T HE A DVANCED PSU S OLUTION
The TruePower New series is A tec’s full featured li e of high-quality, reliable power supply u its (PSUs). Combi i g
cutti g-edge tech ology a d a efficie t desig , the TruePower New series is the ideal solutio for elite system
builders a d quality-mi ded e thusiasts alike. With +12V rails that are regulated to ±3%, the TruePower New series
delivers full rated power a d tight voltage regulatio .
S TANDARDS AND F EATURES
The TP-550 PSU is compatible with ATX12V v2.3 a d EPS12V v2.91 specificatio s. The TP-550 features U iversal
I put, which automatically se ses whe you co ect the power supply to a y AC power source betwee 100~240V
without havi g to worry about setti g a voltage switch. This power supply also features Active Power Factor
Correctio (Active PFC), which improves the power factor value of the power supply by alteri g the i put curre t
wave shape, which helps power tra smissio across the grid.
S YSTEM P ROTECTION
A variety of i dustrial-grade safety circuitry will help protect your computer: OVP (Over Voltage Protectio ), SCP
(Short Circuit Protectio ), a d OCP (Over Curre t Protectio ). Sometimes the PSU will “latch” i to a protected
shutdow state. This mea s that you will eed to power off the PSU a d clear the fault before it will fu ctio agai .
There are o user-replaceable fuses i your TP-550.
80 PLUS® B RONZE C ERTIFICATION
80 PLUS® certificatio is the most widely recog ized i depe de t sta dard i power supply efficie cy. A 80 PLUS®
certified power supply uses less e ergy a d ge erates less heat to stay cooler, ru quieter a d last lo ger. The
TP-550 PSU ear s the rare 80 PLUS® Bro ze level of efficie cy, mea i g that it has bee certified to be at least 82%
efficie t at a wide ra ge of operati g loads; this will lower your operati g costs a d help protect the e viro me t.

NVIDIA™ SLI™-R EADY C ERTIFICATION
A tec’s TruePower New series power supplies are NVIDIA™ SLI™-Ready certified for use with pairs of high-e d
graphics cards for superior parallel graphics processi g.
A DVANCED H YBRID C ABLE M ANAGEMENT S YSTEM
The TP-550 uses Adva ced Hybrid Cable Ma ageme t. Cables that are importa t or ma datory are co ected
directly to the PSU. There are also modular co ectors o the back of the PSU to add additio al cables as eeded.
Usi g o ly the power cables you eed will reduce clutter a d improve airflow i side your case. For the list of
co ected a d optio al cables, see Table 1.
DC TO DC C ONVERSION
A tec’s TruePower New series uses DC to DC co versio for the 5V a d 3.3V rails. The DC to DC voltage regulatio
module is the most adva ced desig , usually fou d o high-e d motherboards, to step dow DC voltage. This
module operates at 85% efficie cy, as opposed to traditio al mag etic amplifiers that operate at o ly 75%
efficie cy. A other be efit is that tra sie t respo se time is almost 100 times faster, providi g remarkably stable
power output i respo se to cha gi g loads.
P ULSE W IDTH M ODULATION (PWM) F AN
Pulse Width Modulatio tech ology allows the TruePower New series to fi ely co trol the speed of the power
supply’s fa . By usi g this method i stead of the traditio al voltage co trolled fa s, this PSU’s fa ca ru up to
50% quieter tha sta dard fa s. A PWM fa ca ru as slow as 10-15% of the fa ’s rated top speed, whereas a
voltage-regulated fa ca o ly go as low as 40%.
D OUBLE L AYER PCB
Desig ed with a double layer pri ted circuit board, the TruePower New series utilizes a low-de sity compo e t
layout to provide better airflow throughout the casi g. I additio , double layer PCBs allow for heavy-duty
compo e ts a d larger traces, reduci g electrical i terfere ce a d resista ce. This e sures greater reliability for
the power supply a d compo e ts co ected to it.
H IGH Q UALITY J APANESE B RAND C APACITORS
The TruePower New series features high-quality Japa ese bra d capacitors. These capacitors e ha ce stability a d
i crease the u it’s MTBF, e suri g greater reliability.

I NSTALLATION :
1. I stall the TP-550 PSU i to your case with the four screws provided.
2. Co ect the 24-pi mai power co ector to your motherboard. If your motherboard uses a 20-pi
co ector, detach the 4-pi attachme t o the 24-pi co ector.
Note: The detachable 4-pi sectio ca ot be used i place of a 4-pi +12V co ector.

3. Co ect the 8-pi or 4-pi ATX12V co ector for the CPU to the appropriate co ector o your
motherboard. If your motherboard has a 8-pi socket with a cover o some of the ope i gs, we
recomme d that you remove the cover a d use the 8-pi co ector.
Note: Please also refer to your motherboard user’s ma ual for a y special i structio s.
4. Co ect the cables from the cable pack to the socket o the power supply as eeded. If you are goi g to
plug the additio al PCI-E cable i to the PSU, it should go i to the red socket. If the red socket is ot bei g
used for PCI-E, the it ca be used for a other cable from the pack that accompa ied the PSU.
5. Co ect the AC power cord to the power supply AC i let. Please be sure to use the heavy-duty cord
supplied with your TP-550. Tur the switch to the “|” positio after you have co ected all the devices
a d are ready to tur o your computer.
