Chieftec CTG-600-80P

This is the senior model in Chieftec’s entry-level A80 series which ranges from 350 to 600 watts.

The CTG-600-80P is shipped in a small box that turns out to be unexpectedly heavy for its size (and the product price, too). The box design is the same for every model in the series. You can only identify the specific model by the mark next to it in the list of model names.

The PSU comes with a mains cord, mounting screws and a user manual.

The manual covers two PSU series from Chieftec: A80 and A85.

Exterior Design

The CTG-600-80P has an unremarkable appearance: an unpainted case with thin panels and a 120mm fan shifted slightly off the center. The exterior matches the price, actually. The lower-wattage HIPRO is the only PSU in this review to be cheaper.

There’s an On/Off switch on the honeycomb back panel.

There are four holes in the panel with cables but they are too small to be vents. The PSU lacks any other openings in its case.

Circuit Design

Combined with its specs, the interior design of the CTG-600-80P helps easily identify its actual maker. It’s Sirfa.

There’s nothing extraordinary about the interior. The PSU lacks dedicated voltage regulation and is generally not as advanced in its circuit design as newer solutions, like the above-discussed Antec based on a FSP platform.

The CTG-600-80P features active power factor correction but is only designed for 230V mains.

The combined PWM and PFC controller is implemented as a FAN4800IN chip from Fairchild Semiconductor.

A PS224 chip is responsible for monitoring and protection.

The CTG-600-80P employs rather high-quality Teapo capacitors.

Cables and Connectors

The CTG-600-80P is equipped with the following cables and connectors:

  • One mainboard cable with a 24-pin connector (48 cm)
  • One CPU cable with one 8-pin and one 4-pin connector (58+15 cm)
  • One graphics card cable with two 6+2-pin connectors (43+15 cm)
  • One cable with three PATA power connectors and a floppy-drive plug (42+15+15+15 cm)
  • Two cables with three SATA power connectors on each (44+16+16 cm)

The mainboard cable is sleeved. Its solid connector doesn’t have a detachable 4-pin part for compatibility with old mainboards. That’s okay because modern products have been using 24-pin power connectors for many years already.

The free-flying pair of additional pins for the first graphics card connector looks odd. This connector may even seem to be of the 6-pin variety at first sight.

Overall, the selection of connectors is sufficient for a PSU of that wattage and the cables are long enough, except for the CPU cable with 8-pin connector which may turn out to be too short in some system cases with a bottom PSU bay. We guess a 4+4-pin connector on a 65 to 70-centimeter cable would be guaranteed to match any system case.


The CTG-600-80P cannot support a high load on the +12V rail: only 504 out of its full 600 watts. In fact, the PSU can hardly work at loads higher than 550 watts because it’s virtually impossible to find about 100 watts of load for the +3.3V and +5V rails in a modern PC.

The rest of the specs are quite conventional. The combined load capacity of the +3.3V and +5V rails is 150 watts. The standby source can deliver 2.5 amperes.

The CTG-600-80P lacks any official 80 PLUS certification although we can see a badge on its label stylized to look like that certificate. In fact, the self-made badge has the same meaning because the manufacturer promises the PSU to be over 80% efficient in 230V mains.
