My friend is confused between these two for a new build.Corsair 620HX and OCZ SXS 700w.He is getting these two at nearly similar prices.
Which one is better between these two?
He may crossfire high end gfx cards like 5870 or 5970.But he is on single card right now.

Specs he will have
PhenomII x6
4 gigs ram
2 hard drives(1 tb + 500 gb)
1 optical drive

There should be no question between the two, Corsair.
Your friend won't be crossfiring the 5970 on either of them and should be looking for more power to crossfire the 5870.

Of the two you mention Corsair is the better option. What is the actual price they're going for? It would be rare to find them the same price. When I checked I saw Corsair @ $130 (wayyy too high IMO) and OCZ SXS 700 @ $90 or $65 with rebate.
There maybe better options out there.

But what about the higher wattage on ocz?
i know corsair is far much better and its HX620 can deliver around 730W and ocz sxs 600(not 700) can deliver 715W (as per reviews on hardwaresecrets.com).

Unfortunately actual watt output for 700W models aren't available.
but based on those reviws,we can assume that ocz 700w will have more than rated power.so why not to go ocz for future needs like crossfire or a corsair 620 will be sufficient for his needs?

To crossfire the 5970 or the 5870 you better get at least an 850 watt unit to power those cards the two units you listed would be fine for 2 5850's but the 5870 and 5970 are much more power hungry.

Unfortunately ocz isn't available in our country,he is getting ocz by an international reseller in $105 and corsair(available locally) for $131.
So we are thinking that ocz isn't a bad deal for 700w at 105$.also there will be no psu available at this price point except ocz.also ocz has got nice reviews.
what to choose between,we can't decide.

will the above two units be able to power the single 5870 or 5970?

You should not make that assumption. Check and verify that it can actually do what it claims, and do it well - like not having excessive current ripple at high load levels. The quality of the power can be just as important as the quantity.

Here is a OCZ StealthXstream 600W Power Supply Review from Hardware Canucks. Usually a similar model in the same family has the same performance characteristics.
What got a good rating back in 2007 would only merit an 'average' rating today, IMO.

Here you have the Power Supply Requirement for the HD5970: 650 Watt or greater power supply one 75W 6-pin and one 150W 8-pin PCI Express® power connectors recommended (850 Watt with two 75W 6-pin and two 150W 8-pin connectors for ATI CrossFireXTM technology in dual mode).
If your friend is thinking about doing 5970CF, I would go for one of the following PSUs:

Corsair HX850 (by CWT) (modular)
Corsair TX950 (by CWT) (non-modular)
XFX Black Edition 850W (by Seasonic)
Enermax Revolution85+ 850W
Seasonic M12D 850 W (It's the same PSU than the XFX Black Edition)

If he decides to do 5870CF, a good 600W PSU would be enough. Anyway, I would go for one of the following PSUs:

ANTEC TRUEPOWER NEW 650W (by Delta Electronics)
CORSAIR HX650 (by Seasonic)
CORSAIR TX750 (by CWT) (although its electrical noise level is not the best possible)
SEASONIC M12D 750W
XFX Black Edition 750W (by Seasonic) (it is a relabeled Seasonic M12D 750W)
ENERMAX Modu87+ 600W
SEASONIC X-650 650W
THERMALTAKE Toughpower XT 775W (by CWT)
