DC Outputs and Quality








We see very little voltage drop on the rails, which is very good. All of the rails are within 2% to 2.5% of regulation, starting slightly higher than the target voltage and dropping slightly below target at higher loads. Ripple on the 12V rails is also exceptionally good, measuring at most 8mV. Lower voltage rails also perform decently, though not quite as good, measuring up to 21mV. The ability of this power supply to deliver the required wattage with little voltage drop even at higher loads leaves us with a good impression.

    In the past 12 months I've bought 2 Coolermaster PSU and 1 case, all with rebates making close enough to free. They were all an excellent compromise for the price and all rebate checks were received.

    Yes you may see lots of people that didn't get a rebate check but remember that when something normally costing about $40-50, not $25, ends up around $0 to $10 after a rebate, you have a very large # of people who take advantage of it so even 100 reports of not getting a rebate check may be a small % of total buyers.

    I happen to be typing on a system that has a 600W Coolermaster Extremepower PSU in it, while it isn't very old yet at about 8 months, it has done fine thus far with overclocked CPU, video, 4 hard drives. Granted it's only peaking at roughly 300W consumption but a little common sense is good in this area, one doesn't buy a $50 PSU then expect to get 600W out of it long term.

    I really appreciate the test articles and the time spent on the testing setup. Thanks for the heads up about the 80plus silver certification/marketing ploy. I now see that this is not the PSU for my application.
