Internally the Enermax Galaxy
EGX850EWL is organized and spacious. The 135mm Silence RL4T-B1352512MB-3M fan
is detachable from the power supply PCB (12V, 0.38A) as is the 80mm
SuperRed CHA8012DB-CA (12V 0.3A) and we're pleased to see a replaceable fuse
inside the power supply. Please note though that if you do decide to replace it
(if it were to blow), you're voiding the warranty. The power supply is deigned
to operate in temperatures between 0-50 degrees Celsius and in a relative
humidity between 20-80%. A large group of aluminum heatsinks are used to cool
down components, and they are situated directly behind the 135mm fan.

potentiometers that are user accessible. The Galaxy EGX850EWL lacks these
components, so if you find the 12V rail sagging under load, there is nothing you

EGX850EWL. Build quality is generally good and the plug is EMI shielded. Both
the 80mm and 135mm fan power connectors are detachable, not soldered.
Replacing a seized fan years down the road will be
Enermax claims that the power supply is
82-85% efficient. That's a pretty lofty claim, let's check out whether the
Galaxy can live up to the hype by testing its power capabilities.
