Corsair TX - Finding the truth

post #1 of 64
Thread Starter 
Read carefully before doing anything

Foreword: As mentioned in my other thread, Corsair has changed their TX line of power supplies in secret, replacing them with models with cheaper build quality. The purpose of this thread is to see what units were affected, when the change took place, and if there are any alternate versions that we have not yet been informed of. My anonymous source reports a third variant, a CWT PSH with modified components. I'd like to see if we can spot one in the wild.

Goals:
1.) To identify which Corsair power supplies were affected by this change
2.) To identify the approximate timeframe in which these changes took place
3.) To identify what the older units were replaced with

Models we're interested in:
Corsair CMPSU-450VX (VX450)
Corsair CMPSU-550VX (VX550)
Corsair CMPSU-650HX (HX650)
Corsair CMPSU-650TX (TX650)
Corsair CMPSU-750TX (TX750)
Corsair CMPSU-850TX (TX850)
Corsair CMPSU-950TX (TX950)

These models have been chosen as being the most likely to have been modified. Several we are more than 90% certain have been changed; others we honestly don't know, and a couple are controls that have almost certainly *not* been changed.

If your Corsair PSU is not one of those model #s, then I do not care. ONLY post if you own one of the PSUs listed. I do not care whatsoever about the CX, GS, or AX lines of power supplies, or HX models aside from the HX650. And I *most* definitely do not care about power supplies from other brands.

Additionally, Only post if your PSU was purchased on or after JUNE 1st, 2010


Methodology: Very simple. No disassembly required (**though it would be helpful--see below). Simply take a picture through the back grille of the power supply so we can get a view of the internal components. Myself and the other gurus will identify the platform that the PSU is based on (anticipated platforms: SeaSonic S12, S12E, S12II, CWT PSH, PSHII, DSG) Once we have a good baseline for comparison we'll add pictures to this post. Then those of you who lack cameras, can't get a good enough picture, or whatever, can compare visually your power supply to the ones pictured to ID the platform.

**If you are feeling adventurous and don't mind voiding your warranty, it would be particularly helpful if you could open up your power supply and take some pictures of the internals, and if possible ID the major silicon components (a dental mirror is helpful for this).

When you post your picture / ID the platform, please also provide the date of purchase of your power supply and the location purchased from (ie. "Newegg.com, 10/6/2010" or "Fry's Electronics, San Jose, CA, 7/?/2010"). If you can provide the serial number, that would also be helpful.

I will collect the data in spreadsheet form and look for trends.


Hypothesis: I suspect that we will find that at some point during Q3 2010:
1.) 90% confidence: Corsair TX750 and TX850 were modified from CWT PSH to CWT PSHII
2.) 90% confidence: Corsair TX650 was modified from SeaSonic S12 to CWT PSHII
3.) 90% confidence: Corsair VX450 was changed from SeaSonic S12II to S12II Bronze
4.) 70% confidence: Corsair VX550 was modified from CWT PSH to CWT PSHII
5.) 50% confidence: Corsair HX650 was modified from SeaSonic S12E to CWT PSHII
6.) 90% confidence: Corsair TX950 remained CWT DSG






So let's see what we find. Go!

Are there any other identifiers like serial numbers, product code, or inspection date that could be used in addition to purchase date?

Also, is the UL number different then?

UL number will likely remain the same, except perhaps for the TX650 and HX650.

Serial #s would be helpful as well.

Wait, if I can see a yellow MOV between 2 coils, it's the PSHII?

Yeah, all the TX models, plus the VX line and the HX650.

The yellow is actually an X capacitor, but if it's coil-cap-coil then it's a PSHII, but if it's coil-coil-cap-coil it's a PSH.
