Corsair TX750M PSU Review

Protection Features

Check out our PSUs 101 article to learn more about PSU protection features.  Our protection features evaluation methodology is described in detail here.

Protection Features
OCP12V: ✗
5V: 34.2A (137%)
3.3V: 35.0A (140%)
5VSB: 5.6A (187%)

PWR_OKOperates properly

SIPSurge: MOV
Inrush: NTC thermistor & bypass relay

The OCP thresholds on the minor rails are where we'd expect them to be, given our experience so far. However, the 5VSB rail's OCP point should be set lower in our opinion.

OPP is a little higher than normal, while OTP looks low. But we didn't encounter any problems during our high ambient testing, so this protection feature probably won't cause any unwanted shut-downs under real-world conditions.

As expected, short circuit protection is present on all rails, and the power-good signal is accurate.

    I have one of the 'sister' versions of this PSU. I like it a lot. My case is all air cooled, so I never hear the fan on the Corsair.

    So I guess this is a "re-release" of the TX-xxxM semi-modular line?

    I have one of these ^ sitting in a box somewhere. Not that bad a unit but I hope they don't go through another "V2" fiasco with thise new line. If memory serves, the last time the issue was attributed to using a newer OEM manufacturer...

    Great review though! Very thorough and well presented :)

    Thanks for the review Aris, it looks like with a few tweaks, this platform could really kill it

    Got a TX-750w 9 years ago.
    Still going great!

    Any chance to review the new CX series released by Corsair recently. Not the M , but the non modular CX.
