What PSU to buy?

Hello

I've for nearly a year used a 750 Watt EPS-750W Ultra Silent PSU (that's an ATX PSU)
And I can see on the electricity bill, that this 60$ (very cheap, I know...) PSU is costing me a LOT of money!

So I wonder: Which PSU would you guys recommend me to buy, if I were to save some money on the electricity?

I've heard about someting called 80Plus?

Current PC Specs:
AMD FX-8120 (soon to be replaced by Intel i5 3750k)
--
Cooler Master 412S
--
nVidia GeForce GTX 560 Ti Amp
--
Gigabyte GA-970A-DS3 (soon to be replaced by ASRock Z77 Extreme4)

Thanks in advance

More about what
  1. 600W OCz or Corsair power supply would easily power your system, 650W if you want a little bit of room to do things like upgrading or overclocking

    But I have an ATX case; I can't see any ATX PSU's on Corsair's website.... Will one of their (ex. Corsair GS600 2013 Edition) fit in my case?

    Hi - Basically, if the descr doesn't say otherwise it's ATX
    compatible. Pls be aware that a sys with one 560ti can run fine
    on a quality 500w PSU and that has headroom.

    You want a gold, silver, or bronze rated PSU to reduce
    electricity costs. Gold more efficient than silver, etc.
    Keep in mind however, depending on your elect rates it will
    most likely take years not month's to recoup the cost of a new PSU.

    With that said, if you want to upgrade anyway, look for a gold rated
    unit if it's in your budget range. You have flexibility as you can wait
    for good promo deals on any quality brand psu 500w & up, actually
    could run it on a good 450w unit.

  4. One more thing to add here, just because a PSU is rated 80+, bronze, silver, gold or platinum even, does not neccessarily mean it is a good PSU. A quick check of this link can give you an idea of how good the design is http://www.realhardtechx.com/index_archivos/Page541.htm and the quality of the parts used.
    The 80+ certification is explained here http://www.hardwaresecrets.com/article/Understanding-the-80-Plus-Certification/742/3 (linked to the efficiency chart page)
    Hope it helps some

    And that's why I'm thinking of buying the Corsair Enthusiast Series Modular TX550M
  9. http://www.newegg.com/Product/Product.aspx?Item=N82E16817139028
    600W should be plenty of power unless you get really serious about OCing the i5.
  10. Now I've ordered the Antec High Current Gamer HCG-520M.

    Is that OK? It's because I wan't to only have the power that i need + max 50 watt extra, so I can save money on the electricity :-) Or do I need a little more power?
    (plz answer quickly so I can have time to cancel the order, if it's needed) :-)
  11. You should be fine with the Antec PSU.
  12. ya that should be fine its a quality ps and its modular +1 to u rokken

    Hi - tot wattage of the psu has nothing to do with your electr
    bill, the efficiency (gold,silver, bronze,etc) will affect your
    electr usage,(thought I explained that in an earlier post),
    not the psu watt capability. The PSU only pulls from the
    wall(efficiency affected) what your components need.

    The higher the efficiency the less it will pull & convert to DC current
    for your components.
    Unless you have super high rates, you won't see much diff in your bill on
    a month to month basis between a gold and a bronze rated units.

    The Antec 520 is plenty for your sys

    Platinum and gold rated models will use less electr than those
    below them,etc.

    example: if your components need 200w; at 90% efficiency the psu will
    pull 222w from the wall, at 80% efficiency it will pull 250w from the wall,
    and at 70% efficiency it will pull 286w from the wall, all 3 instances to
    deliver 200w to your components.
  14. yeah thats fine, 520watts will be plenty for ur current system and as toy said power bill goes with the efficiency in order. 80+ higher. to 80+ platinum to highest efficiency and lower power bill.
