The Power Supply

The AcBel iPower 90m is marketed as a 80 plus gold rated efficiency power supply unit but the 90 Plus efficiency emblem on the fan grill is telling us that it can deliver more than what it is marketed to be.  

At the side of the PSU you'll find the AcBel branding and the model name.

At the other side of the PSU we can find the power output details listed in a table. The AcBel iPower 90m 700W is capable of delivering 672W watts via the +12V rails, which is plenty much enough for most high-end graphics card, i.e: AMD R9 290X, AMD R9 280X, Nvidia GeForce GTX Titan X, Nvidia GeForce GTX 980.

Just like any other semi-modular power supply unit we've seen, the AcBel iPower 90m has the indispensable 24-pin and 4+4pin power connector attached to unit. The 4-pin molex, SATA and PCIe power connector modular cables is made optional for better cable management.

The modular cable slot is also placed vertically to make cable management easier and reduce potential damage to the cables by bending side ways.

Testing & Conclusion
As Tech Critter do not own any industrial grade load tester to perform intensive tests on the power supplies on hand, we will be performing tests from the end user's angle. 

We've mounted the AcBel iPower 90m 700W on our Vector Bench Case and have gone through numerous tests which involves stress test and overclocking various hardwares i.e: Intel i7 4770K / 4790K / 5960X, AMD R9 280X, Nvidia GTX Titan X, Nvidia GTX 980 - glad to report that no issues is encountered, it survived various stress test with no coil whine issue found throughout the testing period. 

Another test conducted is the Haswell ready low power state test. Instead of testing on the power supply on full load, we take its ability to handle the low power state with C6/C7 states enabled in the BIOS configuration. We've tried to put our system to standby mode / hibernate / sleep mode and resume the system from these state, glad to report that there's no stability and compatibility issue as well.

Overall, the AcBel iPower 90m 700W deserves a recommended badge from!
