Because in that era they started using a lot more 5V current. As
always, a lower wattage PSU isn't only limited by # of watts but
current available per rail. A low current PSU can marginally work but
then it fails sooner (take eMachines for example).

PC Power & Cooling and Delta both make high quality 250W units. The
vast majority of other manufacturers don't come anywhere near the
quality till higher wattages, excepting some OEM-specific PSU one
wouldn't find at retail as was the goal in making a purchase. Maybe
for servers, but that's not the form-factor needed.

A) Why are you answering a question I asked of (e-mail address removed)?
Are you one and the same?

B) Your answer is not to the point of why (e-mail address removed) said
*NOT* to use PCP&C or Delta.

C) PCP&C no longer makes a 250W ATX supply, only a 230W SFX supply.

yes, that was a throwaway address I used for remote posting.

No, I wrote what I meant poorly then you misinterpreted it. I wrote
"better than a came-with-case 250W from any brand except maybe PC Power
& Cooling or Delta."

In other words, better than 250W, unless it's (except) PC Power &
Cooling or Delta.

Well this was a few years ago, I'd imagine that particular FSP 250W
unit isn't made anymore either, now replaced by whatever their more
recent 250W version is.

No. I asked a poster why he made a particular comment. Unless someone
else knows why another made a comment, I'd say the question was
directed at that one person, no? Follow the thread.
Meanwhile refrain from stupid and rude comments.

Virtually, but really?

The heatsinks and transformers in the ones I checked were identical
(and the 300W models had the same transformers as the 350Ws). I believe
the output diodes were the same, but some, either Sparkle or Fortron
brand, had unmarked high voltage transistors. All the 300W ones passed
my 10-minute 380W test, with about the same percentage of voltage sag
(not much)..
Comparing yesteryears 250W came-with-case to today's retail models I'm
also considering the two most common failure points, the caps and fan.
There are still some FSP PSU that unfortunately use the crap Yate Loon
sleeve bearing fans (like their 12cm fan models) but quite a few now
have the vastly superior NMB fans.

Do you know if Muhua fans are OK? I'm not implying that FSP uses
them, but I'm wondering because the 120mm fan in my first 350W
Wintech-made Ultra V-Series failed to start in 2 out of 20 tries, even
though all the output voltages measured within specs. The replacement
PSU's fan started every time (I probably tested at least 90 tries), but
it's probably from a different production run (no Muhua model number or
UL registration on it). I may add a small capacitor across the
thermistor to give the fan a voltage boost at start-up.
