I have an Athlon system right now and am going to swap the hardware to an Intel Quad Core. In the process, I am wondering if I should upgrade my current PSU which is a tad borderline to a 750w, or save the money? My hardware will be:
And I am thinking about using my 90 day step to move to a GTX 260 GX2 as is rumored to release in January.
Will my Antec NeoPower 550w with 3 12v rails with 18 amps per rail do fine? Or will the Corsair 750w with a single 12v 60amp rail be a lot better?
I can't decide, because I feel like I am borderline right now on the PSU, but yet spending $100 to only get 200 more watts and a total of 6 more amps seems a little unncessary, and I would be tempted to get the HX1000 from Corsair, but that won't fit in my case (Antec P180), and then I'd have to buy another case too...
If you are going to be OCing, you might want more than 550w total since you have a lot of HDs in the system. If you are 100% stock you are OK with the 550w. If you go to the GX2 card, you will definitely want the 750w.
