Antec 550W HE PSU
[Page 6 – Ultimate PC Reviews]
Permanent Cables:
There are three permanent cables on this modular power
supply. The EPS12v (8 pin), ATX Cable (20/24 pin), and
the 12V ATX (4 pin). The EPS12v cable should be used
when possible, if there is no connector on the
motherboard for this cable, the 4 pin 12v ATX cable
should be used. The ATX cable is not optional; it needs
to be plugged in! I found that the 24 pin ATX cable had
quite a neat idea on the connector. For systems that do
NOT use 24 pin, you can simply slide off the 'extra' 4
pins that are on the connector.
Modular Cables:
There are seven modular cables:
Molex Connectors *2, Floppy Connector *1, Pci Express
Connectors *2, SATA Cables *2.
In total there are 6 molex connections, 2 floppy
connections, 2 pci-express connectors, 4 SATA
connectors.
Stress Testing:
Tests were made to see how good this power supply
actually is. I used a multi-meter to record results, Idle
results are normal pc usage - internet browsing, and
standard background applications. Load was tested with
prime 95.
Results:
Idle: 3.3v: 3.31 / 5v: 4.99v / 12v: 12.00
Load:3.3v: 3.31 / 5v: 4.99v / 12v:11.96
