Hi --

I haven't really kept up w/ the latest and greatest in hardware for a while (since 2007 pretty much), but I'm thinking about making the following changes to my setup:

E6300 @ Stock speeds (was stable at 2.8ish for a while) --> i7-920
Gigabyte GA-965P-DS3 (rev. 1.0) --> MSI X58M
2x1 GB DDR2-800 --> 3x2 GB DDR3-1333
2x250 GB SATA --> +1.5 TB SATA drive (for 3 hdds total in the new setup)

I'm keeping the following:
Geforce 8600GT w/ 2xDVI-connected 1920x1200 24" displays
1xAsus Xonar DX
1x500GB USB 2 external HDD
2xoptical drives (hardly ever use these)

And will change my OS from 32-bit Linux to 64-bit Linux.

I currently run the E6300 setup on a Sunbeam SUNNO550-US PSU, which has the following specs (http://www.newegg.com/product/product.aspx?Item=N82E16817709004):

Will this be sufficient to power my new setup? I know it's not as beefy as what people recommend these days for i7 setups but seems almost as good as some "i7-certified" PSUs I've checked out that are also 550W. I use this rig mainly for software development/work and multimedia (watching AVIs and stuff) -- no gaming at all. I have no plans to add extra video cards or anything at this point (and if I ever did it would probably be to just run bigger monitors or something).

If it's not sufficient, may as well ask in this thread -- any recommendations for what I should get?

Thanks for any help.
 
I wouldn't use it. A good 550W PSU would be plenty for an i7 system with a single video card, but your PSU is an older model without any PFC, mediocre efficiency, and unimpressive performance overall. I wouldn't risk using it in a modern system.

If you want recommendations, post a budget. A good option would be the Antec Truepower New 550W that Newegg has on sale for $80 though: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371020

There's also the 750W version for $20 more if you want some extra headroom: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371025
 
Ok, thanks for the replies. I think I may as well just get the 750W one and make sure it lasts at least a couple more upgrade cycles. Thanks.
