Seasonic S12-330W

[AsAsIn8eR]

I have this PSU.What do you think?Can it handle thisFI NF3-250GB/1GB g.skill HS@ddr500-3-4-3-8@2.8v(UCCC)/1x160GB WD 1600JS SATA 2 HDD/1xDVD-RW LG 4167B/ATI R9600 vid./.3x120MM nexus fans/1 leadtek tv 2000xptv-tuner/AMD Sempron 2800+ palermo e6/1 cold cathode.Can it handle it?I overclock to 2760mhz 1.7v in CPU/1.8 in chipset/2.8 in ram.Can it do it?A friend says that it can't handle it not even now with a 2MB PCI vidcard and 2x80mm fans instead of the other fans and the 9600 radeon. and that is all.I currently have 11.9v on teh rail in full.But a friend that says it's low.I'm overclocked to 2.6ghz with 1.6v.

Re: Seasonic S12-330W

It can handle it just fine, I'm willing to bet your computer does not even draw 200w full load... If you have the equipment needed make a test yourself...

All your components has excellent performance / watt ratio...

11.9v on 12v is totally within spec, the spec allows a variance of +-5%...

And also; unless you check with a multimeter you have no way of knowing what the voltage reported actually is... The real voltage could be higher or lower, mainboard sensors are generally seen as being fairly inaccurate...

Re: Seasonic S12-330W

That was checked with multimeter.Software shows 11.8v.I need to picjup a DMM cable and a battery for it since I wrecked the cable and the battery is slow.

Re: Seasonic S12-330W

Per Hansson is right. Your s754 system will hardly pull 300w from your PSU, but probably 80W-150W is about make sense. This article will ilustrate it better about comparison of power distribution in six typical modern PC systems.

Re: Seasonic S12-330W

Yes but did you take in mind that I overclocked?

Re: Seasonic S12-330W

Well, i have a Semperon 3100, currently @2200mhz, limited by the bad Mainboard. 1gb vs corsair and x800@500/500, 2x hdd 7200rpm 3 x 90mm fan.
PSU is Amacrox Frei Erde 500w (got i for cheap), my cheap power meter states an absolut power of 150w if 3dmark and prime is running at the same time. Even with 1,6v there anren`t mutch difference. If c&q is activated, power drops to 70 tro 65w.
Prime95 only will load the psu only up to 70 till 100w.
So your rig will probably near the 200w to 250w realy( probably mutch less). Keep in mind, that your vid card will use even far less power than mine.
As long as 3,3&5V load don`t exceed the limit (probably only some DFI boards will do that) your are fine with it. But in any way, if you have some money to spend you can alway spend it to a better psu. As long as is of the same quality as the current. Keep in mind, that you will not get anything improved in buying the next cheap 400 or 500w rig. Then you probably has given up more with your very good S12 330w.
I think, you absolutely don`t need an upgrade.

The messured value is normaly meaningless, as long as it is within the ATX tolerance.
So don`t worry, i know to mutch people, refusing to follow my advise to buy a decent brand named 350w FSP PSu insted a 400w or 500w cheapo crap.
May be in the end, if the 500w cheapo crap has ended the cruel game of problems by frying the whole system, they will have been learned the lesson.
But probably they will buy a 600w cheapo rig next time.

That is so true and is what I tell all my friends who ask for advice, yet this is actually the first time I see it on the net, it should be made a sticky in all forums on the web :P

Re: Seasonic S12-330W

Then I'm settled.I was going to sell it but now I'm gonna buy a nice sleeving kit and get it fixed for mariage with my system.

Welcome A. ,

The others have already cogently answered your question, it seems, so consider this more advice than any kind of answer.

Your Seasonic S12-330 should, to all intents and purposes indeed be quite sufficient for your system - in no small part due to the fact that your board powers its CPU VRM entirely from the 12vdc "rail". It would have been a matter of concern if you had been using some of the Socket A boards, for example, which do often power practically everything from the PSU's +5v output. With an overclocked CPU and a 5v-fuelled card such as the 9600, the Seasonic's maximum rating of 120W for 3.3 and 5v output combined could easily have been exceeded.

Interestingly, the specs (I've attached a shot, cut from the Newegg.com website) for your PSU show the 12v divided into two rails, one of which is considerably more capable than the other. Perhaps you could verify whether your 4-pin CPU 12V connector is indeed powered from the 14A-rated rail - in which case you would have even less cause for concern.

...


PS. Not too sure about that "OUPOT" though.

Re: Seasonic S12-330W

12V2 does indeed feed the 4 pin ATX.

Re: Seasonic S12-330W

12V2 does indeed feed the 4 pin ATX.

That's a good thing. Do you know by any chance what the 8A-rated output powers? The molex/sata connectors only or the 12v feed on the 24-pin ATX plug too?

Re: Seasonic S12-330W

tiresias, I looked but could not find an iron clad link to just how the rails are distributed. This is a review of the more current model with no internal changes, http://www.silentpcreview.com/article596-page1.html

http://www.formfactors.org/ has shifted things around on thier site since my last visit there. Depending on revision number, things change a bit.

I would bet that 12V2 serves all ATX 12V needs to include the 20/24pin and that if the 12V1 needed 9A, it would be able to get an AMP or two off the 12V2. The 12V1 serves all other rig needs, graphics, HDD, opticals & fans. I have a quad rail PSU, the 12V4 is rated at 8A but can rob off the other rails for a total of 18A. Go figure. It's just the way they do things to cover thier butts.

To the OP, AsAsIn8er8, this unit will carry your system. Please do read the review I linked, note the temperatures at full load. Now, if you have high ambients and are running near full load often, I'd up-rate the fan in this quiet PSU. The stock fan draws .24A or 2.88W. Consider a fan that draws .3A or 3.6W. Your PSU will thank you with longer life and better stability.

Re: Seasonic S12-330W

I have the revision with Yate Loon.I wouldn't like to open my PSU since it has warranty.Maybe after that.The temperatures are very good.The PSU is cold at touch.I meen not hot.
