Thanks for info and would using an box instead work also shouldn't the cards be seated well as I literally just took out the old power supply and plugged one in with the 8 pin on motherboard, one on hdd, 2 6 pins on the gtx 560ti, and also the 24 pin into the motherboard
Antec is one of the so-so branded PSU suppliers, I have one and have used that same one (BQ550) in like 3 builds.. but some of there other ones have had bad reviews, and DOA problems.. Sounds like you have a DOA unit if hooking everything up a second time dosn't solve your problems.
If it's too late to exchange it with your vender, email antec for an rma request: http://www.antec.com/index.php?page=info_contact. I've talked to them by phone before; no problems getting through to a real person, but you should be able to do this online. Just select "contact us"; my link didn't save.
