ATX12V v2.0 Power Supply Includes Universal Input and Active Power Factor Correction (PFC) Models: NEO380 and NEO480 NeoPower power supplies include Universal Input and Active PFC. Universal Input allows you to connect NeoPower to any standard power circuit between 100~240V, without having to worry about setting a voltage switch. Active PFC improves the power factor of the power supply by altering the input current wave shape. This results in increased energy efficiency, reduced heat loss, prolonged life for power distribution and consumption equipment, and improved output voltage stability. NeoPower also includes dual +12V output circuitry, which delivers safer and more reliable output to your system's components. NeoPower also features a variety of industrial-grade protective circuitry: OCP (over current protection), OTP (over temperature protection), OVP (over voltage protection), OPP (over power protection), UVP (under voltage protection) and SCP (short circuit protection). Note: NeoPower's active PFC circuitry complies with European standard regulation code EN61000-3-2. NeoPower includes an advanced temperature-response system that provides an optimum balance between noise reduction and cooling. The power supply fan will always run at the lowest speed possible for existing load and conditions. The result? NeoPower will run considerably quieter than power supplies with traditional thermally-controlled fans. NeoPower can also control the speed of your system case fans. You'll find two dedicated fan connectors (marked "Fan Only") to which you can connect your system case fans. NeoPower's circuitry will then regulate your case fans, further reducing system noise. Note: Please don't connect more than three external fans to the "Fan Only" connectors. If you need more cooling power than that, you can connect your case fans to the regular 4-pin peripheral connectors. But that setup won't be as quiet as our recommended setup. NeoPower also includes a 3-pin fan signal connector. If you connect it to one of the fan connectors on your motherboard, you can monitor the speed of NeoPower's fan through your motherboard BIOS or through the monitoring software that's included with your motherboard. Note: The speed of the 120mm fan may be as low as 1000 RPM when temperatures are low. At these speeds some motherboards may not be able to properly detect the fan speed and may generate false warning of fan failure. Please refer to your motherboard manual for proper fan monitoring set up. Power Switch: NeoPower includes a main power switch. Make sure you turn the switch to the ON ( I ) position before you boot up your computer for the first time. Normally, you won't need to switch to the OFF (O) position, since the power supply includes a soft on/off feature. This lets you turn your computer on and off by using the soft switch on your computer case. If your computer
crashes and you can't shut it down using the soft switch, you can switch the main power to the OFF (O) position. Advanced Cable Management System NeoPower features Antec's advanced Cable Management System. It allows you to use only the power cables that you need, thereby reducing clutter and improving airflow inside your case. Inside the package, apart from a power cord, you will find the following (see Photo 1): NeoPower unit. On the front of the power supply, you'll find some wires. These include: 1. The 24-pin Main Power Connector 2. The 4-pin +12V connector 3. The 3-pin fan signal connector 4. A 2-pin Fan Only socket, which should only be used with the Fan Only cable set (see #6 below) 5. Four 6-pin output sockets, which you can use for your drives and other peripherals

Three sets of wires with standard 4-pin Molex peripheral connectors at one end and a 6-pin PSU connector at the other end 8. One 24-pin to 20-pin adapter for the motherboard power connector 9. Four additional connectors, 2 Molex & 2 SATA, for optional use 10. One set of wires with one standard 4-pin Molex peripheral connector at one end and two Floppy power connectors at the other end 11. One set of wires with a 6-pin PCI Express graphic card connector at one end and a 6-pin PSU connector at the other end 12. One set of wires with SATA drive connectors at one end and a 6-pin PSU connector at the other end. Note: The SATA connectors include a +3.3V output so you can power next-generation SATA devices.
Installing NeoPower 1. Disconnect the power cord from your old power supply. 2. Open your computer case. Follow the directions provided in your case manual. 3. Disconnect all the power connectors from the motherboard and from the peripheral devices such as case fans, hard drives, floppy drives, etc. 4. Remove the existing power supply from your computer case and replace it with the NeoPower power supply. 5. Connect the 24-pin Main Power Connector and the 4-pin +12V Connector to your motherboard as needed. You will need to use the 24-pin to 20-pin adapter if your motherboard uses a 20-pin connection. 6. In the package, you'll find a set of power supply-toMolex connectors. (One of the PSU to Molex connectors is shorter than the others.) Connect Photo 2 one of the 6-pin connectors to any of the 6-pin sockets on the power supply. (See Photo 2.) 7. Connect the Molex connector to your hard disk drives or CD-ROM. Repeat as necessary. 8. If you have a SATA drive: In the package, you'll find a power supply-toSATA connector. Connect the 6-pin connector to any of the 6-pin sockets on the power supply. 9. Connect the SATA connector to your SATA drive. Repeat as necessary. 10. In the package, you'll find a power supply-to-Fan Only connector. Connect the 2-pin connector to the 2-pin socket on the power supply. 11. Connect the Fan-Only connector to your system fans. This will allow NeoPower to control the speed of the fans you've connected. Note: Do not connect the Fan-Only connectors to CPU fans. 12. In the package, you'll find a Molex-to-Floppy adapter. Connect it to a Molex connector, and connect a floppy drive if you wish. 13. In the package, you'll find a PCI Express graphic card connector. It is identifiable as the only 6-pin connector with 3 yellow wires and 3 black wires. Connect the 6-pin PCI Express connector to your PCI Express graphic card if needed. Note: Please consult the user manual supplied with your PCI Express graphic card for detailed usage instructions. 14. Optional: If you'd like to monitor the speed of the power supply fan, connect the 3-pin fan signal connector to one of the fan connectors on your motherboard. Note: You don't need to connect the fan signal connector in order for the power supply to work. 15. Connect the power cord to the power supply. Note: If your motherboard requires a 6-pin AUX Power Connector, please contact Antec Customer Service at (888) 54ANTEC (North America) or +31 (10) 4622060 (Europe) to purchase the optional AUX Power Connector.

Additional Connectors The spare connectors are not intended to add additional length to the cable sets, but rather to add additional connectors to the existing cables. To add a spare Molex or SATA connector to an existing cable: 1. Measure and mark the desired position on the wire set that you want to add the additional connector to. 2. Remove the wire set from the power supply and place it on a flat, firm surface. 3. Place the additional connector under the wires with the cap open as shown. See Photo 3 (Molex) and Photo 4 (SATA). Note: When connecting an additional SATA Connector, we recommend connecting it to the existing SATA wires (5 wires) so it can incorporate the +3.3V output. This will allow you to power next-generation SATA devices. 4. With one hand holding the connector, use a flat head screwdriver to push wires into the proper notch on the connector as shown in Photo 5. a) Black Wires are Ground b) Yellow Wires are +12V c) Red Wires are +5V d) Orange Wires are +3.3V 5. Close the cap to complete the installation. (See Photo 6.)

Antec NeoPower 480

This power supply is like Neo in The Matrixits truly The One
Once nothing more than an also-ran in the highly contentious power supply market, Antec has improved by leaps and bounds in recent years. The latest feather in the companys cap is the NeoPower, a 480-watt beauty thats beyond reproach. The NeoPower certainly looks impressive. The sleek, charcoal nish exudes sophistication, and the thermally controlled 120mm intake fan provides adequate ventilation at whisper-quiet volumes. The convenient modular cable system allows unused power cables to be disconnected from the PSU so they dont clutter up your case. And while most power supplies have a single 12V power rail, the NeoPower sports two; according to Antec, this ensures a more reliable supply of power when demand is high. Sounds good, but we were a bit skeptical about how well this scrappy comer would hold up under close scrutiny. Fortunately, the NeoPower passed our load test with ying colors, and achieved a power factor rating of 97 percent thanks to its active power factor correction. Even our toughlove voltage sag test couldnt make the NeoPower break a sweat. When we dropped the input voltage to 60V, the output voltage didnt budge from its starting point of 11.92V. In terms of connectors, the NeoPower is about as future-proof as it gets. Aside from an abundance of standard four-pin peripheral power connectors, this PSU also includes support for Serial ATA, PCI Express,
and ATX 2.0. If youre a rabid upgrader, youll nd no better PSU to put at the heart of your system. Antec even tossed in two fan-only power connectors that dynamically adjust the speed of your fans based on case temperature. Were disappointed that Antec didnt braid or sleeve all MAXIMUMPC the power cables for a more FIREWALL professional look, but thats a The NeoPower has it alloutstanding quality and triviality.

VERDICT

OCZ PowerStream 520ADJ
The company famous for its high-speed memory leaps into the PSU fray
Known for making memory capable of operating at blistering speeds, OCZ Technology has thrown its hat into the power supply ring with the introduction of the PowerStream 520ADJ. Housed in an attractive, glossy charcoal box, this PSU promises 520 watts of quiet, reliable power for your components. And it delivers, for the most part. The PowerStream had no problems in our load test, and its typical energy consumption of 363 watts was lower than much of the competition. However, OCZ neglected to equip the 520ADJ with active power factor correction, resulting in a disappointing power factor rating of just 68 percent. Like most of the PSUs in this roundup, the PowerStream couldnt cope with the rigors of our voltage sag test, but we were more let down by its initial output voltage of 12.27V on the 12V rail. This is well below the 12.6V maximum prescribed by the ATX spec, but its also significantly less accurate than the voltages delivered by the leaders of this pack. Overclockers may appreciate the 520ADJs inclusion of voltage pots for manually tweaking output voltages. With two variable-speed 80mm cooling fans, the PowerStream remained relatively quiet throughout testing. Serial ATA and PCI Express power connectors are present and accounted for, but sadly, the OCZs power cables are not modular, and most of them are unsleeved. On the other hand, the PSU does include two dedicated power cables intended for videocards and
hard drives. These cables are shielded and boast additional capacitors for an ostensibly more reliable supply of power, though its hard to MAXIMUMPC say how much difference these DIRTY DANCING tiny caps really make. All in all, the PowerStream Nice looks, shielded videocard/hard drive power cables, and quiet. 520ADJ isnt a bad product. But it lacks important features found DIRTY SOCKS in its more potent rivals in this No active power factor correction or modular cables; voltage accuracy could be better. roundup, and in the cutthroat power supply market, being an $130, www.ocztechnology.com also-ran just doesnt cut it.
