Cooler Master Releases GXII Series Power Supplies

Cooler Master has launched an update to a series of power supplies, thus giving birth to the second generation of GX-Series PSUs. The GX-II Series PSUs are aimed at budget builds, yet still deliver a more than adequate feature set.

All of the units will feature the standard 24-pin ATX connector as well as a 4+4-pin EPS connector. The 450 W unit features only one 6-pin PCIe power connector paired with two Molex connectors, one floppy power connector, and four SATA connectors, while the 550 W and 650 W units feature two 6+2-pin PCIe power connectors as well as six SATA power connectors, three Molex connectors and one floppy power connector. All the cables are sleeved.

The power supplies all feature a single 12 V rail design, as well as all the expected safety certifications, topped off with an 80 Plus Bronze certificate. They also feature an always-on USB header that continuously pushes power, regardless of which state the PC is in.

The units are expected to be priced from $79 to $109, though no official MSRPs have been released yet.

    I had a GX 450w some time ago. It worked good enough to power pretty low end system. Overclocked, stable and for a long time (athlon ii x3, 2 hdd and nice hd 6850). It is even working in another computer that gave to a friend. I guess that theses guys will just do the job, way better than the Extreme series.... which are crap.

    Prices will have to be better on the "street" for these to sell. When Corsair has comparable PSU's around $40-60 street (sometimes less w/MIR's) these will have to be similar to get any traction.

    with all other good choices... CM would be at the bottom of my list.

    dont get me wrong, i have a CM sentinel mouse, CM Sirus headset, had CM690 case. But psu? sorry, they have to re-stablish the CM brand for that first

    Iirc, the GX-450 was the only GX that reviewed well; the others were not good at all. Unless these are made by Seasonic, I will assume they are poor, unless / until they receive favorable competent technical reviews.
