My under £400 gaming PC opinions?

[SnakeShit]

Hi guys. New to this forum, I was hoping to get some opinions on my first PC build.
This is what I've gone with.

CPU - Intel i5 4690K (stock clock)
GPU - PowerColor PCS+ HD7870 Myst. Edition 2GB GDDR5
RAM - Kingston HyperX Blu 16Gb DDR3 (8Gbx2)
PSU - EVGA Supernova NEX650Gold
Motherboard - MSI Z97 Gaming 3
HDD - Still using a old crappy hard drive that is unknown to me, but I plan on getting a
WB Blue 1Tb when I get more funds.

Thanks for looking!

Seems good , HD7870 is still powerfull till you get more money you can upgrade it,CPU is GOOD overclockable,yea pretty nice start.If you are willing to overclock just buy an hyper evo 212 around 13 pounds.Solid system.

If that is not a G2 or GS then I would replace it with a tier 1 or tier 2 unit. http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html

That particular HD 7870 is tahiti based, and still a decent card, I would probably put its performance close to that of a GTX 950, as it is just below that of an HD 7950/R9 280.

I always forgot about PSU's...
