Hey everyone... i just built a new pc here is specs

CASE SIGMA ORCA-WB RT

MB GIGABYTE GA-MA78GM-S2H 780G RT

PSU TT | W0070RU 430W RTL

CPU AMD|A64 X2 5200+ 2.7G AM2 65N

MEM 2G|GSkillK F2-6400CL5S-2GBPQ

160G|WD 7K 8M SATA2 WD1600AAJS %
DVD BURN LG|GH22LS30 22X LS SATA

all connectors are connected fine except in not sure about the extra 4 pin 12v connector thats tied with the 20 pin connector. i was thinking maybe because its one stick of ram (2gig) everything runs(fans, neon light, dvd drive, hd drive)but no beep and nothing shows up on screen.

You should have all 24 pins connected to the mobo. The slide out 4 pins is there, in case you only need the older style 20 pin power connection. You will also need the 4 pin CPU power connection to get everything powered up. So just to recap, you'll need the 20+4pin (24 pin together) and the 4 pin CPU power connections to power everything up properly.

8800gtx w/e6600 OC'd will run on Antec 380w w/27A on 12v rail, PSU!!

I had the same issue and another person I know who builds pcs had the same issue. No post. Beep codes were nothing like what was printed in troubleshooting section of manual. I decided mobo was defective and returned it. After two long weeks, my replacement should finally be here tomorrow. If this one doesn't work I will never buy gigabyte again. I think there is a large volume of these MB GIGABYTE GA-MA78GM-S2H 780G RT out there that are defective from what I have been reading.
