Get a CX 450 Gray label if possible in the least. Rx580 is very power hungry. Cheap units might not keep up with it.

It's not complete trash but it's not exactly great either.

What's more worrying is that its a model that harks back from 2010.

How long have you owned it from new?

Really it needs replacing if you're going to be entirely sensible.

The 580 can spike to 200w at points, it needs a rock solid quality 500w plus pllsu to run safely imo.

The cx 450 will handle it but it wouldn't be first choice, it's a little too close to its limits imo.

I was also thinking the same thing. But looks like CX 550 is a bit more expensive compared to what he is probably ready to spend. (I even edited the PSU in my post. Originally suggested the CX550.)

this is what i always scared of, the 2010 product, i buy this psu 2nd hand and dunno how long the past owner using for

so i should turn off my rig and find a proper psu ? a 80+bronze 500w should be fine right ?

First of all, NEVER by second hand PSUs. The older it is, the earlier it'll fail.
No need to turn it off. Just don't play games until you get a new PSU.
80+ certification doesn't matter. The quality matters. And for a card that power hungry, Corsair CX550 is the cheapest safe bet. Spending on a PSU is worth it.
Get something from tier B or above as per this thread.
