From Overheat?

please...

You are reducing the intelligence of this forum. Let’s keep to the topic. He has a 12V rail out of spec. That’s a fact. As you agree it can cause overheating, so why does your noob hardware have anything to do with it?

Marcuz, please borrow or buy a new quality psu. That will solve the problem.

The PSU is FINE! What do you not get?! Yes, they don't add together, but they still go to the motherboard, just not as one! The power supply is plenty sufficient for Pete's sake! Go ask anyone on this forum!

CPU - Core 2 Duo

Mobo - High End mobo

Memory - DDR2 2GB x4

ODD - DVD-RW

HDD - 10k RPM 3.5"

Recommendation: 409W...

Hmm... I think 750W is enough.

Marcuz, do not spend any money on a new PSU. Bigfella hasn't proven that it needs replacement. A number of things could be causing your problem, but I doubt it's the power supply.

The 12V rail is OUT OF SPEC. PERIOD. Unless you guys have a multimeter and are willing to go to his house and test it, then i think speedfan showing 10V or less, and PC Wizard showing the same is good proof. ATX standard says +/-5% or 10% under load. This is well and truly out of spec and the likely cause of heat.

Do what you want. The PSU needs replacing, it is not about watts, its about what the 12V rail can provide in amps..

Marcuz, if you have any sense, borrow a PSU (quality) with a good single 26A or great 12V rail and test. If you want further help along this idea, pm me.

Then explain my miracle of a sig. I have 19/20 on my 2 rails. 25A minimum, 30A recommended on the HD3850.

The +12 rail is fluctuated quite abit more than recommended.

It wouldn't hurt to try another PSU, if one is handy (when is this ever the case though T.T). I'm not altogether convinced however. Last build I had a piece of shit unit, rail output was all over the place, most the time worse than OP's. Yet I never saw a single problem, heat or performance wise. Well, till it blew up.

pff that's rubbish, what education do you base that assessment on? btw, unsufficient isn't a word - it's insufficient. You have been ridiculed and booted out of tech support fourm (www.techsupportforurm.com) already , are you trying for two out of two?

Your spelling is not impeccable either. oscaryu1 is a VIP Member here, which is earned by demonstrating maturity and ability/willingness to help. Whatever issues you two have from other forums please don't bring them here.

I would definately now recommend upgrading your PSU to a single rail quality unit such as the Corsair 620W / 750W. You can look at other units in my Power Supply Info link in my sig if you wish.

While it's possible for any individual rail to be overloaded in a multi-rail PSU, that is not the case here. If an individual rail is overloaded it trips OCP and the system shuts down immediately, it does not cause freezing or stability problems.

Regardless, the 12V rail is out of spec. This will cause a the gpu to overheat due to lack of power.

Quote:

If you wanted 100% conclusive approach, get a multimeter and test the 12V rail during load (e.g. 3DMark06)

That's going to be about the only way to confirm it. Software measurements are notoriously unreliable, and I sincerely doubt that these are accurate. If the +12V rail was really reading at 9.87V at what appears to be an idle measurement, he'd almost certainly be experiencing more serious problems than freezing after several hours of heavy gaming.

A low powered PSU definatley will cause overheat issues, so don't think this is a peripheral problem.

Nonetheless the provided temperatures are fine. Perhaps a reading under load would clarify things a little.

I'm running that ^ PSU with this card:

http://www.newegg.com/Product/Produc...82E16814127294

And a Celeron 420, 1.6GHz OC'd to 2.1GHz...

DVD Burner, a case fan, 2GB of memory...

And seeing that I played BF2, and BF2142 well with no artifacting or overheating...

And take in mind, a $15 PSU with a crappy manufacturer...

To be fair, a HD 3850 is in a whole different category with regards to power consumption than a 3870X2 and even with your system, I'd be a little worried about the long term implications of that, but the point is correct - the PSU in questions is quite sufficient for that system.

That PSU is rated for +12V@50A. That's ample power for the system in question, and as I've already said, this isn't a single rail vs multi rail issue. I'm certainly not ruling out a defective PSU, but there's no need for a more powerful one.

The voltage readings are of concern, and certainly merit further investigation. I would be interested to see what the BIOS reading is, but using a multimeter to check the rails is the only way to be sure, unless you can borrow another PSU for testing purposes.

What is the reason why I have that? What do I have to do? Buy a new PSU? If need new PSU' please link here (only on newegg). Thank you for helping me.
