Both units are an improved version of FSP's current DAGGER line of PSUs, whereas we have advancements made in most areas including efficiency, design, and connectivity. We have a semi-passively cooled PSU with a single 92mm fan keeping it cool and a fully modular design with ribbon cables in the SFX form factor with 550W or 650W at your finger tips. But don't worry, FSP includes an SFX to ATX bracket in case you upgrade your rig in the future.

FSP's new DAGGER PRO SFX PSUs are fully SFX12V V3.3 standard compliant, with a powerful single +12V rail design that will ensure you get maximum performance to all of your components. There's 80 Plus Gold rating in both models, and with their semi-fanless design we're looking at a single 92mm fan keeping it all cool, which is impressive for such a small PSU.
