Why do so many seem to hate Rosewill PSUs

Hey all. Just general cusiosity, it seems like many people seem to hate Rosewill power supplies. I sometimes see people react to a Rosewill as if its some sort of computer antichrist. From what I've looked into them on Newegg like anything there are some cheapies but there appear to be some decent quality ones. Customer reviews seem good too. I understand there are brands people will recomend over all others such as OCZ, yet I've read many accounts of an OCZ failing. Obviously any PSU can fail. So what gives? Why the hate for Rosewill?

OCZ can be good or terrible, depending on how much you spend on their PSUs.

We hate Rosewill because Rosewill has only made ONE decent PSU, the rest are basically rigged to explode. This is why you don't go cheap on a PSU:

I wouldn't say they're rigged to explode. Most people will buy a power supply like that and never have problems with it. Duds happen even with the very best PSUs... (hey, like the last unit I bought <_< )

The Corsair video seems a little suspect to me. They were probably stressing a particular rail and trying to make the power supply fail. I'm sure their own products are built to take that kind of stress, but you can't really expect the budget power supplies to hold up in unrealistic operating conditions.

I'm not saying buy cheap PSUs... I just think most on the market are not so bad for 90% of consumer applications.

Oh, and Rosewill is Newegg's house brand.

They are not the worst PSU´s but there are so many other makers that have better reputation and are in the same price range that nobody is going to recommend them. It would be like recommending Dynex which is Best Buy´s house brand.

I bought a Rosewill, I know I know I should have done my research first etc etc. I went with it because it seemed to offer a lot, 4 12v rail 80 plus certified. It had been $200 one night, so I wasn't going to buy it. Next day it's half price for black Friday. I figure what the hell, I'll give it a shot. I can't say I've been dissapointed with it. Seems to run cool, not too loud even with it's large fan. My favorite feature is that the fan stays on for another minute or so after shutting down my comp, allowing for extra cooling. Had I been smarter about it and not jumped the gun at seeing what I though wasan excellent deal, I probably would have skipped it. Only time will tell though, I could eventually have problems with it but then again I could not. There's worse that could happen in life than my computer exploding. Lol

They are just generally poorer quality components. They are not a death sentence, they just have a higher risk of failure.

Regardless of the load you put on it, a PSU should NEVER explode. If overloaded, a good quality PSU will shut down, undamaged and without ever going out of spec on any rail.

Why do you disagree? Corsair makes excellent PSUs (I have an HX1000). There are other companies making excellent PSUs too (Seasonic and Antec spring to mind, among others), but Corsair is one of the few brands I know of where you can rely on every single PSU in their line to perform excellently.

I know that Corsair PSUs are great, but not the best. They are just too damn overhyped. They are like PC POWER & COOLING and Seasonic, who makes the PSUs, in that you can always trust them to be excellent. Best, they are not however. Out of the three I listed Corsair is likely the worst, but we are still comparing excellent vs. excellent PSUs. There is no best, it all depends on how much you want to spend and how much power you need. For example, the Enermax Revolution 1050w PSUs is the highest performig 1kw PSU to date. I love
Corsair PSUs, but they are called the best far too much around here.

That is horrible luck. I've had some bad luck with PSUs myself which is why I am so critical and picky about them. Luckily PC POWER & COOLING tests every single PSU shipped and includes the results, makes it difficult to get a DOA one.

Honestly, the best current PSUs for high power systems IMHO are the Corsair HX-850W and the Antec Signature 850. They are essentially unmatched for low ripple, efficiency, and general performance (unless you desperately need the higher output of a 1000+W). I'll agree that Corsair isn't the only excellent choice, but they make amazing power supplies (and the HX850 is incredible).

The Seasonic M12D and the Antec Signature 850w are a good deal better than the HX-850w, though it is an amazing power supply.

I really don't see how you're claiming that they're a good deal better - all the tests I've seen put the Signature and the HX-850 on roughly even footing. I'd forgotten about the M12D though - that's an excellent PSU as well (though it has somewhat higher ripple at full load than either the Signature or HX-850).

They're all better than some of corsair's older designs though.

Which ones are you looking at?

The JonnyGuru reviews show the M12D as worse than the HX - here is the 12V ripple at full load:

M12D: ~40mv
Corsair: 24mv
Antec: 13mv

As for efficiency, the Antec hovers around 85%, the Corsair around 88%, and the M12D around 86-87%. Honestly, although the Antec is lower ripple, I'd say overall, the Corsair is a strong contender for the top honors here.

http://www.corsair.com/cinema/movie.aspx?id=622747




Ok.. I'm bringing this old thread up again because of a glaring misrepresentation of Rosewill power supplies.

First off... the power supply in that video is not a Rosewill. It has been confirmed long ago that it is a Raidmax RX-450K 450W power supply.

Here is a link to the power supply, still being sold on Newegg.

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

That power supply is made by Sun Pro Electronics Company LTD. Which does not , by the way, make any power supplies for Rosewill.

Rosewill is Newegg's house brand and, as of right now, they four main manufacturers for their power supplies.

ATNG
ABS
Solytech
Deer

The ATNG units, which are the Extreme Series (EX-) and Performance Series (RP-), have been found by several trusted tech site to be very good actually. I agree that there are better power supplies to be had, but when tested these units received anywhere from 8 to 9 out of 10 on final scoring. Yes, efficiency, voltage regulation and ripple are not nearly as good as high-end power supplies found on the market (Antec, Corsiar, Silverstone, Seasonic....), but the regulation and ripple were found to be well within specs. The efficiency, while rated 80-plus, just missed the mark on one or two cross-load tests, coming in at 79 %... but otherwise it stayed at 80 - 81%.

The ABS units, which are the Libetas Series (LIB-) and Green Series (RG-), are good quality units that, like above, stay within specs on regulation, ripple, efficiency and rated power output. Although there are no reviews specifically tested under the Rosewill badge, some of the same ABS branded power supplies were tested and found to be pretty solid.

The Solytech units, which are the Stallion Series (RD-), did not fair as well under testing and found that , while coming close, could not put out their rated power output. This is due to Solytech listing their specs as rated at running under 25C temperatures.. which is a fairytale inside a PC. The regulation and ripple were also on the fine line of being out of spec, and on some units going out of spec by a bit.

The Deer units, which are the Value Series (RV-), are the worst of the bunch. Effeciency, regulation and ripple are a joke and this is where Rosewill takes a dramatic turn for the worse. This is the major "black eye" for Rosewill branded power supplies and I think that Rosewill/Newegg should just drop this line, and possibly the Stallion line, altogether.

I hope that shed a bit more light on Rosewill power supplies.. instead of the usual forum reply of " Rosewill PSU's suck... stay away...."

You first say Rosewill is not to be trusted.

You then say Rosewill is junk in the next sentence.

Finally, you conclude these as facts in your last sentence.

OK...

First... Well... you say that Rosewill power supplies are not to be trusted... but reviews of the ATNG units from a TRUSTED hardware tech site, one that is quoted numerously on this forum, has given them high marks.

JohnyGuru RP500-2 8.5 out of 10

The you have the Green Series by ABS:

Hardware Secrets RG630-s12 Golden Award

http://www.hardwaresecrets.com/article/881/10

Well... going by that, the Rosewill power supplies are not "junk" as you would have people believe.

In fact, the RV and RD series made by Deer and Solytech have been slowly taken off of Newegg's site and not replaced with anything new from those aging lines. The ATNG and ABS power supplies are in greater quantities now and represent the newer lines offered by Newegg/Rosewill Meanwhile, the older ATNG units that had Fuhjyyu caps in them are also being phased out , while the newer versions have better internal components. Also, all the newer models are all rated at 40C or 50C operating temps and most have 80-plus to 80 bronze specifications.

Those, my friend, are FACTS...

Now, I will grant you that when building, I would most likely not recommend a Rosewill unit when there is a better alternative in the same price range. But to arbitrarily say that Rosewill units are junk and cant be trusted is very misleading, when in fact they are anything but.

Your turn.....

The answer to your original question is somewhat historical in nature and somewhat psychological.

Rosewill started out in 2004. At the time they had a very bad reputation for offering low budget, low quality power supplies of questionable performance and value. It is very diffficult for veterans to forget the past.

Rosewill did try and improve their reputation by offering some better quality power supplies but they were still offering low quality power supplies at the same time. They're product line-up was inconsistent and still is to this day. This practice has a tendency to mislead consumers who are ill informed. If they read a favorable technical review they may incorrectly assume that the other psu's are of good quality when in fact they may be just average or below average.

Currently Rosewill offers 28 different power supplies. The company only submitted 18 of them to 80+ for testing and certification. Only 8 of those earned 80+ Bronze certifcation. One model earned a gold certifiction. The remaining 9 that were submitted were rated as ordinary standard power supplies.

It is the lack of consistent high quality that is irritating to veterans and a disservice to consumers.

Recently I bought a couple of Senteys (850 and 1kw). Holding up will so far.

And unlike the recent bust of RaidMax, Corsair and some others who were selling "Gold" 80+ certified supplies that when tested didn't even meet the "Bronze" level certification numbers.... these seem to meet what they are certified at.

Sorry guys, but I'm a BIG fan of Rosewill's 80+ certified line of PSUs. I've got the running, real world torture chamber that has proven them out over some better known names.
