Solid Gear Micro PS3 300 W unit

The Solid Gear SDGR-MPS3-300 is a Micro PS3 form-factor power supply rated at 300 W. It fits compact chassis that accept the Micro PS3 standard and provides a single +12 V rail. The unit uses passive power-factor correction and a single cooling fan.

Suits small-form-factor desktop builds

Builders assembling a low-power system in a Micro PS3 case will find the connector set adequate for a basic motherboard, CPU and a few drives. Systems that require higher wattage, multiple +12 V rails or modular cabling should consider a different power supply.

Single +12 V rail rated at 15 A

The +12 V output delivers up to 15 A, which determines how much power is available for the processor and graphics card. If the combined load of those components exceeds this current, the unit will not support the build.

Perguntas sobre este artigo

How much heat and noise does the 300 W unit with passive PFC and a single fan produce when running all day?

The supply uses passive PFC and one fan, so it will draw up to 10 A at 115 V or 6 A at 230 V and exhaust heat through that single fan; expect typical office-level noise rather than silent operation.

Which cables and connectors must my build already provide for this non-modular 300 W PSU to work?

It comes with a fixed 20+4 pin main connector, one 4-pin ATX 12 V CPU plug, three SATA power leads, three 4-pin Molex leads and one floppy lead; your motherboard and drives must accept those exact plugs.

Will the single +12 V rail rated at 15 A support an older graphics card that needs a 6-pin PCIe connector?

The unit only provides a 4-pin ATX 12 V connector and Molex leads; it has no 6-pin PCIe plug, so an older card requiring that connector cannot be powered directly.
