This is my current PSU's specs (awful):
+5V @ 25A +12 @ 19A +5sb @ 2A
+3.3 @ 18A -12 @ .8A
So I'd like to upgrade, but the problem I'm having is figuring some things out:
1.)Do I need to see all the rails listed above with the same amps or better in the new PSU's specs?
2.)What if the PSU I want to buy is missing the specs for a rail? or in other words, I have to have all the rails listed in my current specs, correct?
3.)Will the new PSU use all the same inputs on my motherboard?
Let's take an example:
XCLIO DIAMONDPOWER 680W
1 x Main connector (20+4Pin)
1 x 12V(4+4Pin)
8 x peripheral
8 x SATA
1 x Floppy
4 x PCI-E
I've hilighted in red what I think is a problem. As far as I know, just having the total wattage exceed your old PSU isn't enough, all the rails need to be the same too (or better) (I think ?)
The current machine I have is from a few Christmases ago; an OEM machine from Circuit City.
The HP Pavilion Elite m9040n.
This is its motherboard:

The mobo only has PCIe x16, so
1.) Is it worth it for me to buy an NVIDIA GTX 260 if I can't utilize all the bandwidth of a 2.0 card?
2.) Would buying a 9800 GTX do the same because of the bandwidth cap?
3.) Would there be a cap, or in other words, does the 260 use all the PCIe x16's bandwidth?
4.) Do I have the correct power connection for such a high end card?
I think a lot of the questions I have can be answered by simply knowing the specs to look for, but I obviously don't know what to look for. Again, I apologize for being so clueless, I've done hours of research spread out over the course of a few weeks and I've figured out a lot, but I'm just not able to find clear answers to these questions anywhere. Any help answering any one of these questions or all of them is greatly appreciated!
