<--SHOP FOR A ZALMAN ZM460-APS ULTRA QUIET 460WATT POWER SUPPLY

 

PRODUCT SPECIFICATIONS AND FEATURES

From the Zalman website:

• CNPS (Computer Noise Prevention System) with Auto Control Cooling Fan
  By implementing heat-sensor circuitry that controls the cooling fan's speed (rpm) in relation to the temperature within the power supply, noise has been greatly reduced. CNPS (Computer Noise Prevention System) refers to a system that reduces a conventional computer's noise (30dB or more) to an inaudible level (20dB or less). In order to create a true noise-free computer, Zalman's other noise-free products should be used together with this product.
• Improving Power Factor & Eliminating Harmonics through Active PFC
  By implementing Active PFC, the power factor (PF) is improved from 75% (Passive PFC) to 96% (230VAC, Full load), while harmful harmonic frequencies are reduced below regulatory requirements.
• High Efficiency Design
  Designed with a high switching frequency and low power-loss circuitry, the efficiency of this product exceeds 80% (230VAC, Full load).
• ATX "20+4"-Pin Main Connector
  ATX "20+4"-Pin main connector broadens mainboard compatibility.
• ATX12V CPU (4-Pin) & EPS12V CPU (8-Pin) Connectors
  Use two ATX12V 2 (4-pin) connectors together to form an EPS12V CPU connector (8-pin).
• PCI Express Graphic Card Power Connector(6-Pin)
  PCI-Express graphics card power connector is provided to high-end graphics card support.
• EZ Grip Connectors for ODD & HDD
  EZ Grip Connectors for ODD & HDD for easy connecting and disconnecting of the plugs.
• Dual +12VDC Output
  Two +12VDC rails output up to 30A combined, providing more stable power to high-end systems.
• Sleeved Cables
  All power cables are sleeved for easy cable management and improved air circulation in the computer's case.

 

PRODUCT COMPOSITION

Due to the recent release of this product, availability in the US is a bit spotty. However, the ZM460 should become easier to find in the near future at a price point hovering somewhere around $110 US. Let's see what the folks at Zalman deliver in exchange for the consumer's hard-earned dollars.

Clockwise from the top, we can see the customary wall power cord, a PCIE 6-pin Y-adapter, a SATA power adapter and Zalman's interesting ZM-MC-1 multi-connector. Also included are four Velcro cable ties, mounting screws and a multi-language manual.

With the bubble-wrap removed, we get our first look at the ZM460. Eschewing any visual bling, Zalman has opted for a more low-key, workmanlike appearance. As we'll see later, that large bundle of cables is hiding some nice surprises.
