I have an EVGA 400w PSU that I bought the same day as my prebuilt ASUS M32 desktop (i5-6400, 8gb ddr3, etc) and My ZOTAC GTX 950 2gb back in november.

Everything has worked fine up until the last few weeks. Now when I start playing a game, my pc will shut off and reboot. I was told by people on reddit that my psu was probably failing so I sent evga customer support a ticket and they told me to try a "psu paperclip test" which my psu passed because it still works to a degree.

I tried running furmark and my pc shuts off every time i start it. right now i can only run my graphics card at 60% power, and even then it has shut off when playing gta v. I don't know what to do? The psu passed the test so I would assume the customer support would tell me it's fine and not give me an rma?

Well, that is one way to say it...another is to mention that 400w is not a very strong psu for your needs and that unfortunately your psu is not one of the best available. It only has a 2 year warranty and is not even rated for efficiency. Here is a link to their site for the specs of the unit I believe you have: http://www.evga.com/Products/Product.aspx?pn=100-N1-0400-L1

I would recommend that you look to having your psu tested by someone who knows how before you make a decision as to whether it is functioning properly or not. It may be fine, but your system may be requiring more than it can give reliably for your demand upon it. You may simply need to get a better quality, more capable psu.

A paperclip test means nothing but the PSU turns on!!! We already were aware of that since the PC starts. Bad PSU or unstable voltage under load.
Either RMA /warranty or write it off as a learning experience and buy a good power supply not a cheap crappy one.

Here is a link from this forum that has psus grouped by quality or 'tier': http://www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html. I would recommend something from the top two tiers to ensure reliable power.

I advise getting your psu tested, for if it is working properly then you may have a different issue occurring instead. Another thing I would try is to maybe borrow a psu from a friend and see if you are having the same issue (make sure it is a psu of good quality with at least 500w capability), for that can also tell you if the psu is actually the problem or if it is another component in your system.

Hope this helps!
