Power Supplies: Corsair 750HX worth $50 more than 750TX?

Hey guys, I'm currently trying to decide on the very last piece for my new computer: the power supply.

After quite a bit of reading, I have narrowed my choices down to 2 options: The Corsair 750TX and the Corsair 750HX. I like the sound of a modular setup, and I know the HX is an even better PSU than the TX, but is it worth $55 more dollars than the TX? I'm very tempted but my build has already gone over budget, and I'm just a little hesitant on this one. Please let me know what you think, and thank you :).

  1. Imo, unless you NEED a modular PSU due to case size,etc go with the 750TX. Both are based off of the same stuff internally (more or less).
  2. Thank you for the quick reply.

    On the other hand, I just want to say I ran into the "Antec Truepower New 750" and it also seems to be well reviewed. I have heard that Antec quality has been going down lately, and was convinced of the quality of the Corsairs (and still am) but this seems interesting, is partially modular, and costs only $10 more than the Corsair TX ($40 less than the HX). What do people think of these?
  3. ^Actually, the Antec TPs are quite good.

    Check out the review here (I believe this is the model you'r talking about?): http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story4&reid=140

    If you don't know, Jonny Guru is the #1 source for PSU reviews.
  4. Afaik antec quality is actually improving.
  5. I have the Corsair 750WATT TX PSU.

    If I could go back in time, I would have purchased the modular.

    IT is very hard to get good cable management with the 750TX's large black cables. There are many cables, which is good if you have alot of things to plug them into, like dual cards, and many harddrives, but it wasa bit over kill for me.

    I do appreciate the single 12v rail though. It's a great powersupply, I would just rather have the modular for the aesthetics.
  6. Hey guys, thanks for the additional replies.

    That reply at Jonnyguru's was actually the one I was reading when I said I had been alerted of the Antec Truepower. The Truepower actually seems like a nice compromise between the Corsair TX and HX--partially modular, and well priced. I am this close to going with it but I have heard that some of its cables are too shrort, which is too bad. I don't really want to have to stretch cables across my video cards, pci cards, etc. Specifically I have heard that this can be a problem with the cpu power cord if you have case with a bottom-mounted PSU, which I do (the Antec 902). Can anyone confirm or deny the length of the Truepower's cords?
  7. Almost every bottom mounted PSU has a too short CPU power cable when it's run under the motherboard tray.

    That's true of my 550 and 750 watt Corsairs and my 550 watt Antec in my 3 900's.

    I solved the unused cable clutter problem by drilling some extra holes under the lower drive cage and tying the unused cables down.
  8. That's a good idea.. and I think the "unused clutter" on an Antec 750 could be easily solved as there shouldn't be too much of it. It's hard to resist saving about $45 at this point for a PSU that performs very closely to the 750 HX.

    What do you normally use to tie unused cables down? I'm sure that's a simple answer but I'd still like to know what others depend on. Thanks mate :).
  9. Twist ties, zip ties...
  10. ^ Yup. Zip ties FTW!
  11. rats, one other question.... can the Antec 750 handle 2 5850s or 5870s in Crossfire--meaning does it have the requisite PCI-e connectors (4)?
  12. yes
  13. Great. Thank you to all for your welcome replies and assistance.

    If anyone is willing, I have just one more question to soothe my own curiousity. I see some PSUS have 6 + 2 pin PCI-e connectors, and some have just 6 pin, and some have both. What is the difference between the two? Do the 6 + 2 pin connectors sitll work on 6 pin connection slots?

    Thanks again :).
  14. theres are 3 kinds of pci-e connectors: 6 pin, 6+2, and 8. basicall, a 6+2 is an 8pin where 2 pins are removable, to act as a 6 pin.
    6pins can provide half as much as 8 pins, but a 6+2 pin can act as both
  15. When you say 6 pin can provide half as much as 8 pins, do you mean they provide half as much power, but you can still use them in an 8 pin slot?

    ie. If I have Crossfired 58xx cards, each requiring 2 pcie connectors, could I use one 6 + 2 pin and one 6 pin in each, and still have a safe and stable power flow? You'll have to excuse me--I'm obviously still a newb when it comes to power supplies.
  16. no. use what it needs. if it needs 2 8pins, use 2 8-pins. if it needs an 8pin and a 6pin, use that! do not use less than it needs.
  17. The HX is silver rated, high effeciency compared to the TX, and the HX DOES have better quality capacitors inside (both are solid instead of just one on the TX)

    I don't have the links on me, but I found it all when I was buying the 750HX. From corsair's website:

    HX: Supports ATX12V 2.3 and EPS12V 2.91 standards. Backwards compatible with ATX12V 2.01 and 105°C solid-state capacitors

    TX: Supports ATX12V v2.2 standard and older ATX12V 2.01 spec and High quality Japanese capacitors provide uncompromised performance and reliability.
  18. well the xfx 750 is just as good if not better then the hx750 an tends to be a lil cheaper you could look into that but the tp 750 from antec is just a mm behind them in quality terms
