I have a PSU that has 22A on the +12v rail, i need to use a GFX card that says minimum 26A on +12v rail. Will I be ok with this PSU or do i NEED to upgrade?
Thanks

Is this a single rail power supply or a multirail power supply.
If it's a dual/quad rai lPSU and you have 22A on an empty rail you should have enough power (264W worth)
What card are you getting?
If it's a single rail PSU you will not have enough power for sure because of other components.
Could I use a PSU with only 16A, but 2 +12v rails (16A per rail)?
I have a 9800GTX+, it needs 2 pci-e power cables.
I had to look that card as it's not recent
If you PSU has two 16A rails you should be fine as a full system with this card apparently draws only 264W of power (22A worth) that is if you only put the graphics card on a 16A rail that's the only thing that can be on that rail
I woulld suggest using a PSU with a single 26+ amp rail so you can have headroom. Headroom not just for future plans but safety
I would steer clear of so called 'dual rail' PSUs, at the very least make sure it is 80+ certified, that gives you at least some level of certainty about its quality. Alot of cheap PSUs used to be very dubious (not providing stated ameperages, just stating peak draw, stating draw from each 'rail' then adding it together even if it cant draw that, etc..etc..) in terms of quality, so you often hear some vendors overstate power requirements to be on the safe side.
Another reason for this is PSUs loose their capacity over time, obviously some PSUs are better than others and some worse, i.e. the more expensive corsair ones with 8 year warranties made by a repoutable company like seasonic. All in all I would stay clear of multiple 'rail' PSUs, you have too do fancy load balancing nonsense, and its just not worth it.
Also something interesting that you should know, many of the PSU vendors are just reselling other companies power supplies branded as their own, such as I believe antec, corsair etc..etc.. at least for some of their models.

your not one of those single rail is better because single rail is better people are you? There is almost no real evidence that multi-rail psu are inferior to single rail
