The 2012 El-cheapo PSU Roundup

It looks good. As long as you don't expect its rating from it, it will probably work well for a low end PC.

I will just treat it as a 250 watter

I think I figured out who the OEM is. I Think it's ePower/Topower/Zumax. I have an ePower with the exact same layout and parts except it has ZU- markings on the transformer, ePower on the label, Topower UL number

[c_hegge]

Possibly, but Topower usually have "TOP" markings, although I haven't seen a Topower PSU for a while now, so things could have changed. Many of those cheaper Zumax PSUs are actually built by Leadman, although I don't think they are behind these PSUs.

Yeah I know but I think Topower has been mixing it up...Oh I know I have seen some of the Leadman ones, they're pretty appalling. I hate Leadman as much as you hate Teapo....haha

In the summary table for the Besta PT-550, you mixed up the 5V and 3.3V ripple values.

Also, it's clear from the photos that those Chemi-con primary caps are fakes. (It would surprise me if they were the real thing, given the general lack of quality in those PSUs...)

I had a feeling that they may have been faked. I just didn't desolder them and verify. The primaries rarely fail anyway.

I have also fixed that mistake with the actual specs table.

[LongRunner]

What about this???

...I was able to bull a fair bit more than this...

[c_hegge]

Fixed

Re reading these reviews I was a little surprised by the A1, how did that thing manage to pump out 320W with only 330uF input caps (that may even be 220uF) ?
