Question RX580 with older PSU for short term non-gaming, okay to use?

I've got a new Corsair CX650-F on the way but my RX580 will arrive sooner. I'd like to use it to run some final diagnostics on my new 4K monitor. I won't be gaming on it.
Current PSU is an old Antec Earthworks 430W. Obviously at full load we'd have problems, but for short term non-gaming use, would I run into any issues?

Haha, not until the magic smoke comes out and you need to figure out how much stuff also died :p

Other than that, does that PSU have more than one six pin GPU power connector? I don't think the card is going to operate well (maybe not at all) at less than connection, I'd guess it takes a 8 pin and a 6 pin.

It definitely takes both and would need an 8 to 6 adaptor to use two 6 pins for power. The original packaging came with one, if it doesn't come in the box (this was open box) the this is a moot point anyway as the old PSU doesn't have an 8 pin GPU connector.

I guess I can do some googling later. I suppose I'm looking for idle power draw and a way to artificially limit the power draw (aside from my PSU doing the limiting by crapping out!). I just really want to run the monitor through it's 4K paces before the return window is over. Waiting for the new PSU just kicks the can further down the road.

I ran an RX480 with an 4690K at 4.5GHz on an Antec Neo-Eco 520C PSU for over 4 years, never had an issue. Before the RX 480 it had a 7950 (heavily OC'ed) for about 3 years. For regular usage you will definitely be fine, but even if you do game, you may still find out you are ok. Oh, and before the Intel CPU, I actually ran the 7950 for a little while with a 430W PSU and a Phenom II.

I should have clarified earlier, currently running an Intel 3750K on Z77 chipset, no OC as I think the chip would do it but the PSU and chipset have other ideas.
I'm building a new setup and the RX580 gets me through however long it takes for supply/pricing to return to normalish levels. The current setup becomes the wifey's. I probably need to look into fully replacing the earthworks as its now 7 years old but PSU prices are just so expensive when you try not to buy junk.
