FSP DAGGER PRO 550W

FSP Group is one of the few actual power supply manufacturers and can be found providing OEM services for a number of other brands at various times including OCZ, Zalman, AOpen, Antec, SilverStone, Super Talent, Sigma, and many more. This wide distribution of power supplies by FSP is not surprising given that it has been in business since 1993 and is one of the top 10 producers of power supplies in the world. For this review, we are looking at one of FSP’s SFX power supplies in the guise of the DAGGER PRO 550W.

How Sharp Is This DAGGER?

The DAGGER PRO 550W is not the first power supply we have seen from FSP nor is it the first SFX power supply we have seen from FSP. It is, however, one of the smaller capacity units we have seen from FSP here at TheFPSReview. Indeed, we rarely see units this small in capacity no matter the form factor. The last one that we saw that was close to this capacity the FSP SFX PRO 450W and that unit definitely had some good points and some not-so-good points. However, most of the time those issues traced back to the SFX form factor. Now, before moving on, what does FSP have to say about this unit:

The FSP DAGGER PRO features with standard SFX size and included ATX adapter bracket to help users easily install an SFX power supply into an ATX, Micro-ATX or Mini-ITX chassis. With this compact size but comes with powerful output, especially the +12V single-rail offers VGA cards full power individually and to avoid any overloading conditions. Besides, the fully modular and all black cable design save your system an optimal airflow space and easy to make a cable management for a polished look. DAGGER PRO series lineup 2 new wattage now, there are 4 different power output options to choose from 550W, 650W, 750W and 850W.

Let’s move on now and see what we can expect when a user purchases the FSP DAGGER PRO 550W power supply in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
