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.
hard to complain with that pricing structure. I just hate non modular power supplies now. they make a system build so much more messy.
Yeah, good budget model for sure. I agree with modular comments however. dont think id ever buy a new non modular PSU. I hate routing unneeded cables.
They seem to be releasing a lot of products in recent months.
Great pricing for a quality product. never owned a cooler master product before, well not a PSU anyway
That sticker on the side is ugly IMO, but the design seems very good all round. I have to upgrade soon, but I wish they would have made this in a modular design. i learned the hard way
Hard OCP failed this power supply and said coolermaster should be ashamed
isnt that the older model though? they had a previous version of this out, but it wasnt bronze certified and it was an older design too.
It was the RS650-ACAAE3. what’s this one’s part number?
I just looked on EBuyer and they are still selling the same part as this one, not a new part

Thats the older model, its a different internal design and isnt 80 plus bronze rated either.
The GXs that got bad reviews were built by Seventeam, it looks like, based on this review, that the Enhance built ones will be better.
I think the greatest problem with this product is going to be customer confusion. Just remember to look out for D3 in the model number, otherwise don’t get it.
@Zardon, thank you for including cable length measurements.
@Dan, i don’t think this batch is made from Enhance. cuz what i read on hardocp is same manufactured with this so called “Enhance” oem.

both of the UL code is E320127, its mean OEM by Acbel? i am so confused, cuz last time i remembered the previous batch is oem by seventeam, it should be E141400.

cooler master really try to make a fool around us?
Here is another review of the newer Cooler Master GX650 Bronze:
http://www.techpowerup.com/reviews/CoolerMaster/GX650W_Bronze/
he confirms that the OEM of the new GX series is Enhance.
That HardOCP image is from the review of the Seventeam built unit, and published in 2010. These Enhance ones are very/much more recent.
As for that Toms link, it is probably only useful as a rough guide, not something to swear by; its already out of date. And IMO, has an over-reliance on UL numbers.
It’s been awhile since UL numbers were a good way of finding out the OEM for power supplies.
