hi,i am trying to choose between multiple PSUs but can't choose the required Wattage for overclocking my gtx 970 and i5-devil's canyon my current psu is cooler master extreme II 525w and i am comparing between these two:

XFX TS Series 650W 80 Plus Bronze PSU

CORSAIR CX600M 600w 80 PLUS Bronze Modular PSU

thank you.

No, the Cooler Master Extreme series units are crap and generally can barely do 50-75% of their rated capacity.

Extreme Power Plus 600w review: http://www.hardwaresecrets.com/cooler-master-extreme-power-plus-600-w-power-supply-review/9/


The bottom line, and this is well known to ANYBODY who knows a thimbleful about power supplies, is to avoid Cooler Master power supplies, even more vehemently than you do Corsair as they are well known to use liar labels and contract terrible designs from whomever builds their units. They may, and I say MAY with the greatest amount of levity, have a couple of decent units, but I for one would NEVER, EVER, purchase or recommend a Cooler Master PSU. Not even if I didn't like you.

The 80plus rating has nothing to do with that XFX units quality. It's a quality unit because it's a Seasonic built unit. The higher efficiency rating is nice, but would never be a selling point for me. I'd rather have a high quality unit with NO 80plus rating than a cheap unit with a Platinum rating.

Aside from the fact that I see plenty of them in various states of failure throughout the forum, they also lack heatsinks on the 12v MOSFETs and use lower quality Ltec and Taicon capacitors on the secondary side. They test well at first, just like the CX units, but in six months to a year, tend to have similar failures to those units due to the weak capacitors.

As taken from the HardOCP review:

lack of heatsink on the 12v MOSFETs and the lower quality Ltec and Taicon capacitors on the secondary side, including those on the modular interface which are really going to be starved for airflow (not a good plan). The primary side capacitor is still a Nippon Chemi-con but that isn’t saying much.

Overall, the Corsair RM750 was an across the board disappointment as it failed to complete our load testing today. However, if we ignore the fact that the unit failed and look at the tests it did complete we still don’t see a great power supply. For instance, in the voltage regulation, the 12v rail saw a total drop of 0.18v and the 5v rail saw a total drop of 0.11v during our testing.

Moving over to the Transient Load Testing results for the RM750, we find that the results are passing for the test that the unit would complete. (Which was a single test only.)

The DC Output Quality of the Corsair RM750 is easily passing, and good, for the tests it would complete. Overall, the 12v rail peaked at ~40mV of ripple/noise while the 5v rail peaked at ~20mV and the 3.3v rail peaked at ~15mV. Unfortunately, these relative results put this unit in the same boat as we saw in our load tests. That is to say, it trails the XFX Black Edition 750W, XFX Core Edition 750W, and the Corsair TX750 V2 while only being comparable to the TX750M. Some days passing is just that, passing, and not really excelling. Today is one of those days.

The Corsair RM750 today is one of the more frustrating products we have had in to review in some time for a number of reasons. Starting at the top, the unit was delayed multiple times to fix issues and then at the end of the day the unit is still broken! Then there is the fact that IT IS broken all by itself, never what you want to see especially when you pay a premium for a Corsair branded unit. On that note, when paying a premium for a unit you generally like to see at least somewhere in the upper quartile components and, while not total trash, Taicon and Ltec are not there. This goes double for when we are looking at a unit that is going to be baking inside since the fan controller has been tuned so aggressively for quiet operation that it barely ever runs even if apparently it should. Finally, it isn’t even better than previous "lower tier" Corsair products we reviewed some time ago. Apparently Corsair was betting big on this game of Craps and came up snake eyes.

Add the number of failures I see in person on these units, on the forums and in this and other reviews together, and I say it's not worth buying when you can get a very good unit for a similar price.

good point. Yeah quality of components is often overlooked when the PSU initially tests well in a review. I wont buy anything that doesnt use good quality Japanese capacitors. And for the sake of costing the manufacturer a few cents vs their reputation.
