The difference between a good and a poor source, connectors, noise and starting cold sources - hardware workshop

Hi friends, in this hardware video tutorial will show you the difference between two sources, one dozen product (or brand-forget) by Aline and the other a good source produced by Seasonic.
On paper, a dozen sources may seem better, because it has 450 watts and the Seasonic has only 430 watts, in reality a source must do more than "consume 450 watts from the network". Some time ago I spoke to you in a guide about purchasing a source hardwareI said in detail what must be careful, how to choose the source, I even made a few recommendations, now we do a test live, we'll see what connectors comes every source equipped, how loud or quiet is as a bonus we learn and how we can turn a source that is not mounted to a computer. WARNING: Do not play with your sources, even if they have only 12V, 5V or 3.3V, you can stop the heart in a split second.
Source Seasonic has certification 80 PLUS Silver, that means 85-90% of the input electrical power from the grid is converted into direct current (DC) useful for the motherboard, components and peripherals, remaining 13-15% are lost to the atmosphere, this loss is called residual energy (heating parts inside source). We have to consider that the best performing sources in the world (products at the moment) certified 80 PLUS Platinum have an efficiency of 90-94%, regardless of the workload incerdibil but these sources are expensive. In conclusion, our source is very good for its price.
For those who want a trusted source at a good price is perfect source if you have only one video card is ok, the source will do the job quietly. I processor i7 2600 with a Nvidia GTX 460, 3 HDD, 1 SSD, 1 DVD, TV tuner HD and everything goes smoothly, I put it even in stress, Prime95 + FurMark almost 3 hours, the source did not even to overheat, fan sitting at 50%.

Source Seasonic S12II-430 Bronze, ATX12V, 430W

    Hi, can you tell me please Cristi numeleaplicatiei nice on the phone? thanks!

    The application used by me in tutorial for measuring the level of noise is called Noise Meter and is available in Market, or whatever Google Play.

  • Cristi, I knew the thing you started but was using tweezers but I have a source Astec of 145W that if I give impetus not start a little trembling fan and ready, but if you put it on the motherboard goes smoothly, do not know who would be cause . And I have one of the Compaq ATX 150W that if you give that momentum going razor do not know what the problem

  • It would be recommended that testing, or installing a source to use an antistatic wrist strap.

    Hi! Please tell me what you filmed? Thank you!

    With a video camera.
    If you are curious to know the model, Panasonic HDC SD20.
    I do not recommend to buy, it would not be good, but there are better choices on the market now.

    This is not about the pulse, the green must remain in contact with the black, if you want your source to work, the pulse work is valid on the motherboard, where you short-circuit the "pwr_sw" pins at the bottom of the board. the base.
