Is a 530w PSU enough for me?

Is a 530w PSU enough to power below parts? I, like the spaz i am, already ordered it!

ASRock AM3 870 Extreme3 motherboard
AMD Phenom II X4 965BE CPU
4GB (2 sticks) of DDR3 1600
1 ATI HD5970 GPU (in the near future...) I will be running just a Saphire 3870 that i already have for now. (Note:I AM NEVER GOING TO CROSSFIRE/USE 2 CARDS!)
2 7200RPM SATAII HDD's (in the near future... will be running 1 600GB 10,000RPM SATAIII HDD and 1 2TB Hitachi SATAII HDD)
2 120mm system fans
At maximum 3 USB devices will be used (only 1 USB 2.0 item will be always plugged in)
There will be no other parts installed ever except the possibility of a PCIe x1 TV Tuner, highly unlikely though.

The PSU in question is a RAIDMAX HYBRID 2 RX-530SS 530W ATX12V V2.2/ EPS12V (Before anyone says how crap it is I've read several posts about how i need to get a Corsair or somethin else but the RAIDMAX has a 4 out 5 newegg rating and it was in my super tight budget.). I've used several PSU calculators and they show that it will be fine (except newegg's calculator, it was showing that i needed like 715w to 750w which i already know is outrageous). I am looking for some serious factual opinions on my situation.

Thanks a million for reading. Info will be greatly appreciated.

More about 530w
  1. Hello lt200420;

    Here are the PSU requirements for a HD 5970.
    "650 Watt or greater power supply one 75W 6-pin and one 150W 8-pin PCI Express power connectors recommended (850 Watt with two 75W 6-pin and two 150W 8-pin connectors for ATI CrossFireX technology in dual mode)"

    Send it back. Don't bother to unwrap it.
  2. Not to sound like a dick or be undermining your statement WR2 but...

    I already know that GPU companies ALMOST ALWAYS overstate necessary power needed.

    According to with everything stated above (including AMD 965BE (125w), 5970, 2 120mm LED fans, 1 10,000RPM HDD and 1 7200RPM HDD, etc etc) it states that i need 516w.
  3. Did you add an ODD and the correct number of USB devices?
  4. with 3 usbs and odd its 518w sorry about that
  5. What did you add for Capacitor aging? I got 585W (530W minium) when I ran the PSU Calculator @
  6. i didnt add Capacitor aging at all :( thx for that. i read the footnote that i would be needing 20-30% increase since my pc will be on 24/7
  7. I have nothing against that particular Raidmax although the brand does have a bad reputation. The main concern is you're going to spend $600 on a video card and you want to be sure... be REALLY sure... you're not going to have a power issue.
    Plus.... having that video card - you REALLY want to be able to overclock the X4 965!
  8. Just so you know - I'm usually the guy telling people that don't need to upgrade to a bigger PSU.
    Is a Corsair Vx450 enough for me?

    If you've just ordered the PSU tonight you might be able to cancel the order before it's shipped.
  9. i will be using my old 3870 for awhile anyway until the 5970 substantially drops in price (guessing a year or two).

    with that said im under the assumption (from website and newegg reviewers) that the ASRock 870 Exrtreme3 will be ultra easy to overclock the 965BE to around 3.8ghz on air and DDR3 to 1600 in the BIOS (like 1 "click" is what i understand).
  10. You won't have a problem with the Asrock 870 Extreme3 and getting your X4 965 OC'd.
