New build choices!

Corsair TX650W V2 is available here. Should I get it instead of the Seasonic 520W?

For a GTX 580, I'd prefer the TX650, yes. Seasonic 520W would handle a stock 580 fine but TX650 has more room for overclocking and such without having to worry about stressing the PSU too much.

However I have heard of some complaints of fan noise on the TX650 but I believe it's a marginal issue i.e. not present in all units, perhaps someone has more accurate info on that.

NZXT HALE82 650W
Thermaltake Toughpower XT TPX-675M 675W
SeaSonic M12II Bronze 620W
Cooler Master GX650 650w
Cooler Master Silent Pro M600W

These are also available in the 600W range.

Forget about Coolermaster GX650 and Thermalright. The other three (four if counting TX650) are better quality.

How much is the NZXT hale in comparison to the others? It's also manufactured by Seasonic but unlike TX650 V2 is has four PCIe connectors and the cables are modular and full-tower length (so not really relevant to you). If it's cheaper than the M12II and Silent Pro, pick that one. If not, the M12II would be a better choice, and it's always a bonus to be able to rely on Seasonic's (from what I hear, exceptional) customer support if there are any problems with the PSU.

NZXT and Seasonic are both priced at 100$ cheaper than the rest by 10$.

Alright. If you want to have the cables for SLI/crossfire buy NZXT, although it is insufficient for GTX580 SLI (but will support lower tdp options like GTX 670 SLI or even 680 SLI, and of course later generations). Otherwise get the Seasonic. Was the TX650 also $10 more? And how much would S12II 520W cost - enough to bridge some of the difference between used 580 and new 7870?

It is almost 30$ less.

Are all coolers the same? Remember that I am in Egypt and summer is coming with >30 degrees Celsius and Ivy bridge is probably going to dissipate more heat than usual.

Ivy Bridge CPUs are at most 77W TDP, so they will run cooler than the already cool-running 95W Sandy Bridge chips. I've seen that big OCs can get hot, but that's to be expected.

I'll go with the TX650 and Hyper 212 plus since they are available on the same store with the rest of the components so I might be able to get a discount.

I thought the speculation about them running hotter was due to having a more concentrated die. So even if they produce less waste heat, it is concentrated on a smaller area, resulting in higher core temperatures; or at least, that's the speculation. We'll have to wait and see

That's true, but the TDP is lower as well. The 77W also factors in the iGPU, so the CPU portion is really only 65W. It would depend whether the ratio of TDP:core area has actually changed.
