Cooler Master GX 450 Power Supply Review

Rating: 7.5.

If you are in the market for a power supply for your new media center, then today we might just have the perfect partner for review. Cooler Master have just released their GX 450 power supply which features a strong 12V rail, double layer EMI filter and an intelligent 120mm controllable fan.

We have looked at several Cooler Master power supplies in the past, and the quality has always been high. The new GX 450 will offer more than enough power for a performance system aimed at media and HD television gaming.


  • Compliance with the latest Intel standard ATX 12V V2.31
  • Single +12V rail provides ample power and strong resistance to any overloading
  • High efficiency design that meets 80 Plus requirements (85% typical)
  • Multiple protection designs (OVP/UVP/OPP/OTP/SCP)
  • High reliability (MTBF>100,000 hours)
  • Double Layer EMI filter reduces Electronmagnetic interference
  • Huge bulk capacitor for hold up times of >17ms when fully loaded
  • Efficient transformer that reduces 5Vsb power loss when the system is in an off/sleep state
  • EuP ready: To save most power consumption (below 0.5W in standby mode)
  • Five year warranty

    If they get it out around 45 quid, should sell well.

  • Tim

    Decent product for the price (if they hold it in line with the others in the range). looks decent.

  • Davvy

    biggest problem is if you spent 20-25 more you enter into a whole new class of PSU.

  • Roger

    Still saving up for a corsair 850w, ill pass on this one, but good for those who want a basic PSU for a basic system.

  • Derek

    The box is nice :p PSU seems alright I suppose, but its hardly sexy KitGuru review material is it ?

  • Terry

    All about the price in this case really. seems a fair deal for what you pay. well unless they release it for £80. lol.

  • Tech head

    I’m sure not everyone reading these needs a 1500w psu, seems pretty good low cost way to build a media system

  • Charles

    RS-450-ACAA-D3 = Enhance because of the D by Coolermaster.
    A= AcBel
    D = Enhance
    E = Seventeam
    J = FSP

    Transformer markings also indicate that it’s an Enhance built unit.

  • Tjerrik

    Price will be around £40 – £45
