A Corsair CX 500 Watt 80+ Bronze PSU, non modular. I found it wrapped and brand new in my dad's closet one day and he didn't remember how he got it as he is not into desktop PCs. It probably came bundled with something else he bought. I lightly used it in a spare parts PC to test and play around with different components, but since I'm selling most of the stuff I'm not using I won't be needing it anymore! Has a few scratches but works perfectly fine.
