A Detailed Look
The ABS/Tagan BZ800W power supply features a scratch-resistant black-matte finish, which provides a good background for the chrome fan guard and cable connectors. The enclosure is 160mm (6.3”) deep and uses a single 135mm fan on the bottom for cooling.
The large cooling fan (RL4B B1352512HB) incorporates four blue LEDs and has 9 clear plastic blades. This is a high-speed fan that uses ball bearings. To help keep things quiet, the fan speed is automatically controlled by the internal PSU component temperature (speeds up as the combined load and temperature increases).
As we mentioned earlier, one unique feature found on the BZ800 power supply is a small slide-switch on the back panel that can be used to select either Normal or Turbo operating mode for the +12V outputs. Tagan claims “Turbo Mode” offers higher power to heavy-loading devices and “Normal Mode” for stable DC output. IMHO, that’s just marketing gibberish. In reality the little red switch appears to either enable or disable current limiting on the six +12V outputs. This allows the unit to meet the current design standards by providing current limiters on the +12V outputs but allows the end user to disable current limiting, resulting in a single, high amperage +12V output.
Another of the BZ800’s unique features is the use of patented PipeRock connectors for attaching the modular cables. How ABS/Tagan can claim a patent on these legacy connectors is beyond me… (they look just like the connectors used on vintage audio and radio equipment:) Regardless, they do make for a very secure connection. The connectors and modular cables are color coded and physically keyed to prevent accidentally plugging a PCI-E cable into a Molex connector.
The ABS/Tagan BZ800W power supply comes with a full assortment of cables and connectors. In addition to the modular cables, the main motherboard power cables are hard-wired into the main chassis. The cables are covered with braided plastic mesh sleeving all the way to the end connectors and measure approximately 20” long.

Mine died after 10 years of use, i’ll try to fix it. It have been a very reliable power supply. And it was rough to choose a replacement psu, since every psu novaday is very dull compared to the tagan BZ800 For the drama, this psu got high voltage sparks betwen a 1ohm resistor on the high voltage side. The spark have dig a hole on the varnish and copper, and went through 5mm air gap to the next voltage regulator. The main circuit breaker have done his job, and everyone have saved the computer. The computer is still working great and i was ok tier to find the corsair shift, who seeem to be the last one to give a little bit of originality Novaday. The Tagan bz800 was a great psu and i hope i’ll fix it
