Hi this is my first post, and I hope I'm posting it in the correct place, so I recently bought a Gigabyte GT 640 2 GB DDR3 for my old system that I use for media consumption (which has a IPIBL-LB (Benicia) as motherboard) in the guest room, but when I plug it in the PCIe 2.0 16x the card doe not power up, and the minimum power requirements are 350 Watts and I'm correctly using a 300 watt so it should work, since a couple of moths before I bought an Asus Radeon HD 6670 for the same system mentioned in this post, and for this card the power requirements were 450 Watts but it still powered up and run just fine. So if any advice or idea, please let me know, I would really appreciate it.
Thanks.
Bye.
P.S. Thanks for replies.
