Hello again, everyone!

Just got my hands on my new rig, got it all set up and running great, and now my next step is to look for a PSU that will fit my needs once Im done with the last of my upgrades.

My build looks like:
Antec 900 Steel ATX Case

MSI P45 Platinum LGA775 Motherboard
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Intel Core2Duo E8400 Wolfdale 3.0Ghz
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

XFX GeForce 9800GT
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

4Gb (2x2Gb) G.Skill 1066Mhz Memory

Western Digital Caviar 500Gb HDD

Creative Sound Blaster X-Fi Xtreme Gamer Sound Card

Only issue is, my PSU is a 550W Corsair, and Im looking to bump up to an ATI 4870 in the near future, and I know that PSU wont cut it.

Therefore, Im looking for a MODULAR power supply that will be able to handle this proposed rig without any problems.

Any suggestions?

The Corsair 550 can "cut it" with a 4870, no problem.

+1 for what DellUser1 said.

A single 4870x2 video card uses 270 watts and 23 amps at full load.

The Corsair 550 12 volt rail is rated at 41 amps.

The rest of your components will not use very much power.

One of the problems we have here is that posters asking about power requirements have a tendency to overestimate their actual needs. It happens all the time here. In your case you already have a high quality psu that is very stable and reliable. Corsair is one of just a small handful of psu's that are recommended by the veteran posters at this forum.

If you still want to change over to a modular PSU, Corsair HX520 or Seasonic M12II 500 would be very good choices.

Thanks for the responses guys!

I guess the voltage and amp rating works from what yall have said, but my only other reasoning behind moving to a modular is so that I can take out all the crap taking up space in my rig that I dont need at the moment...

Either way, a single rail with a high volt and amp rating is ideal, Im guessing?

Correct. Actually, a lot of the psu that are advertised as having multiple rails only have one rail. Those multiple rails are usually "virtual rails". It's an advertising gimmick.

The number of rails generally makes no difference.
