It will be a sticker like this on the PSU, if you can find out I could be more certain
I'd imagine it'll be fine as long as you've a 6pin PCIe to connect it, Dell PSUs are solid enough and the 5770 didn't use all that much juice. It's borderline but should just about cut it OK with a bit of headroom.
If you did upgrade your PSU though it's the sort of thing where if you buy a good one it'll carry through into future builds.

That's what I'm thinking. Get a gaming case with a 700W> PSU and then I can add extras when I can.
