[section_title title=Performance]Performance
Since we don’t currently have access to an ATE load tester, a multi-meter is used to show each of the power supplies performance on the 3.3v, 5v and 12v rails. Although we can’t do full load tests, we can provide relative information regarding variance and fluctuation of current and ripple on the rails which is integral and indicative of quality in a power supply.
To perform the above tests, the methodology will be as follows:
Test Setup
I7 4770k @ 4.8GHz
Gigabyte Z97Â SOC Force
1 x Zotac GTX 780
8GB (2x4GB)Â TeamGroup Vulcan 8GB (2x4GB) 2400MHz
1 x 250GB Samsung 840 EVO
Super Flower Leadex GOLD 650watt
Voltages will be monitored via a multi-meter and the AC power draw will be monitored via a power monitor when drew from the wall. For the idle test, the system will be simply booted up and let to run into windows and after 5 minutes when the power draw has leveled out, the readings will be taken.
To load and apply power to the power supply, a combination of IBT and Furmark will be run to put as much strain on the power supply as possible. After 10 minutes the readings will be taken and to ensure maximum strain, the CPU will be overclocked to 4.5GHz. Depending on the power of the power supply, multiple graphics cards could be used in line with how comfortable I feel the power supply will cope with such load.
ATX themselves specify that a fluctuation and variable of 5% is acceptable so to number crunch it means that:
3.3V = 3.135V-3.465V is acceptable
5V = 4.75V-5.25V is acceptable
12V = 11.4V – 12.6V is acceptable.
Any readings outside of these figures will be an automatic fail.
Total idle power draw =126 w which equates to just over 16.5% so it should do spot on within the efficiency states with such a low load.
Total loaded power draw =586 w which equates to just over 77% so there plenty of load to test the power suppliers efficiency. The results of the tests were as follows:
| Idle |
| 3.3V = 3.341v |
| 5V = 5.107v |
| 12V = 12.08v |
| Load |
| 3.3V = 3.362v |
| 5V = 5.081v |
| 12V = 12.111v |
As you can see, the Leadex GOLD remains well within the set guidelines and I was highly impressed with how little fluctuation there was on the multimeter I used to test. Â The 12V line performance is a particular highlight and overall, it performs brilliantly with our testing methodology.
5V = 4.75V-5.25V is acceptable
Load
5V = 5.281v
*** Not Acceptable FAIL!! =5.62% instead of 5%
Is this how your mbrilliant test mythology shows up in concrete!
Unlesss there are a logically possible typin error in there, that could and should be a possibility as the variance with 3,3 and 12v were between 1 or 2% it seems like the result should be 5,128 most likely :(after all anything between these two numbers if the psu don’t change the measurologial errorpattern of itself from the 3,3and 12v and why should when the 5is in the middle of them minimum possible answer5,122…5,143maximum possible answer if the pattern is linear and the error stays in 0,003…0,007% misses and wichis exactly: 0,0041% for 5,128 THAT IS ALMOST A MATHEMATHICAL IMPOSSIBILITY AND INT HE NAME OF GREAT LOGIC MY XEON-BRAINS HAVE STATED THAT THIS HYPOTETHIC DEFINITION IS THE ABSOLUTE TRUTH) instead of 5,281 – BEING THE WRONG NUMBER WHAT SLIPPED INTO PAPER WHILE THE 5,128 still working on in writers core i7 affected heads numeric capabilities altered mind when doing this review steps further..
How would you like to have this kind of mentalist copywriter?
This is what I call T10-Dictionary
Hello and thanks for your comment! Thanks for bringing this to my attention, I went back and checked the testing data and I have altered the results accordingly. It seems our proofreader missed this too, which is why it has gone un-noticed! Sorry for blowing your brains though 😀
