Rx 460 not working in 1155 rig

[Commanderrage77]

So I recently bought a rx460 sapphire nitro graphics card and Its not working in my computer. Fans turn on and lights but the output from the GPu is just black on my monitor and then goes to no signal.
I have tested the card in someone else's PC and it worked fine.

I have...
I7 2600
580w Orion psu
Mini itx lga 1155 gigabyte Mobo
8gbs ddr3 ram

Your power supply is absolutely atrocious. It's listed as Tier 5 which is defined as such: "Avoid IMMEDIATELY. These units are highly unsafe to use. No such protections added, very thin gauge wiring used, false advertising and too much to list. Reference to a higher tiered unit for a better, money saving and a much safer unit. For your safety's sake, please don't order or pick one up for use in your system. These units are a potential fire hazard and could even kill you, let alone your system."

Please replace your power supply immediately. I recommend the Seasonic S12ii 520w Bronze for your rig.

Oh wow I didn't realize it was that bad, I'll make sure to replace it. So would that have stopped my GPU from working?

Would the power supply have stopped my GPU from working?

Yes.

For a general rundown of power supply brands and models, the Tom's Hardware PSU Tier List is a good place to start. Do note that this list does not list comprehensive information on individual units.

Let's use the example of Seasonic M12ii Bronze EVO Edition power supplies (Tier 2) vs Cooler Master V series (Tier 1). The Cooler Master ones have slightly better ripple suppression (voltage is more stable) and they take very kindly to heavy overclocking. The Seasoonic ones are built to a slightly more affordable price but are still well above acceptable quality. What the PSU Tier List doesn't tell you is that the Cooler Master units struggle when put in a top-mounting case where they share warm air with other components. The fans will ramp up excessively (making them loud), and voltage output may become slightly unstable as the internals heat up. The Seasonic units do not have this issue, although they don't like heavy overclocking as well. A boost of 400-500MHz, sure, but more than 500-600MHz and you'll be nearing the limits of the unit.
