Corsair VS550 550 Watt which is not 80 plus certified or
Gigabyte PoweRock Power Supply, 80Plus Certified, True 550W 550 Watt SMPS
thank you so much for the replies
Gigabyte doesn't have a 550 Watt model in the PoweRock Series.
If your looking at the GE-P450P-C2 model that one is from Gigabyte's Superb Series and is made by AcBel Polytech not CWT (i.e. Channel Well Technology). It is a 450 Watt continuous power supply unit that has a peak of 550 Watts.
The Corsair VS550 is better than the Gigabyte model because it can actually produce a continuous 550 Watts and has a much higher +12V rail capacity and it has two (6+2)-pin PCI Express supplementary power connectors.
