PSU only consumes as much power as it's required by the PC. Of course, you need to take into account the PSU efficiency if you want to know how much power the PSU itself consumes.
Your Corsair VS650 PSU is only 80+ certified with 82% efficiency.
With 82% efficiency and 500W load on PSU, the PSU itself consumes 609W. 500W is delivered to the PC while the rest, 109W is wasted as heat due to the PSU's 82% efficiency.
Formula to get the total power consumption would be: system usage divided by PSU efficiency (500 / 82 = 6.09), and then multiply it with 100 to get the total power consumption of PSU (6.09 * 100 = 609W).
For comparison, i'll take my Seasonic PRIME 650 PSU that is powering my Skylake build (full specs in my sig). Since my PSU is 80+ Titanium certified with the efficiency of 94% and if my system were to consume 500W then my PSU would consume total of 532W. Due to the excellent efficiency of my PSU, only 32W would be wasted as heat if my PSU has to output 500W for my PC.
I used the same formula to get my PSU total power consumption if the load on PSU were 500W: system usage divided by PSU efficiency (500 / 94 = 5.319), and then multiply it with 100 to get the total power consumption of PSU (5.319 * 100 = 531.9W ~ 532W).
Here's also PSU Tier list: http://www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html
Since Corsair VS series is low quality (Tier four) PSU, i suggest you replace your PSU with Tier two or Tier one unit.
Anything from Seasonic will do, e.g S12II-620 (80+ Bronze certified, Tier two, with 85% efficiency) or G-650 (80+ Gold certified, Tier two, with 89% efficiency). I also included my PRIME 650 (80+ Titanium certified, Tier one, with 94% efficiency),
