Ok so i have this gigabyte odin silent 585w. On the website, it says it comes with an 8 pin pci express connector, and it also says so in the manual. Now that im getting a 9800gx2, i looked and i cant see an 8 pin connector. Can i send the power supply back because of this, bearing in mind i have had it for 5 months or so? The warranty is 1 year.
