E-Power Silent Engine 550W Power Supply (PSU)

Specifications and Features

When picking out a power supply most people forget that a power supply is the heart of any personal computer and needs to be stong and well made. Taking into consideration that leading enthusiast motherboard companies like DFI are requiring at least a 500W power supply for systems running a high end processor and nVidia 6800 Ultra’s or higher. If you are upgrading that computer you built or bought two or three years ago chances are your power supply will not meet today’s power supply requirements. Today we are taking at look at the E-Power EP-550P5-T1 ATX12V 550W Power Supply. This power supply comes rated at 550W and features a pair of 6 pin PCI express VGA connector to support the latest PCIe graphics cards, a 4+4 pin +12V connector that can be used as an EPS connector (DFI’s latest nF4 Expert board uses an EPS connector), and to top it all off the cables feature E-Power’s EZ cable plug to make things look nice and clean in your case. Now that we are sure the E-Power Silent Engine Tiger 550W PSU has all the latest features let’s take a look and see who E-Power is.
