is coolermaster any good? - Page 2

Looks like you're right Shub and I stand corrected-

taken from HardOCP-
"Paul's Thoughts:

The Cooler Master GX 650W is the first Cooler Master power supply we have seen in a long time, and unfortunately it did not exactly leave me wanting more. Really it left me wanting some mouthwash to get this bad taste out of my mouth. The sad part is this unit is actually one I see a lot in retail and usually the price is over $100 (looking at you Microcenter) so when the opportunity arose to review this unit, I thought we might be on to something. A $100, 650W power supply can't be all bad right? Well I guess this unit isn't all bad but there were so many things about this unit that just scream "polished turd" in a box that it makes it kind of hard to see those things. The GX 650W at room temperature is possibly an ok unit barring the DC Output Quality. In the real world however, his unit is just simply half baked and it does nothing to help Cooler Master's brand in the power supply department. Why this product was launched is simply beyond me. Sure I can see segmenting your product with some different temperature ratings as the ATX12v specification does not dictate at what temperature the unit must function, but the ripple/noise values are fixed in the specification so there is no excuse for that failure from this unit today.


The Bottom Line

The Cooler Master GX 650W is a mediocre power supply for couple of years ago, and an outright failure today. The Build Quality of the unit is nothing to write home about (unless it is a warning), the topology is old and outdated, and the exterior is flash over substance. Coupled with this we have mediocre voltage, poor by today's standards efficiency, and out of specification DC Output Quality. One upping this poor showing is that fact that the unit was completely unable to complete our load tests at 100v AC input. That makes the GX 650W not just a failure by our standards, but rather a double failure and an ugly one at that. Making matters worse is the fact that this unit is priced at up to $100 in retail and $70 online. (Users can pick up the much better Seasonic M12II-620Bronze from Amazon with Free Prime Shipping for $98.29). As it stands, there really is not anyone that this unit would be a good fit for that we can think of, and certainly not for its intended crowd of "gamers." Cooler Master should be ashamed and owes all gamers and hardware enthusiasts an apology."

It may be worth it to ship it back and pay the restocking fee... If you're really broke, then just refuse the entire package when it arrives, you'll get all of your cash back within a week or so, then just make the order again, with a different psu.

Although I still feel like you'd probably still be fine with the gx 650, there is a (admittedly small) chance that it could fail and take out some other component/s with it.

In Cooler Master's defense: they recently took steps to refresh the GX lineup, and the newer units are significantly better. They added a brand new 450W member to the series, and replaced the 550, 650 and 750W versions as well. All are from the same OEM (Enhance) and I'll take Enhance over the old OEM (Seventeam) anytime.
Unfortunately I haven't really seen the new versions up for sale.
Older version: RS-650-ACAA-E3 / 80 Plus rated
Newer version: RS-650-ACAA-D3 / 80 Plus Bronze rated

thats exactly what I'm afraid of, I did in fact order the older version (RS650-ACAAE3-US) I guess the easiest way to do it would be to send the GX650w for a return and go to best buy and pick up a corsair 650w on my credit card, although I hate owing money to the bank, I guess its better than fried components
