Value and Conclusion

  • The SAMA FTX-800-2 is only available in Asia and is priced at close to $200.
  • Efficient
  • Low ripple at +12V
  • Japanese caps
  • Sanyo Denki fan
  • Silent operation under normal operating conditions
  • Over Temperature Protection that actually works (however, it has a low triggering point)
  • Fully modular
  • Individually sleeved cables of high quality
  • Impressive looks
  • Cannot deliver full load at over 46°C ambient (OTP kicks in)
  • Very low hold-up time (combined with a long power-good signal)
  • High inrush-current
  • Single EPS connector
  • Aggressive fan profile
  • Lacks a semi-passive mode
  • Rather low PF readings (with 230V input)
  • 3.3V performance in Advanced Transient Response tests
  • Increased EMI noise
  • 3-year warranty
This PSU, SAMA's entry into the high-end category where companies like Super Flower, Seasonic, and CWT are strongly represented, obviously addresses enthusiast users. We should remind you that a few years ago, Super Flower, one of the best OEMs today, was an unknown to most users. However, once it chose to go worldwide while developing interesting platforms and cooperating with, mostly, EVGA, its name became widely known. Such might also happen to SAMA if it manages to keep quality high while cooperating with large PSU brands. The PSU I evaluated today has many strong points, but it has enough negative ones as well. This is SAMA's first try at this particular category, so mistakes are unavoidable. Now that they have a detailed report on the problems their unit suffers from, it is up to them to at least fix the most significant ones in order to deliver a fine platform that is capable of meeting the competition eye-to-eye. This unit's most severe problem is its ridiculously low hold-up time, which, to make matters worse, is accompanied by a very long power-good signal. SAMA obviously knows of this issue since its engineers built the platform, so there is no excuse. The fan profile is also very aggressive, and the lack of inrush-current protection is something I cannot find a good reason for. The over-temperature protection's triggering point is also very low for a PSU that has an official 50°C rating, while the single EPS connector is a major omission in a unit with a capacity of 800 W.

Now that I have listed the bad points, it is time to mention the good ones as well. I usually don't pay attention to a PSU's external design, but SAMA did a good job since the FTX-800-2 easily differentiates itself from the competition in terms of looks. The rose-golden aluminum plates on the unit's sides have an amazing finish, and the fan grille looks nice and offers good airflow. Since this is a Titanium unit, efficiency is definitely among its strong points, and the same goes for ripple suppression, which is quite good. The fully modular cabling design is also a big plus, along with the Japanese caps and quality Sanyo Denki fan. SAMA put a lot of effort into making this unit very reliable, which inevitably makes me wonder why it only comes with a three-year warranty where all other premium quality PSUs come with five, seven, or even ten years. To wrap up, if SAMA manages to work on the issues I found, the FTX-800-2 will be a strong candidate for many companies looking for alternative OEM options in the US and EU. As I see it, the most challenging problem is to increase the hold-up time while maintaining Titanium efficiency.
