Cooler Master set some lofty goals for the new GX650 power supply – offer a cost effective solution for the mass market while delivering solid all round performance. The new updated Enhance design achieves 80 Plus Bronze efficiency ratings in our testing and it held solid over several weeks of ‘real world' testing, including powering a high end system with an overclocked nVidia GTX580 and Intel Core i7 980X processor.
The technical analysis shows that the design is effective. There are some minor fluctuations with Cross Load Testing on the 12V+ output, but it is nothing significant or worrying. Noise suppression is also a strong point, with all rails holding well within the rated parameters. 12V+ peaked at 45 mV which is a good result.
The choice of quality ADDA 120mm fan ensures that the components all receive adequate cooling. Cooler Master have opted for a slightly aggressive fan setting within the upper 15-20% of ultimate power delivery, meaning the PSU remains audible, although it is never intrusive or annoying.
On an aesthetic level, Cooler Master have aimed for a ‘street graffiti' style box and sticker appearance, clearly to improve the cool factor with the buying public. Its superficial, but the bold yellow and orange ghetto font will stand out in a store. The unit itself is surprisingly understated with plain black paint job and black fan.
We don't have confirmed pricing just yet, but we are assured that it will be very competitively marketed in the UK (around the £55 inc vat mark).
Pros:
- Good all round performance
- looks are appealing
- capable design
- will be competitively priced.
- five year warranty gives peace of mind.
Cons:
- Non modular design means there will always be plenty of cable routing.
KitGuru says: A solid buy for an enthusiast user. Those who have a more demanding graphics card configuration should aim higher up the range.
