!! You're PC takes so long to shut down because power is still running through it for 10mins!!! DAYUM 😵

Honestly, i would try another PSU (1000w should be more than enough). You over estimated the ammount of power your computer can handle. I can almost guarantee you an 850W PSU will power your PC with no problem!!

Dude, i hope you understand how much power you are generating in one spot with that hardware.

I tried 950w and it was not enough for two 4870X2..

I upgraded to 1200w and few days later I smell something burning in the room, it was IT!!

Then I upgraded to 1500w and this problem appeared!!

Don't you think that there may be a problem with the Motherboard?

I faced over heat problem with the north bridge with the old 1200w..
(the red led was flashing or at least ON which means it was over 80C during a heavy load.)

I thank all for commenting, I'll replace the motherboard tomorrow and see..

If you still have any suggestions please let me know.

 

[Kill@dor]

Well try turning your computer on again after an hour or so and see if it posts. If it doesn't boot to your desktop then you have a problem...most likely you fried something, even your PSU. If it posts, i would recommend getting at least a 1000w since you claim a 950w is not enough.

Also, one thing i noticed is you have s**** load of hard drives...for what reason i don't know. Are you using IDE or just all SATA? Running both can sometimes cause system instability. Make sure the HD's outside of the case are off...unplug the other 2 SATA's for now and leave the 2TB HD's on and inside the case. Then try turning it on...

Here is a link to the official ATI list of 4870X2 certified power supplies.
http://game.amd.com/us-en/crossfirex_components.aspx?p=3#ATI Radeon™ HD 4870 X2

Yours is not on the list, but some lower powered variants are.

Unless it is defective(which I doubt), I don't think the psu is the source of your problem.

 

[Di7]

Hey..

Kill@dor, If I turn the computer off completely the LEDs stops in about 10 seconds.

*I was using IDE but I removed it..

**I'm using lots of SATA hard drive with RAID to achieve better performance.

***I don't think I'm downgrading to 1000w... 1500w is sexy and I loved it. (I hope I can fix the problem without losing it🙁).

Your PC shouldn't have an electrical charge...that would be a bad thing. Your house is grounded right? I doubt you need that extra peice of the MB, its probably a tool that is included to help installing something. Don't worry about it, its not the cause of your problem.

I have electrical shocks with my Macbook Pro all the time, I feel it.. sometimes I jump because of it. (lite shocks I mean).

I know.. it is not in the list.. but they said it support quad GPUs, see here:
http://www.thermaltake.com/product/Power/ToughPower/w0171/w0171.asp

In fact, two days ago I left my computer on with GTA IV running at the highest graphics level for 8 hours with no problems at all. (QuadfireX was ON, and the fans were at their best).

Looks like i was wrong about 850W working with 2 of those cards. But i bet you if i tried it i could get it to work. I used an 8800GT, Q6600 and 2 500GB HD's in RAID and an external 150GB HD on an Intel board OC'd with a small 400W PSU with extra's if that tells you anything.

Macbook and desktop cannot be compared in power... That shock you get is just static (normal)...desktop (even a 400W PSU can fry your brain) PC's obviously use more.

If i were you, i would leave the 6TB's you have in RAID for now, take out all the other HD's and take out one of your graphics cards (for testing only). Plug one thing at a time until it gets unstable again!!

Man, if this doesn't work for you i really don't know how to help. I'm a newbie too, but it doesn't take rocket science to figure out you are using a ton of power. Can you pay my light bill please?! LOL! Again, you need another PSU because it is generating far too much power!!

 

[EQPlayer]

Your PSU is total overkill. I'm running dual 4870x2's on a 1000W Corsair, and your extra HDD's don't use much power at all compared to graphics cards.

 

[Tech-Boy]

You have a real nice computer the kind of computer that keeps most of use awake at night!

I would take one 4870x2 out as someone suggested then make sure you have the most up to date bios version for your motherboard. Then see if your problem remains.

Good luck!

 

[edwilson]

op can we get an update?.. still having issues, did you try anything we suggested?

 

[Kill@dor]

Just discussing PSU's on another thread. You probably need to find a single rail PSU instead of a multi rail!! But that would mean sacrificing modular cabling...

There are pro's and con's to each of the different styles of PSU's. I have been a power supply designer for more years than I want to think about. One is not better than the other, they just have different design philosopies. It is just like graphic cards, some people swear by ATI and some swear by nVidia. Whether using a single rail or multi rail has nothing to do with Di7 getting shocked. He has some current leakage path in his system that is really hard to detect without looking at his system. I do think the leakage is happening in the PSU, that is where all of the large caps are that can hold a charge and would take a while to drain down.

 

[pajama]

Modern PSUs are cabled in a way that won't cause excessive load on one string of cable alone.
The old ATX12V spec. with 240VA limit on 12V rail is pure nonsense which is why it's removed from latest v2.2 spec. New PSUs you find on market today should have one large single 12V rail or two for those >850W PSUs needing two 12V circuitry.

There has NEVER been a single advantage of multi-rail PSU as they're all virtual rails with an artificial OCP placed on them. If you want to cut yourself then touch the connectors while your computer is running go ahead. 😉

btw, the rest of this thread provided me with laughable contents. Thanks for the entertainment.

Wusy you have some really good points, but never say NEVER. You do get lower emissions with multi rails, that may not seem important unless you are trying to get the CE Mark for your product.

Since we have someone here that is in the industry, perhaps you could clarify for us the various certifications / requirements, and the various power classes / requirements. For instance, what certification requires 18A max output on a 12VDC rail? I'm curious personally, as I have a Seasonic M12 700W, the label states four +12v outputs @ 18A per, but there are only two landing pads for the +12V leads...

Croc, I am not what you would call "in the industry". I am just a design engineer that helps design power supplies. I spend most of my time at test labs. Here is what I can tell you about certifications:
UL/CSA (US and Canada) - mainly test for safety (shock hazard, leakage current, etc). They test and examine all components attached to the mains.
CE Mark (All countries in the European Economic Community) - They also check for safety, but they also look at (these are my fields of expertise) 1. Radiated emissions, 2. Conducted Emission, 3. ESD Immunity, 4. Radiated Immunity, 5. Conducted Immunity, 6. Magnetic Field Susceptability.
FCC (US) - Similar to testing that is done for the CE Mark

There are other Certifications but these are the main ones used around the world. The standards that are used for the testing are many and are determined by the wattage of the supply. That is one reason that 700 watt and above PSU's are so much more expensive (they fall under more stringent standards for Emissions, etc). I hope this helps. If you would like more info just send me an E-mail. I am sure most people on the forum would get put to sleep reading about EMI Testing. 😴 Only the nerdiest of the nerds gets involved with EMI/RFI.
