Additional Information

Active PFC for Improved Power Factor & Reduced Harmonics
By implementing Active PFC(Power Factor Correction), instead of Passive PFC with a Power Factor(PF) of 75%, the PF is improved up to 99% while harmful harmonic frequencies are reduced to meet the Line Harmonic Distortion Requirement of EC61000-3-2 Class D.

WEEE & RoHS
Complies with WEEE & RoHS environmental directives of the European Union.

• WEEE (Waste Electrical and Electronic Equipment)
• RoHS (Restriction of Hazardous Substances)

This power supply is 80 PLUS® Bronze certified with 82% minimum / 88% maximum efficiency (230VAC, Typical Load) incorporating a high switching frequency & low power-loss circuitry design, and guarantees higher efficiency compared to uncertified products. 80 PLUS® is an energy efficiency certification program administered by Ecos Consulting of the U.S.A

The Power Supply is high quality, no question about it. The sleek silver finish looks great and all the cables are nicely sleeved with rubber ends to keep them tidy. Moreover, in testing all of the rails were incredibly tight which makes for a very stable unit. Read the full review at xsreviews.co.uk

Cautionary Notes

1. Plugging the main power connector P1 into the motherboard while the product is connected to the AC power source may result in damage to the motherboard.

2. Make sure that the connectors are connected to their designated locations, and that the connectors are not oriented in the wrong direction when connecting the DC output connectors.

3. If the Power On light fails to light up when the main power button is pressed after completing the installation procedure, then some devices may be plugged in incorrectly or the motherboard may be faulty.
