Re: Power supply build quality pictorial

Look at those discrete diodes on the secondary heatsink.

Why do manufacurers do that is it cheaper to use discretes then to use the proper TO-220 package?

Not to mention discretes in that package aren't designed to transfer their heat to a heatsink.

Re: Power supply build quality pictorial

Look at its Y capacitors: completely absent. So the Emi filter.
Small caps, tiny wires, no protections, small transformers, only one coil: a Deer is a better products, this one competes only with Powmax

Re: Thermaltake Toughpower 430W

Thermaltake 430W XP550NP. Group-regulated, No APFC, basically a cheapie unit with highly questionable caps.

Primary side: 2 x 680uF 200V CapXcon
Secondary side: Ltec, Suscon and Teapo.

Will be recapped with:
NCC KMD 820uF, 200V on the Primary
UCC KY, LXZ, KMG and Panasonic FM on the Secondary.

PCB says 300W @ 250V, so not only is it of questionable build quality but it is actually "overclocked" on some pretty shady components.

Um.... yeah I kinda have a unit identical to that one powering my main computer.
That unit cost me nearly $100AUD when I got it about a year and a bit ago.

seems the labor to prepare those diodes would ofset any savngs over a proper to-220 device.
well maybe not if your products are assembled by child slaves.

Sparkle "Power-Q" ATX-300GU (built by FSP)
Date code on PCB is 0445.

After about a year, I got a phone call from my sister that her motherboard heat alarm was going off. About a day later I came down and noticed the PSU was baking, and the fan was dead. I was impressed it lasted like that.
There's a little circuit board attached to a heatsink for the temperature sensitive fan. When I replaced the fan I gave up on trying to hook it up "properly" to that gizmo.

I recently recapped this PSU. Mine had Teapos and Jamicons in it, almost all are general purpose 105C. None failed even with that overheating incident. One of the photos shows the strange rubber ring I found underneath the 3300uF Teapo. It's not the bung - the cap was still intact.
There's 1 16V cap in there, and it's a difficult size, 2200uF 10mm IIRC. Lesser voltage caps are also still 10mm, so they're easier to replace.
Input caps are 2x 470uF 200V Teapo LXK, as can barely be seen in the overhead photo.

Re: Power supply build quality pictorial

Fortron/Source FSP300-60PFN(12V)
Date code on PCB is 0151

This is apparently one of those newfangled jobs with 1 input cap. It's only 220uF - is that normal?
I just got 4 of these, but only this one has been opened yet. This PSU has many Fuhjjyus in it, especially on the input side. Output has 1 Fuhhjjwhatever, 1 OST, and a few Teapos.

They hot glued a vertical PCB at each end. Looks kind of ghetto, but I guess it works.

ratings:
3.3V 28A
5V 30A
12V 15A
5Vsb 2A
-5V 0.3A
-12V 0.8A

3.3+5V 180W

Re: Power supply build quality pictorial

ugh... I forgot to post the ratings on that Sparkle, and it's too late to edit.

Sparkle "Power-Q" ATX-300GU:
+3.3V 20A
+5V 30A
+12V@13A
+5VSB@2A
-5V@0.3A
-12V@0.8A

3.3+5V=175W

Re: Power supply build quality pictorial

Re-posted here, in the newer thread.
I've done 2 of these 4 fan Super Flower 550W monsters this week and am using one now. One took 4 caps, the other took 6. When the fans are on full it is noisy as hell but on auto or slow and the 2 little top fans removed it's not bad at all. On the website it's the 4-fan type at the bottom of the page.

Super Flower!
And they have a "Golden Heat-sink"

Re: Power supply build quality pictorial

Ipex/Seventeam ST-251R
Rubycon USR 470uF 250V primaries; the rest JP CE-TUR.
2200uF (bulging) on the 12V rail.
2200uF 10V before and after the output inductors of the +5V and +3.3V rails (the capacitor after the +3.3V inductor was bulging).
The capacitor before the +5VSB regulator was bulging too.
D83-004 rectifiers for all rails (two in parallel for +3.3V)

Re: Power supply build quality pictorial

Here's the PSU that I had in my newest PC until it died (see the Whistling PSU thread). This PC sure seems to be going through a lot of PSUs!

X-Power ATX-400D 400W Dual-fan

This PSU is packed with Teapos everywhere, both on the input and output. For those who say Teapos fail without physical signs, these sure didn't! Three of the Teapos on the output side have bulged, with one actually exuding a small amount of electrolyte. I've also included a close-up picture of the Teapo that's leaking.

Re: Power supply build quality pictorial

Decided to clean the PS3. Very dusty but the powersupply was clean. Sorry for the blurry photos. I swear it looked good on the tiny screen on the camera.

Re: Power supply build quality pictorial

Allied AL-A400ATX Max 400w




Four failed "DON" brand caps, yet all the other g-luxon's were fine.


Top-down view.

I will not be attempting a recap on this one as two of the caps are hidden under the heatsink. Already in the trash bin, before anyone gets any ideas of saving it

Re: Power supply build quality pictorial

Enlight HPC-235-101

This one has a date of '99 on it... it was in a Slot A Athlon system built in '00, so I'd believe it. Still works great, even with the original g-luxon caps!




Those are Ruby's on the input side!


And the unfortunate, yet not failed, G-Luxons.

Re: Power supply build quality pictorial

Dell NPS-200PB-73M
This was pulled from an older Optiplex GX110 unit. First glance, a very solid unit. Made by Newton Power, has Rubys on the input side, and a mix of Ruby's and UCC on the output. A very solid 200watt ATX supply, with one major flaw. Dell, in their infinite wisdom, saw fit to wire this not as an ATX supply. Still has an ATX plug on it, but if you plug it into a standard spec mobo, the thing screeches and wails like no tomorrow, before you even turn it on.

Disappointing, because I was looking forward to using it as a spare...

Allied 350W: am I blind?

After reading this thread and watching all photos I decided to open the Allied 350W I bought some months ago as spare PSU for testing purpose.

I have lost the warranty because I have broken the label... but I couldn't resist .

The big surprise for me is that on the box they write PFC-MATCHING THE SPECIFICATION OF THE POWER FACTOR CORRECT OF EUROPEAN UNION 2001

Somebody can show me where is the PFC? I can't see it .

I suppose the Asia X output caps aren't good, am I right?

I have another question: what is the brand of the caps in picture allied3?

To end the post: the only good thing I see in this PSU are the 2 fan .

I have spent 26,00€.

Ciao

Re: Power supply build quality pictorial

well. i guess in 2001 thetre was no law for pfc so they didn't put any in...hehe...
this psu has no pfc. active of passive.
yes, asia x is crap(somebody mentioned it on this forum, do search), and this reminds me of this
https://www.badcaps.net/forum/showthread.php?t=5727

for 26€ i get fortron ( https://www.badcaps.net/forum/showth...hlight=fortron ) that looks like tank comapred to this "gutless wonder" as kc likes to call them...

your only excuse for buying this can be that you were not reading this forum at the time
<wink>

Re: Power supply build quality pictorial

no pfc there.
not even a cheap choke.

Welcome to psu hell

Somebody can show me where is the PFC? I can't see it .

In factory: the guy at the assembling line forgot to include it.

I suppose the Asia X output caps aren't good, am I right?

Absolutely right: Asia X is a new name for Fuhjyyu, which is the crappiest badcaps brand known to present day. Good only for shooting.

I have another question: what is the brand of the caps in picture allied3?

It's usually called Saturn logo, but the real name should be YC (even guys from capacitor.web aren't sure about it). Better than Fuhjyyu, worser than all others. My old Allied DR-B400BTX was full of these craps.



You have an I already saw it feeling, right? Me too: it's a clone of yours.

To end the post: the only good thing I see in this PSU are the 2 fan .

Cheap sleeve bearing ones: they become noisier over time until they fail. Don't put them into your friend's P4 unless you want to replace them in a year or so.
