Cooler Master GX 450 Power Supply Review

Cooler Master have chosen the ADDA AD1212MS-A71GL, a 120x120x25mm sleeve bearing fan which is oil impregnated and operates between 10.8 to 13.2 V. Start up voltage is 7.0V DC nominal. It requires 4.08 watts and rotates up to 2,050 rpm generating a maximum of 80.5 CFM. Noise ratings show a maximum of 38.0 DbA.

On the upper heatsink there are two black heatshrink sleeves over the fins, these are used for fan control and overtemperature protection thermistors. This is a dual forward design offering up to 85% efficiency.

The PCB is a clean design and the capacitor is rated to 105c, 330 uF, 420V.  It can produce a hold up time of 17ms when fully loaded.

The cabling is fully sleeved into the chassis and is well protected against possible long term fraying.

    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

    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.

    Price will be around £40 – £45
