    Jim,

    sorry no OC update yet, had absolutely no time this week hehe,

    BUT...

    I just upgraded my PSU to the X-650, it was a fun installation, I love how modular it is :)

    Stupid question... I was not able to understand if I need to connect its fan to the Motherboard?

    I didn't see any cable for the fan... does it just work without being connected to the board? When I plugged it in I did see the fan twitch for a second and then it stopped, I know that's how it's supposed to be just to let you know that it's alive because its basically fanless...

    But is there a cable I missed that needs to be connected to the PWR FAN socket on the mainboard?

    Thanks, great PSU!!!

    Good choice, the X650 should easily fit your needs unless you want to go crazy with crossfire and extreme gfx overclocking.

    There is no special psu fan cable.
    A few power supplies have a cable that connects to a mobo fan header so that the psu fan speed can be moitored.

    RTFM!! Read the flaming manual.
    The X-series power supply fans don't start to spin until the power load reaches about 20% or more, and then it spins at very low rpm. Check out the fan speed graph on the back of the box. The psu runs in fanless mode up to about 25 degrees (C).

    Modern power supplies have their own built in fan control circuits.
    Check out post #70 MSI N460GTX Hawk (1GB) Overclocking Results for my latest posted GFX temperature and power load test.

    Hehe yeah I know it's fanleas until 20% and I did read the manual :) Just wanted to confirm that it powers the fan on it's own and no cable needs to be connected to the PWR FAN socket on the mainboard.

    Btw it was so much easier to arrange the cables than with my Enermax...

    Yep, the 100% modular cable setup and the Seasonic's size makes installation easy.
    Enjoy your new power toy. ;)

    Thanks, I will, although I did have to pry out one of the case fans in order to fit the cables in properly into the PSU, otherwise, they would have been caught in the fan...

    Anyone wants to buy a 3 speed adjustable 120mm Antec fan?

    Or alternatively, I may need to find a place to stick it in hehe.

    Ok now that all the upgrades are done, back to the OC, gonna try 3.8 again today with your recommendations. Wish me luck :)

    EDIT

    940x4200 –-- gpu = 66 –-- VRM = 50 --– Choke = 61 --– AC = 2.9 amps –--- psu = 357 watts
    God damn... Kombustor really loads up the GPU like Furmark does... 357W, sure it is safe to overload the GPU so much? I'm kinda scared it might damage my card...

    What's the safest application to check for GPU stability without the chance of hurting the card? I used ATI Tool a couple of time but it's not such a good indication, because it didn't catch artifacts or freezes that appeared pretty shortly after I fired up Unigine Heaven...

    357 watts is the total system load on the psu, not the total video card load.
    Running the Kumbustor test without PostFX processing results in total psu load of 300 watts.

    Another punishing test is the OCCT PSU test which simultaneously runs Linpack and Furmark. With this test you can select full screen mode or a smaller windowed mode for the Furmark portion of the test.

    It's my understanding that video cards are usually limited to about 225 watts of power unless you override the default safety settings.

    With your new X650 psu running at 80% of its rated power, your maximum safe sustained output is 520 watts (650 x 80%).

    I've found that the Heaven 2.1 benchmark demo to be the most demanding DX11 test on my system. With maximum overclocks, Heaven is stable only up to about 910MHz where the other benchmarks ran without problems up to 925 - 930MHz. These tests were run with the maximum gpu voltage settings = +100mv for my video card. These overclock speeds are 17 - 19% higher than the stock 780MHz gpu setting.

    Yeah I understand it was 357W for the entire system, but still, pretty impressive...

    I'm going to overclock my GPU as soon as I'm done with my CPU Overclock, should I use Kombustor to test stability? Is it safe? I read somewhere that Furmark had damaged quite a few cards in the past and that Kombustor is pretty much the same thing...

    Kombustor is a somewhat "kinder/gentler" test based on Furmark. Both of these tests might complete without any screen artifacts, but your system still might fail when running gaming benchmarks or demos.

    For me, Kombustor and Furmark are similar to IBT or LinX, in that they are not as comprehensive as running Prime95 or OCCT when doing cpu/memory stress testing. I only run Kombustor or Furmark for 5 - 10 minutes during preliminary video card stress testing. The Heaven benchmark takes less than 5 minutes to complete its benchmark test. You can also run endless loops with Heaven when you don't select the benchmark mode (F9).

    I totally agree, when I OCed my 5850 I ran Furmark and it didn't show an artifact even once, but Unigine Heaven froze several times until I had to lower down the core clock speed

    I guess the real test is just using your hardware :)
