If your system had a short, you would want the system to lose power as soon as possible. Continuing to deliver power to a shorted component would not only be a fire hazard, it could also damage other components that are dependant to it.

Also important is that his cpu is made for overclocking The vga-cards are also made for overclocking. So guru 3d may have been running a substantial overclock , he will probably overclock too. Not to mention all those little power eaters, like usb devices, leds, card readers, fans. It's not much but it all ads up. GS550L
Guru3d's test system contains multiple hard drives, an above average amount of fans, CCFL's, and a liquid cooling system, all of which qualify as "little power eaters" and make for an accurate representation of a system that's fairly loaded with extra components. Plus, consider that the power draw was measured off the wall, which means that after taking into account the efficiency of the power supply, the actual power draw from the power supply is lower than the 720W value given by Guru3d.
Even if at a certain point in time he wants to upgrades cards, it could be possible they draw even more power. All in all , too much advantages for only 30$ more. Too much risk for only 30$ less.evildead6789
That's true, but at the same time, the OP should ask himself what kind of power draw he's willing to tolerate. From my point of view, 700W is a very high power draw considering that my humble system (Athlon II x3/twin 4850 512MB), which scarcely pulls 450-500W, is capable of heating up an average sized room to an uncomfortable level. Also, consider that with a power draw above 850W, the OP would likely have to invest into an extravagant cooling system, as most air-cooling solutions would not be able to effectively deal with that kind of heat-dump
You quote me on the shortouts while i pointed out it wasn't that important, the other argument namely a durable and long lasting system is more important.I repair pc's every day and the most broken pc's come from broken psu's. The reason is mostly because of low quality and/or low power psu's.
Besides , a fire will not start because of the higher power psu. The 1050 W has over-current protection too.
Who says he won't use extra harddrivers, usb printer, extra fans or whatsoever. When you choose lower power psu's you're cutting away the extra room you have. besides guru 3d used a 1200W not a 1050W.
The review of techpowerup says that two gtx 580 card can go to 627W before the limiter kicks in, that means at a certain point in time, it will draw so much power. and these are just the cards alone. Again headroom is important.
As for future cards power and heat i don't know what power they will use, but if he's willing to pay 2200$ for a gaming system today, i highly doubt the extra heat that the cards and psu produce will stop him from buying newer cards. But this is not the main reason, if the newer cards draw 100W more ok but if it would be 250W more i would advise to buy a 1200W psu. Again for the main reason, durability.
And that's the biggest issue here, durability, i believe in it, you don't. The rest are all extra's , the only downside is the 30$ more. It's up to the OP to choose.
