I am building a rig and have the seasonic s12III 500 watt 80+ bronze as my psu and I was wondering if this is a good psu. My psu budget is around $40.

It's not great, but nothing under $40 is. Main thing the s12iii has going for it is how cheap it is. After sales and rebates I've seen it as low as USD$22. Not sure if those are still available.

 

What system are you building? Depending on what your system is it might be acceptable, or you might want to consider something else.

Maybe you could drop to a 2600, 590 --> gtx 1660 and afford something like the cx450? Depends where you are located though

I've been running the 450W S12iii in my HTPC for 18 months.  PC is on 24/7 and I've encountered no issues.  PC is not very power hungry and only is used for watching/recording TV and streaming Netflix, ESPN+ and Amazon Prime.

Interesting, because the S12 III only came out earlier this year. The predecessor, the S12 II was among the worst PSUs you could buy for the price 18 months ago, though.

Why the RX 590? it's only a factory overclocked RX 580.

 

I'd go for the RX 580 if that money saved allows you to afford a real power supply like the latest CX's

I guess mine must be the S12 ii then.  It doesn't matter much as it's only driving a Pentium CPU and with Intel graphics, an OS SSD and a 1TB HDD for storage.

The 590 is actually the same price right now maybe actually cheaper
