Re: AZZA Power Supply ?
I can't find any in-depth (where they actually open it and/or hook it up to a load tester/scope) reviews on the internet. The reviews on Newegg are mixed and I can CapXon primary caps through the fan grill in one of the pics. Since the primary caps are generally the best quality in the PSU and they used CapXon on the primary I can imagine what kind of garbage is on the secondary.
Not to mention I've yet to see a good $100 1KW PSU. Decent ones generally start around $170 and $200+ for the really good ones. -
Re: AZZA Power Supply ?
It may be an Ok psu.. the company distributing them distributes other good brands
read this from start to finish:
http://www.jonnyguru.com/forums/show...highlight=azza
question is do you really need 1000w?
what system are you planning to power?
later edit: one thing that's troubling is the MTBF of 100k @ 25c ... generally power supplies deliver this value at saner temperature ratings like 40c...
but the psu was tested by 80 plus in 2008, so it's not an old design or a very odd fake:
It will do what it says,as long as the system is well cooled if you demand a lot from it... and maybe it will be noisy....Last edited by mariushm; 02-01-2012, 05:05 PM.Comment

Re: AZZA Power Supply ?
Most AZZA's are superflowers. At this price range they will do their rated specs but ripple and voltage regulation will be approaching the max specs.

Re: AZZA Power Supply ?
Well i had some video problems' then computer showed i was having voltage spikes...Talked to asus and they said take out the 630watt ps i was using and install at least an 800 or up...I installed a borrowed 850 & have had no more issues with the spikes or video flickering i was having...Had a friend that also had to go from a 650 to a 800 having about the same issues...Comment

Re: AZZA Power Supply ?
The wattage has nothing to do with it.
The old power supply was supplying unstable voltages to the motherboard, probably. By changing the power supply, you just got lucky that the new power supply was giving better voltages, more stable ones.
Companies tend to recommend high wattage power supplies because there are still very cheap power supplies out there that are based on designs from the times of Pentium 4, which are no longer suitable for the modern systems.
Those power supplies advertise themselves as 400-600 watt power supplies but they're only capable of delivering 100-200 watts on 12v, which is nowadays used by the processor and the video cards - this is because around the times Pentium 4 existed and before it, the processor and the video cards were powered from 5v.
So by recommending 800w and higher power supplies, they just know you have about 90% chance of picking a power supply based on a modern design, that can deliver stable voltages.
But you don't need that much, you just have to be smart and pick a good power supply, from a well known manufacturer, with a 80+ efficiency rating. Your system may not even need more than 450 watts to run properly, but you can't just go and pick a 20-25$ psu.... good power supplies start from about 45-50$ in US, more outside US.
If you say where you live and what components you have in the system, we may be able to recommend power supplies and give you an estimate on how much that system uses.Comment

Re: AZZA Power Supply ?
Asus will tell you to replace EVERYTHING before the board - even if the board has a well known problem.
-
They did that A LOT with boards with known caps issues.
It's their standard practice.
-
Their goal is to wear you out with BS so you just give up in frustration and go buy a new board rather than carrying through with an RMA.

Re: AZZA Power Supply ?
We must be talking about a different ASUS! I have talked to plenty today that have had nothing but good service from them..Had fast turnAround & all..They just sent a friend out a new board where he wouldnt have to wait...Had his RMA fixed up while on the phone and he got the board the next day & he had the board back in the mail back to them...Comment

Re: AZZA Power Supply ?
That's because the Asus boards are in the rubbish can.
Not worth putting on the work-bench.
.
Most of the people that don't like Asus here are the people that do the work done in those repair shops.

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy... -
I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails
I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time... -
The sub developed a constant popping every couple seconds from woofer and power LED flickering with nothing but wall AC connected. Connecting an audio cable didn't change anything. It doesn't play but a second or two of audio in between the pops.
Opened it up and discovered the power supply is making a faint clicking or ticking sound.
I measured the amp's output to the woofer and it pulses up to 50mv DC to be driver. The pulses coincide with the power supply ticking/clicking.
I measured the power supply output going to the amp board and it too has this pulsing. Voltage cycles... -
Hello Everybody,
Trying to repair a power supply from a Russound CA4 Multizone Controller (picture attached)
Russound no longer supports it but were kind enough to provide a schematic of the power supply (pdf attached).
The outputs marked 12v and 20v are all measuring only 1v.
The board is clicking, which I think means it is in something called hiccup mode when the flyback transformers switches because of an internal problem or something else on the board Overloading it.
The capacitors physically look clean (no bludgesor leaks) and...
