Quick question on the PC P&C 510

[wildc4rd]

Got a PC P&C 510 SLi from EP a few weeks ago, and have been monitoring the rails with a multimeter for a week or so. I have noticed the 12v rail 'creeping' up from cold.

If the rig is on for 12 hours or so, it will start at 12v exactly + or - 0.01volt, over the course of the 12 hours it will creep up to 12.50. Hardly threatening I know, but just wondered if it was a known problem, and if there is a fix for it.

I've never heard of that before! You would actually expect the opposite, as the PSU becomes warmer its efficiency under load would decrease, so it would drop the voltage, unless its a counter measure. Hmmm...

 

[wildc4rd]

Damn thing is still going up!

It definately shouldnt go that high, i would talk to phil about it if you got it from him, unless you specified a high 12V rail that shouldnt be like that and i think you should get a replacement from PCP&C.

mmmmmm - seems weird and certainly one that should be checked out, contact phil and let him know the problem you are exeriencing.

Could be nothing but best to air on the side of caution.

Looks like its hooked up to a molex, so that`ll be the real voltage. If its creeping up, that aint good, but could you try the volt adjustment pots to tune it down? It might be safest to take the PSU and trigger it by shorting the green and any black wire then tweaking to make sure you dont trim the wrong way. The ATX spec does not allow for voltage trimming to damage hardware through excessive voltage, but seeing as your voltage is increasing anyway, it might go past the safe limit.

Prob better sending it back though...better safe than sorry.

If its rising over a long period of times (ie 12 hours) lowering the rail manually wouldn't be a good idea surely kenny? As it would have to be put down to 11.?

 

[K404]

True, really not ideal. Would have to be a sweet-spot to make sure the PSU is still got enough of a potential difference to let the computer do its thing. Any trimming would only let the crepping number seem less....worrying.

It must be faulty and if it was me i would send it back i wouldn't want any of my gear being fried.

You shouldn't have to adjust rails RMA it mate,Phil does a nice 700w now!

Welcome to the 1% of people who receive a faulty PCP&C, it means we are special!

my PC P& C 510 gave out 11.71V initially.. but after adjusting the rails i got 11.97... doesnt go any higher than that though.... is 0.25V a maximum adjustment we can make on teh 12V rail??

Between its doesnt even budge .01V under load... Supreme quality and ensures in greater stability...

 

[maverik-sg1]

The pots are adjustable - read the manual and look to see how to do this, but double check the volts using a multimeter first as BIOS readings are just a rough guide.

If you are saying it wont go any higher than that - don't worry, 11.50v is still a rock solid stable line - 11.97v is actually very good. Stability is the key, you will only need to up those voltages if you get massive fluctuations.

the great thing is that i dont get any fluctuations.... but i think i have hit teh limit on teh pots... dont have a multimeter to check teh real voltages :/

 

[maverik-sg1]

Chances are the voltage are better than you think - dont panic - just enjoy .

[Dany]

yea i am really satisfied by it uptill now... thanx a lot for ur consolation

All part opf the EPUK experience

I have a confession to make.

Was running the rig on a spare PSU and decided to check the rails, funnily enough, the same creeping 12v rail.

You will notice in the photo of the multimeter that the low battery indicator is on, having the same thing happen on 2 different PSU's made me wonder, so changed the battery in the multimeter. The PSU never moves from 12.08 now.

*feels kind of stupid*

(will check it for a few days to be sure, but I think its a case of opperator error).

ROFL, someone forgot to change the batts in their multimeter, tut tut

 

[satman]

Seen it before.

The multimeter uses a stable supply to referance against.

When the battery is dying the voltage drops and the read voltage on the meter goes up.....
