Hi,
I would like to post a review:

Corsair HX Series 620HX 620 Watt Modular Power Supply Review

"This power supply would be ideal for anyone looking to build a multi
core system with two video cards. It also is SLi Certified for up to
two GeForce 7800 GTX GPU's, but I am sure that it can handle more than
that. It also has an abundance of power cables, ten molex and eight
SATA power connectors. The fan is also extremely quiet. At around $120,
this power supply is priced adequately for a high quality 620 Watt PSU.
Overall, this is an award winning power supply and should be purchased
by anyone looking for efficiency, amazing output performance, modular
cables and a trusted brand name."
