  • Full modular design keeps cable clutter low

  • 80 PLUS BRONZE certification confirms efficient conversion
  • Four SATA ports supply drives and peripherals
  • Dual 6-pin plus 4-pin CPU connectors feed graphics and processor

SFX650 modular power supply

This SFX650 unit is a fully modular power supply rated at 550W with 80 PLUS Bronze certification. It targets builders assembling compact desktops or small-form-factor servers who need reliable delivery in a tight chassis. The active PFC design accepts a wide 90-264V input range for global compatibility.

Upgrade from lower-wattage SFX units

The supply replaces older or lower-capacity SFX power supplies when a system demands more headroom for modern components. The jump is worth it when the previous unit cannot sustain peak loads or lacks the modular cabling needed for clean routing in a small case.

550W capacity with dual 6-pin GPU power

Four SATA connectors and two 6-pin PCIe cables comfortably handle a mid-range graphics card, a CPU with a 4-pin power connector, and several drives. The 18A output on the main rail defines the practical limit; systems requiring higher 12V current or additional PCIe connectors will exceed what this unit can provide.

Questions about this item

Does the 20+4 pin connector on this SFX650 cable reach a standard ATX motherboard socket in an MS450 chassis?

The cable uses a 20+4 pin interface designed for desktop and server motherboards, matching the SFX650 unit supplied for the MS450 all-in-one system.

Which connectors must be plugged in first when wiring this full-modular SFX650 cable set?

Seat the 20+4 pin motherboard and 4 pin CPU power cables before adding the two 6 pin graphics and four SATA drives, so the PSU can self-test on the 18 A rail.

When should the four SATA power leads on this cable be replaced?

Replace any SATA lead if the latch cracks, pins discolour, or a drive reports intermittent power during heavy 550 W load cycles.
