  1. The red input voltage switch is not an encouraging sign for the quality of that psu, but if it lives up to the specifications, it should provide enough wattage, and enough amps on the +12v rail.
  2. 500W is plenty for that setup unless you have some crazy overclocks going on, though I don't know how the quality of that unit is - when it comes to power supplies, quality means a lot more than wattage.

    What does that red button do? Should I touch it when I get it?
  4. It requires a decent 500w psu, you have a decent psu.

    The load of the card+i5(and rest of the stuff, if you don't have much else) doesn't reach more than ~350w.

    Oh thank god, ty. Im not planning to overclock anything yet. But if im gonna do it, I would probably get a new PSU.
    Im planning to play BF3 on maximum, will the PSU still manage?
  6. That PSU is not a good quality one, and it's more intended for basic desktop systems.
    Here are some good quality PSUs;

    It's a slider switch, not a button, and you should make sure the voltage it shows matches the voltage of the AC outlet you're using.

    How do you mean? Is it the brand?
    And I already bought it, its coming tomorrow :(
  10. I think it's a CWT DSAII, it's used frequently by many manufacturers. Similar to the old Corsair CX500, it will do a little over 400w on the 12v
  11. You have a decent psu it's made by CWT, the same as the corsair CX.
    It will do, of course there're better ones out there, but if you don't have the budget for a new psu, it wil do just fine.

    People at Jonnyguru (Top rated site for PSU reviews) were not recommending it and claiming some bad things about it.

    At how much do I need to put it? I live in the netherlands, regular AC power sockets are 16A here.

    Total? or just the gpu???

    And that would be 350W measured at the wall, so closer to 300W actual PSU load (output) since PSU losses do not count toward output ratings.

    Yeah that's true cheap PSUs are underrated, it means that it will deliver almost a 400W without any issue, you should have asked before you make the purchase.

    Oh no, I just want to use it for atleast 6-12 months. Will it manage?
  18. Yes. Just change it when you get money and don't put the PC into too much load.

    How do you mean "into too much load"
    If I don't overclock, and put extra stuff in my build. It will be fine? Even if play most latest games on MAX?
    Also, what if my PSU breaks? Will it affect my GPU and Motherboard? Like they burned too?

    Meaning it will be probablly less than 350Watt?
  21. don't worry too much about it, it's a decent psu for the price. I've used it in a few builds with OC'd 2500k cpus and gpus in the 6850/7850 range. I haven't had any issues with them
  22. That psu can pull 400w at least...
    Your total load will not reach 350w...
    It's fine.
    But like others said, when you have the budget for a new psu, get a better one, since you're going to spend in another psu, get a modular psu when you have the money.
  23. Thanks guys, helped alot. I completely stressed out ahahah :D
  24. forgot to mention: If you're getting the euro version then it won't have the red switch on it, so you won't have to worry about that. The Euro version is N500-SA-EU

    Oh thank god, I would probably screw it up anyways, it reminded me of my old PC when I was around 5-6yrs old. I pressed a switch at the back of my case and there started coming smoke out my pc. Hahaah, dunno what I did back then.

    Even high-end single-GPU setups with overclocked i7-3960X and overclocked HD7970 barely reach 350W total PSU output.
  27. Send it back if you can and try to purchase PSU that is at least 80PLUS Bronze certified and modular; this is an easy way to determine how effective the PSU is and that the components are "good" and the modular PSU makes the cablemanagement easier and.

    Personally I choose PSU that are 80PLUS Gold or Platinum; for 100$ you can get up to 1000W 80PLUS Gold PSU which make the PSU "future proof" which lets you add gpus in CF/SLI or whatever, if you choose a PSU 600W or more,. You don't change the PSU for every build so a good investments in PSU with worth it.
