PSU Question

I have a ~4 year old system that I just ordered a bunch of upgrades for, the system came with PS-109-118 ULTRA LIFETIME SERIES 600WATT PS
and still runs stable on it, my question is how can I tell if the PSU is still ok without having to go the multimeter approach?

I ask cause I noticed the fan for the PSU seems extra quiet, it is a top mounted PSU and so the fan on the bottom doesnt seem to move much air (hand up to it barely feel air movement) though it doesnt feel very hot there but on the back of the computer next to where the power comes into the PSU feels fairly hot (can put hand on it without pain but warmer than just warm) and I feel next to no air comming out from the vents there.

I went into the HW monitor in the bios and the voltage readings seem stable with some slight fluctuations
Vcore 1.42 to 1.44
+3.3 is 3.32 to 3.34
+5v is 4.92 to 4.96
+12v is 12.03 to 12.09

The system is currently stable with no lockups or fails I just would hate to get my new equipment in and installed and have the psu poof on me since my budget for upgrades is used up for the moment

  1. That's a very weak PSU..... if you want to test it for voltage variations you will need to stress it. Use OCCT which will graph all your voltages and temps during the GPU and CPU tests. I would not run the PSU test on an Ultra PSU, it might not survive.

  2. What is meant as weak? 600W is weak? or the amps? or the voltages?
  3. For a 600W to have only 32Amps +12volt.
    Ultra is somewhat notorious about using a peak power rating instead of the more realistic continuous power rating.


    Here is a the data plate for a budget Sparkle 450W PSU with 30Amps +12volt. (360W / 12v = 30A)
  4. I couldn't find the ULTRA PS-109-118 and I probably used the wrong ultra for comparison to find the 32A rating.

    What does the data plate on your PSU say?

    Budget PSUs (especially older PSUs) with wet capacitors tend to lose the ability to output full rated power over time.
  5. unfortunatly cant see the data plate unless i remove the PSU from the case
  6. What do you have now and what do you plan to change out?

    I ran the gpu occt test for about 20 min (stopped there cause the psu felt kinda hot in the back)

    There were alot of spikes (noise) in the voltages for example the 3.3v never went below 3.3 but did alot of jumping around from 3.30 to 3.34, the 5v started at 4.92 and at 1 min went to 4.95 and stayed pretty steady there with a few drops back to 4.92 and back up to 4.95, the 12v worries me it started at about 12.15 then at 1 min dropped to 11.85 then bounced between 11.8 and 11.9 the rest of the test.

    cpu core1 and 2 started at about 34c ramped up to a max 49c and gpu started at 33c at topped out at 75c (fan on auto) with a steady 48-49 fps all test long

    so according to this i am still within specs, I should prolly try to scrape up enough for a new PSU anyway you figure?

    what should I look for? single +12v rail or multiple? and what amperage? I think 500w would be enough if it was a true 500w continuous or do I need more?
  11. The thing that worried me the most was a new GPU going into the system.
    Since you've had the GTS 450 in service for a few months already I'm a bit less concerned.
    -> It's still a larger risk than I'm comfortable with, due the brand, it's age and a suspicion aging is taking it's toll.
    .
    The whole +12V amperage is the main thing. Single or multi-rail isnt important.
    I'll check the video card and see what the recommendation is like for that class of card.
  12. From the EVGA GTS 450 website:
    Requirements; Minimum of a 400 Watt power supply.
    (Minimum recommended power supply with +12 Volt current rating of 22 Amps.)
    One available 6-pin PCI-E power dongle

    That's for the whole system.
    Antec NEO ECO 400C 400W Continuous Power 80 PLUS Certified Power Supply $35 & free shipping 30Amps +12V
  13. I allways heard bad things about antec psu's, few friends I have had them and none lasted very long, could you give me a rundown of quality brands for me to look for while I price hunt?

    With the 870a g54 mb should I be looking for an 8 pin mb connector or 4 pin? I cant seem to find that info
  15. It has the 8pin EPS12 CPU aux power socket. But a 4pin ATX CPU aux power connector would work as well.

    430CX has a 4+4 plug to handle both 4 + 8 pin motherboards.
  16. Im looking around for some PSUs in the 500+550 range too.

    Any overclocking plans? future additions?

    overclocking is a maybe, I have never messed with it but the MB supports OC'ing with a switch (hear its crap) and I am getting the black edition cpu so I may mess with it a bit, next upgrade would prolly be an extra hdd after that prolly be an ati gpu so i can eventually xfire

    I like to have headroom on components so they will last thru an upgrade or 2, how does this look?

  18. CORSAIR Builder Series CMPSU-600CX 600W ATX12V v2.3 Active PFC Power Supply $60 $10 rebate and 10% off promo code +12V@40A
    A bit less than even the 500CX I think
  19. The Hec doesn't show the actual +12V amperage on the data plate.
    They mention dual +12V rails rated for 30A + 22A, but not what the PSU can actually produce.

    It won't be the sum of the 12V1 and 12V2 rails rating (not nearly 52A for example)
  20. I'd hate to have you pick the wrong PSU now for a future Crossfire addition.
  21. Corsair CX600 Power Supply (CMPSU-600CX)
    Voltage +3.3V +5V +12V -12V +5Vsb
    Max. Current 25A 25A 40A 0.8A 3A
    Max Combined Wattage 150W 480W 9.6W 15W
    600 Watts @ 30°C ambient temperature

    that will handle xfire if and when I get it?
  22. It would depend on the 2 cards and what power they draw.
    It would be OK for 2x HD 5770 or 2x HD 6850 for example. Two HD 5850 & HD 6870 should be OK too.

  23. It claims 48A +12V which is good to see. I couldnt not find any reviews that confirm it's a quality unit.

    Thermaltake TR2 W0388RU 600W website The Awards & Reviews tab is blank. Usually, a good PSU has the MFGRs listing the reviews and awards a PSU has received. If the MFGR isnt sending a unit out for reviews they might know it would have trouble getting a good review.

    You might want to punt this over into the CPU & Components section of the forum where the PSU guys hang out and see what they know.
  24. prolly end up with the cx600 its the best price / quality ratio ~$60 after promo and shipping, then I can stick this ultra in the closet as a "known good for now" backup/tester, to heal you all talk it sounds like i got lucky and got a good unit from ultra for it to have worked flawless for 4+ years running nearly constantly :sweat:
  25. Ultra has (some) good and bad stuff.... it's just scary not knowing which is which.
    The rep they have makes it hard to feel good suggesting them when there are so many really good units, albeit at higher prices, out there.
  26. If you can get the model number figured out run it by the CPU & Components guys, or post it here. You might have got that rare Ultra 'gem'.
