Around 650w 700w PSU. Check out the link below. On sale, and its usually $100.

You do NOT need a 650W PSU for this rig.
Some versions of the GTX650 do not need a PCIe power cable; the ones that do barely need it. In any case, the GTX50 is a low-end card. If you have not yet bought it, and this PC is for games, you will want a stronger card. A FX-6300+GTX750Ti or GTX660 would perform better than a FX-8320+GTX650.
Consider future upgrades. If unlikely or limited, a 380W Antec Earthwatts is sufficient for your rig, including any graphics card with no more than a single 6-pin PCIe power cable (e.g. the GTX660). If you do plan more extensive upgrades, and/or plan on high overclocks, get 500W-550W. Make sure it is a quality unit, such as one built by Seasonic (their own, XFX, some Antec), Super Flower (Rosewill Capstone, new Kingwin), Delta (some Antec), or FSP (their own, some Antec).

So people say you do NOT need this and you do NOT need that. Anyone else ever considered being safe? He's using a dang 8-core for christ's sake. OP, if you want to save NOT EVEN TWENTY BUCKS with buying a 500w PSU, go for it. Spend ONLY EIGHTY BUCKS, and you can have more than enough power PLUS SOME if you ever want to upgrade. Value OVER price, always.

yeaah! somebody's talking here. how about a seasonic eco 500?

Being on the safe side? This is like using 1.5k watt psu for a single gtx 780 build. This is way too overkill. It looks like he has a budget, and a low watt psu is generally cheaper. XFX Proseries xxx and core edition, are very bad marketed, but very good in terms of price to performance. Goes from 450w-1250w i think.
I am gonna get one of those psu's.

I've got a FX-8320 with a HD7970 (1000MHz), and it pulls maybe 320W from the wall during light use, and I'd be surprised if it breaks 400W gaming (haven't looked). That same HD7970, overclocked to 1130MHz, running flat out mining BTC last year in a rig with an i5-3570K was pulling 312W from the wall. Safety comes with quality, not [claimed] wattage. I'd take a 380W Antec Earthwatts over a "650W" Diablotek any day, all day.

Well hey man, if you feel comfortable using a PSU under 500w, go for it. I'd take being on the safe side over getting the lowest amount of what I need.

And once again, your 300-400w PSUs are almost as expensive as the one I advised that was over 700w. 80 bucks for a 100$ PSU? Screw getting lower performing PSUs if there's a price like that.

 

[Onus]

Actually, I'm using 650W PSUs in two rigs (to allow for a 2nd graphics card if I ever want it); one is a 6-7 year old Antec Signature and the other is a new Seasonic SSRM. I frequently use the EA-380D in budget builds I do for others though, and none have ever croaked. The rig that I had mining until last summer was using a 550W Antec Truepower New.
Who builds that Thermaltake? The brand is hit or miss, but that's a good deal if the quality is good.

The OP doesn't live in the U.S.A. so your price quotations are meaningless. You also haven't determined whether or not the brand and model you've recommended is even available where the OP lives.

Where i live, i can save about 25%-40% by picking a 200-300w lower psu. That goes for pretty much everything. That would be a good boost to the gpu.

It depends on what you want. If you feel comfortable at 400w, go for it. If you are only comfortable with 650w+, go for that.

I think its stupid to pick an overkill psu. It even makes the power more ineffecient. - more heat and noise. But some prefer the higher watt to be future proof for sli and such. It all comes down to what you want. Again, pick what you think is enough for you.

It also depends on future expansion. "Gypsy" (described in my .sig) which has a similar-powered graphics card, but a less demanding CPU, only pulls ~117W from its UPS during things like browsing, and ~126W while playing Guild Wars. Even allowing another 50W for his CPU, he could "get away with" a <300W PSU. That's not what I'm recommending, but 750W is way more than needed, unless future plans include one or more extremely powerful graphics cards.

 

[FunkyFeatures]

I for example, plan on doing sli down the road with high end cards. That could maybe pull 600w, and to be safe i might go with 750w.
All about them upgrades
