the gutless, bloated, and fried power supply hall of shame

Re: the gutless, bloated, and fried power supply hall of shame

It's made by CWT, so it's probably a Neo Power , Smart Power, [type something here] Power

See http://www.realhardtechx.com/index_archivos/Page673.htm for Antec's models and oems

Re: the gutless, bloated, and fried power supply hall of shame

My guess is an SL350 or SL300 (one of the early StupidPowers)

Antec SmartPower without PFC

Re: the gutless, bloated, and fried power supply hall of shame

Ah, no review anywhere…

Re: the gutless, bloated, and fried power supply hall of shame

NOT BAD, after full recap and fan-mod

Re: the gutless, bloated, and fried power supply hall of shame

Sorry, didn't think anybody would care for a model number. Antec Smart Power SL400. The label is a royal pain to photograph- too many reflections

Re: the gutless, bloated, and fried power supply hall of shame

They probably blew the budget on the shiny label, instead of making a half decent power supply...

Re: the gutless, bloated, and fried power supply hall of shame

Hahaha so that's how they got away with selling those things at high prices

The sad thing is that they were decent power supplies with the exception of the caps and how the fan controler was set, a few cents in quality caps and a fan controler set to speed up at a lower tep and these could have been some of the most reliable PSUs of their generation but instead they were some of the least reliable.

Trash. I think when they made it they forgot to print the IT after SH Can't tell who made it but it kinda looks like my old POS Raidmax...Input caps are HEC, the rest are JEE. Surprised to see ANY parts at all for the transient filtering. The PWM controller is made by Fairchild (don't know the model) I threw it straight in the trash. Should I consider salvaging it? There are hardly any caps on the secondary....

High Quality Switching Power Supply

It's a Sun Pro.

It actually looks to use DC-DC conversion on the 3.3V rail, and the heat sinks look thick enough. Might be a keeper if you re-cap and fix up the input filtering.

EDIT: The Delta I posted before is alive. I replaced the caps, the smaller torroid coil, and the wires. It's fine now. It does the full 300W in spec.

^ How is the efficiency of that Delta at 300W and below?

[c_hegge]

Re: the gutless, bloated, and fried power supply hall of shame

I didn't do a progressive load test. It was late in the day, and I had other things to do, so I just took it straight up to 310W. The efficiency there was about 77% IIRC. Not great for 230V, but I've seen much worse.

Yeah the heatsinks look somewhat decent. What transformer it uses? I think it is the most basic element really. You can pretty much change everything else, but not so much the transformer (well, if you don't have bigger one with the same wiring from another PSU).

+1

And I was never brave enough to change the primary transistors of a psu.

Re: the gutless, bloated, and fried power supply hall of shame

The transformer looks like an ERL-33. It would be good for 250W after a re-cap, which is enough for a basic PC.

Re: the gutless, bloated, and fried power supply hall of shame

It's a Sun Pro.

Sun Pro it is, indeed.
I wouldn't touch that particular platform even with a 10 m stick. It's crappy at best. Decent source of parts, though.

Yes, you should. The caps may as well be garbage, but the secondary rectifiers on those are usually okay. The 5V rail in particular, may have 16 or 20A part. It's not a whole lot, but when you get a Deer or a Bestec that has space for a second rectifier on one of it's rails, this becomes a really nice upgrade. The MOSFET that regulates the 3.3V rail on these units is also useful. The 431 shunt regulator is also useful if you like to thinker/play with circuits.

Re: the gutless, bloated, and fried power supply hall of shame

I've never seen an ERL-33 transformer. What I have seen are EI-33 and ERL-35. (And larger sizes like ERL-39 in bigger PSUs, or EI-28 in the worst of the worst.)

I'll recheck tomorrow. I'm pretty sure it was a 30A part for the 5V though
