400 W AT power supply
The myVolts Atx400W is a 400 W AT-type power supply built for low-energy desktop systems. It delivers power through a 20 + 4 pin motherboard connector, a 4 + 4 pin CPU connector, two fan headers and a 6 + 2 pin video card connector. A 1.1 m mains cord is included in the box.
Basic desktop builders and office upgrades
This unit suits builders assembling a quiet, low-consumption office PC or replacing a failed AT supply in an older chassis. It is not for systems that require active PFC, efficiencies above 80 %, or higher wattage for multi-GPU configurations.
Straightforward AT installation
The keyed connectors and clear labelling make installation quick and effective for anyone familiar with AT wiring. The 115/230 V manual switch must be set to match the local mains voltage before power-on; an incorrect setting will prevent operation or damage the unit. The thermal sensor controls the 12 cm fan speed automatically, so no software setup is required.

Soalan tentang produk ini
Does the power supply include a mains lead or must I supply my own?
The box contains a 1.1 metre mains cord, so no separate cable is required.
Will the 20+4-pin ATX and 4+4-pin CPU connectors fit an older AT-style motherboard?
This unit provides ATX-style connectors (20+4-pin main, 4+4-pin CPU); an AT motherboard needs an adapter, which is not included.
How can I verify the fan is responding to temperature after installation?
The built-in thermal sensor varies the 12 cm fan speed automatically; listen for the fan to spin faster as the supply warms up.
