    Hi all,

    I built a gaming PC. When I pressed the power button the LED's turned on for literally a second (if that)...then no sign of power. Took it to a PC repair shop & they told me the 500W PSU was dead.

    Sent the PSU off, ordered a new one (600w fixed cable corsair this time, even though 500 should of been plenty) + fitted in.....same problem. I took it back to the same repair shop & they were puzzled. They tested their 750w modular one....worked fine.

    The only difference between mine & theirs is that theirs is 750w (mines 600 which should be more than enough) and their is modular. Could it be something to do with the fixed cables....maybe the ones i'm not using? Maybe a unused cable is touching the case or something?


    Any ideas? really stressed.

    OK, the very first thing that just jumps right out at me is your choice of pw supply. The cx or builder series from corsair is NOT designed for gaming or any other stressful endeavor; it is for a basic build ONLY. Even corsair says it is only for basic builds;
    http://www.corsair.com/en-gb/power-supply-units/cx-series

    The next item I see is that you have some pretty mis-matched parts; you have a gaming video card and you installed a very basic ie low end mb. Asus is a fine mfg however the board you installed is one of their basic boards ie made to use onchip video, run office stuff, etc. In addition, you installed a WD blue drive. Again WD is a fine mfg however the blue drives are the low end of their product line. If you want a mech drive, install either a raptor or a black series drive; much better built AND a 5yr warranty. The blue drives have a 2yr warranty; that alone should tell you about quality.

    Actually you did not. You built a low end computer with a gaming video card. For a performance system, ALL of the parts need to work together. What you have is analogous to putting a high performance cam into a yugo; it is just not going to work well. In the case of a gaming system, the pw supply must supply stable, clean pw, the mb must be capable of supplying the needed current through the pci-e slot, the VRs on the board must be capable of supplying the needed pw, etc, etc.

    Just for your information, corsair does not mfg their own pw supplies. The high end ones [hx, tx, or ax models] are mfg by seasonic [maker of very high end stuff] The cx line is mfg by ctw [maker of oem stuff] In short, when you use a cx pw supply, you have basically a dell/hp pw supply.

    So you are saying I should get both a new PSU+Mobo? Now i feel awful....I built this as a present. The parts were all recommended to me by a forum.

    First of all, I would NOT go back to whatever forum recommended those parts.
    If the system worked at the shop when they plugged in their test pw supply, then it can really only be one thing; your pw supply just does not supply the needed pw. The only other thing even possible is that you did not fully plug in the aux pw connector ie the 4 or 8 pin connector near the cpu. As for unused connectors, you bundle those up with a tie wrap and store in an unused 5 1/4 bay.

    Up to you if you want to get another mb however I would not tell someone it is a "gaming system" with that board. The mb is most likely not causing your problem and will work with that video card. It is just not going to deliver the same level of performance that you would get with one of the z87 pro type boards from asus.

    Thanks man,

    I feel awful tbh.Going to try plugging it all in again when I get home.
    What PSU would you recommend (bear in mind i'm on a budget)?
    How much performance increase would a new mobo be?

    Good ie recommended pw supplies; corsair [only hx, tx or ax models] seasonic, pcpower&cooling or FSP [only units with the 5yr warranty]
    This is an example of what you need;
    http://www.newegg.com/Product/Product.aspx?Item=N82E16817139012

    That is difficult to give you an exact answer. With a performance mb from asus or gigabyte, you have a more stable system, mb chipset runs cooler, etc. As for actual fps in games, it would end up pretty close. The "performance" comes from a stable system, runs cooler, etc ie the mb is designed for gaming and or overclocking.

    The corsair one is decent however the coolermaster is only an oem unit.
    Really if you want to be sure you fix it this time, stick with ONLY the hx, tx, or ax models.
