MAJOR points to corsair for reaching out consumers in this way.

I've seen various products change a bit in the past. I never knew it was proper for a company to announce things. I just saw it as a bonus.

The more you reach out to your consumers to take input shows you have confidence in your product and your willing to evaluate based off production feedback.

EDIT: fixed some bad english.

Props to Corsair for posting but this thread is worthless without a graphed comparison between the two layouts. More specifically, showing ripples, temps and efficiency would be nice. smile.gif

Glad to see a response form someone at corsair, thanks for your input.

No kidding. Where are the "Intel CPU: Finding the truth" threads whenever Intel comes out with a new stepping (which isn't always "better") and the CPUs are still sold with the same part numbers? Same thing happens with graphics cards too.

Totally agreed!

Revisions happen all of the time in the real world. At least Corsair have taken notice of this uproar and are directly addressing these concerns. They don't owe you anything as that is how the rest of the world works. You could go to a local bakery and they could have switched out your source of coffee beans or flour, and you wouldn't know the difference unless they told you.

I work in a depot maintenance department for a retail chain and I can't tell you the number of times our hardware supplier has changed parts on us. Unfortunately, that's how supply and demand works. We're not the only company that they deal with, and when supply runs dry they have to immediately start shipping out comparable replacements. Considering that the new parts usually work better or last longer anyway, it's not a bad trade-off.

Whether if what Corsair has changed to will stand the test of time remains to be seen, but at least the warranty is still intact should you actually need to use it. Yes, it does suck if you are in that situation, but at least you won't be stuck with a paper weight for long. If they changed that for the worse along with the switch in platform, THEN I can see a need for concern.

Thanks for the post! <3 Corsair.

Just a few questions and suggestions.
A few months ago, I bought a 650 unit that died the next day after arrival.
I sent it back to Corsair and when I got it back it was the new 650-C unit. You guys replace RMA'd old units with the -C ones correct?

Another point. Are the new units any different in size? or just the fan is bigger?

and a suggestion! The corsair "pouch" that the PSU comes in was a LOT better quality on the old 650 units ;D

I didn't really mind getting the new one made of less soft cloth, but I sure regretted sending out the old pouch with the broken unit lol.

I don't see the big deal quite honestly

Just like to clarify why we're accusing the PSHII models of having lower build quality:
- Much smaller heatsinks (more prone to overheating)
- Less robust transient filter (one fewer coil, one pair less Y-caps, think there are a couple other fewer)
- Single layer PCB (instead of 2 or 3 layer)
- Less primary side capacitance (lower hold-up time, etc.)

There's also the fact that the +12V rectification is done by six parts instead of two. This means the odds of one part failing are three times greater; but if one does fail the damage will be less than with just two. So we'll call that one even.
Come on. What's with you lately?

- Much smaller heatsinks (more prone to overheating)
Since those same heatsinks are used on the 950W DSG, they will have no issue keeping the 750W PSHII cool.

- Less robust transient filter (one fewer coil, one pair less Y-caps, think there are a couple other fewer)
As far as I can tell, the exact same input filter is used on the DSG. Again, where was the outcry then?

- Single layer PCB (instead of 2 or 3 layer)
If it will all fit on a single PCB, what's the big deal? I've seen many PSUs with dual layer PCBs with only a few traces on the top. If they managed to organize it so it all fits on one side, how it that of a lower quality? Maybe there's something I'm missing.

- Less primary side capacitance (lower hold-up time, etc.)
The reviews I just looked at has the PSH TX750 using a 390uF 400V Matstu****a and your pic of the PSHII TX750 uses a 470uF 400V cap. Am I missing something here?

You also have a comment floating around about how six 12V MOSFETs are much more prone to failure than two, but again I don't see you raking Enermax or Enhance over the coals with their eight MOSFET 12V rectification.
