my psu exploded!!

[Ish]

i always used to buy cheapo PSU's until reading advice from OCUK. I would never take the risk of a cheap psu taking out other components again but I would never shell out for a top end one as the prices of those are just mental

 

[Joe42]

A Hiper psu blew up the TrustedReviews test station when they tested it and none of the other 20 or so did. And there was a spate of failures reported on here not long ago.

But its not that which concerns me, its the fact that almost all failures reported resulted in damage to the components connected to it, whereas failures of psu's made by the more respected manufacturers did not.

Apart from that, its a poor design as its noisy and exhausts hot air back into the system.

All things considered a better psu can be had for the same price and i can't recommend a psu which has a tendancy to blow things up.

I had a q-tec once, obviously it decided it didn't want to live anymore and went kaput. It blew one of the capacitors off the mobo when it went, and to this day I still don't know where that capacitor went. Unless the PSU formed some sort of black hole when it blew and sucked it in.

Just thinking on this, it'd be the perfect form of sabotage - get an agent to act as a computer tech, and replace the enemies PSU's with Q-tec ones. Then it's just a matter of time..

There are many of these so called 'agents' acting as computer techs in local pc shops and in purple shirts throught the country. They regularly put cheap psus in powerful systems and destroy them.

I prefer to just flick the old '240/110' switch over to 110...

I'm still trying to convince a friend that the company he works for using Qtec for their system builds is a very bad idea, he's still adamant they work fine and do not blow up.

He says he's not had one blow yet.

Personally i would'nt knowingly put in such a terrible piece of hardware into systems i was building for sale.

 

[Joe42]

Its not such a problem if they are low end low power systems, its the high power expensive gaming systems with with cheap psu's such as Q-tecs which are the problem.

I admit i have a couple of no name psu's powering really old systems and they do fine. Its the people who put them in gaming systems that are asking for trouble.

 

[t31os]

They never mentioned ever using any other brands, so i'm pretty sure they were fitting them in all the systems they worked on and built, though i could be wrong, but was convinced theres nout wrong with a QTEC.

Typo in last message, he doesnt actually work for them now, he's moved somewhere else, i just hope someone at the new place can show him the light..

I can't say i like Qtec's personally, for starters no O/I switch on the back, thats a recipe for disaster if the owner goes to add a new stick of ram etc.....

Unfortunately 1 PC here has a Qtec, its the old girls PC and she hates the PC being down for long, so it was the quickest thing we could find from a retail shop unfortuntely without going into silly prices. I'm the one who goes inside her case though, and like you said its a lower spec system, so not seen any problems yet, but if it comes round to upgrading, that piece of crap can join the rest of the junk in the trash, just not worth the risk of the other components.

We has a enermax liberty 620w go bang the other day... Was loud as hell and accompanied by loads of bright blue sparks...

 

[Joe42]

Did it kill any of the stuff attached to it?

Oh No , Not the Anti - Hiper post's again !

I'm sure Hiper will admit they don't have a 0% failure rate , along with all PSU manufacturers.

I have a Hiper 580watt which has served me faultlessly.

I find your quote :

" Apart from that, its a poor design as its noisy and exhausts hot air back into the system. " Ridiculous.

Is this from personal experience or just gossip ?

Do you honestly think Hiper would be selling these PSU's if your quote was fact !

As posted above an Enermax liberty just went bang , Do you add this to your list of "poorly designed" PSU's ?

Cheers,

Mark

" Apart from that, its a poor design as its noisy and exhausts hot air back into the system. " Ridiculous.

-Its noisy.

It's by no means silent

This is relative to proper psu's such as Seasonic.

-It exhausts hot air back into the case.

Rather unusually three of the sides, but not the rear, are constructed out of a metal mesh, which we couldn’t quite see the reason for. The idea is to reduce the forced air cooling effect and allow for better heat dissipation, but this way you would get the hot air blown back inside the case, which isn’t desirable.

-It has an unusally high failure rate.
-It tends to kill other components where other psu's do not.

There have been many threads like this, this and this.
I agree, even good psu's fail on occasion. The problem with these is more seem to fail than other makes, and those that do seem to cause damage to components. As i don't have conclusive evidence for this one, you can ignore it, but the rest of my points should be condemning enough.

-It blew up the Trusted reviews test kit.

At this stage we thought it was the test equipment that had failed, but plugging the Type R back in after the equipment had been fixed showed up a grounding fault in the PSU.

-It doesn't provide its rated power

More worryingly this was only at 436W, not even close to the rated 580W.

-Its expensive considering the above.

Oh No , Not the Anti - Hiper post's again !

No worse than the anti Q-tec posts. Same message.

Is this from personal experience or just gossip ?

Wouldn't catch me buying one. Any of the above points would be enough to put me off. This is from many threads and many reviews and many people having problems with them.

Do you honestly think Hiper would be selling these PSU's if your quote was fact !

Hundreds of cheap psu manufacturers sell massive quantities of psus. Doesn't stop them selling rubbish, doesn't stop fools buying it.

As posted above an Enermax liberty just went bang , Do you add this to your list of "poorly designed" PSU's ?

No, i expect the system it was connected to still works.

I have a Hiper 580watt which has served me faultlessly.

Ohh thats alright then, i'll go and buy one now. You were accusing me of basing my facts on gossip?

 

[KizZ]

My Hiper has worked great during the past 6 months. But recently when the heat kicked in the 80mm fan at the back started to rattle a bit. Im a bit unsure what to do now . I might RMA it.

 

[tim_enchanter]

/\ Sure I just read that post somewhere else

 

[Brizzles]

I accept your comments , but The Trusted Reviews PSU failed due to an individual grounding problem within the test PSU.

PC Apex - review of the Hiper Type R 580w ;

http://reviews.pimprig.com/power_supply/hiper_type-r_580w_psu_-_us_version.php?page=3

Now I wanted to check the effectiveness of the perforated sides and top. I taped a temperature probe in the center of the PSU and another to the exhaust fan took a reading with the sides and top uncovered. Then I grabbed some masking tape and plastic and sealed the sides and top. I ran it each way for another 30 minutes. With the PSU not sealed I received a reading of 52C inside and 29C at the exhaust. With the sides and top sealed it read 49C inside at 30C at the exhaust. Really too close to make a call either way on which is better.

Conclusion :

Good
- Modular design
- Aviation style connectors
- Nicely braided and flexible cables
- Great finish on exterior
- The PSU container is original and functional
- Solid voltages
- Quiet operation



I apologise for suggesting you based your decision on "gossip" it was worded wrongly, but 2 different reviews and 2 totally different results.

I guess it depends which review you read !

Cheers,

Mark

Group-hug!

 

[Joe42]

Fair point.
Although i would say it depends on which review you trust...

The Pimprig test looks like they were testing the effect of the perforated sides on the internal temperature of the psu. I was saying that the problem is they increase the case temperature because hot air from inside the psu passes out into the case rather than out of the case. The review actually proves my point, the internal temperature of the psu went down with the perforated sides uncovered. But the exhaust temperature didn't really change, so where did the extra heat go? Into the case.

At this stage we thought it was the test equipment that had failed, but plugging the Type R back in after the equipment had been fixed showed up a grounding fault in the PSU.

I got the impression they were refering to the Hiper type R not the test equipment. Link

If it is silent, then overall the design isn't too bad apart from the perforated edges. however a psu which failed to deliver its rated wattage is unacceptable. The Seasonic S12-430 430w is more powerfull than this 580w psu, and i know that Seasonics will work quite a bit above their rated wattage.

Considering the Type-r costs £64 and the Seasonic S12 430 costs £52 and is considerably better in all respects except modularity i can't see any reason to buy this psu myself.
