3.3v, 5v, 12v, all low readings.

dragonoidso · May 5, 2016

In the recent months, my PC has been shutting down each time I play my games.

My games:
Dark Souls
CS:GO
Witcher 3

etc.
---------------------------------------------------------------------------------------------------------------------------
It shuts down completely after a couple of minutes.
Shut downs don't happen when I just browse the internet.

The temps don't get hot because I can only play for a couple of minutes before a complete shut-down.

---------------------------------------------------------------------------------------------------------------------------

I have recently added another 4gb ram stick and bought a new PSU. All in all, I have 8 gb of ram.
I've brought it to the computer shop for repairs, but they said that it just needed cleaning.
---------------------------------------------------------------------------------------------------------------------------

Now, I'm here to show all of you how low my V readings are.

Check this out:

Can anyone help me out here?
Thanks in advance.

You have a bad PSU. Time to RMA it if you can. I'm not sure what brand your using but some are just cheap to start with.

Dark Lord of Tech · May 5, 2016

Your PC wouldn't even run if those were right , HWMONITOR is junk.

Try AIDA64 or HWINFO.

I seriously doubt your PC would boot with every rail being off by 33%. Either the system monitoring chip is busted or the PSU is putting out enough noise that the system monitoring chip is misreading voltages.

What's the PSU brand and model? If you see it in tiers four or five below, you may want to replace it - your PSU is likely dying and may be damaging your PC.

Ive seen it that off before and working. Its a low power CPU and it crashes under any load. Bad PSU.

Shaun o · May 5, 2016

Well the power supply you have is not doing its job.

On any of the power rails you should only ever see a 10% plus or minus voltage difference in variance in power fluctuation.
8 volts on the 12v power rail is way below that tolerance.

You either have a power supply that is very old, or it is of a low wattage output and has been put under a lot of stress due to High power draw from it.

Or it is a very cheap PSU in the system that came with it, or the tower you bought.

The answer is simple, buy another one with a higher wattage rating and make sure that the amp rating for the 12v power rail is quiet high.

If the power supply is a cheap one with a little known brand name.

I suggest you look at one with a good known brand name for reliability.

Bellow is a link to some good quality branded power supplies.
You will note that as well as the wattage the amp ratings are of a high value for the 12v power rail, or rails, and the 5v and 3.3v rails.

If you compare this to the one you have in your system by looking at the side off the power supply unit with the side of the case off you will notice the difference.

A power supply is, the heart of your system, and though you might begrudge the price asked for a well known brand name and the wattage it can provide.
You get the added security of electrical circuit protection features in well branded power supplies.
Buying a cheap power supply never pays dividends in the long run.

For peace of mind and protection and reliability always pay the extra for a branded power supply.
I cannot stress this enough, because if a cheap power supply pops there is more of a likely hood that when it does it will also take some of the other system components with it.

Were a quality power supply will protect the other parts and components because it has protection circuit to guard against damage to any other components.

And why you pay the extra for one.

I apologize for the late post.

Is it just the PSU, or is the MOBO included?

dragonoidso · May 6, 2016

My PSU is quite new, in fact, I just bought it yesterday.

Shaun o · May 6, 2016

Pray tell all dragonoidso,

What brand name is the PSU, and it`s wattage.
And what does it say the maximum amount of amps from the 12v power rail, or rails can the power supply unit provide.

Open up the case and have a quick peek at the label on the Psu on the side.
Out of pure Interest, it`s a good indicator of how good the Psu really is.

A good give away is if it says made in china.
And you played about £35 to £40 and it claims it can do 700w.

HWINFO

dragonoidso · May 6, 2016

I forgot to mention that my pc has no beeps whatsoever when it turns on.

dragonoidso · May 6, 2016

Shaun o :

Hold on, I'll check.

I think it's a cougar.
I heard it gives 650 watts.

InvalidError · May 6, 2016

Shaun o :

That's not really a good indicator since many PSU ODMs design their PSUs in Europe, USA and elsewhere but get them manufactured in China too. Seasonic is regarded as one of the best PSU ODMs in the world and most of their PSUs including their high-end 80+ Platinum models are manufactured in China.

The Chinese manufacturers will manufacture stuff to whatever specs the client requires. What you need to be more wary of is Chinese-branded PSUs, knock-off brands and better-known brands who rebadge dodgy (mostly Chinese) designs.

madmatt30 · May 6, 2016

As has been said the PSU wouldn't even boot with the 12v rail only hitting 8v - that's a 100% fact

Boot to bios, there should be a voltage readout table somewhere in there.

Or use the monitoring software that came with your board.should be gigabyte easytune I would think.

3rd party software is notoriously inaccurate on fm2/+ boards.

Even the low end cougars are at worst average quality hec units , they're not great but hardly dire , very very unlikely the voltages are that bad unless its a cometelt faulty unit.

Did these shutdowns occur with the old PSU too ??

dragonoidso · May 6, 2016

Oops, made a mistake!
Actually, I bought a new UPS instead of an PSU!
Right now, I'm still using the cougar PSU.

dragonoidso · May 6, 2016

Guys I just found out about my cpu overheating to about a 113c!
Checked the BIOS and the results of the PSU was pretty good.

I think the problem here is the cpu...

madmatt30 · May 6, 2016

Download amd overdrive
http://www.amd.com/en-us/innovations/software-technologies/technologies-gaming/over-drive

Download Intel burn test

http://www.majorgeeks.com/files/details/intelburntest.html

Install & run and overdrive , open the CPU status tab

At idle the thermal margin should be 35-45c

Run Intel burn test & click the start button.
Leave it 2 minutes & let us know the lowest the thermal margin hits.

You can click the stop button in burn test to stop the test.

madmatt30 · May 6, 2016

What ups did you buy?? If its not up to par power wise it may be at fault.

dragonoidso · May 6, 2016

madmatt30 :

Madmatt, my UPS is an APC.
But right now, I'm plugging my pc straight to the outlet.
So far, it's been doing good.
I just turned off the fan control and CPU overdrive and right now the PC does not shutdown when I play my games.

dragonoidso · May 6, 2016

madmatt30 :

I'll try the AMD one

3.3v, 5v, 12v, all low readings.
