Powersupply upgrade help?

[hardpinoy]

it seems my 485w powersupply is showing its age. and i need to upgrade to a higher end powersupplys, heres what ive been looking at:

OCZ 520w powerstream powersupply
OCZ 600w powerstream powersupply
Enermax 600w Noisetaker powersupply
Seasonic S12-600 600W powersupply
Antec TruePower 2.0 550W ESP12V powersupply

heres my system:

1x AMD64 x2 3800+
1x Asus A8N-SLI premium
2x Evga 7800gt
2gigs OCZ PC4000 EB platinum edtion
2x 80gig seagate hard drives Sata
1x 250gigs seagate hard drive sata
2x LG dvd burners
1x audigy 2 sound card
4x 80mm fans
2x 120mm fans
1x vapochill phase change cooling unit

i plan to overclock like crazy so i need alot to power my system, especially those two 7800GT's wich will probably hooked up to watercooling in the future. im thinking the OCZ 520w powerstream, because it has a strong single 12v railing. which apparently helps overclock a little. and its not a bad price. what do you guys think?

damn.. I just bought mine yesterday (cause it was the biggest I could find locally, and needed a ps right away) for $152. Oh well.. I hope it's a decent ps since I have had about 3 enermax's before this one.. and none of them ever had any problems.. just the way I like them.

right now i have a 485w noisetaker, and my system is probably just as demanding as you, and i can overclock pretty decent with my system and still have ROCK solid railings all across the board. so im guessing the 600w will be plenty

just curious, if your system is running smoothly then why are you upgrading your power supply? or is the system shaky?

also i am surprised the 485w noisetaker can handle sli
