HTPC Build (Part 2) Antec EarthWatts EA-380D PSU Review/Installation

Uploaded by HTPCDIY on 11.06.2012

Hi, this is Tom from
For my MythTV build I chose the Antec EarthWatts 380D ATX Power Supply. It's a 380 Watt
ATX12v Power Supply that is 80+ Bronze certified.
The 80+ Bronze certification means it has been tested to be at least 82%
efficient operating at 20, 50 and 100% of it's rated load.
Normal ATX power supplies are 60 to 75% efficient.
Considering this computer will be on for long periods of time the extra energy
efficiency should help pay for the additional cost.
There really wasn't much of a price difference. I bought the Antex EA-380D for around $45
Which is only about $15-$20 more than cheeper power supplies.
I haven't opened the power supply yet so let's see what's inside the box.
Four mounting screws are included.
The main connector is a 20+4pin power connector.
The other cables are a 4+4pin ATX/EPS12V connector for the motherboard,
A 6pin PCI express power connector if you're installing a high end graphics card.
4 4pin modular plugs for fans and IDE drives.
5 SATA connectors and 1 floppy drive connector.
The power supply feels solid. It's not made out of thin metal like some cheaper power supplies.
You should note that a power cable isn't included in the box.
You're supposed to reuse your existing one if you're replacing a power supply.
But if this is for a new computer you might need to buy one.
Now let's actually install the power supply in the case
When possible I like to install the power supply first because it's a bit heavy and it could
damage something if it accidentally drops
This isn't an option on all cases but the nMediaPC 6000B
the power supply mounts on the side. When installed the power button should be on
the bottom.
There aren't any guides to help you position the power supply.
You just have to slide it in and align it with the holes on the back.
An issue some reviewers had with this case was the screw holes don't always line up.
I'm having the same problem.
I start the screws by hand to avoid stripping the threads. Afterwards I finish up
with a screwdriver but i don't
tighten all the way until I've made final adjustments.
I've tried different things to get the holes to align
but in the end I wound up only able to install 3 of the 4 screws.
That shouldn't be a problem however.
The rest of the video is just me tightening screws which I'm sure you can figure out on your own.
