If a low quality PSU dies it will fry the whole system. Not all Corsair PSU are the same some are good quality and some are bad.
here you can check which PSU are good quality - http://www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html
That is true to some extent but recently have read about seasonic PSU burned out within a month and burning sata connectors , so i dont know if any bronze series are reliable anymore. Corsair ones do heat more under load and might give up soon but its chances of frying the motherboard is very low too . Selling cheap crap wont make you popular like corsair. Else zebronics will be on top. So its not really that bad and way better than any cheap tier PSU.
But then the motherboard needs a quality upgrade too . So at the end, budget is a deciding factor.

I think EVGA lies somewhere between seasonic and corsair . At the end i would go with a PSU brand which has the best RMA support in your area. That will help a lot when you are dealing with over 10 PSUs in a year .
Also there a lot of variations in your build which can affect upgradability. Know your customer if he wants performance or upgradability and How much comfortable he is with overclocking and AMD. Else just get a i3 4130 with h81 based board .
For best upgradability , use 1 8gb stick ram only and this motherboard http://www.expertreviews.co.uk/pcs/motherboards/1402723/asrock-fm2a88x-pro3-review.
Do understand the fact that if someone without proper knowledge of overclocking does it and fry something , he will contact you, and you wont be able to do anything since the oc voids warranty and you will gain bad rep . So give AMD build only to people with some basic level of knowledge about computers. For the Dumb people , Intel build will give you and him much peace of mind.
