"This PSU features PowerGuard & Advanced Protection Guard function to monitor the PSU itself. With tri-color LED, PowerGuard tells you the current PSU status. In case of abnormal situations, the power supply will automatically turn off to aviod potential danger to itself and other system components."

 

Sapphire Pure 1250W PowerGuard Indication
LED
On/Off Switch
 
OFF
OFF
No AC Input – Turn the I/O switch to the ON position.
OFF
ON
No AC Input or PSU malfunction – Check if AC cable is firmly plugged into wall outlet and AC inlet. If LED still does not turn to orange light, then contact SAPPHIRE service center.
Orange
ON
PSU normal and system in standby/sleep mode.
Green
ON
PSU normal and system operational.
Red
ON
System abnormal, protection circuit activated.
If you push the system power button, and PSU refuse to turn on, the LED turn from orange to red light:
-Short Circuit protection activated.
-Completely check if all connectors are correctly inserted, and clean the chassis to prevent undesired objects, which might short circuit any device/terminal.
If during system operation, the PSU suddenly shut down:
-Touch the PSU housing and check if it is hot. If yes, wait till cool down and restart the system to see if all system fans and PSU fan are running. Add or replace the system fan if required.
-If same situation repeat, recheck if all connectors are well connected to system, or redistribute certain drives/PCI-E power to different 12V rail connector.

Features:

Exactly as printed on the box.

  • EPS 12V v2.92: Ready for most upcoming CPU generations by using 12P sockets for possible connector changes and complies to the latest EPS 12V PSU design guide for compatibility. Also optimized for multiple core and workststion processors such as the Intel Xeon and AMD Opteron.
  • 80PLUS BRONZE Certified: Compliant with 80 Plus Bronze standard. Efficiency up to 91% @ 230VAC helps reduce power consumption and electricity fare.
  • 8 PCI-E 2.0 Power Connectors: Supports PCI Express 2.0 SLI or CrossFire X technology and next generation graphics cards with 6+2 (8P) PCI-E connectors. 8 PCI-E connectors(upgradeable to 10 by optional modular cables) can easily drive multiple graphic cards with multiple screen graphic workstations.
  • Worldwide Power Support: Auto-Adjustable for global voltage support: 100VAC~264VAC (Maximum Range).
  • Active PFC: Active PFC improves the power factor up to 0.99, greatly reducing AC harmonic distortions and save energy.
  • Complete EMC Solution: Full-scale electromagnetic filtering protects your system against radiation interferences.
  • Post Cooling Design: Special power fan post cooling design exhausts the remaining heat inside the system for 30~60 seconds and prevents heat surge after PS-OFF to extend component lifetime.
  • Advance Protection Guard: Advance Protection Guard IC with over loading / current / voltage / temperature, under voltage, short circuit, surge and inrush current protections. Plus additional LED links with protection IC to indicate PSU status.
  • Circular LED Power Fan: Patent design circular LED 14cm magnetic bearing cooling fan with intelligent thermal control.
  • Heavy-duty Components inside: High quality Japanese Electrolytic Capacitors / HI-FLUX core / Massive Aluminium Heat Sink / Solid State Capacitors / 120% over power transformers ensure maximum performance @ 50°C extreme environment.
