Anyone have any opinions on Dynapower? They have a PSU that looks very similar to the Sparkle 300w supply, but at a lower price - http://www.newegg.com/Product/Produc...82E16817255007

Ludicrous gibs!

I've had great luck with Sparkle PSU's..... If its the same innards, I'd say go for it.... Never heard of 'Dynapower'....<--- Badcaps.net Founder

Re: Any "yay" or "nay" on Dynapower?
I really can't read the UL but it doesn't seem to match what's here http://www.jonnyguru.com/SMPS_UL.htm My gut says thumbs down.
eWiz.com has several 360W Enhance units for < $25. Zap posted pics in the PSU photo thread of the one he has. They should be loaded with Teapo caps and that would probably be better than what Dynapower offers.
Some favor the 5V rail, others the 12V, so choose well.
If you want a real bargain on a SilverStone 400W Element, madmat over at jonnyguru.com has a near new one for $40 shipped. It won't last.

If it is the same crap as Dynex, I'd give it a miss. Dynex is made by Shenzen-Chi Yuan Industrial Co., Ltd.Q6700 @ 3.6 GHz

My Sparkle (SPI) PC power supply has broken. Originally, there was totally no power output. The 5V-standby was not there. I have replaced a few bulged capacitors but not helping.
I was trying to do more troubleshooting but burned more components. Some got burned so badly that the markings were gone. And also, the markings of a few transistors were gone because the component surface was worn out somehow.
If you happened to have disassembled the same PSU model, please help to provide the markings of some of these components.

Hi Guys,
I need to replace the dual rail power supply in this unit (board damaged irreparably - by me!).
I have the schematic (attached) - but it does not (unhelpfully) show the value of the Pos and Neg rails.
Someone has suggested possibly + and - 42V, but as the smoothing caps are only rated at 50V this could be a bit close to the mark.
I am hoping Alxxxxpress might be able to come to the rescue and I am thinking somewhere in the 32V 8A region? Any suggestions/observations would be welcomed.
Many thanks.

Hi,
Recently I gave a shot at recapping this Excellent power IT ATX 300 lc clone doohickey PSU. After I replaced all bulging caps and the 47uF 50v in 5vsb I turned it on. 5vsb and ps_on are spot on. So I shorted the ps_on and it dies after a split second. 5vsb still is generating, all other lines also generate voltage for a while but they all discharge so fast.
Now I am sure this isn't a problem with the 5vsb damaging the PWM IC or BJT circuit, but I have no idea where to go next. Maybe replacing all the smaller caps? -
I have bought computer switching power supplies from Electronic Goldmine before and every one of them the capacitors were bloated and or leaking out of the capacitors so I am sure that these are going to be the same way five or six years ago I had bought some 300 and 350 watt computer switching power supply from Electronic Goldmine these are all from FSP brand
Here is the listing for this switching power supply they only had three of them in stock and I bought all three of them

Has anybody tested this product? Posting this question on a Facebook tech group I'm in got a few responses like "that kind of thing corrodes the tips" and "just using normal solder paste is much better" so I'm not looking for generic responses like that, but rather, does anybody know for certain whether this exact product is good or bad for soldering iron tips?
