I bought a computer at the right price the other day because it

the wall. Give it 30 seconds or so and it would do the same thing
over and over again for as long as you had the patience to do it.
The PSU is a Usicase 400 watt Silent Power Model 33OU-SCE.
I replaced this PSU with another PSU and the computer works well
so it would seem that it is not the computer causing this
switching off thing. The computer is an Athlon64 powered ASUS A8V
board. Any ideas anybody?
Power supplies are rated here. I don't see the brand in question,
but perhaps it is yet another entry for the "Tier 5" group.

I don't think the rating is that good. I had a Fortron "high quality"
fail after a year, due to bad components. I also have had a look
into a "high quality" Antec one. They are showy, but belong
squarely into Tier 4. I have had 3 (of 3, one a Dark Power Pro) Be
Quiet fail on me with moderate load. Definitely Tier 5.
From examining several different Enermaxes, I would say all fall into
Tier 2. However I am pretty sure there are no widely available PC
PSUs in Tier 1 or Tier T. The author is kidding himself. Some (not
all) industrial PSUs can make it into Tier 1, at roughly 5-10 times
the price of a Tier 2 PSU.
I think the PC Power and Cooling power supplies belong in Tier 1, if
only on their reliability. I have one of their power supplies that
has been running 24x7 for around ten years. It cost more up front
but was worth it.
I also think that the author is kidding himelf.
He puts AcBel PSUs in Tier 3. Ok, they might not be all flashy but they're
extremely well made. (They weigh a lot more than other, higher rated [in
that chart] PSUs weigh. Weight is a good indicator of quailty IME with PSUs)
I've never had a problem with them and they're the only brand I buy. They've
been around for years, first supplying OEM PSUs for IBM in 1984. In the 23
years since they've been OEM suppliers at different times for Apple, Compaq
and several other big manufacturers.
Not well advertised and they don't have a big presence in the aftermarket
arena but you won't go wrong with an AcBel.
