im looking at new egg it seems like the antec 550w is the same price as the 750w so why not the 750w
post #12 of 41
The HX series is generally quite a bit better than the TX series in terms of quality, especially when it comes to the 750W and 850W models. The TX units are based on an old CWT platform with average efficiency, mediocre ripple suppression, and good voltage regulation, whereas the new HX units use a brand new CWT platform with excellent efficiency (certified 80Plus Gold), and excellent performance across the board.

In practice, any of the TX or HX series PSUs will be able to do their job perfectly fine. However, the HX line does have much better performance, and also much better efficiency characteristics which is a very nice thing to have.

The newer Designation of TX is to make it an easier way to separate the two different quailty units.

I almost always agree with Two Cables on everything but this. I think that with power Supplies there is no such thing as overkill. More is better always. You would rather have a huge PSU in a small system and do whatever you want in the future than to always be replacing a PSU everytime you upgrade just to save 50 or a hundred bucks. I have an HX 1000. I don't need but 675 watts of it but I like having the power if I need it one day and if I don't, well I am not using anymore juice than my system needs.

New One

Old One

The new Corsair TX
Here is a review on the new Corsair TX850 V2
http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=218

I am pretty sure the new TX750 V2 is made on the same platform by Seasonic.
Like others said probably overkill but it’s up to you.


The CORSAIR Enthusiast Series TX750 V2 750W is $111.99 shipped $91.99 after MIR at newegg with the promo code EMCKGHH37

Correct, the TX750V2 is made by SeaSonic, as are the TX650V2 and TX850V2. At this point, no one should be buying the older TX series unless they're heavily discounted. Regardless, the Antec TP-750 is a far better value than the TX750V2.

And since the price of the TP-550 is stupid right now, which is highly regrettable, it makes no sense whatsoever to buy it.

More isn't always better, and overkill to that extent is just a pure waste of money. Who says you would need to change the PSU in the future for upgrades? Not everybody is going to eventually move to three or four GTX 580's. People usually have certain limits.

Myself, for example.... I have a HX450 powering my rig. I know I'm never gonna spend more than around $200 on a graphics card so why would I need anything more than what I have currently?

Efficiency also plummets at extremely low loads.

Phaedrus2129 taught me that there is such a thing is overkill with PSUs. Not only does overkill result in lower efficiency as compared to the "right" PSU, but the more overkill a PSU is, the greater the chances are of experiencing other problems due to the small load on the PSU. One such problem is major instabilities that always go unexplained resulting in several unnecessary RMAs and way too much human stress.

If you don't believe me, then ask Phaedrus2129. Here are two of his articles that explain how you are having far less efficiency 24/7 due to having WAY too much overkill:

On PSU Efficiency

PSU "50% Load" Myth

So don't disagree with me because it's the same as disagreeing with Phaedrus2129 because I am merely regurgitating the things I learned from him.


Note: AMD recommends a power supply with a 600W "peak" rating to power a system with two 5770s in it. Your PSU has a 1000W "continuous" rating. So, your overkill is extremely excessive, and so I'd be surprised if you've ever had 80% efficiency.

Not when dealing with facts, no.
