bad problems with hiper hpu-4s730

[raikkonen]

hi guys,
my psu is 6 months old, and hiper is cracked...so no warranty...

the problem is:
i start the pc, everything goes fine.

then i start to play something.
5 to 30 minutes, and the pc restarts itself, no freezes, no strange images, just restart.

I tried with another psu(with much less power and quality) and it works fine.

I opened it, but everything seems fine, caps are teapo.

What should I do?Should I recap?
I have oscilloscopes, probes, everything, just tell me what to do, I want my psu back to work!
Thanks a lot in advance guys, and sorry for my english, I'm italian...

When it is running, check the temp coming out the back. It may have thermal shutdown.

Also, teapo is notorious for going bad without showing it.

Welcome Aboard!
"sorry for my english, I'm italian"
No worries, I'm American and I don't speak Italian one bit.
When you can, please update your profile to show your location.

>>hiper is cracked<<
What does this mean? That you opened it and broke the seal?

I Googled the unit. Impressive looking. I like the connectors, just not their position.

System Specifics Please -
- What is connected to it in your system?
- What brand & model of mobo
- CPU
- # of fans
- # of drives & types
- video card(s) & type
- are you overclocking?
- any other peripherals?

Have you contacted the manufacturer with the problem?

Could it be the motherboard? Certain P5xxx Asus boards do that with the higher end 115w Prescotts(?) 640-650-660.

How hot is the CPU when it shuts down? Do you have monitoring software that creates a temperature log file?

Have you removed the CPU HSF, cleaned it, and reapplied an excellent thermal compound -correctly-? Arctic Silver 5 or better such as Shin-Etsu X23-7783D.

It also be un-balanced loading of the rails. Need more info.

If you have opened the case, then post us back some info and some pics. We are a bunch voyeurs.

Re: bad problems with hiper hpu-4s730

ok, thanks guys.
first, my pc:

cpu intel e8400
mobo dfi x48 t3rs
ram: cellshock ddr3 1600 2x1gb cl7
hdd: 2x samsung spinpoint f1 320gb raid0
video: hd3870

there is a 20% OC on the cpu.

Well, with "hiper is cracked" i mean the company is "out of business", so my warranty has gone...

Temperatures: no problems at all, system is watercooled(cpu, nb, vga), temps are never over 30°C, i used everest to log them.

Case is always open...I will show you this evening if i can upload a couple of pics...

Fans, 2 nanoxia 120mm, 1 crappy 80mm.
There is also a swiftech mcp350 pump, it's a 7w pump connected to the 12v rail.

If you need more info, please ask, otherwise, remember that with a lower power cheaper psu, the pc works fine, so the psu is the problem from my side...

Re: bad problems with hiper hpu-4s730

You may be overloading one or more of the rails on the power supply. With multi-rail psu's I usually put the video card on it's own rail, typically the pci-connectors are on their own rail, the motherboard on it's own, the motherboard connector usually shares the rail with one of the rails for the molex/sata connectors. The cpu power connector usually has it's own rail, also can share the same rail as some molex/sata connectors too.

I don't know if the rails are labeled as to what cables they go to on this unit, but if it is it should be fairly straight forward.

Re: bad problems with hiper hpu-4s730

well, there are 4 lines 12V 18A, and double vga connector, it's quite hard from my side to overload them...
molex for the 2 sata drives and pump are separate, just to be sure...
damn, i need time to open it again and see the caps values...

Re: bad problems with hiper hpu-4s730

Hi Raikkonen,

My questions were aimed at exactly what 370forlife said; an unbalanced load on the rails. But, your explanation and list of components does not indicate that at all. Thanks for listing them!

I have read some other posts in other boards reporting the same problem you have. i.e.-system won't stay running with this PSU but, put a stock 350w unit in and it never has a problem.

I concur with your conclusion, that there is some issue with the PSU. It may or may not be a cap problem.

Please post pics of the PSU insides when you open it up. This is a rare PSU to see and I'm interested in how (well) it's put together. Hopefully it's internals are as good as its outside appearance would indicate.

Please list all the caps with the following info:
capacitance/voltage - diameter x height (in mm) - brand/series

Example: 1000/6.3 - 8x20 - Teapo/SC

[EDIT: Can you also measure each of the voltages and report those too? ]

Re: bad problems with hiper hpu-4s730

Yes mate, i just need an hour of free time to do the job, hope this evening, but who knows...
PSU is very crowded internally, full of coils and extra vertical boards with soic chips...it really scares me!i'm used to see few cheap chinese components...

Re: bad problems with hiper hpu-4s730

Remember when PSU is open and powered the heatsinks can be much more than line voltage.

Re: bad problems with hiper hpu-4s730

Hiper has been criticized for poor soldering work.

[raikkonen]

Re: bad problems with hiper hpu-4s730

This is true, the first thing i've done after opening was re-soldering, but it doesn't help...

Re: bad problems with hiper hpu-4s730

hi guys, here's very late, but output capacitors are 3300uf, 16V, 10mm x 30mm teapo electrolytics. Which kind of replacement can I use?I think there's no panasonic fc with these dimensions...

Re: bad problems with hiper hpu-4s730

I once had a PSU would not self-start at all, no shorts or open circuits years ago when I checked all over even I tried or probably mis-remembered changing ICs in a AT SMPS (same size as current SMPS cases). That what stuck in my mind about it and what I remembered is back then I did not have ESR meter. Now, I don't have SMPS anymore. Pitched it long ago.

Cheers, Wizard

Re: bad problems with hiper hpu-4s730

Teapo usually last in PSU's. Sure they need changed?
FC isn't good enough for main OP filters anyway.

Only [available & probably reliable] 10mm 16v 3300uF I know of is Samxon RS series.
Any other 'good' brands only have them in 12.5mm and up.
Those Saxon RS are a custom ordered size but this site sells them if you are in the US or Canada and outside the US/Canada this member sells them.

Re: bad problems with hiper hpu-4s730

well guys, i really don't know if they need to be changed.
I simply know that electrolytic caps are one of the main fail on atx psu, so i want to try to change them.
Moreover, I've heard teapos tend to dry without showing any sign.
If you have any ideas about how to test the caps or about how to test the psu(and know where is located the damage), this will be very helpful for me!

Re: bad problems with hiper hpu-4s730

Unlikely to be the PSU at fault - could be, but more likely it's a driver issue. Depending on what OS this is, you need to disable restart on system failure so you can actually see the bluescreen you currently cannot because of the instant restarting.

mate,
there is no more issue when i swap the psu with another one...

Per favore inserisci la tua fotos.

How was that??

Re: bad problems with hiper hpu-4s730

hey toasty, are you learning italian language?
sorry but i haven't taken pictures yet...
i'll do it, this weekend i'm completely free...
ok, i've taken out the three 3300uf caps, measured:
1) 3300uf
2) 3300uf
3) 3200uf

Well, a friend told me can be tolerance, but it's not strange that only one cap has lower capacitance?
Do you think i should change them?
I've contacted Joe for the caps right now...
