What is a gigahertz power supply....power is measured in watts. Also, if that is supposed to be 2x1200GigaWatts, well you would need the combined output of a few thousand aircraft carriers to do that.

More on topic though. More power wont hurt your system, but it will effect its efficiency. Most power supplies operated at peak efficiency at around 75% max capacity, because that is where most people use them. As you move away from that point your efficiencies will drop. Now, that being said, that isnt a bad thing per say, but you will be paying more per month to operate your computer to the power company.

A good rule of thumb is to get a power supply that will supply 25% more than what you need for a few reasons. One is to prevent underpowering your system if your psu isnt performing up to snuff. Another is to give you room for future expansions. In your case, I would get a psu that will give you ample power for your future build, but not something overpowered.

As it has been said, a QUALITY 650W power supply should work wonders for you now. If you find yourself needing more power, you can always upgrade down the road.

If I got something wrong here Im sure someone will correct me, but Im fairly certain I got that right.

If you want to make a rig with a good "bling" factor a P/S that has "1200W" painted on the side looks pretty cool. Some people like big numbers and overkill (and I don't judge them harshley because of this). Don't get the idea that a high capacity P/S can shove a damaging amount of power down your PC's throat,it does not work like that.

I have my one 1000w P/S,everthing else is closely tied to what is actualy needed. I do have a couple of 850's that were bought simply because the price was to good to turn down

I'll more than likely go with a SeaSonic X650. I like the fact that it is Fully Modular and it's proven high quality. Plus, if you think about it, the trend of future tech has been less power consumption/more performance which could make the 650w futureproof? Just a thought...

I'd go with the Antec but I can't find any specs on size and its not fully modular. However, it would save me some money...


And to PCCstudent, buying a giant power supply for no reason would just a waste of money. I'm not building a computer to impress anyone, I'm building a computer so I have all the features I personally want with the satisfaction that I put it all together myself.

Many people do express their creative or "artsy" side of themselves through the way they make their P/C look. If the theme you have in mind for this PC is one of power the 1200W P/S helps with reliizing this theme. Again, I don't speak negativily towards people who use the look of their PC to express themselves.

I guess you could just paint up a 400W with some fancy logo, but to each his own.

Fully modular is unnecessary. Since one will ALWAYS be using the 24pin and 4 or 8Pin EPS CPU connector anyway who cares if it is modular or not. It isn't going to save you any space or provide any extra functionality. The only cables that need to be modular are the SATA, Molex, and PCI-E connectors.

A quick look on the Antec Website reveals that the size of the unit is as follows. Took all of 30 seconds to find it.
Dimensions:
- 3.4" (H) x 5.9" (W) x 5.9" (D)
- 86mm (H) x 150mm (W) x 150mm (D)

As for proven quality, it is a VERY HIGH Quality SeaSonic. It's as good as any of the others you mentioned.

So are the only cables on those (semi)modular PSU's just the 24pin power cable? I was thinking there were others... But if that's the case then I'll definitely go for that 750w PSU.

As I said in my previous post, normally just the 24pin and the 4/8pin EPS CPU cables that you would bu using anyway. You would have to check to be sure for any specific PSu, but that is the norm.
