The power supply is finished in a very attractive black paint. It does attract fingerprints fairly easily however as it isn't a dull matt finish. The large 120mm fan takes centerstage at the top of the chassis, and strangely enough our review sample didn't have Cooler Master branding on it.
The rear of the PSU is fully vented to help with airflow. To the right is a power connector and a switch for easy access.
The same graffiti style box artwork features on the side of the chassis – this is a sticker, not painted onto the chassis itself.
The GX650 isn't a modular design so the cables all emerge from the front of the unit and are shipped with a thin cable tie around them.
| Cable | Amount |
| MB 20+4 pin | x1 (500mm) |
| CPU 4+4 pin | x1 (600mm) |
| PCI E 8 pin (6 pin +2) | x2 (500mm each) |
| Sata power connectors | x6 (2 cables) (500mm + 100mm each) |
| Peripheral 4 pin (molex) | x6 (2 cables) (500mm + 100mm each) |
| Floppy connector | x1 |
The GX650 has two PCI E 6 pin + 2 connectors, so if your system build needs more (SLI or Crossfire) then you will need to move to the higher end model, the GX750, which is supplied with 4 of these cables.

The GX650 has a single +12V output which is rated to 52A under full load.
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.
