Bottom Line:
There's more to picking a PSU than the wattage, as explained in the first of a series of forthcoming PSU reviews.

Overview
Aesthetic Overview:
I rather enjoyed the Raid Max's understated snazziness. The
power supply is trick looking without looking annoying. It's the same titanium
finish as the Ultra and features blue lighting (albiet blue LED's as opposed
to blue UV reactive fans with UV lighting.) The Raid Max also had some nice
windows on it like the Ultra, but I think the reason why I think this power
supply looks a tad understated is because the fans are on the front and back
of the power supply and not the back and bottom, so the lighting is not concentrated
in one area.
Taking
a look at the label:
| RAID MAX RX-520XP |
+3.3V |
+5V |
+12V |
-12V |
-5V |
+5VSB |
| Max Output Current |
26A |
45A |
18A |
1A |
0.8A |
2.5A |
| Max Combined Wattage |
220W |
216W |
12W |
4W |
12.5W |
As you can see above, the Raid Max is very strong on the 5V rail and not
so much on the 12V rail. I'm not sure why Raid Max didn't put more attention
on voltage distribution. Take a look at the negative DC and 5V standby, for
example. 28.5W alone is spent on those rails. Why?
What
power connectors do we get?
The cables
are all twisted to help reduce EMI. The two "VGA/HDD" and
the ATX connectors have a shield on them.
What's funny is that if I look really close at these shields, I can see the
word "Tagan" on
them. Oops!

* = 6 of the 5.25"connectors are
typical where two of them have the EMI and ripple filtering on them.
Here's a close up of the VGA/HDD and the ATX connector.
The ATX connector
actually has a modular design that allows it to easily become an EPS12V
connector by just clipping on the extra four wires on the end (as shown.)
There's also two 2x2 12V connectors that snap together and become one
2x4 connector.
I've voided my warranty further by stripping the heat-shrink tubing off
of the VGA/HDD connector to expose the iron ferrite cores and small capacitors
used to clean ripple and reduce EMI.
So now it's time
for some testing!
