Can I get by with a 500w PSU to run a GTX 760?

The PSU is an Antec Earthwatt with a Combined 12v rail of 44A.

I guarantee it doesn't have 44A@12V if it's a 500W unit. If you see 12V1 has 22A and 12V2 also has 22A, you can't add them up for a total of 44A. There should be a mention of what the actual capacity of the 12V source in the PSU is, like it would say Total 12V1+12V2 = ... something (if I remember correctly, it's 444W on your unit if you have the later version of it).
Anyway, yes, your PSU is fine.

Oh, I thought that's how you measured the 12v rails.

This is the PSU. How do I find out what the 12v capacity is?

It doesn't look like that information is on the website so you have to look at the sticker on the side of the actual PSU.
If you have the older EA-500 with the gray -- not green -- casing, then it supplies up to 34A@12V, if I recall correctly.

I think this is the same PSU. States 22 amps on 12v1 and on 12v2, but under 12v1+12v2 on the sticker, it says max is 408w, which is 34 amps, probably 17 per rail.
