Build help, need a power source and general advice on $1000-$1100 gaming machine

Background, I'm from Canada and this is my first build, but I helped my sister build one and have been looking into parts for a while. I was planning on it being less than $1000 but it looks like it may be more unless I wait for sales or a super good deal.

So I've been watching tek syndicate for a while and I figured I'd loosely follow their AMD FX 8350 build. I also like the ASUS TUF series with 5 year warrenty so I went for that motherboard. Other than that, I'd like to add another video card in a year or two, so that puts my total power up to 629W.
I'm not familiar with power supplies, so would a 650W supply be enough? Or should I round up to 750W? I think I can reasonably afford a $70ish power supply, although I can go higher if there's a good argument.

I'm also flexible on the graphics card; I just chose this one since someone on reddit (see specific comment here) recommended it for its good price to performance ratio. I'll grab an aftermarket cpu cooler, haven't decided what yet, but likely something $50, and a couple extra fans later. This will likely push my build to $1100 for just the tower, but that's alright.

Extra info: I don't need peripherals (yet), no water cooling, I will be OCing (but I am planning on not overly stressing the system), will likely get an OS through work or school for little to no cost. Gaming: I like FPS over 40 and closer to 60 is ideal, resolution at 1080p, maybe 1440p if I feel courageous.

Any advice and/or suggestions are welcome!

I will try to help out as much as i can here, and offer accurate statments. I have never built a comp (yet) but i might be able to help so here goes.

 

You said you were getting the tuff series, and that is all good and dandy, but are you getting and intel or AMD board?

 

Here are some things to think about

 

1) Anything over a quad core is Over kill for gaming. Gaming hasn't evolved enough to use more than 4 cores.

 

2) Quality PSU. Look for a power supply with a single 12 volt rail and rated atleast 80+ Bronze ( gold silver and platnium are better obviously but bronze at least) If your Power supply goes, your whole system is in jepordy. 

 

3) Motherboard structure. Case Structure. You said you might get an after market cooler. Awesome, but be aware about the space around the CPU and the case. Some cases mount the board pretty high, and make closed loop water cooling a pain or not even possible.

Last is an SSD. (Solid state drive) Optional of course, but it reads/writes fast so when you play the game will load up faster.

 

Hope i helped!

You don't need 630W for that rig. That is a gross overestimate. Even with a power hungry card, all modern single GPUs will only use about 200 to 250W max on their own. If you want to build a very efficient system, get a PSU about 20% larger than what you need, and keep that efficiency at 80+ Bronze or above. PSUs are rated to be a certaine efficiency at all load levels. 80+ Bronze is 80+ Bronze, or at least supposed to be, at all loads, from 20% to 100%. However, if you are using a 1600W PSU on a system that uses 200W, then your efficiency will probably be lower than 80+ Bronze, depending on your PSU, because, A.), 1600W at 200W load is at 12.5% load, which is really, really low, and will probably put you in 80+ or below range. 

Ripple is alos an important factor. If you don't know, ripple is the micro-fluctuation of the voltage on the 12, 5, and 3.3V rails, which, even within ATX spec, at the high-end, can fry your components. If you have a 100mV ripple, which is HUGE, then thousands of times a second, you could be sending up to .1V extra to something like your GPU, which may be the most expensive part of the rig, and usually operate below 1.1 to 1.2V. If you are already pushing it really far, with a heavy OC, at 1.25V, then another .1V may fry it, and ruin your purchase. Keep the ripple below 60mV, preferably below 40mV, if you can. At $70, there are plenty of choices with a ripple well within Brennan-approved ATX spec.

In all reality, I am probably getting picky, but you could look at other characteristics of teh PSU, as well, such as load line regulation, namely, the quality of the soldering, the application of the heatshrink, and overall assembly, but we'll just gloss over those for now. 

Now, at $70, there are plenty of great choices. First thing, forget about brands. Brands are there to put stickers on things and offer warranties for a lot of money. Look at the OEM. A few companies, like Seasonic and Enermax (some of the best PSU manufactueres for high-end PSUs, as a generalization), are their own OEMs, so they make their own PSUs in-house. However, Corsair, Anteq, OCZ, and essentially everyone else uses other peoples' OEMs, some Seasonic, CWT, in Lepa's case, Enermax, and many, many others that I won't bore you with.

So, since your system, or rather, your sister's system, won't use more than 350W, pretty much ever, you could get a 360W PSU, and be fine, but seeing as the only good PSU at that wattage with a standard ATX mounting scheme is the Seasonic G 360, you may want to look elsewhere. You get options around the 450 to 550W range, which are well within a $70 range, really such as the Rosewill Capstone 450, and 550, plus 450M, and 550M (same unit, just semi-modular), Seasonic G 360, 450, and 550 (80+ Gold, semi-modular), Rosewill Hive 450 and 550, XFX Core 450 and 550, and the Lepa G 650, which is overkill, but has great features for the price, and usually drops to around $70/80 on sale, pretty often, actually.

Fantastic comment brennanriddell! So since I'm planning to add an extra GPU in a year or two to crossfire it, I'll just add a little to your estimate. 

And at Tr1ckst3r, if you click this link, then you'll see I'm going for an AMD 8350 with an SSD, but thanks for those suggestions and i'll pass on water cooling and just use a fan. i'm not concerned with room in the mid-size tower.

Get a 650W for Crossfire :)
