PSU problem

[Lolcb]

Hi, I recently just bought the ETASIS ET-850W for my pc setup.

Lately I have been getting lockups etc in games and I was wondering if it is the PSU. Then I proceed on to check the +12v rails of my psu using everest and speedfan. Here are the following screenshots:



As you can see, my rail is way below 12V. Any ideas?

Hi, and I notice that everytime when I shut my comp down, I get this high pitch sound coming from the pc. I can confirm that it is the PSU's doing, because it is the only components I changed in my pc.

Any ideas?

Any help at all?

Any technician from scan able to determine this fault? I am not the only one, many others are having this problem with the Etasis PSU.

It is putting a near £2.5k PC at a risk here, I would appreciate help?

Speedfan isn't very accurate at reading the voltage rails, i'd check it in BIOS to be honest, or with an Electronic metre (Which can be purchased from electronics stores like Maplins for a fair price).

I do however agree, even with Speedfan getting it up to half a volt wrong in my experience, the difference from it being 12V is still a problem.. Try changing the software or reading it another way first before RMAing it.

I'd guess your PSU was faulty. There is no real way of knowing without using a multimeter, but I can't see Speedfan being THAT far out.

Do you mean 'withOUT' using a multimeter? Lol.
Because Professionals measure them using multi meters.
Anyway, I would RMA the PSU and either ask for a replacement or your money back. It doesn't appear fit for the use which it was sold for.

If it was a lower Watter PSU, then I would say you have just bought a too weak one for the application it was used. But nah.

does the low voltage reflect in the BIOS "hardware monitor"?

If so then i would as per the posts above register a Tech OLQ located here as the chances are that its faulty:

also in case the issue isnt the PSU where possible try to replace the PSU with perhaps a friends to see if the 12v line is still out, it seems odd that both the + and - 12v lines are out.

Ok, I will take a look at the BIOS. But unfortunately I just sold my previous PSU and now, I don't have a spare one to check.

By the way, I like your sig. What is wan ton? LOL

Wan ton = chinese dumpling that usually goes with noodle or comes along with a soup.

Why not? Of course it can be and certainly is.
For a start, if the 12V was only @9V the PC would be cut down dead anyway, so i'm sorry Robert, your info is wrong.
Not only that, but SF is also saying that the system temps are -65 degrees. Unless you use your PC outside at the North Pole or cooling with liquid nitrogen thats unlikely wouldnt you say?
ALL monitoring software is notoriously incorrect for measuring voltages <---fact.


The ONLY way of getting correct measurements is by a using DMM (multi-meter).

The PSU may well be faulty...thats a good possibility judging by the problems occuring. Its just that using software to determine it is most definitelty the wrong thing to do.

That's exactly what I meant. I made a typo as someone else in the thread pointed out

Yes I did mean "without"

went to hardware monitor, the 12v rail is 11.96.

Apparently my PSU is fine. everest/speed fan is crap tbh.

Thanks for the help once again scan.
