What is the main cause for psu going FUBAR and taking out the motherboard with them. I was under the impression that even a cheap psu should be good as long as you don't have a system that is that power hungry and demands alot.
 
The main cause for PSU failure is component failure. This can be due to poor voltage regulation, defective components, or components being stressed past their tolerance. All of these things are more common in cheaper PSUs, because they use lower-quality components which means that they can't handle as much as a better PSU would. Regardless of power demands, a high quality PSU is always much more reliable than a cheap one.
 
is there anyway to properly check the voltage that the psu is actually putting out, i recalled reading somewhere that people were able to registers fluctuations in the power that the psu provided.
 
The only way to properly check voltages is with a multimeter. For testing more in-depth stuff like ripple and transience, you need special equipment.

Yeah unfortunately that's false. You and I have both learned the hard way that cheap PSUs are more than capable of killing hardware even if you have a light load on them.
 
You get what you pay for.

I've had many crap PSU's and only 2 high quality ones. The only ones that still work are the quality ones, and really a quality PSU won't cost that much more, it all depends on what your doing.
 
i had like 2 or 3 PSU failed and went into smoke before. None of them took out my motherboard along with it. All PSUs will failed eventually, a quality one should not take out the motherboard or other devices when it fails. imo, paying more money for a quality psu does not guarantee operation duration, it should prevent collateral damage when it fails.
 
Actually some good brand name 1000watt psus are very shit...but when they deliever power they deliver it but not a 80% good delieverance

Good brand name such as? All the better 1000W PSUs out there can cope with a full load at 80% efficiency or higher. Any ones that can't aren't "good brand names".

To us, the PSU informed, yes those that can't are not "good brand names". Unfortunately there are PSU brands out there that many people (the uninformed) still think are good 100% of the time like FSP and OCZ. Both companies have had 1000W PSUs that fail testing:
- FSP Everest 1010W
- OCZ GameXStream 1010W

Hell even BFG had a bad 1000W PSU:
BFG Tech BFGR1000WPSU Power Supply

So basically my whole point: There are some "good" (to the misinformed enthusiast) brand companies that makes crap 1000W PSUs.

Thank you Danny thats exactly what I meant..and that has just answered the person question the above.
 
i personally have a Corsair 750TX. Currently my sister enlisted me to build a computer for her and shit insist on using the power supply that was supplied by the barebones kit. I read the reviews on the case/psu and almost half of the people there stated that their psu failed them. I was wondering if there is any way i can test the powersupply. I was planning to hook it up to an old system and just run prime95 for like 24hrs. Hoping that if anything goes wrong it would only take out my old system.

My point though is that I wouldn't consider a brand that puts out shitty PSUs as a good brand name. Brands like OCZ that may have good products in other categories but make poor-quality PSUs should not be considered as good brand names when it comes to power supplies.

Gotcha
 
As far as I'm concerned...I don't think their is any shit quality 1000 psu's out there, yes by that I mean those unknown and weird brand names. I'm gonna get a 850watt PSU soon and its not a popular brand (better then generic I think) and it looks nice and all coated in silver and got good amps for each of the diff rail volts, heck it will only cost me $100. Not bad...and if your gonna get a 1000watt one..I doubt it, it will be a piece of shit like those shitty ass generic 300watt ones.

You'd be surprised at the number of shitty high-wattage PSUs out there. The FSP 1010W Epsilon that Danny mentioned earlier is a good example, as is the Coolmax 950W from a few months back which is basically a tremendously overrated 600W unit.
 
Yeah those are just overrated ones. This one I'm buying looks legit enough to me that it will be able to handle my future Matx crossfire setup.
 
Ok, now I'm curious: What PSU are you buying, Matthew Kane?
 
He'll learn his lesson once one of those things takes out a computer, I sure did.
Looks legit and legit are two VERY different things.:rolleyes:
There are definitely shit quality 1Kw PSUs out there, Coolmax, OCZ, FSP are all terrible PSUs while on the other hand you have the Corsair HX1000, Toughpower 1200w, PC Power & Cooling 1Kw and Cooler Master UCP 1.1Kw. All of these are 1000% better than the the former ones.
 
Mr. Kane really is misinformed, I'd suggest anyone trying to educate themselves on this subject ignore his "input" if you can even call it that. Anyone can rate their PSU at 1000 watts. All it takes is some ink on the box with the digites "1000" Actually being able to reliably output 1000 watts takes quite a bit more effort. Bottom line, not all PSU's are created equal, even ones rated at 1KW

I've always put high quality PSU's in my main rigs and have never had a problem related to power. I built another box out of all spare parts as a folding only machine that I put a cheap PSU in there. It worked fine for the time I used it but the exhaust sure did get hot. I would always shut the computer down when I left the house becuase quite frankly, I didn't trust the thing not to burn down the house. I eventually replaced the PSU in my main machne with a Corsair and put my Enermax in the folding box and have MUCH more piece of mind. I no longer have a fear of my house burning down if I leave the PC on.
 
I actually had a Raidmax 450w (you know the ones that come with their cases) burst into flame and then explode. Luckily even as a n00bie I wasn't stupid enough to buy one but my friend did and he insisted the same thing that Mr. Kane is.
 
I'm suprised that none of you got it... The REAL reason that PSU's die is because the magical blue smoke gets let out.

you trying to call me stupid there hey?
 
We are not calling you stupid, we're telling you that your WRONG.
If I wanted to call you stupid I would just go "Your stupid" but I'm not since there is not point in insulting someone as it's not constructive to the argument. We're trying to tell you "Hey, that's not a a good idea and multiple website have proven that there are differences"
Finally, if you want to back up your side of the argument, spend time finding links to sites that support you instead of telling RamonGTP to go jump off a cliff.

@BuBBa = Of course, everybody knows that. :D

Since everyone else seems to be in a pissing contest at the moment, I'll try to offer some advice based on my experience. "Never, ever, ever use the PSU that comes with a case or barebones system." * You will regret it. I built my sister a computer several years ago that came with a 500watt PSU. All she has was a SiS chipset video, Sempron 2300+, 512MB DDR, an 80GB hard drive, and a DVD-RW drive. The PSU literally popped after 3 months.


* NOTE: This doesn't necessarily apply if it's a combo deal with a top quality PSU.

The question is, which PSU's are best at blocking the little blue demons that sneak in and let that smoke out? And why are they attracted more to some PSU's more than others?

I have, it was a blast.

No need to get upset, it was you afterall who was giving the shitty advise.
Click to expand...

I wasn't giving any advice you tard. I was just making a statement of my own that I don't there is shitty 1000psus (desipite me making a post about it, but I wasnt too sure). Well sorry, but I have a life and not like you who spend your life in front of reviews and results and just seeing which psu's work best. I wasn't telling the op to get a frkn generic brand psu, now was I? No I wasn't...I just never knew their was shitty 1000psu's. And about my own post that I made about the psu I was planning to get..it turned out to be a OCZ, like such as I posted above in reponse to danny's question. Now read the whole thread thoroughly next time before you make another stupid response as you did such before and misunderstanding people.

Yes I know what you mean for the psu part, but I just never knew that $250+ psu's can work real shitty. The only reason I told RamonGTP to jump off a cliff...coz the airhead didn't properly read my previous post and saying that what I stated for myself and others have corrected me later, mentioned that I was giving stupid advice which I wasn't...just I didn't know psu's like some of the 1000watt psu's are shitty (danny corrected me more on it).
 
Dead thread. The name calling is out of line, and for those of you that are going to try this stunt again in the future, the original post gets recorded so we can see it even if you edit it.
