I bought a gfx card today XFX RADEON HD 6790 on my mobo ASUS CROSSHAIR 990fx.. SMPS 600 WT.. PROCESSOR: X6 1100T (BE)..
The gfx is getting excessive hot.. is this normal? like i cant touch it.. i will post the pic:

"GPU TEMP 1" : IS it the physical temp i m experiencing when i m touching the card?
is it normal that gfx will get heated that i can lay my fingers on it not more than 5-6 secs? or some prob?

NOTE : THE card needs 2 x 6 power input frm SMPS.. my smps.. i ball 600wt.. got 1 wire.. which through "Y" divides into two 6 pin sockets.. BUT IN the gfx manual it it striclty restricted to use same wires dividing into two 6 PINS socket thorugh a "Y" .. is the reason for the gfx to get heated so much?
THANKS IN ADV

51C is fine, but that's pretty high for idle. What are your ambient and case temps at?

Also, there's really no reason to be touching your graphics card while your computer is on. In fact, don't touch anything inside your computer while it's plugged in and turned on.

From looking at the core clocks (157/400MHz), it's in a low power state; however, it's slightly above the regular 100/150 clocks that I can see from looking at another brand's BIOS.

What can you tell us about your monitor setup? dual screens? refresh rate? resolution?

If you have two high resolution screens, idling at 50C is not that bad.

What are your temps under load? A GPU is fine up to about 90-100C, 51C is a bit toasty for idle but won't hurt anything, load temps are what really matter.

I have HD 6790 gfx card.. and amd ph II x6 1100t processor.. 4gb of ram .. 1600mhz.. 990 fx mobo.. and SMPS of 600 wt..
my gfx is getting heated too much.. is it for low power supply? are they related?

|Probably not , it could be a hot room temparature ,. bad card/bad thermal paste , ot even non-suffecient case cooling/fans

What temps are we talking here ? If it was the PSU doing it i would expect it to keep going (getting hotter) until the card cut out.

While the PSU could technically cause any part of your PC to overheat, odds are it isn't or it would have burned something up by now. As for how it can happen is providing voltages outside of the specifications.

Couldn't find any good links with a quick google search, but all you need for good case flow is 1 intake fan at the front bottom of the case, and one exhaust fan at the top rear of the case. If you already have those and the case is still hot then you could upgrade to high airflow 120mm fans.

Also, you should post your temperature readings just to confirm that they actually are high.

I do want to say this... a low-quality PSU is generally going to be less efficient. That lower efficiency (besides raising your electric bill) will produce more heat inside of your case that could cause your other components to run warmer. Obviously there are better ways to tackle thermal issues than replacing your PSU, but I still feel this needed to be said.

Yes, but not directly as in: power supply A makes my card run hotter than power supply B.

The power supply supplies an electrical current to the card. The electricity is what creates heat. To state another way, when the card is under load, it uses more electricity and therefore becomes hotter. The card's heat sink and fan, and also your case's airflow work to dissipate that heat (cool air in, hot air out).

I had hoped you would have posted temps by now. This has the potential to get confusing so i will attempt to nip that in the bud.
Gpu temps up to 85 degrees are fine as far as im concerned. Any thing above that without over clocking the GPU is a cause to worry.
A quick PSU lesson. The PSU supplies the power but does not push the power to the parts , rather the parts pull power from the PSU.
If the PSU is inadequate then the parts struggle to pull the required power, much like a strong man pulling a large truck or aeroplane they get heated with the huge effort evolved with trying to pull a load that is unrealistic.
This will have the potential to make the part(GPU in this case) overheat and/or make the PSU over heat.
If this goes on for long enough or the differ ential is large enough either the PSU will die or the part will die or if you are really unlucky you will get a full system melt down and the whole system could get fried.
With a modern PSU the last possibility is a faint one with much better over currant protection these days but is still a possibility none the less.

No the PSU does not determine the operating temp of the Vid card.
