Is it just a rebrand? I think they've been making their own supplies back than and Delta bought them later?Less jewellery, more gold into electrotech industry!

Re: Enlight GPS-350CN-101
Now there's some warm Spring weather, I revisited this
Having bought some new A1013 transistors, I couldn't see much difference in testing them, versus original B647
So I tried a new A1013 at Q301 - and the 350CN still wouldn't start
Remembering once when I forgot to connect the old HDD I'm using as a load, and 350CN's fan started spinning, I tried using a different HDD
And the 350CN started
All voltages looked OK at both ATX and Molex connectors, so I put it into a computer and it worked perfectly
I decided to replace original B647 into the other two 350CN I picked up, and they were fine as well
Moral of the story - make sure you're working with known good devices

Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though.
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

For today's thread, I have a KingWin ABT-650MM ATX PSU. Official web page with the PSU specs is still up and can be found here:
http://www.rmac.kingwin.com/products.../abt_650MM.asp
I just can't help it when I see a broken / for parts PSU on eBay that's listed for cheap and looks at least somewhat interesting. Well, OK, I won't lie – on the outside, this PSU looks anything but interesting. It's a plain gray box with colorful “spaghetti cables”.
What mostly drew me into buying it is its 2x PCI-E power connectors... -
Recapping the power supply board for a Samsung 305T monitor, everything is Capxon except 2 Rubycons. I can't find data sheets matching these online, so don't know what ripple numbers, impedence, etc, to look for. There are a few different looking GL series data sheet PDFs, but the listing that matches the capacitance and voltage is a much bigger case size. I've narrowed down selections with lead spacing and case diameter, and what's in stock at Digi-key
1 x Capxon 1000uf35v GL C720(is this a part number or batch number, can't find it anywhere) 105c

So a couple of days ago I picked up a 2009 8-core Mac Pro in "as seen" condition at a price that was too good to pass up, got it home, eventually managed to install OS X on it, and then it died while downloading updates. This machine looks like it was used for heavy video editing work as it still had a Blackmagic capture card and two GPU's installed, but I expect we'll see a lot more of these 2009 Mac Pro PSU's failing soon.
After it died, the machine made some clicking noises, like it was trying to fire a relay but something wasn't working right, so it kept randomly clicking...
