GPU:
Sapphire Radeon RX 550 PULSE 4GB GDDR5 128-bit

HDD Seagate BarraCuda, 2TB, 7200rpm, 256MB cache, SATA-III
Motherboard: B75M-D3H rev 1.1
CPU:Intel I5-3470 3.20Ghz
Psu:I have a Spire Black Eagle PSU that's at least 450W,I can not tell for sure since it literally doesn't say anywhere unless I remove the psu from the computer.But just to be sure,will 450W be enough?

Just to clarify, you did not post the GPU in question anywhere.
Secondly, hopefully it is not a reasonable power GPU as whilst i'm sure it'll be compatible, that PSU is likely awful quality and is not well paired with almost all dedicated GPUs.

How long have you had the PSU?

It will work, as I believe the 550 is powered through the PCIE slot only. But it still doesn't detract from the fact its a poor quality PSU that if it does go bad, could easily cause damage.
