Server-grade ATX power supply

The Supermicro PWS-668-PQ delivers 668 W from a single PS2 form-factor unit with a 24-pin ATX main connector. It is built for workstations and desktops that require reliable multi-output power in a standard enclosure. The 80 Plus Platinum rating confirms high efficiency across typical load ranges. This unit suits builders who need server-class components without redundant architecture.

Sustained 668 W output

The supply provides continuous rated power rather than a short burst, with +12 V rail capacity of 54 A and +5 V rail capacity of 20 A. The +3.3 V rail supplies 15 A for legacy and auxiliary circuits. Efficiency remains high during extended operation thanks to the Platinum certification. Systems drawing near the maximum for long periods will stay within specification.

Thermals noise and power draw

Universal 100–240 V input at 50/60 Hz allows worldwide operation without switching. The 8 A input current at low line keeps branch-circuit demand moderate. Platinum efficiency reduces waste heat, so internal temperatures and fan speed stay lower than less efficient units under the same load. Dimensions of 5.91" x 3.39" x 7.28" fit standard ATX bays.

Perguntas sobre este artigo

How much heat and noise does the 668W 80 Plus Platinum unit produce under continuous load?

The 80 Plus Platinum rating means the supply runs at high efficiency, so it draws less power from the wall and generates less waste heat than lower-rated units, keeping fan speeds lower during all-day operation.

Does the 24-pin ATX connector on this supply plug straight into a standard motherboard without extra cables?

Yes, the unit provides a native 24-pin ATX output plus 20 A on the +5 V rail, 54 A on the +12 V rail and 15 A on the +3.3 V rail, matching typical desktop and workstation board requirements.

Will the 5.91 x 3.39 x 7.28 inch PS2 form factor fit in the same chassis as my older ATX power supply?

The dimensions follow the standard PS2 footprint used by many legacy server and workstation cases, so it should occupy the same mounting space as an older ATX unit of the same form factor.
