I am replacing my dead video card with a GeForce 9800GTX+ and have a Q6600 quad processor. According to XFX, I need to upgrade my 400w PSU to at least 630w. I need recommendations for a good power supply. I suspect my old power supply may have caused my dead video card. Thanks for any help you can offer.

U should be fine with a 550. (but overkill never kills anyone ;) )

Mainly stick with Corsair, Seasonic, Antec (they have some good ones...especially the new ones) and PC P&C is always good

Also, decide if u want modular or not (can change price a bit)

um, sorry - suchanewb is a pretty good description of me. How do I know if I want modular? Is it size? Fit in the case?

Here ya go.

Newegg is pretty good eRetailer

When looking for a good psu, make sure there is at least 18a+ on the 12v rail.
(you will need more depending on setup)
I recommend a single 12v rail over multiple. (multiples cost a little less but may not adequately power your system)

Try to get a unit with Active PFC which will compensate for loss of power.

Brands: PC Power & Cooling, Corsair, Silverstone. Antec and Thermaltake can be considered as well but I would go with the first three by default.

Thanks much for the help. After careful consideration...I'm thinking one of these two:

PC Power & Cooling Silencer PPCS750QBL 750W ATX12V / EPS12V SLI NVIDIA SLI Certified (Dual 8800 GTX and below) CrossFire Ready 80 PLUS Certified Active PFC Power Supply

Corsair TX CMPSU-750TX ATX12V & EPS12V Power Supply

Any warnings, opinions, facts I should know?
Thanks again.

One last question...should I go with the Corsair 620 HX instead (of the 750 TX) to get a modular unit? It has triple rails instead of single. Being a newb, will it be easier to install?

Interestingly...Corsair says I only need like a 540w but for a few bucks more, why not overkill a little. :)

Multiple or single rail really makes 0 difference. Generally a multiple rail is just a single split

The only difference is modular or not.
Personally, since u really dont kno the difference, grab the 750
 
Silverion - Yes, that list is not absolute and it is subject to change and personal opinions. On top of that the updated list is from last May. However, what I found interesting was the list of links to other web sites that review and test power supplies:
