Do these readings sound about right...

Thx for the help. I am having some strange problems and I think it is my PSU do these readings indicate anything to anybody:
+12v--->12.224
+5v---->4.919
+3.3v-->3.228
And Vcore for my Athon 2400+--->1.632

More about readings sound right
  1. You might be a little low on the 3.3v rail but well within spec unless you're trying to feed some BH-5 3.3v.

    Abit IS7 - 2.8C @ 3.4ghz - Mushkin PC4000 (2 X 512) - Sapphire 9800Pro - TT 420 watt Pure Power
    Samsung 120gb ATA-100 - Maxtor 40gb ATA - 100
    Sony DRU-510A - Yellowtail Merlot
  2. Your voltage readings seem OK. What you need to tell us is what your Amperage (A) ratings are on your PSU. Also, what are your system specs, specifically what brand/rating PSU are you currently using?

    XP2200+, Abit NF7, 1GB Dual-Channel DDR333, ATI R9800PRO 128MB, TT PurePower 420W, Samsung 120GB, Maxtor 120GB, LG DVD+-R/RW, WIN2K PRO SP4
  3. The PSU that I am using is an OKIA??... 430watter. My specs are:
    2400+
    A7N8X
    BBA 9600xt
    DVD-rw
    DVD-rom
    2 hard drives
    6 case fans
    2x512 Kingston pc2700


    <i> If the creator of the human body is "The Ultimate Engineer", why did he put a recreation site right next to a waste treatment area? </i>
  4. Never heard of OKIA. What you need to do is take the side of your case off, and read the label on the side of your PSU. It should list voltage and amp ratings.

    For example: +12V 20A
    +5V 15A

    Those are the ratings that matter. I had a 350W PSU that was crappy, and wouldn't run any kind of 3D app simply because the amperage was too low on one of the voltage rails.


    XP2200+, Abit NF7, 1GB Dual-Channel DDR333, ATI R9800PRO 128MB, TT PurePower 420W, Samsung 120GB, Maxtor 120GB, LG DVD+-R/RW, WIN2K PRO SP4
  5. OKIA's in the middle of the pack. Two mice and a treadmill could run that PC anyway. Look elsewhere for the problem.

    Abit IS7 - 2.8C @ 3.4ghz - Mushkin PC4000 (2 X 512) - Sapphire 9800Pro - TT 420 watt Pure Power
    Samsung 120gb ATA-100 - Maxtor 40gb ATA - 100
    Sony DRU-510A - Yellowtail Merlot
  6. You could be right, but I wouldn't discount the PSU, depending on the ratings per voltage rail. I had a crap 350W that would crash the whole system everytime it tried to run a 3D app, and the system was almost identical to BossHoss, except it only had 1 HDD/Optical Drive, no fans, and only 1 stick of RAM.

    If even one of the voltage rails is underpowered, that would cause all kinds of random crashes.

    He could also try <A HREF="http://www.memtest86.com" target="_new">MemTest86</A> and see if it RAM related, as bad RAM causes all kinds of weird errors as well.

    XP2200+, Abit NF7, 1GB Dual-Channel DDR333, ATI R9800PRO 128MB, TT PurePower 420W, Samsung 120GB, Maxtor 120GB, LG DVD+-R/RW, WIN2K PRO SP4
  7. I don't disagree with you Spark, but unless he doesn't have 15a on the 12v rail I can't see a problem with these readings. He's just not drawing that much. Never-the-less, power supplies have died like this in the past.

    Abit IS7 - 2.8C @ 3.4ghz - Mushkin PC4000 (2 X 512) - Sapphire 9800Pro - TT 420 watt Pure Power
    Samsung 120gb ATA-100 - Maxtor 40gb ATA - 100
    Sony DRU-510A - Yellowtail Merlot
  8. I put very little faith in the rail ratings of power supplies. For example, I've never overloaded a power supply, yet my Antecs would start dropping voltage at less than 70% of their rated capacity. Antec later added the "True Power" series using the word "True" in reference to everything else they sold being a lie.

  9. ok, it says +12v=18a +5=38a +3.3=23a

    And one more question, I am upgrading to this:
    3500+ s939
    MSI Neo plat 2
    2x512mb kingston hyper x
    BFG 6800gt
    2xseagate 160gb for raid 0
    Dual layer lite on dvd-rw

    Am I gonna need a better PSU for my new setup?

  10. 18a on the 12+ line is enough for that system. However if you are buying all that, whats another $50 or so dollars on a quality PSU?

  11. With these voltages sitting well inside a +/- 5% operating window, I'd say you were doing pretty good. And better on the low side than the high, since power dissipation will be a little lower overall in the regulators/switch mode PSU's to supply VCore and VDIMM
