PSU tier list 2.0

[Someone Somewhere]

Bad bearings in fans is a common one. Also, anything that can get caught in the fan eventually will.

Parts that aren't heatsinked or don't have enough heatsinking, or are underspecced. Sure, they'll work for a while, but they'll probably burn out eventually. Bridge rectifiers are a common example.

Poor component placement can make the caps run much hotter than otherwise. On the flip side, putting caps on the modular connector board is probably fine because they won't get hot, so they don't need to be as high quality.

Lack of mechanical protection where the cable goes through the case can cause chafing.

Poor soldering can also cause longevity issues.

If hundreds of users complaining that they've all had the same type of failure with the exact same units isn't reliable enough information to form a general reliability opinion on, then I don't know what is. A sample of one or tens, no, a sample of hundreds, has to mean something is going on.

If you've never seen a review that has indicated how poorly the fan used on that model is, or that the unreliability of a sleeve type bearing fan was the reason they took points off, then you haven't read nearly as many reviews as you'd like to believe. I've seen numerous reviews of that nature and others indicating that crappy diodes or rectifiers were used. There are a lot of things in a unit including tiny not-up-to-the-task heatsinks get nixed in reviews as well. Those are all things that affect long term reliability and need to be considered in any review. Just slapping all Japanese caps in a power supply and making sure it stays within specs on initial testing does not mean it's a worthwhile unit for the long term.

It's true enough that the majority of units that meet that criteria will be, because few manufacturers would waste the time and money involved with doing that if they were going to crap out in other areas, but it happens in some cases.

I actually do take into account the fan bearing, as a matter of fact. I forgot to list that. And those folks on Jonnyguru forums are hypocrites. First the one user says on one forum thread that he considers Capxon "shit". Then, they all talk crap on me for considering the fact that the G2 had those Capxon parts. And OklahomaWolf himself scored against those.

It must be my name. Nobody can take someone named "turkey3_scratch" seriously. I knew I should have named myself Gwiddle...

Capxon is a brand. They have more than one line of caps, and the positioning in the unit can have a serious effect too.

 

[Karadjgne]

Sleeve bearing fans work great. Vertically, where the sleeve is positioned above the entire length of the pin. Horizontal, the pin rests on whatever cap, or none, is at the tip of the sleeve, so the sleeve does almost nothing. Double ball bearing and hydro bearing are much better at horizontal applications. Wonder when psu manufacturers will bother to quit using sleeve fans

 

[Darkbreeze]

Anything that cuts costs will continue to see usage for the foreseeable future. Unfortunately. I guess they figure if we save one dollar per unit, and sell 1000 units, then we make an extra 1000 dollars, rather than, if we pay an extra dollar per unit, get better reviews and quieter operation, we'll sell 500 units more with a net profit that's much larger than the 1000 dollars they saved on using an inferior part. Unfortunately, shareholders and board members don't always see things that way during the design and manufacturing discussions I guess.

 

[Karadjgne]

And the kicker is, I'd not even know in the slightest if a units price was raised $2. Or even care. $1 for the better fan, $1 extra profit.

 

[Darkbreeze]

Exactly. I agree. If I KNOW I'm getting better internal components for a minimal additional investment, I'd gladly pay an extra 5 bucks for a fan bearing I'd know was going to last twice as long or would be 30% quieter. Or an extra 2 bucks per cap to know that they'll all be top shelf rather than only on the primary side. What's sad is that recently, even on high end hardware, they are using lower end components because "it doesn't affect reliability". BS. It does. I don't care where the cap or other component is located or on which board, if it's lower quality, it's lower quality. It may not CAUSE it to fail sooner, but it won't LAST as long as a higher quality component. That's WHY they're higher quality components, they last longer or offer some kind of additional benefit.

If it costs you 2 bucks more per cap to not use cheaper versions, then charge for it, but TELL me that you've done this so I know WHY I'm paying that price and leave me no doubt as to whether or not you've skimped inside my power supply so that I have to find out later that what I thought was a flagship product is actually being manufactured by some farmed out vendor and that they are NOT using the same procedures and component selection that the platform is known for.


Sorry, rant over.

 

[Karadjgne]

Lol. But thats exactly the argument. If those CapXon caps see so little abuse that they'll only last 10 yrs before failing, in a psu with Japanese primaries that see so much abuse they'll only last 10 yrs, why spend extra to put higher priced Japanese caps in non essential areas, just to have them last 15 yrs? Does it really matter which cap fails after 10 yrs?

 

[Someone Somewhere]

Or an extra 2 bucks per cap to know that they'll all be top shelf rather than only on the primary side.

2 bucks a cap times twenty caps... on a PSU that may have only been $60 to begin with. I don't think it would cost that much, though.

In line with what karadjgne said, having 'high quality' everywhere may be more expensive and still fail sooner than having 'very high quality' on a handful of caps and 'medium quality' on the others.

 

[Karadjgne]

Yeah, retail prices on a single cap of the sizes used in a psu can range from 10¢ to $3. What Seasonic or FSP or SuperFlower pays for a million units at bulk rates is closer to 1/100¢ to 10¢ and they'll order a dozen different sizes at a time. So price for them in the 100 or so caps in a high quality psu is honestly negligible and easily absorbed by the consumer. The OEM will charge more per cap for the low end psus simply because there is only 20 caps in the whole unit and they'll have to cover production costs etc. It's only when you get a super-seller like the CX series that units will end up paying the same or less per cap as a higher quality psu, simply due to the sheer amount of psus ordered at any given time. The above mentioned Aerocool unit doesn't have the numbers of the cx430 in sales, so price per unit goes up by OEM because of retools, special order parts etc. It's the only way for the OEM to make money, which gets passed on to 3rd party who Jacks the price for retail, so we as the consumer see a $60 piece of junk vrs a considerably higher quality cx600 for $50

 

[Darkbreeze]

I was just being figurative with the amounts, not literal. Of course I have no idea what these manufacturers pay for components they buy in lots of thousands, but I'm sure it's much less than we could buy a replacement component for by far.

I don't think it matters where the inferior cap is used, it still poses a greater failure risk. It's like only using high end valve springs on a cylinder head exhaust valve. Sure, the exhaust valve's have a much higher failure rate on springs because they get hotter, but on cylinder heads that cheap out on the intake valve springs, they tend to have an increased failure rate on the intake valves even though they are NOT subjected to the same heat as the exhaust valve train. I guess this could be different, but I prefer to see quality across the board. If it made no difference, they wouldn't do it on these other high end models.

i use this as the bible for my builds thanks mate

Can someone tell me is nJoy 500wgx psu any good?I bought it a week ago and i want to use it with R9 270x im on low budget so i had to buy it, i just want to use it with R9 270x A8 5500(will upgrade to 860k in future if this psu can handle it) and 8gb of ram, can someone just tell me if its gonna be ok to have these specs with this psu?

Trash. It is only a 380w unit. Don't even bother connecting this to the PC. Just return it. nJoy seem to have a mix of low quality and junk units. Avoid.

And it has to be done on a pc, mobile app doesn't have the option

Probably blown a cap and then pulled too much watts and tripped everything.

I found that out, but my mistake is i didnt watched the reviews and stuff like that on web before i go to shop, and i bought that psu and the man who sell me that psu said its good, but my question is if i can run the R9 270x, i really cant change the psu now so maybe i will do it in a few months or so, but i just want to know if it can hold the R9 270x and pls tell me that..It is silent and its design is awesome and everything but my mistake is that i didnt ask other people how is their experience and stuff like that..So pls tell me if it can run R9 270x that is my only question here 😀

The wattage alone will be barely enough to run the system, as stated it's actually only a 380 watt PSU... even though it states 500 w.

I would take the advise of many of the veterans, including tiny voices, on the subject of what really bad PSU consists of... there are unfortunately tons of crappy ones out there. You may even have to worry about it frying your complete system under even moderate load.

Take caution.

Can you return the unit?
