Your review caused me to hit eBay in search of one - snagged for under
$30.00 shipped! Tell me where else one can grab a PSU with aPFC and
full-range AC sensing/compensation for that money? And there were
several that could be had for around that figure. Too bad they didn't
read your mini-review first - could have saved them buying an
unnecessarily overpowered and expensive PSU. This can easily handle over
90% of PSU needs in recent systems (12V dependent) - plus you hit the
efficiency sweet-spot with most normal systems. As far as I can tell,
this unit is very similar to Antec's Earthwatts unit of the same power
and the similar SuperSilencer, Seasonic-branded units.
A few things you may want to add to the review - verify with your own
1- The main filter capacitor looks to be Rubycon - good and the same as
the Seasonic branded unit in your pics.
2- The fan in my unit had the fan mfr's label on the rotor of the fan
instead of the frame. It was off-center (as I've found that most applied
to the rotor are) and it's massy enough (relative to the mass of the
rotor) to contribute to vibration and noise in proportion to the speed
of the fan - the more it would ramp up in the PSU due to heat, the more
you will notice the additional noise from the eccentric label.
I initially noticed this "feature" on a fan that came with a Silverstone
CFP51 HDD cage that I had here for review (
). I could both feel and hear the
contribution of the label to the noise of the fan. Tony Ou said SPCR
commented on the same fan as part of some review here - perhaps a case.
I don't think Silverstone will be sticking any "unbalance weights" on
their fans any more...
I suggest that you remove that rotor label (carefully so as not to
damage the bearings) and revisit it as it was quieter than most of the
fans I've had here (including Yate Loon) especially LED units. It also
has a 52 Ohm resistor internally which can be bypassed if you need a fan
with more output - the resistor drops the actual fan voltage to ~8V. May
be nice to use a bypassed unit with a fan controller so you can have
quiet as you need and yet more air when needed. Just the same way I use
my Sanyo Denki that is capable of over 100 CFM and very quiet at 5V
while still moving some air (120x38mm).
In any case, I now remove all labels from fan rotors (the Y-L come with
them too) and I can notice the difference more or less depending on
degree of eccentricity and mass of the label. It is a shame that the
engineers go to a lot of trouble creating molds to yield nicely balanced
fan rotors, and then their marketers stick labels all over the place,
willy-nilly. In the case of the SU-380 it was Antec who had the Adda
label put on the rotor so they could have their own label put on the
frame where the users could see it peeking out from inside the PSU -
really stupid! I hear that SPCR is close to Antec - so give them this
piece of my mind for me.
Thanks for saving me a BUNCH of money on a new PSU - I have been running
my machine with my ancient backup Sparkle FSP-250ATX with only 13A on
the single +12 rail. A couple days ago when the local temps went
freakishly (for central NY) into the mid-80s the poor thing started to
heat up a bit to where I could actually hear the fan - their noise
killer feature really works when the unit is cool. I know if I were to
add another HDD, it couldn't handle it. Got this one just in time.
