In doubt Antec Truepower 430 ATX12v

Hi guys,

I have being in doubt if my old PSU can handle my new upgrade? I read alot stuff on forums etc.

Some forums recommend and some not. ( reading thread not open one).

So i try to make a thead since i dont know much about psu. and the sticked thread dont have a 6850.

Current spec:

Phneom 9600 2.3 ghz not OC.
amd m3a mobo
4 gb ddr2 ram
8800 gts 320 mb (using alot watt like 20 more watt then the 6850)
1 raptor 150gb 10k rpm
1 data disk

Club 3D Radeon PCI-E HD6850 OC 1GB DVI/HDMI/DP
AMD Phenom II X4 965 Black 3.4GHz 125W Box AM3
Asrock K10N78D nF720D/ATX

my psu is old 4-5 years old. But should pull out 410 watt as new. being reading that the my new system will pull out around 310 watt in teori full load. but in games it would be alot less.

I could go for a weaker CPU AMD Phenom II X4 840/AM3 3.20GHz 2MB 95W no l3 cache but cheaper and using 95w instead 125w.

Any opinions?

  1. Do you want a new PSU?

    If so, specify what you prefer.
  2. That's an older PSU. I'm not sure how good it [still] is. I would replace it. A quality modern PSU has full range active PFC (no little voltage switch) and 80+ certification for efficiency (which also means it was tested at 100% load). Antec, Seasonic, Corsair, and Enermax are among the better brands with models in the 500W range.
  3. The TPII series was never that great to begin with.
    It's an old design and discontinued now.
    The TP New series is built by Seasonic and very good.
    I would buy at least a 500-650W unit for your set-up.
    650W are becoming the norm and priced very reasonably.
    Antec,Corsair,Seasonic,and XFX are the best.
    Seasonic basically oem's all of the aboved mentioned anyways.
    Antec TP New
    Corsair TXV2
    XFX all of them as far as i know.
  4. I would feel more comfortable recommending going the 840 route as that processor will draw about the same watts as your old 9600. If you go for that 965 it can draw up to 50 more watts, even more if overclocked. The capacitors in PSUs age and can lower the output ability to some extent. I think your asking for trouble if you push that PSU to its limits with the 965.

    I would probably retire the Antec PSU and go for the 965 with a new PSU that has ample breathing room. Risking your components to a PSU at its limit doesn't sound like a good idea to me.
  5. Hi thx for answers.

    Thought the psu failing would not affect the system, because inbuild "security"?
  6. still considering to get the 840 cpu and save money. or spend a buck and buy PSU/High Current Gamer HCG-620.
  7. I had an Antec 400watt PS, about 5 years old. Running an old Intel single core. I built a new system with an AMD Phenom 640 quad core CPU. Turned on the system would start to boot, then fans would shut off. Only the Green LED on the motherboard would remain. Press power on, nothing. Had to unplug the system to try again, BUT, same results EVERYtime.

    The problem, turns out the Antec 400watt was Really Weak from age. Even thou the system only needs 65watts idle, 90watts normal running, and 132watts under Prime95 & Furmark loading. That old 400watt Antec simply would not run the system.....

    Powersupplies get weak with age, the good news, new ones aren't that expensive. A good 650watt supply will run any CPU and any Single video card up to a 560 TI or 6870. Above that or for SLI / Crossfire at least an 850watt would be best.

    Go to Antec support and try out their PS calculator...
  8. Ye i god som weird problem with my current pc. sometimes ´pc would not react to i turn the pc on after i turned all power off from the wall switch.... thought it was the mobo and battery being old.

    i will spend the money and buy the 620 antec high current.

    any other recomendation at this range would be appreciated.

    it would always turn on after awhile
  9. Buying this:

    Club 3D Radeon PCI-E HD6850 OC 1GB DVI/HDMI/DP
    AMD Phenom II X4 965 Black 3.4GHz 125W Box AM3
    PSU/High Current Gamer HCG-620
    Asrock K10N78D nF720D/ATX

    Reusing my

    Main HD raptor 150gb 10k RPM
    4x1gb ddr2 ram Kingston

    Playing on a 1440x900 Resolution old samsung 19". buying a 23" later.

    I will be using single configuration for a long time. Not planning going crossfire.

    Anyone think how much procent i lost from not buying a new motherboard and ddr3 ram? and estimate?
