Garbage psu? *PIC*

[shabby]

Here's a pic of my psu in action during this time im just surfing the web, barely any load on the cpu. And when there is load(prime95) the 12v rail goes as low as 11.4 volts :Q

Should i ditch this psu, its rated at 550watts and no its not a 10 dollar psu, its a good brand.

Rule #1.

Software readings for voltages and temps are wrong.

What brand is it exactly?

So my bios(software) is also wrong?

Wont say which brand yet, was some opinions first.

Use a meter to measure your voltages!

How can we help you if you dont even provide a make/model number or even the specs for +3.3v + 5v + 12v AMPS ???

Are we supposed to guess? :roll:

Watts don't mean jack! It's all about the QUALITY in the PSU, not the number slapped on the side that it got in some prime and specific conditions in the company's lab.

You can take any shoddy 550W PSU against a 350W quality one from PCP&C, Enermax, and some Antecs and it'll perform just as well.

F.uck you shabby, we dont play games, theirs a reason your not saying the brand so take the powmax psu and shove it.

 

[shabby]

Enermax 550watt psu, 40amps on 3.3v, 45amps on 5.0v and 25amps on the 12v rail. I have a gf6, 2 120mm fans and a dvd drive plugged into it.

"Oh no not enermax, thats impossible, its a good psu!"
I didnt mention the brand because i wanted to know what people thought of that 12v rail first, who cares what brand it is. If its a crappy psu you'll have a crappy rail, if its a solid psu you wont... right? Wrong.

ComatoseDelirium thanks for the kind words, "we dont play games" looks like you havent been here long enough kiddo.

That's weird that your +12v goes so low...

Just a question but you did connect the 4 pin 12v connector to your motherboard right?


If you're not crashing then I say just ignore it like ribbon13 said.

 

[shabby]

It goes even lower in this pic that spike at the end was under full load in prime.
Yes the 4pin connector is connected, you can kinda make it out in this pic, its at the bottom left of the heatsink fan.

I have a a64 3200 at work with a $20 psu and the 12v rail is solid at 12.1 volts, no spiking whatsoever. So i think im kinda screwed.

-/+5% is safe limits for the 12v range which mainly draws from the CPU and you seem to be within that...tack on some other 12v goodies and see what happens...if it remains the same then not to worry.

Hmm. Regardless of brand, given the specs of that PSU, and the apparent (mild) load on it, if the system in the picture is the system in question - I would call Enermax for an RMA. I know that software voltage monitors are rarely calibrated correctly, but they are useful for showing dynamic variances under load, and ... that's a lot of variance. Does the variance go away, when the PC is left completely idle? (Disable screensavers, etc.) If it does, then take a reading with a meter, on one of the molex leads or so. Use that offset to "virtually calibrate" what you are seeing on those readings, and use that info to see if the max/min readings during variance go out of spec.

Do you have another PSU to test with, to swap in and see if the Asus probe software shows a similar level of variance on the +12V line?

 

[Chaotic42]

My software numbers are way off. They say 11.7 on my 12V rail, but my multimeter says 12.1.

I have 7 Antec PSU's in the house on different motherboards. They all show different software readings, but with a VOM, they are all +- .05v of 12v Don't tell me its crap untill you have put a VOM on it....

Exactly and ASUS probe and BIOS has been known to be off on their readings. They have had to update BIOS's because of this often on their MoBo's

his computer would not boot if he didint have the 4pin conector.

 

[biostud]

stability is the key word here, if it runs stable don't bother.

they golden rule here with comps is......

If its not broken, DONT TRY AND FIX IT!! lol

Some boards boot without it connected,12v is very low but they still boot.

As others have said, software voltage readings (bios or otherwise) are almost always wrong and almost always on the low side. Get a meter and do it right.
. 12V being perfectly flat is unimportant as everything that actually uses the 12V rail either drops the voltage with its own regulators and filtering circuits or controls the end result with servos. As long as it doesn't drop much lower than spec (11.4V minimum) you're fine.
