I have a power supply unit that meets the 500w , I had to get a 6pin to 8pin adapter to get the required 2x8pin, everything seems fine and have not had any issues. Question is am I getting enough power to maximise the performance of the card? Do I need to upgrade the PSU to one that has 2x8pin setup.

What power supply do you have?

My box says minimum power supply of 500 watts, so it should work fine. Single rail would be better, but don't expect it to last a real long time as it will be
running pretty strong most of the time and will result in more heat buildup. But it is OK.

You have to tell us what 500w you're using. If it's quality you should be fine.

Sorry guys I had this all in the original post but for some reason I lost all my text when I accidentally closed the browser before actually posting it! LOL This is the PSU I have LC Power LC6650GP3 (I had this as a link in the OP but I think it got deleted and that is why it was not there) Well While I am at it: SYSTEM: CPU: AMD FX 6300 Six Core GPU: EVGA GeForce GTX 1070 FTW GAMING ACX 3.0 MOBO: AsRock 990FX Extreme 3 8A RAM: 8GB Corsair DDR3 /CMZ4GX3MA1600C9 PSU: LC Power LC6650GP3 OS: Windows 10 64bit AUDIO VISUAL: Monitors: 3X 21.5" - 1X Samsung SMBX 2231 + 2X , 1080p, 5760x1080 60Hz Audio: Onboard 7.1 Realtek ALC892 Audio Codec Speakers: Altec Lansing ACS56

Welcome to the forums. You should be good to go as long as you're not experiencing any boot, shutdown, freezing or gameplay (low FPS, black screen, studdering) problems that can be associated with an insufficient PSU. An EVGA GTX 1070 FTW is a 215 watt card (~ 17.9 Amps @ +12V)..Of which it can get 75 watts (~ 6.25 Amps @ +12V) from the PCIe slot itself, leaving the remainder of 140 watts (~ 11.6 Amps @ +12V) to be supplied by the Supplemental Power Connectors (6+2-pin or 8-pin). An 8-pin (or 6+2-pin) connector is rated for 150 watts (~ 12.5 Amps @ +12V) and is programmed into the card's VBIOS not to exceed that current draw as specified by the industry standard PCI-SIG specifications. EVGA and other vendors can and often do exceed the minimum power requirements of their cards by adding extra 6-pin/8-pin connectors to promote overclocking/stability, for example a 225W card (75W from the PCIe slot and 150W from one 8-pin connector) might come with two 8-pin connectors (75W from the PCIe slot and 300W from two 8-pin connectors, or a combination of 6-pin/8-pin Supplemental Power Connectors, aka PEG Connectors) to feed the card extra wattage/amperage. Amps (horsepower) on the +12V supply is the most critical factor..The wattage is calculated at +12 volts and can be converted using a Watts-to-Amps Calculator. Since your LC6650GP3 V2.3 - GREEN POWER PSU supplies 27A on 12V_2 which supplies over and above the additional ~ 11.6 Amps @ +12V of supplemental power for your GTX 1070 FTW, there should be no problemo. However, +12V_2 on a two-rail PSU such as yours also normally supplies all the other components in your system and +12V_1 usually supplies only the motherboard and CPU power. You can use this PSU Calculator to estimate your overall system wattage requirement. Long story short = You're okay if you're not having problems and your benchmarks are keeping up with the Jones's.

Now that you mention it I do feel I have a bit of a lower FPS (than I was expecting with this card) and occasionally a bit of a stutter. This was the main reason for starting this thread. I run a racing sim "Assetto Corsa" the in_game benchmark I get a solid 63 FPS, However if I race with the same number of cars, track and graphics settings (max) as the benchmark I am only getting 40- to 45 FPS. I have tried to lower the graphics settings and it does not seem to help much with the FPS.

With that power supply you should be just fine. Your low fps in Assetto Corsa is due to your cpu.

Thanks @Sajin. Ah! Bugger!  that's not what I wanted to hear! It is less of a hit to upgrade a PSU than a CPU. Is Overclocking the CPU going to help? If not.....then the question is can I upgrade the CPU with out upgrading the motherboard?

Yes, overclocking the cpu will help some. I'd recommend switching to an intel motherboard/cpu for best results.

Yeah! that is great and all, but just having spent more on a GPU than I ever have, on-top of other hardware -wheel/pedals/shifter, amplifiers/tactile traducers, and two more screens all in the last year. Having to now replace CPU and Motherboard is really pushing it. But I struggle to understand that my " AMD FX-6300 Black Edition" is the issue as the Assetto Corsa web site states that: RECOMMENDED SYSTEM REQUIREMENTS: Processor: AMD Six-Core CPU, Intel Quad-Core CPU

Found your results... http://www.3dmark.com/fs/10729962 Looks like your cpu is throttling a bit as it's only running at 3.8GHz during the benchmark. Your cpu should be running at it's maximum turbo speed during the benchmark. The maximum turbo speed for your cpu is 4.1GHz. Check your cpu for overheating.

tweaked the CPU and ran the 3D mark again 3dmark.com/3dm/15968350

Thanks for the help and getting me to sort this out. The real proof will be to see how this goes with Assetto Corsa, but that will have to wait until I get back home tonight.
