low FPS and GPU usage ( GTX 780 )

[Deleted5770650User]

 

 

 

What you posted is System Wattage. Im did not overclock so Im more than fine with 500.

Also both reviews for the Inno3D 780 claim that under load the entire system doesnt even uses 400W

Both of those pages are only showing GPU Power usage, and do not include the power draw from the rest of the system.

I had a similar issue once, and it was indeed that the PSU was too weak. This PSU was rated for 650W, and the PC supposedly only needed 520W. I replaced the PSU with a higher watt PSU and it solved the problem.

Not all power supplies are created equal. There are power supplies that can not even supply 3/4 of their rated power.

 

 

The first site has it even written on the graph. "Full System Draw"...

And like I mentioned 3 times already. Games like BF4 or FC3 would see an impact too, what they dont do...

I googled it several times and asked several people and 90% said that 500 is enough.

 

 

Why did you ask for help if you are not going to consider any of the answers you are receiving?

 

You are so focused on the watt number printed here and there that you are missing the point.

Even IF your power supply is rated for 500W if is not supplying all 500W you need a better PSU.

 

IF you still insist it is not your power supply at fault please add the manufacturer, model, and age of your PSU.

So in other games the GPU usage is 90-100%?

Strictly going by Benchmark numbers on Reviews will never show you a true value for what Your system will draw in the real world under full load like in Skyrim...For instance just did this test to show what the difference may be....

 

In the first link they Used Tessmark to do the testing on their system ...since i already have that for testing, i did a quick run....

 

System Idle = 190 Watts

Tessmark = run till GPUs are at a level temp range (10 mins) = 501 Watts

*Skyrim Full (outside) = 570 watts

 

What we see here is that a GAME can and does pull more juice then a benchmark at times. the only way to know for certain is to actually test your system under load.

 

* Skyrim = Instant power draw of 570 Watts, alt /tab less then one min into game.......too much to list , 257 mods , 2k HD , 2.8 GB VRAM in use,

 

Yes, my system is going to be totally different then your system, this is to show that a benchmark (tessmark) may not give the full load , and that Testing is the only way to know. So don't look at the Numbers , look at the difference between them, a 70 Watt difference.

You are very right here:

 

 

Ok the solution is fairly straight forward

The laws of physics are constants. Anandtech and Hard OCP correlate statistically.

They have a methodology that correlates to the design TDP.

You cannot change the laws of physics, they are constants.

 

A PSU has to be properly sized, it requires an overhead capacity or it will implode. The PSU interior temps get over 50 deg. C and the Tantalum in the capacitors breaks down and age prematurely. As those values change due to aging which is a normal process, the PSU puts out less and less.
