Modular PSU - worth it?

I'm torn between a Corsair TX750 (standard) and a AX750 (modular). The AX750 is more expensive of course - around US$ 80 more around here.

Do you think I should go ahead and buy the modular one? I want a PSU that can last, and I'm sure it's easier to manage all the cables with the AX750. But does it justify the price premium?

Thanks.
 
The differences between the TX and AX go well beyond modularity.. the TXv2 or TXM are mainstream units while the AX is a premium unit with superior efficiency, superior components and build quality, and also a lot quieter.

However, the system you have listed in your sig requires a 400W PSU not a 750W one, and especially not the AX which is a high end part that makes sense in a high end rig;)
Get an XFX Core 550W, it will save you money and is overkill anyway :)

Even considering I plan to upgrade later? Of course I wouldn't be using two+ GPUs or anything... at most a Core i7 with a top-end Radeon + 16GB RAM and stuff.
 
Core i7 with a top-end video card with lots of overclocking and overvolting would max out around 550 watts or less.

Your present system consumes <300W in gaming and pretty much anything else except synthetic benchmarks where it will approach 400W.
A 500W PSU is enough for pretty much any single GPU system you can think of, except maybe a GTX480 and/or Gulftown(Intel Hexacore).
So, the 550W suggested above is made by Seasonic, like both Corsair units you asked about and is a good quality, solid PSU.. it will have no issue powering whatever you throw at it as long as you stick to single GPU solutions.

Microcenter has an even better offer on this Antec HCG 620W @ 50$ after rebate, which is also made by Seasonic.
If you want something modular you can get the Rosewill Hive 550W for 70$ after rebate, the cheapest solid modular unit available.

If money is not such a big issue and you're willing to spend 100$, the Lepa G700 is an excellent deal, Gold rated, modular, Enermax 87+ inside.. anything above that would be a waste of money considering your intentions.

I don't overclock, so I guess 550W will be enough.

About the XFX PSU: Is it the Xfx Core 550w Pro P1-550s-xxb9?
 
Yes, it is.

If you're looking on Newegg, I would probably spend the $5 more and get the 650 watt version.
 
While it's pretty true that if you have no plans of sli/xfire or anything else out of the ordinary, your psu needs aren't that high, to address your original question of modular psu's:

The more accurate comparison would be between say the TX's and the HX's, as there isn't the large premium incurred by the AX line because of the AX performance gains and gold rating. In the case of the HX line, they usually run an extra 10-20 for modular option and sometimes better performance over the TX. For the convenience factor, ease of runs inside the case, and general cleanliness (especially if you're taking the time and effort to work on cable management), I'd say it's worth it.

If, on the other hand, it's a budget build that's getting slapped in the case and sealed up, and you're looking for places to trim fat, it's one of the earlier things to cut, simply because modularity isn't really a performance option.
 
The HX line is superior to the TX line in every single way, and incurs a $30+ premium unless there's a special sale or promotion.

The TX-M is what can be compared to the TX V2 line. The TX-M is the modular budget version, with slightly worse performance than the TX V2, and incurs the $10+20 premium for modularity.
 
The Seasonic X series are pretty cheap on Newegg -- the X 560 is
118$ shipped... the shipping is free. You can't go wrong with any of the X series. I'm thinking of replacing my X650 with the X400 fanless model.

You are 100% right. Sorry, posting late and my quick newegg look-up's were apparently a little too quick.
