Could a 500w PSU support a midrange PC?
My friends are trying to convince me that I need 700+ but I don't see why.
With a single GPU, sure.
Absolutely. Needing anything higher is SLI/Crossfire meme tier.

You using overclock or AMD?
You might need it
It's good if you want to upgrade later. I bought an 850w psu and now I'm fucked for SLI.
Yup, but get the XFX 550W.

Depends entirely on your build. If you're using an R9 390 or something even more power-hungry it might be a good idea to stick to 600W.

1kw will out put 500-600 watts in 5years

This computer was running on a 400W HEC 80+ PSU, recently upgraded to CX600M
Think I could SLI a 760 with a 550w supply? 760's are dirt cheap on Amazon right now.
>tfw been using a budget alternative-brand PSU for 3 years now with overclocked amd rig

I've got an old video card and a high end CPU. I think I'll be fine with my PSU since I'm trying to budget and I'm salvaging my old PSU.

Lol, kid you've been on /g/ too much.
If you used a 2011 extreme intel cpu and a 390 you MIGHT hit 475w, and that's over estimating.

Using an OC'd 4690K with an OC'd R9 290 Vapor-X on an 80+ PSU, actually. Pulling just over 500W from the wall under 100% load on both.
What happens if your PSU doesn't have the power draw needed by the parts?
Do they just not max out on performance or does the computer crash?

Depends on the quality of the PSU.
Good PSUs will shut off to prevent damage, but bad ones can literally go up in flames or fry your components.

Im running an i5 4590 and a 390 on the xfx 550w
>>51604866
OPs post isn't talking about OCing. You could OC an e8600 with a 9800gtx and get to 500w. EVEN still, a 650 is more than overkill for a non oc 390
>>51605081
Yeah, about 500+W is fine, but I like to have a little safety margin, you know? Overclocking headroom and such.

I'd like source on this. Not because I don't believe you (ok, I kind of don't believe you) but because I'd like a better understanding of how a PSU actually works and what the wattage rating means in terms of the physical components.

jonnyguru.com has some nice articles and really good PSU reviews. Go look at some reviews of cheap shit, they literally blow up under load.

the fuck? I'm on an OCed 3570k with two 7950s @ 1100 core and 1575 mem and 850W is plenty.

With my 4790k and 980 ti under a full system load, (1 SSD and 2 HD) i pull 400-450 watts.
They say you want to have a buffer between your max and what you are pulling max. You'll probably pull less, but will be much closer to your limit, while I have a 650. I'd go 650 at least. Won't take up much more room or cost much more.
