It seems like my Antec True 430 just cant handle my new system! I dont know why, but I guess my 6800 GT is draining it. Here are all of the specs...

Cooler Master Aerogate 2 ( hooked up to 4 fans )
AMD Athlon 64 3400 CG @ 2.5ghz ( 1.67v )
DFI Lanparty UT NF3 250Gb ( 1.7v chipset )
1GB ( 2x512 ) OCZ EL 3200 rev 2 @ 250mhz 2.8v
BFG 6800 GT 256MB "OC" @ stock ( OCing crashes )
2x 80GB 7,200 RPM IDE HDD's
2x Optical drives

Everytime i overclock my 6800 GT, I get constant crashes in CSS, what do you guys think it is?
 
How many devices to you have plugged up on each cable strand? I dont think you've got enough hardware there to think about overloading a 430w Antec. Most crashes come from people not knowing any better and plugging several components onto one cable strand that draw alot of power and then overload that strand. Dont daisy-chain ANYTHING unless its something that draws very little power like a case fan.

I have everything hooked up correctly. One chain is hooked up to my HDD's, the other is hooked up to my CD drives/ aerogate 2, and the other one is hooked up to the vid card.
 
How do you avoid Daisy Chaining? I have an Antec SL400, and I believe it only has 3 chains coming out... I have one running 2 optical drives and 2 hard drives, one running 2 hard drives and 4 80mm fans, and one running the 6800GT. It seems to be running very well, but I haven't had a lot of time to test it yet (just got the video card yesterday). There was a little bit of rendering messiness in the cut scenes of Doom III, but it played great, as far as I could tell, so I think everything is fine...

EDIT: According to the one power supply calculator, I should probably have about 21A on the 12V line, but my power supply has about 18A. However, it is running okay. I will have to add Power Supply to my wish list for future upgrades, along with the roomy Lian-Li PC65.
 
After running 3DMark05... things got kind of slow... just slow video... now I'm wondering if maybe I need that extra power. Argh... too much money for stuff! There's little excitement in upgrading the Power Supply...
