The worst PSU manufacturer?
What is, in your opinion, the worst Power supply manufacturer out there?
Trust me, I know, I just wanted to see how bad they were since they were only $10 each. It was worth it to see them smoke and spark
Cheap thermaltakes are great, got a couple for builds and they cost $30, work perfectly. Personally I never spend less than $70 on PS's for my computers. I have silverstone 600's in my game rig and my primary media center pc. Enermax in most everything else at home.
I've also had a couple topower's shoot flames, they'd be my second worst in the list.
I've probably replaced more no name PS's in my various jobs and personal business than all other components combined.
Some day people may learn that cheap is never good with computers. Amptron's anyone? :twisted:
I have to disagre with that list. I've had many Deer, Cooler Master, Atehna Power (in servers), Rosewill, and Allied (in servers), that have performed very well.
The list also makes it sound like you need the most expensive ps's for anything more than an office machine.
I've built many light duty gaming rigs with 300-400 watt PS's that have lasted years, even current systems will run fine with low wattage Rosewill's for example. That list needs to specify quality by model, not manufacturer and/or product line.
PowMax - god.... ther power supplies cant even deliver a tenth of their rated capacities.... theyd do a lot better spending money on r n d teams, rather than hiring graphic artists with no technical qualifications to bling up their products
(the brand i saw at a pc market) - lol absolute bullsh1t
it had no brand name, and 10 bux aud cud get u:
800W ATX 2 compliant
20A3.3 and all rails at 1%
the psu dimensions itself wer abt 5x5x 10
I know this is adrresed to mpilch, but:
What is everyone's opinion of AOPEN power supplies? I have a 250W thats still gattling on after 4 years run 24/7
on a P4 1.6, 2 sticks ram, 1 hdd, fx5500, 2x optical, 3 fans, mobo, 2 pci cards 1 floppy
Its never shut down or overheated considering i used to run seti at home 24/4 for 4 years
Apevia used to be called Aspire. I've owned two of them in the past and they did the job well enough. I've since seen them listed as backballed by virtually all lists of power supplies, so either I was very lucky with them or I never drew on their full power potential, which might have been non-existent.
roswell is the bottom of the barrel
<--- see those red fans on top of $6k in parts (my avatar) they are Roswell - omg! they were they only red fans could find.
i got my kid a rosewell 19" monitor it kicks azz - but i did have to mod it to get the dvi plug to fit - they told me they send one - never did!
aspire fans rock! psu's?
ultra sux's i did return the psu to tiger - the connectors were so long did not fit the cases on the first
I GOT ONE -- I REMEMBER!!!\
A REALLY BAD PSU!! these psu's suck azz i had problems 2-3 year ago with these COOLMAX
this was in 2004 -05 these psu's have very slow moving 12cm fans and run very hot.
i shipped systems out west in AZ and CA and they would shut down after 30-60mins. I was using 550 watt coolmax with 6800 ultra and 6800 GT's.
COOL MAX SUCKS -they cost me quite a bit of money!
AOPEN's been making them for a while, but not for retail. Mainly oem for their cases and other buyers. They seem to be alirte from my experience, but i wanted comments from others. As i said, my system actaully drew about 270W (its rated at 250) and i ran it 24/7 straight for 4 years. With only about 1 full power off every 6 months.
Viewscope. They wen tout of bisunees quite a while back, for obvious reasosn
You can't go to say newegg or whatever stores you guys have in the states, but you can still find em floating around. ie
-maybe smaller niche pc stores
-ebay auction places
NEVER BUY THEM!!!
not only are they about 30% overrated, but they run very hot and the voltage rails are out of spec. Normally, ther within 5%, but ejecting the cd tray is enough to cause the rails to fluctuate by abt 0.6V.
strnage thing is though, therer psus have the best protection circutry iv seen. I had one in an old system:
Pentium 1 200mhz, 32mb ram, 3 hdds, sound card, network card, dvdromd rive. on a 120W psu.
the system wud boot, but wud overload and shiutdown. then 10 minutes later, iut would power up, then cut, then power up.
i only discovered that after about 16 hrs later, when the thing had gon throuhgt like 65 overload/reset cycles.
Quote:1 full power off is about 2 too many. You ricks major damage to your system like that.
I'm not sure what tyou think i meant but i reckon you got me wrong
Full power off - shutting down the pc and unplugging just for maintenance
hehe, i traded in an crapass 430Wer psu for a nice TT 750W toughpowe for $120. PC store guy mustnt have had much experience with that brand. That brand (name of whihc i cant memba) did abt 210W in tests before shutting down from thermal. Didnt't help that they used cruddy low grad 8cm fans.
I gave up on trying to save money on PSUs and I just buy PC P&C. The things never fail and work exactly as advertised. Worth the extra $40 or $50 in my book. I have a 510 that i really beat the hell out of and the thing never sags at all. Watercooling, 67% overclock on the CPU, two 6800GTs in SLI overclocked, 3 hard drives (2 in RAID 0) etc. and the 510 just motors along. Might drop .01v when stressed but that's it. I'm planning a dual loop watercooling setup so I relented and bought a used PC P&C 750 Silencer.
Stick with the stuff that works and you won't be sorry. A couple of hundred bucks for the one thing that touches everything in your case is a good investment when you have several thousand dollars riding on it. Plus solid voltage is a necessity for a really high end O/C.
No flames please. I know I am a fanboy so don't bother hammering me. It won't work.
In answer to the question, I have to say the PSU company I hate the most is Antec. I admin on an Asus site and Antecs have been the cause of more hardware problems than anything I have ever seen. The older units are fine but the units from the last two years are a nightmare. Why they are the worst is that they have/had a trusted name and charge a moderate amount of money for one of their PSU's. Builders trust them and then have all kinds of problems until finally their system stops booting. Antecs fail like nothing I have ever seen for what is supposed to be a quality product.
Spend $35 on a 600 watt PSU and you deserve what you get. Spend $100 on a 600 watt unit and should at least expect that it runs well for a time. Maybe it sags and heats up but Antecs cause all kinds of problems and then die catastrophically, in some cases, taking other gear with them. I'm surprised the very comprehensive list here hasn't registered that. I'd be more than willing to document it at the Asus site if it would help spread the word
(dw, im not gonna flame you)
Just out of curiosity, would you know what the problem with Antec's were? Poor voltage rails, crap tolerance, ripple, overrating etc?
When i bought a new pc, i considered Antecs, but got very put off after reading all the crap about their exploding capacitor fiasco.
exploding capacitors was an issue with two models as far as I know. The other problems are garbage parts and terrible quality control. HF has some more info on it and has a list of the do and do not buy Antecs but I think he problem is a lot worse than even they know. Plus, If I have to pick and choose by build date and model number i'd rather avoid the problem altogether.
What we are seeing is the rails seem stable but have very hard drops. Of course the system gets all screwy. After a couple of weeks of that behavior the PSU dies completely or dies half way. In other words the the mobo LED stays lighted but the PC won't boot at all or and this one is worse, will boot intermittently.
The intermittent boot is the worst and we have had at least 6 people lose other high end components when the thing finally died. We're only a small site (4k members or so) that deals with Asus mobos so it is fairly easy to see a trend occurring there.

[H]ardForum at http://www.hardforum.com/ They have a pretty extensive PSU section there.
My COOLER MASTER Real Power RS-450-ACLY ATX12V 450W Power Supply seems to work just fine for the last 6 months or so since I built it.
Of course, I'm not a gamer, just an "ordinary" business (online stock and currency trading, mostly lots of 2D charts, etc.) user and net surfer.
I read the reviews at newegg and chose this PS for it's good reviews and mid level price. I didn't know much about PS's so I think this is a good compromise. The PS cost more than the case.
My whole computer runs very cool with stock heatsink cooler and fans. Maybe I'm not stressing it enough.
I'm running this:
Asus A8N 5X
AMD X2 3800
2 gig Corsair XMS2048 3200
PNY Quadro NVS 440 PCIEX 16 (Can run 4 monitors from 1 slot)
WD Caviar SE16 2500KS
Samsung 16X DVD+R DVD
Sony IDE DVD-ROM
Samsung 1.44 3.5 floppy
Cooler Master RS 450 in a Cooler Master Centurion 5CAC-T05
Logitech X-230 32 Watts RMS 2.1 Speakers-OEM
2 AGM CW 19" wide screen monitors
MS XP Pro - NOD 32
6year old eh
the ones they use now r crud oem cheapos
shows how much cost cuttings been goin on
thats what i have heard about the newer ones.
i have 2 older dells that i have added extra,s to.
the only problem i have everhad was adding a cheap after market
ram stick that really messed things up after a month of use.
I looked in my junk drawers and found a couple of "400 watt" power supplies. They cost the equivalent of less than $15 each in Saudi Arabia. One is a Rexpower with a 20 amp 12 volt rail. The other is an iBest with an 11 amp 12 volt rail (obviously unsuited for anything using a modern, power hungry video card).
The IBest seems to be built a little better.
These cheap PS's are surprisingly reliable if they do not fail immediately and you treat them like a 250 w ps and do not load them too heavily. The sleeve bearing fans are the weakest point.
Good power supplies are very hard to find here. Saudis want to do everything they can as cheaply as possible.
They have gotten cheaper, but no where near as cheap as the powmax level of cheap! I've got some old PIII 866-1G Dell's for simple servers, they have been running for 5-7 years I'd say, 24/7/365, without a single glitch. Course they have to be on quality UPS's to insure clean power. I have 7 UPS's for my servers and media servers, my wife's PS died once, but that's cause my son keeps kicking her computer!

on my girlfriends dell i added a aftermarket gpu as it had onboard
and cut a hole in the side and added a t.t. 120mm fan.
one day my 3 year old neice was on the computer and stuck her toe
in the fan.
i thought it was funny but she didnt.
Has anyone heard of a PSU brand called Unicase?
I've got one in my system at the moment, are they any good? Or should I be thinking of getting a more reputable PSU(Antec, Thermaltake, etc).
P.S. I live in Australia, these PSU's might only be used here and in Europe, at least thats what my local techie told me!? "Go look it up on the web" he told me. :?
never even heard of it yet alone seen it in aus... the ONLY place you might find it is at the muirfeild high computer market. (formerely north rocks westfield pc market)
(if ur in other parts of oz, north rocks is in nsw, sydney)
some guy tried to sell me a bulk pack of 300W psus x 5 $50 buck for the lot
he sed it was so cheap cuz it was oem...
Quote:Wow, just looked googled powmax to get an idea of what kind of crap you guys where talking about. They look like cheap ripoff versions of already cheap ripoffs of psu's that where designed by retarded sea urchins. In China, in a tunnel, under a fireworks factory.
Damn. Tell us what you really think.
