Product overview

FSP’s Dagger PRO 650W (model SDA2-650) debuted in 2019 as part of the compact Dagger PRO SFX line, bringing an 80 PLUS Gold, fully modular design to small‑form‑factor builds. The official specs highlight SFX12V v3.3 compliance and a cable set tailored to SFF cases.Sourcetomshardware.com

Positioned as a high_end SFX PSU, it exists to deliver Gold‑grade efficiency and tidy, fully modular cabling in tight enclosures without stepping up to pricier Platinum or ATX 3.0 units. At 650 W it suits SFX/small‑form‑factor mid‑range gaming and many high‑end GPU builds; note there’s no native 12VHPWR and no ATX 3.0 rating, so PCIe 5.0 cards require adapters. Notable: two EPS CPU connectors in an SFX unit plus a semi‑fanless fan profile. Still listed by FSP as an active product (not discontinued) as of 2026.Sourcefsplifestyle.com
