Heyim building a new system and i have these components

 

 

-XFX nForce 680i LT SLI Socket 775 Motherboard OEM

-XFX PVT98WYDFH GeForce 9800 GTX+ 512MB

-Kingston Valueram 2gb (2 x 1gb)

-Western Digital Caviar Black WD5001AALS 500GB 7200 RPM SATA 3.0Gb/s Hard Drive

-Intel Core 2 Quad Q6700 2.66Ghz Socket 775 CPU

- Corsair Vx550w PSU

-Antec 300 Mid tower w/ 2 fans

 

Will the Corsair VX550w power supply hold up? mainly regarding my graphics card. or will i run into trouble? and what problems might i encounter if any?

My only question is that the PSU analysis only took into consideration my processor, the graphics card and the number of hardrives in my system. cant there be more variables that may cause a psu of 550w to not work? or do you think it will be alright? The analysis said that also a 450w corsair would work, but im having a tough time believing that :sigh!:

I would suspect that our VX450 would work fine with the system as well, although the 550 would probably be a better option if you want to leave some room for future expansion, and a little extra headroom wouldn't hurt. If I had to give a rough estimate of your systems power usage it would be something like:

 

680i - 100w

9800 GTX+ - 140w

2GB Ram - 25w

HDD - 20w

Q6700 - 120w

2 case fans - 10-15w

 

This would put you at about 400 watts, but these values would be at 100% load and you probably will not be maxing out every component at the same time during regular use. I would suspect that the system will only pull 200-300w during regular use.
