SFE-9FD

It's surprisingly good for $6. The input wires, transformer, and soldering quality look horrible, but I wasn't expecting it to have so much input and output filtering and a switching IC. It even has real X and Y class caps.

Input: inductor, X cap, 4 1N4007 diodes, and a 6.8µF 400V "RC" brand cap
Output: SR260 rectifier diode, 470µF 16V cap on pi filter input, 220µF 16V cap on pi filter output

All caps except the big 400V one are LSHC brand CL series.

I'd say that it could be improved, but it isn't as bad as some of the cheap power supplies I've seen. It isn't very well regulated, but it's probably good enough for most things that need 9V input.

[Pentium4]

Yeah it looks pretty good. For a 6W adapter, I'm also surprised to see a switching IC. Nice! I'd just redo some of those solder joints and call it a day. What's the fuse rating?

[lti]

I didn't look at the fuse rating, and I didn't see how bad the soldering was until I had already put it back together and looked at the pictures again.

This is a new power supply, but the TOP222 has been discontinued. I wonder how old it really is. At least the IC is old stock (or fake, but it works well enough that I think it is a real Power Integrations chip).

[Behemot]

Well for 6 watts at high voltage, do you think a fake would do worse? ;-)

[ReeceyBurger123]

Well this is my first post in this awesome thread, I have many atx power supply's that I will take pictures of and share them to see what you guys think.

Here is the first psu that I have recently recapped as it was full of fuhjyyus, its a hiper hpu 4s525 rated to output 525w max its manufactured by andyson and seems good enough for 450w. It has 3 powerlogic sleeve bearing fans that are controlled by a fan controller on the back where the ICE connector is.
Specifications listed:
Active pfc forward design with a pfc booster that takes the rectified dc and boosts to 385-395 vdc then its divided and forwarded.
I couldn't see what the primary transistors are.
5vsb is controlled by an Ic.
Transformers are decently sized (height and width)
Output capacitors were all replaced from fuhjyyus to jamicon for the smaller caps and for the larger samxon, ucc and Panasonic.
5v 1* 4700uf 10v ucc ky 1* 3300uf 10v samxon rs
3.3v 1* 4700uf 10v ucc ky 1* 3300uf 10v samxon rs
12v 2* 3300uf 16v samxon rs
-12v 1* 1000uf 16v Panasonic Fr
-5v 1* 1000uf 16v Panasonic Fr
5vstb 1* 1000uf 16v Panasonic Fr
Fan controller 1* 2200uf 16v ucc kze
Primary capacitors 2* 820uf 200v
Output rectifiers are all double banks of sbl3040pt on all rails.
Please could you let me know what you think about this psu is it decent it hasn't ever been used so its all brand new?
I replace fuhjyyus on site.

[ReeceyBurger123]

Here is a zalman 460aps psu that is rated for 460w its manufactured by spi seems good but came full of blown capxon capacitors that caused a massive amount of voltage ripple, they were all replaced with good brands and the voltages returned to normal.
Specifications listed:
Double ball bearing nmb fan controlled by thermistor mounted on the underside of the secondary heatsink.
Gbu805 bridge rectifier.
Active pfc.
Pair of 10n50 transistors.
Transformers aren't that big but ok.
Output rectifiers are all double banks I could read there ratings as its so densely packed.
This psu has low uf output capacitors but ripple is ok:
12v 2*1000uf 16v Panasonic Fr
3.3v 2*1000uf 16v Panasonic Fr
5v 1*1000uf 16v Panasonic Fr 1* 2200uf ucc kze
Primary 330uf 450v Panasonic
Smaller capacitors Jamicon
Let me know what you think about this psu.

[goodpsusearch]

It's an FSP! Not bad!

[Pentium4]

Nice job recapping those units, they both look good Love the Power Logic fans in the Andyson unit. Main transformer on that FSP is plenty big. Should be insanely reliable now, especially with that fan!

[c_hegge]

Yah. With a decent 2BB fan like an NMB and entirely Jap Caps, the PSU should never fail

[Pentium4]

A buddy of mine said this Delta was going to be taken to the dump, and he snagged it saying "I know a guy who would love this thing!" So I decided to recap it, and believe it or not, remove most of the glue.

Never seen this model before from Delta. It got about 5 years of use. All the caps were in the spec, however the Taicon after the coil on the 5VSB was barely in spec, and so were the Ltec LTG on the 12V rails. Each 12V rail uses a 20A schottky.

I hope your friend told the guy in no uncertain terms that Deltas must never be tossed out, especially if they are still working!

That looks like a really nice PSU, though. Definitely worth saving.

[ReeceyBurger123]

Awesome thank you for your replies, I will post more pictures some time today

Awesome psu why was he going to throw it out, massive components, rubycon primary and ultra precise output ratings 390w exactly great grab

Well it's Delta, they probably have a ton of designs...

Anyway:
The design reminds me kinda of the GPS-400AA series I once had...

[Behemot]

Yeah it is similar to GPS-x00AA/AB, main differece is this one is upgraded to active PFC and has two driving/protection ICs

Hey, that looks like an NP160(?) I recapped a few years ago. That one didn't have APFC, but was similar. The heavy, staked secondary heatsink gave it away!


I do remember the glue being easier to remove than in the Bestecs.

my GPS-400AA also had aPFC...

[Behemot]

The AB I got is passive with voltage doubler and switch selector.

This psu I brought off a boot sale for 99p, its a fsp250 60hen oem is spi this psu wouldn't power on when I first tried it this was due to two bloated capxon capacitors replaced with samxon Gf just to test the psu and make sure that it works before I install good caps, I replaced the main iec connector as the original had rusted and corroded, seems good for 250w maybe more ?
