Corsair HX1050 Power Supply Review

The HX1050 makes for a fantastic addition to the Corsair range of award winning power supplies. First impressions are very positive, with a substantial bundle offered, including a handy felt bag for cable storage. The flat, modular cables not only look great, but they help to reduce air friction, increasing flow throughout the chassis. The paint application and overall build quality is without fault, much as we would expect from a Corsair branded product.

The Corsair customised CWT design proves well balanced – delivering excellent load regulation and stable delivery under cross loading stress testing. The high levels of efficiency surpass 80 Plus Silver certification and the large, high quality 140mm Yate Loon fan ensures adequate airflow while keeping noise emissions to an absolute minimum. Only at the top 20-25% of load does the supply become audible and even then it will be drown out within the majority of performance enthusiast based system builds.

Noise suppression is stellar with both +3.3V and +5V output peaking at 15mV, while the +12V output hits only 30mV under full load conditions, well within the rated tolerance guidelines.

The HX range look to be very competitively priced, with this HX1050 unit retailing for around £160 inc vat in the UK. This means it earns our highest award, being one of the finest power supplies in the respective price bracket.


  • Great build quality and appearance
  • exceptionally quiet
  • custom CWT design is fantastic
  • All round performance is stellar


  • Its only semi modular

KitGuru says: a Monster 1000W+ power supply and well worth the reasonable cash outlay, especially if you can’t afford the range topping AX units.

Rating: 9.0.

Surely not another great power supply from Seasonic, tweaked and upgraded for 2018?

    another winner by the looks of it, nice price point. I remember I paid the same for a 850W. even if it was gold certified.

  • Brooke

    Their PSU’s are great, still have one I bought a few years ago, its been on 24/7 for two years now.

  • Frankinberger

    ill be looking at the 850W in this range in a few months……… hopefully its priced well (ideally £120 or less!)

  • k0rn

    hard to fault their power supplies. Quick question,. are they really a custom design or do CWT just build them to specification for corsair?

    I read on another site that Corsair get the CWT designs and then tweak it ‘in house’? this would mean it is a more a Corsair/CWT joint design right?

  • Davis

    Excllent, another good one for a more mainstream audience

  • Thomas

    I need a new psu, 850w just as good in this range?

  • Peter

    Not for me, i boight their 1200w ax psu in jan, love it, great for my sli 590s

  • Colin

    I can recommend their power supplies, I have an AX and I love it.

  • Forrest

    They dont often drop the ball, and although they dont really seem to make anything themselves, they work with some great partners and force high standards.
