  1. The calculator you mentioned is a great general purpose guide, but isn't 100%. Nothing will be. However, you won't get any closer without using a wattage measurement meter between your PC and your outlet, which I've seen on Amazon for anywhere between $17 and $100, depending on features, brand, and seller.

    Knowing you have enough with what you currently have is great, but rerun the calculations with everything you plan to add in the future to see if your power supply will be sufficient.

    With just 1 more hard drive and 3 led fans, I'd say you should be just fine. However, I'm the kind of person that won't take someone's word for it without seeing the number's myself, and running the calculations. Recheck the calculations with all added future components you want and you'll see what your PSU can truly handle for you.

    Hi - Almost all these calculators add in quite a bit of headroom, so if adds to 461w, it's actually somewhat less.
    If you post your specs including the Cougar model #, we'd know for sure. Most CPU's fall in a fairly narrow range (85-125w), exceptions of course. But fans are less than 5w, so it really comes down to what GPU you are running.
  3. thx for response but the 461w ive said includes the 3 hard drives and 3 led fans whichs is my plan to add to my pc by the way what are the symptoms if my psu have lack of watts and what would be the effects

    Hi - I'll be redundant, need your sys specs. Fans which are less than 5w & hard drives which run 6-9w are
    inconsequential. 4Fans + 3hard drives is less than 45w. The GPU is the deciding factor, and you haven't listed it
    yet.

    hi here are my specs in the future i plan

    Cougar SL 80% 600 watts
    a10 5800k
    sapphire dualx vapor r9 270x
    asrock fm2 vg3
    3 hardrives
    1 140mm led fan
    2 120mm led fan

    Hi again - The key factor is the available +12v rail amps and not total wattage. The CPU, GPU,
    and hdd all draw their current from the +12v rail(s). I could not find a trusted review of the
    Cougar SL600. However, it is listed as having 40 +12v amps available.
    A system with an R9 - 270x needs > than 24 +12v amps, the SL600 is more than enough amps avail
    to power your proposed system.

  8. Your PSU will do just fine :)

    so the conclusion is that my psu can run these specs?by the way ive notice recently that my mobo has 1 chassis fan 4 pin slot and doesnt use can i put an additional 3pin fan in this slot?
  10. Yes you can do that easily. Like someone said above, the wattage is minimal, so if you have the room for it, go for it!

    Yes, the PSU has plenty of power for your specs. You can put the fan in the open slot, either 3 or 4 pin.
    It should fit only the correct way, but not always the case. You can also use a molex/peripheral connector
    for fans, but they will always run at top speed.
  12. hi a have another option can i use this external molex so that my power supply cant affect my specs and add more fans

    Yes, prob have to remove a couple plates from the back - but with fans drawing less than 5w ea, it
    really isn't necessary.
