PSU Recommendation For My Build?

Hi, My computer has this power supply problem where it shuts down when i launch a game. Anyways, I want to upgrade my PSU. My current one was a Coolmax 550B(550w) and it was unreliable and died within a year.

Now, My PC build is:

-AMD Phenom ii x4 965 BE(Not overclocked)

-EVGA Nvidia GTX 650 Ti Superclocked(2GB VRAM)

-Two sticks(2x) 2gb ram DDR2

-Asus M4a78 Plus Motherboard

-2 HDD's Setup in RAID


A friend told me that my old power supply(550w) was more than enough for my build. So what do you guys recommend on me getting? Not too overkill on PSU and not to little. Is 500w fine? or should I get a more trusted brand 550w PSU?

Please leave your suggestions and thank you!

  1. You didn't need any more power capability than you had... you just needed a good quality PSU. I bet that 550W unit was only a 300W in reality. And cheaply made. Get one of these: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007657%2050001459%20600014021&IsNodeId=1&name=501W%20-%20600W

  3. like he said 500w psu is more than enough http://pcpartpicker.com/part/evga-power-supply-100b10500kr
  4. Go with any 500 or 550 W that is at least 80 plus bronze certified. It's best always to trust a certified Power Supply than a non-certified one.(Speaking out of personal experience.)

    The link below has PSUs ranging from 500-600W and all are certified:

  6. EVGA doesn't make the best power supplies.

    Another question. I heard that when doing gaming under heavy load like BF3 on ultra your GPU tends to draw out more power than the Manufacturer's recommended wattage. Is this true? If so are you guys sure 500w is more than enough?

    I'm not calling you liars I just don't want money to go to waste.

    Thanks again!
  8. For your specs a top brand 550w. is enough.

    Alright. Thanks man! I'm going to sort Amazon's results in best reviews and just get one that is certified and has really good reviews.

    Gonna do some searching now. Thanks again! I was a little worried thinking 550w was too low
  10. Stick with Seasonic , XFX , Antec , PC POWER.

    Quality over Quantity matters.

    Getting a non-certified 700W PSU might not be sufficient compared to a certified 500W PSU. I have had 3 RMAs for my CM Thunder and still to get a working one... I'm now asking for upgrade to one of their Silver certified PSUs.

    Certified 550W is more than enough for your build.
