hey everyone, i wanted to know which PSU is better. Better as in which one can take more heavy hardware. Price is not an issue, thanks.

Though if by "heavy hardware" you mean using dual hi end GFX cards and and OC'ing, I'd be:

It depends on your budget and the type of Rig you want to set up.
If you're not much into gaming and more focused on office and other
image editing and web design applications and will probably buy a
"not so high end procie" like those i7 extreme edition ones
and a single video card (e.g. like those ATI's 4670, 4770, 4850,
4870, 4890 or Nvidia's GTS250, GTX260, GTX275, GTX280, GTX285).
Well, the much cheaper CORSAIR CMPSU-650TX 650W is your best choice.
Aside from being much cheaper than Coolermaster's Silent Pro Psu you
indicated as an option, you'll have the latest features and innovations
that Corsair offers and can be found on their very high end expensive models.
Also as indicated to one of its features,.. Its ultra quiet.


Hope this Helps :)

im pretty much gunna be using 1 powerful video card such as the hd 5870 or maybe the gt300's when they come out. I know the 650tx would suffice but what about for headroom? Wouldnt the cm 700w be a better choice vs the 650w?

I also heard that the CM has 50 amps in total while the corsair has 52 amps. Does that mean the corsair is the better choice even though its 50w lower?

Corsair

The general rule of thumb is a high quality 500 to 550 watt power supply with sufficient current (amps) on the 12 volt rail(s) can easily power a system with any single video card made. A high quality 700 to 750 watt power supply with sufficient current (amps) on the 12 volt rail(s) can power a system with two video cards operating in dual mode. There are a few exceptions like the new ATI Radeon HD 5XXX series cards which use less power due to their energy efficiency.

Before purchasing a new psu you will need to decide whether you will eventually have a pc with one or two video cards.

Corsair, PC Power & Cooling, and Seasonic are some of the brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Lately we've been seeing a few other brands offering some high quality units.

Even if you'll be gaming on a single very high end video card still, that
CMPSU-650TX 650 watt psu is more than enough for your system's
continuous computing needs, even if your procie is an i7 extreme
edition one and even if you crossfireX two 5870 RADS (except SLI'ing 2 GTX295
or 2 GTX285 or 2 GTX280), that Corsair 650 watt psu is still enough.

When it comes to amps, a 2 amp difference wont matter if the psu is capable
or designed to handle very high end systems and certified by the manufacturer
up to the point where it can provide power to its specified limits (e.g 2 video cards,
etc..)

I'd stick with the Corsair as well.

With this single card be a single or dual GFX chip ?

Look at the 4870x2 and the GTX 295 for example. Though they fill a single slot on the MoBo, with those I'd use an 750 or 850 watter. These save a bit of hassle when using multiple monitors where redoing the settings is oft necessitated. The 5870x2 is anticipated around thanksgiving though I wouldn't expect the nVidia one till after XMas.

Ideally, your PSU should be picked to age with the machine.....so accounting has to be made for each USB / IEEE 1394 / e-SATA thingie you connect to the box (mouse, KB, Camera, printer, USB stick, etc) as well as maybe a more powerful or extra vid cards in future (I.e. SLI, Xfire, PhysX), and let's not forget capacitor aging.

And let's not forget that most electronic devices are most efficient at 3/4 load, whic is where you wanna be during everyday use. Remember if you are at say 85% eff. at 3/4 load and 75% at 9/10 load, that extra 5% is being turned into heat.

Really wish we could, but people keep bringing it up.
It is a fact, capacitors do age, but they don't do it in a lineal fashion.

I've seen plenty of blown caps on 3 and 4 year old 450w psu's that were running 24/7 and, at the opposite end of the spectrum, have 7 and 8 year old Dells with 200w unit's still humming away 24/7.

Buy a known good quality psu and don't worry about cap aging.

Of the two PSU's that you list, the Antec is a better unit even if the output is 50 watts less.
