PSU suggestions

I'm planning on upgrading my computer. I already know everything I'm getting, but I'm not sure what wattage would be a nice sweet spot with enough to upgrade.

I'm planning on switching out my fans for non-led, getting a fan controller, and the NZXT RGB Hue. I was also going to get a new graphics card and possibly SLI (which I haven't decided on just yet).

At the moment I have a 630W. I may even get an i7 a little down the road.

Just curious if I should go with around 800-850 or if lower would work as well.

Price is kind of big for me since I can't afford a super expensive power supply.

I would stick with what you have and save till you can pop for a premium properly sized modular or semi modular PSU. Brands I like are Corsair, Seasonic, Thermaltake, Antec, Coolermaster. I would highly consider a 800-1000 watt depending on affordability and just remember the system draws only what it needs but it's the reserve of clean power that keeps the rig alive and even running cooler and quiet. If you see yourself using top flight components, SLI'g or Crossfiring or Overclocking then the extra capacity is well worth the added cost and remember that each year the PSU will lose roughly 2-5% output and this I think is where people can spec their PSU to close to actual need and have issues later. Also get a high efficiency unit in a Silver, Gold or Platinum rating.

There is an 850 I can afford right now. It's an XFX and I heard they are built by Seasonic. It's 80 Plus Gold and also modular.

I would say 850 will be more than enough even if you plan to SLI, I run everything in my system specs on my Antec 750, I would have needed more if I was to SLI the card in my system specs but that was a pretty high end card. I sold it recently and will be replacing with a new gen card soon.

I'm very impressed with my XFX graphics card and from the looks of things the XFX line of PSU's are real nice. Maybe post a link to the PSU in question and we'll have a look.

It's on both Newegg and Tiger Direct. I'll probably get it from Tiger Direct to save 4 dollars, but I'll give you the Newegg link.

I fitted one of these to my Father in laws rig a year or so back, it has been rock solid and looks real nice too.

That looks nice.

Yep XFX is a quality brand and you can also look at the new EVGA line of PSU's. Still I love Seasonic:

Those are a bit out of my range though.
