Default Re: GeForce 6800 power supply questions

OK kahloq thanks for the tip,
I will try at home later with new cabling

Is it easy to differ which is the 1st and 2nd power connector of the card ?

Or are they marked with numbers ?!

Unhappy Re: GeForce 6800 power supply questions

OK - i took the powerconnector from the DVDrom (the line where my 3 scsi drives are on) and connected it to the "secondary" molex on the 6800.

I re-checked in windows, but the +12V still is around 11.67-11.61 in windoze and "jumps" from 11.61 to 11.55 down to 11.49 (in large areas) when i played doom3.

Sure, it could be that those crashes were card/bios related ... and the Voltage is ok, as long as it does not reach 11.4V or below...

But i read another thread on the EVGA forum where a user with a 550W PSU had problems too on the +12V with 11.6 or below volts, and a new PSU helped him.

I had a FX5950 before, really can`t believe that my good PSU should be the bad part here

Unfortunetly, some of the PSU's out there dont hold their current well under load. If you weren't aware, the 6800 series cards draw more power then the 5950's. So what worked good before may not work 100% well now. I checked the link you provided in an earlier post. Although I can't read german, the stats looked ok. I cannot though find any information on that PSU: (TSP 450 P5 Ultra Silent - 450 Watt - Triple ) other then one or two sites that all are in german. I tried a search and came up empty. This concerns me some as a PSU maker that is well known is going to have multiple places where it would show up and reviews of some kind.

A few things to attempt. A)Is your motherboard bios up to date? B)Have you attempted to update the bios on the Gainward card? Some ppl have reported faulty bioses on some european cards like the Gainwards and had to use another vendors bios to fix the problems. C) Is there anything you can disconnect to check to see if it affects the voltages?
However, since what your reporting is low voltages, it may in fact be the PSU you got. Although its pretty and all, I especailly like the blue led fans, it may not be carrying the voltages well and at opperating temps(40c) is not producing the current its listed at in the specs. Most PSU makers list their specs off of a temp reading of 25c. So in reality, you may be experiencing more like 16a on the +12 at 40c. Your voltages are real low and that in my oppinion is an indication of a lower output on the PSU.
When not gaming, your +12 voltages should not be that low(11.6). As a side note, my OCZ 520 always stays between 12.342 and 12.403 even while gaming.

Is your PSU adjustable at all? Most PSU's aren't. If it is, it is most likely adjsutable inside the box...meaning you got to take the cover off the PSU and mess with something inside it. OCZ fortunetly makes it real easy and has the adjustment locations located on the back of the PSU.

If you decide to flash the bios on the gainward, make sure you make a backup first of the original.

Question Re: GeForce 6800 power supply questions

Well, TSP is a good brand normally...

I dont have the newest Bios on my mainboard, because the first revision i am running, is the best for overclocking.

A friend told me perhaps the voltages which are shown could be "false" or i should not 100% trust them, he advised me to use a multimeter to measure them correctly.

But you are fully right, the 11.67V on normal windows usage is a bit strange !

I already was running the XFX ultra Bios for my Gainward because the original Gainward bios was really crappy.

I now have the newest EVGA ultra Rev04 on the card, will see if that runs ok too...

I will try the tip with removing stuff to look what uses the voltages.

I perhaps could try feeding the card with a seperate PSU to look if the voltage still remains that low.

I saw the OCZ has 2 special power connectors for VGA and HDD, do you use both of them for the 6800 card , and the normal for HDDs and other stuff ?

What are the specs of the "other" psu you mentioned you may try and power the vid card with?

Default Re: GeForce 6800 power supply questions

Its a "Noiseblocker" PSU

with 430W
+3.3 - 28A
+5 - 36A
+12 - 20A

I could "shorten" it so that it runs as soon as power is connected, and just have the card powered with this one.

I am running a SFF PC too (SHUTTLE SN45G) with a 250W Silent-X PSU and a PNY 6800GT@Ultra, and there the +12V is very good (dunno exact how much now)...

Yes. Both of the 2 special power connectors are running to my 6800 Ultra and the normal molex lines power the ata HDD's and opticals and fans. The other 2 HDD's I have are sata and run off the seperate sata power line.

Have you tried using that 430 watt you listed above in your system with the scsi and ultra? I dont mean as a 2nd psu by as the primary?

Actually, the 5950 uses more power under load than even a 6800 ultra. Source: http://www.xbitlabs.com/articles/vid...v-power_9.html

I didnt specify under load conditions regarding the comparison of 5950 and 6800 ultra. AS your own link showed....at idle...the 6800Ultra draws more power then the 5950 regardless of clock speeds. Under load...yes the 5950 takes slightly more...but there is more a difference between the cards at idle then at load and that is why I said the 6800 series use more power.

This is a quote from that article:
Quote:
Still, it is not perfect. New graphics cards on NVIDIA’s GPUs are misbalanced as concerns power consumption. The most powerful cards put a heavy burden on the +12v power rail, and this is the real reason – not the total power consumption of the device! – why you must ensure your PSU can stand such a strain before purchasing the card.
