today we will be doing an upside down unboxing of the fsp AUM series gold 400
power supply so personally I'm a big fan
of Highly efficient reasonable wattage power supplies and the reason for that
is actually outlined in a recent edition of NC Tech tips that I did and uh you
you should check that out it's called power supply y power consumption system
power consumption or something like that and um what we basically do is we take a
system we upgrade it from a very very basic configuration all the way through
all the steps up to a very high-end machine and then we discover as we go
along how much power it consumes so what we found out was we plugged in a 1200
watt 80 plus gold power supply and power consumption sucked the efficiency was no
good because we were consuming so little power from it whereas if we'd taken a
400 watt 80 plus gold power supply we
would have actually consumed less power as a whole so it's got kind of a neat
finish on it it's got a 5-year warranty it's recommended for gaming and
workstation remember you can power a decent gaming machine off a 400 wat
power supply here's the overall specs which we'll see as we open up the unit
itself fsp Maya IC multiple intelligence
ability chipset okay uh what else have we got here constant holdup control
performs continuous adjustments according to the output load in order to
achieve the best possible efficiency so this is all about efficiency as I
mentioned before it is 80 plus gold let's just go ahead and start opening up
the unit itself so the first thing we find inside is a quick start guide which
pretty much tells you not a whole
lot English is the fourth language in
here if I can even find it shows you the connectors and whatnot we've also got
four black thumb screws nice little touch an FSB case badge as well as uh
three velcro cable ties power cable is
included and then the power supply
itself uh wrapped in my favorite kind of foam so the Clos cell foam that is
really very very durable and you can see
right here this is a 400 W power supply so it doesn't have a whole lot of cables
attached but let's look at the unit itself first so it's got a goldish
blackish darkish this is a really neat powder coat finish this is actually very
similar to the finish that I have on my tj07 case my personal case I had it done
by Mountain mods it's they call it black wrinkle it's very durable completely
fingerprint proof almost scratch proof and looks outstanding it's like a matte
black but it has a little bit of shine to it almost like it has brush Strokes
in it like it was painted piece of plastic in there we've got a 120 mm
cooling fan covered by a grill it's covered by a little piece of plastic
here that'll protect that go ahead and remove that there you go now you can see the full shininess at the back we have
kind of an arrow design to The Back Grill that looks like it should provide
pretty unrestricted air flow through the back of the power supply uh Power input
power switch on both sides of the unit we
find oh hold on what's that oh that
comes off okay we find fsp branding as
well as that nice uh black wrinkle finish on the top we find the overall
specs of the unit so let's have a look here you can see it does have dual 12vt
rails that are together capable of providing up to 384 watts of power so
that is almost the full 400 wat capacity of this power
supply and then we move around to the other side of the unit where we find
more fsp branding you can see what they've done is if your Windows on the
normal side of your case no matter oh no okay it will be upside down if you go
this way so the fsp will be right side up if you install it this way around
we've got a few more of those ventilation arrows here on the front of the unit and now let's have a look at
the sleeving as well as the cables that come preattached to the r from 400 wat
so here we are we have our 20 plus 4 pin power connector you can see that uses a
a pretty decent quality sleeving on it so you can't really see the color of the
wires too much through that okay next we have our 4 plus 4 pin EPS power
connector so this is quite a long cable which is good because if you have a
bottom mounted power supply you're going to want to be able to reach the top left corner of the motherboard where that's
usually situated here we have a 6 plus2
so 8 Pin PCIe power adapter I would have liked to see an additional one of these
but you can always use adapters so we do have three Molex connectors and one
floppy connector so you could use a couple of those to get another PCIe 6
pin out of it remember this will power a decent machine right guys so even with
like a GTX 560 you'll have no problem using a 400 wat power supply and then
finally four SATA power connectors so
all of those are sleeved and then terminated individually so it looks
quite nice so let's just see if there's anything else we missed here before we
wrap it Up acoustic noise they're claiming it's whoops they're claiming
it's quite quiet even up to 100% load most power supplies you see on their
noise charts they usually kind of ramp up like this near 100% load this one
does not and in terms of efficiency because it is 80 plus gold it is peaking
up at around 90% efficiency so thank you
