High Power 620W PSU

INTRODUCTION

The backbone in every good system is the PSU. If the PSU fails to provide enough power it doesn't matter how good the rest of the hardware is as the system still will be unstable.

Today I am looking at a PSU from High Power that on paper promises a lot: three 12V rails, Active PFC, >80% efficiency and a extremely low noise level. With its 620W it should be sufficient for even demanding systems as long as it can manage to produce stable and clean power.

HIGH POWER – THE COMPANY

Most probably you haven't heard about High Power before. At least I hadn't. From what I can see on their website they are based in far east and they make power supplies and some cases. They are mainly a OEM and let other brands put their name on their PSU's but they also sell some under their own name. I have not seen much about their PSU's on the net so it is fun to be able to test one of their PSU's.

FEATURES AND SPECIFICATIONS

The High Power 620W PSU is a PSU with lots of nice features.

• Active PFC with auto voltage switching
• Triple +12V output rails
• Support up to 4x S-ATA hard drives
• Dual 8cm ball bearing fans (front and rear) for max. cooling.
• Integrated real-time wattage meter
• Easy Swap connectors
• Gold Plated Terminal to ensure better conductivity between power supply connectors and peripheral sockets.
• Supports ATX, BTX and EPS (20+4 pin main power and 4x4 pin +12V connectors)
• Server grade design and manufacturing
• nVidia® SLI Certified and ATI Crossfire Ready

The integrated wattage meter is the most visible cool feature but the rest of the features also are nice.

The specifications of the PSU are:

DC Output:

• 180W: 5V (30A) and 3.3V (28A)
• 500W: +12V1 (16A), +12V2 (25A), +12V3 (17A). +12V1 and +12V3 combined max 300W
• 6W: -12V (0.5A)
• 12W: +5VSB (2.5A)
• Maximum efficiency: 84%  

On paper this PSU should handle a lot of peripherals.
