I want to upgrade to a 400W power supply, so I did my research and found that Fortron, Antec, and Seasonic are the top brands (with a reasonable price tag). Since Fortron is the cheapest of those, I'd like to get the AX450. But after doing more research, it seems that all of those brands have suffered from bad caps, and even some of their current models are suffering from bad caps. I haven't seen anyone mention whether the AX450 has bad caps or not, but I've already seen people mention that 2 other Fortron models have bad caps. I'd rather not spend more than $60 on a PSU... is it possible to get a good PSU without bad caps at that price? Or are you taking a huge gamble no matter what?

Re: Are there any good PSUs without bad caps?
Another approach is to buy a cheaper power supply. I recently bought a 500W with 120mm fan (silent running) and power factor correction for A$45.00. I then replaced all the output caps with Rubycons. This will ensure no bad low ESR caps. This supply is quoted in my signature.Gigabyte EP45-DS3L Ultra Reliable (Power saver)

you might get lucky with a late model Seasonic S12 430w. 3 year warranty as well.
mileage seems to vary on PSUs. i guess it is down to bad quality control at the cap manufacturers. some run for years with fuhjyuu, teapo etc, others not. cooling may be a factor also. or perhaps even psu design. the most important thing is to have a quality design so that when the caps fail something nasty doesnt happen to the pc.Comment

I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.
For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

This one should make @Pentium4 smile
(if he is still reading BCN forums) – I got a new old stock / open box Casing Power MPT-301 PSU on eBay for $4 total. 
Yes, it’s a very generic-looking box, but the manufacturer isn’t (at least not back in the days), which is…
Macron Power Technology Co. LTD.
Let’s look at the PSU itself.
The shell/case also appears quite generic, like many “sold-with-the-PC-case” units. However, the shell is well-formed and has decent steel thickness. In terms of... -
Hello,
First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.
I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.
I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."

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...

nichiconare what i used because i had heard the voltage doesn't matter as long as it is more than the original cap. i'm now reading that high voltage may make the cap's esr too high. is this a good cap for replacing those oem ones?1500 µF 16 V Aluminum - Polymer Capacitors Radial, Can 8mOhm 2000 Hrs @ 105°C
