An acquaintance is willing to sell me a corsair CX 500 bronze for 20$, basically unused.
I need a new power supply and I was looking at the EVGA 500W standard for 40$.
Which one should I go with?

Depends on what you are going to be using it for. Neither PSU is exactly good. Personally, I would spend a bit more and get a proper PSU. Either of these are far better, and not overly expensive. http://pcpartpicker.com/parts/compare/seasonic-power-supply-s12ii520bronze%2Cxfx-power-supply-p1550sxxb9/

To be honest, neither of those PSUs are particularly good.
Unfortunately Xuebao61 is incorrect. That is not a good deal. http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html

It depends what you need it for though. An office/basic setup, I would go with the EVGA, being better than the CX (not great, but good enough for an office/basic desktop).

If you're putting it in a gaming rig - essentially any GPU made in the last couple of years, or OCing, I would avoid both.

For slightly more than the EVGA, either of these would give you peace of mind:

520W is such an odd wattage to have. Usually PSUs sit on the 50 or 100 marks these days. I mean, I know there's lower wattage ones that are like, 430W, but it's still odd to see one that isn't rounded.

SeaSonic are truthful in what they are, and provide a quality unit. I believe they have 620W and other 'odd' numbers.
They make plenty PSUs that are 50W or 100W incriments.

Some lower quality PSU manufacturers (or "branders") outright lie about the max output or capabilities of their PSUs, rounding them up to a 50 or 100W incriment. (and sometimes, I believe, just pull a number out of their....). That really distorts the market "standard" of 50 or 100's.

IMHO, if every PSU was rated accurately, the market would be full of random numbers. 17's, 4's etc. Then you could spot the truly quality units a mile away.
