Antec 900 and power supply

Hello all. i have just joined tom's hardware and i know i am going to get great help here. I have a sweet antec 900 gaming case and i am looking for a PSU that will fit with it. Now when i say fit i mean a PSU that has a long enough motherboard connector to reach the motherboard. I am looking at getting a MSI X58 Pro LGA 1366 Intel X58 ATX Intel Motherboard. I have been looking at PSUs with 900 to 950 watts. anyone out there have any ideas or have a 900 gaming case what PSU did you use? Thank you for your time and allthe help

  1. High quality power supplies such as Seasonic, Corsair, and PC Power & Cooling psu's have power cables that are long enough for the Antec 900. All three brands earn consistently high marks in technical reviews and comparisons. They're also the brands most often recommended by veteran posters at this forum. The manufacturers of cheap low quality psu's take shortcuts. That includes short cables.

    Is there any particular reason you are looking at a 900 to 950 watt power supply?
    What are the other components?
    Are you a hardcore gamer into serious overclocking?

    Here is a link to a power supply calculator:

    The results will be for an entire pc. In additon the results will be overestimated because there are a lot of low quality psu's of questionable performance that people insist on buying.
  2. ^Well said. Also remember: W= V*A.

    To find out the amps needed:
    A=W/V
  3. i'm having the same case.. and corsair tx 750 w.. its powerfull enough i think..

    but.. 900 have p supply down, so u have a lot of cables.. belive me i know..
    i recommend u tx 750
  4. I went with a modular PSU: SILVERSTONE|ST75F 750W RT

    Here is a link to my Antec 900 with pictures and components list.

  5. I went to antec website and found out i really just need a 500 to 600 watt power supply, not 900 watt. I was thinking i would need a strong PSU. But with antec site it seems kind of low in the wattage for having 2 9800 GT video cards, the specs on the cards say 400 watts per card. so wouldn't i need a stronger PSU. No i dont have any plans of overclocking...not yet. I will check out the places you suggest. I was looking at the http://www.newegg.com/Product/Product.aspx?Item=N82E16817371016 antec PSU.

  6. Nice build man!
  7. Willpower,

    Two 9800 GTX video cards operating in dual SLI mode use a total of 260 watts and 22 amps at full load.

    The source of the information is the recent article about actual video card power requirements here at Tom's hardware. There's still a link to the article on the home page. The power usage chart is on page 6.

    The specs on the individual cards are probably total computer system requirements.
  8. A pair of 9800 GT's[/] needs about 12 v @ 12 amps for both cards. 10 amps for an OC'd CPU. Figure 4 amps for 2 HD's and 1 DVD drive and an amp for case fans. That's about 27 amps at 12 volts. So, yes. A good 400 watt PSU will work. It won't leave you much for upgrading, though.
  9. jsc - Did you mean 12 amps total for two 9800GT video cards in SLI mode or 12 amps for each 9800GT? The THG article only listed actual power usage for the 9800GTX.
  10. ^He meant it sor a single 9800GT. (Imo, although it's only 12A actual, I would be safer with a good 12A on the +12 ATLEAST)
  11. Thanks for the link to that cool PSU power calculator, although... am I using it wrong?
    Here are my results (this is... or at least pretty close to my knowledge of what my dream PC would use)

  12. Kiwigamer - The system type is incorrect. It should have been single socket - which means just one cpu on the motherboard. You selected quad socket which means four cpu's on the motherboard. That's not the same as a quad core cpu which is one cpu that has four cores.

    That's both cards.
