Seasonic G Series 550W Power Supply review

Seasonic are using an ADDA AD1212MB-A70GL fan. This is a ball bearing unit rated at 0.33A/12V. This is identical to the fan used in the G360 unit.

The unit follows a clean layout with several rows of heatsinks separating the components.

The G550 is using a high grade Nippon Chemi Con capacitor, rated 390 µF x 420 V @ 105c. Seasonic are using high grade Japanese capacitors in the secondary stage from Chemi Con and Rubycon, all rated to 105c.

The cables are fully sleeved into the chassis and tied into position. This should help resolve any concerns with long term fraying.

    What about the 650W? that has 4 PCI e connectors. seems the best choice for a little futureproofing. all the rest only have 2 or 1 PCI connectors.

    Apart from that, these seem good value.
