Introduction

When you think of high end performance memory, undoubtedly the name Corsair pops into your head, while names like Dominator and XMS jump onto the tip of the tongue. However RAM is not their only concern with cooling options and power supplies being part of their repertoire. Today I have with me their flagship model PSU, the HX620w; let's see how it does.

Features

• Supports the latest ATX12V v2.2 and EPS12V 2.91 standards and is backwards compatible with ATX12V 2.01 systems.
• Guaranteed compatibility with dual-GPU configurations.
• Double forward switching circuitry design offers high efficiency, up to 80% under wide load range.
• Active Power Factor Correction with PF value=0.99 provides clean and reliable power to your system.
• Universal AC input 90~264V automatically scans and detects the correct voltage. No more hassle of flipping that tiny red switch!
• Ultra quiet 120mm double ball-bearing fan delivers excellent airflow at an exceptionally low noise level by varying the RPM in response to temperature.
• Guaranteed to deliver rated specifications at 50ºC.
• Triple 12V Rails provide independent reliable power to the CPU, video card and other components with a combined rating of 50A (40A on 520W) maximum! Advanced circuitry design that automatically enables power sharing between the triple +12V rails in an event of overload on any single +12V rail.
• Powerful +5Vsb rail with 3A rating.
• Over Current/Voltage/Power Protection, Under Voltage Protection, and Short Circuit Protection provide maximum safety for your critical system components.
• 105ºC rated industrial grade capacitors provide un-compromised performance and reliability, delivering 4 times the life span of conventional 85ºC rated capacitors.
• Enhanced modular flexible cables enable easier cable routing and increased airflow in the system.
• Gold Plated connectors provide oxide free ultra low-resistance contact between the power supply and your critical components.
• 8 Serial ATA connectors (4 on 520W).
• Dimension: 5.9"(W) x 3.4"(H) X 5.9"(L)
  150mm(W) x 86mm(H) x 150mm(L)
• MTBF: 100,000 Hours
• Safety Approvals: UL, CUL, CE, CB, FCC Class B, TÜV, CCC, C-tick.
