i think my brand new VIDEO CARD is broken

Mr GRiM said:

The PSU you suggested to them was actually a better one for you then the one they told you to get, the one they told you to get has 6x12 Volt rails so you divide the 1000 Watts into 6 and that gives about 160 watts per 12 V Rail, where as the 700 Watt you originally wanted only had 2x12 Volt Rails giving you 350 Watts for each 12 Volt Rail, looking at the specs they give you on their site it states you get 30 Amps on each 12v rail.


This is from the product website.

So they told you your Graphics Cards weren't connected to a 12v rail, if that's true I would very worried, when you removed your card yesterday was there a 6 pin power connector going to each of the cards?

no it was just seated on my mother board...


i think i just remembered what the techguy from pchub said..

"there aint no 6pin power connector that's why you wont need the *other* PSU"

i think he was telling me that my vid cards would work even without those pins or something... i can't remember since i dont really understand these "pins" and "rails"

Can you tell me the exact model Graphics card your running, I don't know of any high end cards that don't require at least one 6pin power connector, even my 8600 and 9600 GT needed them and my GTX260 needs 2 6pin connectors.

Also have you done a WEI test on that rig yet and what was the score you got?

my box tells me that it's a "Palit GeForce 9800GT 1gb 1024MB/256-bit/GDDR3 Dual-link DVI/HDI"

my WEI score is 5.5 because of my RAM.. the others are around 6.+++ can't remember.. I'm still rendering in my new rig so i cant use it at the moment.. it may take a while

Oh dear. It sounds as though you were very lucky though. In some cases, omitting to connect an auxilliary power connector to a graphics card that requires one can cause problems such as failure to operate under load. It can even cause motherboard failure in severe cases, especially if it tries to draw too much power via the PCI Express slot. Even mine requires it, although I have used the adapter that came with it to connect it to my PSU via 2 HDD molex connectors (my PSU doesn't have a dedicated 6-pin connector).

my rig still works okay now... but can't detect the other video card..*it detected my two cards before i restarted my computer*

Notice the highlighted supplementary power connector requirements. Note that this is per card. If you have more than one installed, then your PSU has to have sufficient connectors available.

If the card has the 6 pin socket then it will definately require it and from this article I just found it states.

This video card requires the installation of one 6-pin auxiliary power connector. The product comes with the necessary adaptor for you to convert a standard peripheral power plug into a 6-pin power plug if your power supply doesn’t provide one of them or if you are installing two cards in SLI and your power supply has only one auxiliary power cable for video cards.

If they are telling you otherwise then I would take your computer elsewhere as they clearly have no idea what they are doing.

If you have the 6 pin connectors on PSU then I would suggest you connect them.

Looking at the specs on your PSU it states "3x 8 pin PCI-E connectors (6+2pin)" so there is no reason why they should not have been connected.

this is what im using.. sorry i forgot to put "green" on the name

Well if that's the ones you have then it looks like it doesn't need them so your problem must be something else, that card also has a lower power requirement so the PSU probably isn't the problem either, now I am thinking its the OS that might be your problem.

I think you should try x64 because it might be a memory sharing issue.
