550GS / 650GS GOLD Power Supply User Manual
3. Use the screws provided with your case to install the power supply into your
computer.
NOTE:
It is recommended to install the power supply with the fan
facing down. However, if your case places the power supply at the bottom of
the case and there are no ventilation holes available, it may be best to install
the power supply with the fan facing up for greater efficiency and reliability.
4. Connect the 24-pin ATX cable to the motherboard.
5. Connect the 4+4-pin EPS12V cable to the motherboard.
(Optional)
– If you plan on
extreme overclocking
and your
motherboard supports additional 8-pin or 4-pin CPU power
connectors, connect the second 4+4-pin EPS12V cable. This is
only
needed for heavy overclocking or for Dual CPU motherboards.
6. Connect the 6/6+2-pin PCI-E cables to your graphics card(s).
NOTE 1:
Do not attempt to plug an 8-pin PCI-E cable into a 6-pin
connector without first detaching the two extra pins.
NOTE 2:
We recommend to use a single PCI-E cable to connect per
port on graphic cards if your video card requires high power such as
equipped with more than 2 PCI-E connectors 6pin + 8pin and 8pin + 8pin.
NOTE 3:
EVGA 650GS/550GS is designed for 2 or less VGA cards
installation. If you need to install 3 or more VGA cards in the system,
please choose 750W or above PSU to prevent from the self-protection
shutdown during operation.
7. Connect SATA power cables to all data drives or optical drives.
(hard drives, solid state drives, optical drives)
8. Connect the peripheral “Molex” 4-pin connectors for fans, pumps,
legacy components and other devices/adapters.
9. Connect the AC power cord to your power supply and to the wall.
Check all connections to assure a solid connection and turn the
power switch on the power supply to the ON position.
Q&A
Q: I see there are
more than 4 screw holes
on the back of the power supply, but the packaging only offers (4)
screws,
are some missing
?
A:
Nothing is missing
; you will only need to attach the EVGA power supply to the case with 4 screws.
The power supply offers more than (4) holes to
provide optimal compatibility
for today’s varied case designs.
Q: My EVGA Power Supply includes (2)
EPS cables
for my motherboard, do I need to connect up both?
A: Motherboards
only require (1) 4+4 or 8pin EPS connection
. On some models, an additional 4+4pin or 8pin
connection on the motherboard may be available for
dual CPU
configurations or for
extreme overclocking
. If your
motherboard support dual 4+4pin EPS connections, please refer to your
motherboard manufacturer’s manual
for
details on the proper function and power if the EPS connections.
Q: What is the
Dual Thermal Control System
?
A: The
Dual Thermal Control System
, when Eco mode enabled, allows the fan on your EVGA power supply to
shut off
during low to moderate operation loads. The EVGA power supply’s fan will
automatically turn back
on
when needed, based on the temperature the power supply reaches. The fan will also increase in RPM when needed,
based on the load operation being requested from the components connected. This prevents unnecessary rotation,
reduces ambient noise
levels and will
increase the life span
of the fan due to the fan not spinning when
not required.
Please Note:
If the
Eco mode
is disabled the fan will always spin, even at low loads. The fan will also
increase in RPM as needed automatically, based on the power draw from connected components
Q: What if I want to use
power adapters
for my video card(s)/motherboard/peripherals?
A: EVGA always recommends the use of
direct power connections
from the power supply to power all components.
Q: Does it matter
which end of the cable
I plug into the power supply?
A: Yes, the connections going to the power supply will not have “break downs” like the EPS (CPU) has 4+4 on
one side and full 8-pin on the other. Another example is the 24-pin cable, you can see on the PSU side it is a
total of 28 pins, where the 24-pin connection will go to the motherboard directly.
Check each cable
as it is labeled
appropriately to match the power supply side and connect only the same
“matching”
cable directly to the power
supply as referenced on each connector.
Q: I plugged everything in and the system will not POST, or goes into a boot loop.
A: Power the PSU off and double check to make sure all the power connections are firmly seated on the
motherboard and on the PSU side. If the problem persists you will want to try testing the 24-pin using the
provided PSU tester. If the PSU tests ok, then you will want to try testing the motherboard in “barebones” to get
a POST, removing everything except for the CPU and heatsink, 1 stick of RAM, 24-pin and 8-pin power connections.
Q: If I have an issue or a question, can I get support?
A: ALL EVGA products are backed by top tier warranties as well as 24/7 technical support. Support can be
