It sucks to have to buy a new psu to upgrade GPU.

I had this happen, no fun.

One point that a lot of people are missing here when it comes to recommending a smaller PSU. Everyone keeps saying it's a waste of money to get one if you decide at a later time to add an additional vid card and go SLI/CF, or make some other high draw upgrade that would require replacing that PSU with a higher powered one. That's completely incorrect. Think of it this way, how many threads do you see here on OCN where someone is having a problem that they think is PSU related, but they don't have another PSU to test it with? While that high quality 500watter may not power the system in full triple SLI mode, it would be more than adequate to power up the system with one card to test i he system with. It sure beats going out and buying a new PSU just to do some basic testing with (and no, getting one and then returning it is NOT a viable or ethical option).

Also, after two years when you do decide to upgrade there is a good chance that the new hardware will use LESS power than what you currently have. The idea of future proofing is a myth. Phaedrus's reasoning is if they don't have a definite plan to add the additional upgrades then the chances of them doing so it rather small, otherwise they would have mentioned it in their post. A simple response of a good quality 500 watter (or whatever wattage meets the hardware specs) from the Recommended PSU List would be an excellent choice for your current setup. Then add that if they have a definite plan to upgrade their vid cards, go SLI/CF, etc. then a 650, 750, or whatever might be a good option. To me that is a more responsive reply to their post then just saying get a 750watter just to make sure you have enough. Doing that is as bad as relying on a PSU calculator to determine what they need, especially since most of the people making those recommendations don't have any idea about what they are talking about.

Alot of psu's arent what they are actually rated , a cheap 650w psu is more like 450w .

A quality 750w psu is good for any non sli system .

I had problems with my 650w , in benchmarks my pc would just switch off .. due to lack of power since i have everything overclocked .

Now i have a 1000w it doesnt happen anymore , i bought 1000w because i will probably end up xfire soon and i have a milion and 1 fans and lights in my case .. every bit helps .

While I agree that cheap/bad PSU's aren't always what they're rated, you are entirely wrong regarding to your usage of wattage.

Your 650W made your system switch off because the PSU sucked... Not because of wattage.
It's not just the wattage of a PSU but amps and decency of a PSU. 1Kw is WAY overkill for your current system. Your system never draws beyond 500W unless you have extreme OC with top end watercooling - then it may be 540W at most...
Not to mention a decent PSU will in many/most cases supply even more than peak rated wattage to your system. Some 500W PSU's only fail when they are to deliver 650W. I don't make these things up, this is knowledge based on PSU reviews and experience from consumers.

I belive Google would be suited for you. No offense, but you need it.

I remember the thread where you posted about your problems. As p4p3r said your problem was a cheap piece of junk PSU that couldn't produce anywhere close to it's rated power that was causing the problem. You could have replaced it with a smaller rated QUALITY PSU that put out it's rated wattage and your system would be running just fine. You only needed about 500-650 watts at most, not that oversized thing you wasted your money on.

And I can't see any single GPU system that would need a 750watt PSU. There simply isn't a cpu that would require it, nor enough fans, lights, and other bling bling that you could add to it that would need it.
