Description

Flat cables and a single +12V rail for an easy build

Flat cables bend more easily and fit behind the motherboard tray better than round ones, which makes them simpler to hide. With a single +12V rail there is no need to think about splitting the load between connectors. Protection against over-current, overload, over- and under-voltage, short circuit and overheating cuts the power if something goes wrong and keeps your components safe.

Who this power supply is for

The Gigabyte GP-P550SS fits a home or office PC or an entry-level gaming PC whose graphics card needs no more than two PCIe 6+2-pin power plugs. It is a sensible replacement for an ageing power supply, as its ATX dimensions suit a standard case. The black housing blends into a classic dark build.

Questions & answers

Does it work on the Estonian mains?

Yes. The input voltage range is 155–240 V at 50/60 Hz, so a 230 V network is fine. It cannot be used on 110–120 V networks such as in the USA.

Can unused cables be removed?

No, the unit is non-modular and every cable is permanently attached. The flat cables are, however, easy to fold and tie up behind the motherboard tray.

Which graphics cards can it power?

The unit has two PCIe 6+2-pin connectors and up to 45.8 A on the +12V rail. Check the PSU wattage recommended by your graphics card maker: if it is up to 550 W and the card needs no more than two 8-pin plugs, this unit fits.
