Cooler Master are using an ADDA AD1212HS-A71GL fan which is a sleeve bearing design rated to produce 85.2 cfm while emitting a maximum of 39.1 dBa.
Large heatsinks cover the whole width of the internal structure and there are sensors connected to these, which trigger the fan speed changes. This Enhance OEM product is a dual forward design and it offers a double layer EMI filter which gives extra protection from electromagnetic interference.
The design includes a mixture of 105c and 85c rated capacitors, with the two primary CE(M) capacitors are rated 85c, 270uf at 420V.
Cooler Master are using an efficient transformer design which holds power at minimal 5v standby voltage loss so that the system can return quickly when powered on or when resuming from a sleep state. This is a single +12V rail design and all the cables are fully sleeved into the chassis preventing possible long term cable fraying. The PSU offers full multiple protection – OVP/UVP/OPP/OTP/SCP.
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.
