A Detailed Look (Cont’d)
The front panel incorporates sixteen modular cable connectors, all nicely labeled. The six 6-pin connectors on the left are for the peripheral cables and there are eight 8-pin connectors on the right for PCI-E and extra CPU cables. The 24-pin mobo cable uses two connectors. The 4-pin Comm Port connector is where the cable from the Corsair Link USB dongle cable plugs in.
Also note the Self-Test push-button and LED indicator in the upper left corner.
The Corsair AX1200i Digital power supply comes with a large assortment of all modular cables and connectors. Some of the cables are covered with braided plastic mesh sleeving while others are a flat ribbon-style cable.
The Corsair AX1200i package includes six PCI-E connector cables for multiple, high-end graphic card support. Corsair uses the 6+2-pin configuration for added flexibility.
ZVS / ZCS Technology
The AX1200i Digital PSU utilizes Zero Voltage Switching / Zero Current Switching technology to maximize energy efficiency and performance. Switching mode computer power supplies operate by rapidly switching the primary power transistors on and off with the output voltage being regulated by the associated switching duty cycle. Conventional power supplies traditionally use "hard-switching", whereby the current and voltage are not switched at 0V and 0A. This results in switching power losses and increased EMI.

The Corsair AX1200i utilizes ZVS / ZCS technology to switch at near 0V and 0A, which ensures there are minimal switching losses. This helps maximize efficiency and further reduces waste heat.
Lee and or PCPER I am a bit
Lee and or PCPER I am a bit confused about the PSU test bench as described in this article. ‘Up to 2000W’ but also mention real-world test.
Which tests are you using the PC-based load for and which tests are you using simulated loads for ?
Or are you using both?
Many of the top review sites are using the imported ATX tester or home brew resistor grids which is not a ‘real world test’ (but a simulated one) and I am interested as to how you are pulling off a real world PSU test
Additionally, testing in open air versus mounted in a warm PC chassis, typically pushed against a wall or under a desk.
Thanks.
The PCPerspective PSU test
The PCPerspective PSU test bench uses a combination of six Progammable DC loads and up to three different banks of precision load resistors to create the various loads (up to 2,000W max). The real-world testing is stated because we mount each PSU in a modified case and recirculate some of the warm exhaust air back to the inlet to "simulate" real-world operating conditions. The loads are not real-world (actually much more precise and programmable) but the test environment is, temps gradually increase as the load increases just like in a real PC – the best of both worlds.
Hi I’m Carlos , I have a
Hi I’m Carlos , I have a Corsair AX1200.
ME DAMAGE IS A POWER SUPPLY CAPACITOR , THE POWER SUPPLY NOT OPERATE MORE. I’M FROM ARGETINA AND I CAN NOT GET THE CAPACITOR (2.2uf 450V) FROM THE +5VSB PCB. HOW CAN I FIX THE `POWER SUPPLY???
There is a led on the dongle
There is a led on the dongle that flashes between red and green, what is its meaning?
Thanks
