hi zac,
i built my first pc when i was 14 (im now 16), i though i knew everything (seriously i thought i did). I had saved up untill i had around £550 to spend on a PC.
So i bought everything that i thought was perfect (which it was far from) all arrived, so excited and i built it. everything went perfectly, installed windows settled down to play some age of empires III (
) then my cheap crappy PSU died (cant remember exactly what make it was, but i had bought it for £50 and it was 850W), turns out it took my CPU and mobo with it. I was gutted. the money i had spent the best part of a year savin up for had pretty much burnt in front of my eyes.
So i started saving up again, and this time i came here, the amount of advice i got was amazing (along with the criticism). anyways enough of my story
was just trying to get my point across about how good research is before you buy. (EDIT: sorry if that sounded a bit patronising it wasnt meant to)
Basically im trying to say that we live an learn, especially about PSU's, again, as everyone else has said, using that PSU may kill your whole PC, but if you want to take that chance then its up to you.
In regards to the rest of your build, i admire you for what you have managed to pull together, yes it may be a 'strange' gaming build, but as you say your not doing much serious gaming so it should be fine
and yes the 8 cores will definately help with photoshop and the fact you got them for that price is even better.
i would think that 10gb RAM would be over kill, but depending on how you develop your experience with PC's (if you decide to play around with VM's for example) then the extra RAM will be of great use......so if you can get it cheap and you can afford it then there will be no harm in buying it
I think everyone else on here got a little edgy because of the fact it was such an unorthodox pc for gaming and then the PSU just set the alarm bells ringing
also i would stay on this forum, the amount of help and advice i have got from here is huge, and (most of the time
) it is always friendly
good luck with your PC and i hope it doesnt decide to blow up on you
