Wanted to ask if my power supply is good enough

Hi
i just bought a new system

CPU: Intel E6600
MB: Asus Striker Extreme, BIOS : 0801
RAM: 2 X 1 Giga Corsair PC 8500 Dominator
VGA: Geforce 7950 GX2
HD: 2 X 250 Giga WD SATA 2 , 16MB
DVD-RW: Nec X16
Power Supply : Hec 580W

ive been having some troubles,
i install windows and all drivers very smoothily, but when i start installing the vga drivers , the windows becomes unstable, start flickering, and becomes verly slow, sometimes even restarts, i wanted to know can that be a lack of power problem , or is the 580w is enough for that setup ?

More about wanted power supply good enough
  1. 580w should cope with that setup, but I am not familiar with the maker's name. Is it a top name in your country, or not?
  2. wow man, you are speaking greek to me.

    1st , i always use the latest drivers for everything.
    2nd, these are the details from the hardware monitor --> voltage monitor in the bios:

    vcore 1.29v
    memory 1.87
    1.2v HT 1.24
    NB 1.23
    SB 1.52
    cpu vtt 1.23
    ddr termination 0.92
    3.3v 3.26
    5v 4.94
    12v 11.64


    tell me if these data is any help
  3. hi,
    the PSU is "hec ace 580ub"

    +12v1 18A
    +12v2 17A
    -12V 1A
    3.3V 32A
    5.0V 38V

    Combined $$ + $$ = 240W
    TOTAL MAX 580W

    hope this is more helpfull
  4. hi,

    so you basically saying that my problem is a lack of juice,
    if ill take a 650W or above will that fix my problem ?

    also is that logical that the computer works fine while the vga card driver is no installed, but when i install it problems start,
    does the vga card start draining the psu only after it is installed via drive ?

    thank you man , you are really helpful
  5. hi
    but my PSU supply 12v1 17A + 12v2 18A
    shouldnt that be enough?
    did u check my model it should be a great powerfull PSU,
    it has also the SLI and Dual SLI ready sticker.

    also , can you recommend on some models i should get instead of the current one i have ?

  6. hi
    what about the hec sigma 650w will that do the trick?

    http://www.hec-group.com.tw/special/sigma650/Sigma650.htm

    it has 4 12v sockets, 16A etch
  7. cool man ,
    thank you very much for your pro help.
    i just hope that upgrading the PSU will actually solve my problem.
    is w the system becomes real slow and monitor turns on and off every second or two, are a know symptoms of having low juice ?
  8. im thinking of buying this PSU, i need your aknoledgement,
    its a modular PSU 620W corsair, should be very good.

  9. The Corsair is a great choice. That's the first top notch model you've mentioned and it will certainly meet/exceed your needs.
  10. ok , so i will get it,
    here in IL i can buy it as a dealer (chepest price available) in about 200$

    By IL I assume you do not mean illinois since it is routinely available for <$150 here in the states.

    So it's going to cost you $200 as a dealer. You relize it's on Newegg for about $170 right?

    Not to mention the $15 mail in rebate. Think you might want to fire your supplier.

  13. by IL i mean ISRAEL :D

    its a bit expansive around here, the STRIKER EXTREME cost me 375$
    and the Hec ACE 580W + A compucase server CASE cost me 133$

    unfortunantly, Buy.com and newegg dont shit here, not to mention the rebate :)
  14. BTW
    hows the
    THERMALTAKE THOUGHPOWER 750W 4X 12V RAILS , 60A/12V, 2.2 VERSION, ACTIVE PFC, INDUSTRIAL COMPONENTS, 140mm Silent
    FAN, EPS12V SERVER SUPPORT, 2X PCI-E (SLI & CROSSFIRE SPEC)

    i can get it for 190 $ , which one is better ?
    what should i choose ?
  15. That TT is an excellent tier 2 unit, check out jonnyguru's review. It can handle at least 55a on the +12 (vs the 50a for the corsair) so it is an excellent value for the dollar.

    He also reviewed the corsair, which is no slouch but things got interesting on the +12v2 and +12v3 when the load hit 40a so it is worth a read since you are considering both.

    I would probably go w/ the TT since my wallet usually dictates the purchase for me :wink:
  16. yeah, but i already spent like 3000$ on my new system 2 mounths ago (which i never used yet), so +- 10-20 dollars are the least of my worries.
    :)
    i really liked the modular cables on the corsair , but if you say that the TT provides more juice , ill take it, who knows in the future i might upgrade to quad SLI, so every extra power is important :)

    Kingston 3200 1Gb
    Radeon 9700
    ACE 480W

    I need to get a radeon 1950Pro AGP can my powersupply hold this card
  18. i ordered the TT 750W i realized he is modular too, so i was double happy,
    i just hope that after all this mess it will solve my problem

    What's with the caps man?

    Never heard of an ACE power supply. And neither can I find any on the web.

    Ok if that combined is the combined +12 rails, i found the unit on line and it would seam that it is refuring to the +12v rails, then the PSU isn't powerful enough. Your system under a heavy load is pulling about 280+W from the + 12v rails. So your about 40 Watts shy of what's needed. Actually you are about 80W short because you need to have a little exstra room so as not to overload the PSU.


    WHy are you saying it's the PSU? according to this rather exhaustive list of power useage by graphics cards, the 7950gx2 uses roughly 110 watts at full load.

    Am I missing something? Unless his PSU very close to dying, there's no way it should have any problem on the desktop running his machine, just because he changed drivers. I could maybe see it (though I'm skeptical) if he was playing games when it happened or if he was playing a game an in SLI mode, but one card (not even a GX2) is not going to stress a non-defective PSU with 280w on the 12v rail.
  21. actually i am using the GX2 video card. it's like 2 cards combined
  22. so how come my hec cant run the system ?

    it has about 35A
  23. ohh :oops:

    but anyway i have one rail with 17A and the 2nd is with 18A,
    its more than 11.5A + 13A

    also what does the rail management, who decides what device uses what rail ?

    As you can see he just put that system together. Now the PSU is listing the combuned power of 240W. Asuuming that is for the +12v rails then the PSU is only supplying 20A to the +12v rails. This is falling just a couple amps short of the power needed for this system. The system pulls about 297W from the +12v rails which is about 24.75A. As you can see he is about 5A short of the power needed to run this system.

    My point is that he's implying that the problem is occurring immediately after installing new drivers. That system is NOT pulling 240 watts running office apps, much less at idle.

    If your research shows it's only got 20a on 12v rail, then it's not a very good PSU (especially considering the specs it claims) and it should be replaced, but I'm still concerned that the issue is elsewhere, because a E6600 at stock, 2 HDs and virtually any single GPU shouldn't stress it outside of games or perhaps while running prime 95, superPi, folding@home etc. At idle, his system is likely using no more than 160 to 180w....possibly less.

    Regardless, he doesn't need $200.00 (or 170 via newegg) PSU. I'm sure we could both point to any number of sub $100.00 PSUs that would supply more than enough power for his rig.

    This one (warning PDF spec sheet) indicates that it can output 460w(I could be wrong on this one, but normally fortron'd specifief max is max continuous output, not peak) and it's under $50.00 from newegg.

    But if I"m misreading it, then there's always its big brother (under $90 from newegg and reviewed 2 years ago here on spcr

    Or get this one
  25. just got my new TT, it is amazing.
    unfortunantly problem still on :(

    That's what I suspected would happen. You don't use much power at the desktop. If I had to guess, I'd say you've got a problem with the card itself.

    However, what I'd do is download drivercleaner (I'm assuming your'e on XP and not on Vista) from softpedia or majorgeeks (this version is about a year old, but it should work....I believe newer versions are pay only and cost 10 bucks....probably worth it, but I'd wait till vista is out).

    Follow the directions then reinstall drivers (get the latest). If that doesn't wokr, return the card for a replacement (or try it in a friends machine and see if he/she has the same problem).
