PSU Testing Methodology
Establishing an accurate load is critical to testing and evaluating a PC power supply. PCPerspective’s power supply test bench can place a precise DC load on the PSU under test. Each power supply is tested under controlled, real-world conditions up to its maximum rated load (at 40ºC), using both 115 VAC and 240 VAC line voltage. Our current suite of tests includes:
• DC Load Regulation
• AC Ripple and Noise
• Efficiency
• Differential Temperature
• Noise
The Corsair AX1500i Digital power supply was evaluated on both features and performance. A full range of equipment was used to test the power supply under controlled load conditions.
• (2) CSI3710A Programmable DC load (+3.3V and +5V outputs)
• (4) CSI3711A Programmable DC load (+12V)
• (3) 218W Precision resistor load bank (+12V)
• Switchable precision resistor load bank (-12V and +5VSB)
• Agilent 34401A digital multimeter (Accuracy ±0.0035% vDC)
• Extech 380803 Power Analyzer (Accuracy ±0.5% of full scale)
• DS1M12 "StingRay" digital oscilloscope (20M S/s with 12 Bit ADC)
• Powerstat Variable Autotransformer, 1.4 KVA, 0-140 VAC
• Extech Model 407738 digital sound level meter (Accuracy ±1.5 dB)
The following cables/connectors were used to connect the AX1500i to the PCPerspective power supply test equipment.
• (1) 20+4 pin ATX
• (2) 8-pin EPS/ATX12V
• (9) 6-pin PCI-E
• (2) SATA
• (2) Molex

• Corsair Link not supported in Win XP
lol really minor at this time…
indeed don’t think that someone buys this beast to run it on Win Xp… would be unbelievable 😀
Agreed… very minor!
I
Agreed… very minor!
I almost didn't include it but the issue did come up during my testing as I initially tried to install Corsair Link on one of my old CPU cooler test beds that happens to be sitting next to the PSU test equipment (have retained Win XP environment for consistency over the years). Pretty good PSU if that was the only "weakness" that came up during testing.
Any chance you will test the
Any chance you will test the 2 295X2’s on this?
Already tested in this
Already tested in this video.

More details to come.
Sorry, we had to send back
Sorry, we had to send back the second R9 295X2 card before the AX1500i arrived to me. :/
Oh ya I remember you
Oh ya I remember you mentioning that. Well maybe someday in the future!
This is the first time I have
This is the first time I have heard of ATX 12V 2.4. Whats new? I am considering buying a new PSU now I am interested to know.
Good question: according to
Good question: according to our technical expert at Corsair… "The only difference between ATX12V 2.3 and 2.4, AFAIK, is that the 2.4 has the Haswell testing (0 load on the +12V to see if the PSU can support the C6/C7 sleep states)."
It doesn’t meets the
It doesn’t meets the efficiency requirements for 80 plus Titanium for 240v , 80 plus Titanium for 240v at 50% load mute be 96% or higher.
Hi,
I am testing Link
Hi,
I am testing Link software on my machine :
Config:
At IDLE load, PCIe A all current values are shown as ZERO,
Does this software have some threshold, above only it can sense current properly?
Following is sample data:

would this Corsair AX1500i be
would this Corsair AX1500i be enough for powering two motherboards?
I want to install in a single box Linux and Windows and would need a good graphics card for a 4K monitor
