How Much power and going modular help

[JGBR]

Currently have an old Non Modular 800 W Seasonic PSU

Due to graphics cards issue, going to to change it to modular.

What modular and level of power do you think i need to run the below???
(Considering a 280gtx has a weird 6+8)

i7 920 OC to 4GHZ
6GB RAM
SDD+2 7200 RPM DRIVES
280GTX
P6T DELUXE
5 USB DEVICES
2DVD RW's

PS: is their any modular PSU that i can go straight from 6pin to 6pin and 8pin to 8pin???

BFG cards come with a 6-8 pin converter, and you can buy then if you look around.

Your PSU is decent, I would look at a cable conversion rather than buying a new PSU.

I would look to get an adaptor cable first and see if you could run the GTX280 off your existing PSU.

A decent 800W PSU will run an overclocked Core i7 920 and a pair of HD5970 graphics cards:

I would suggest the Antec Signature 650W:

It is made by Delta Electronics and has very good reviews:
