ECS Elitegroup P55H-AK Review



The P55H-AK motherboard has just about everything you could possible want, or need, in a P55 based board. From the tri-fire SLI/CF to the multiple USB 3.0, SATA 3 and eSATA 6.0 Gb/s ports. The addition of the NVIDIA NF200 switch along with the multiple NEC D720200F1 chips and the PLX PEX8608 chip create a motherboard with the capability of sustained performance when using the high speed interfaces and multiple PCI-E slots that are available on this board. This is one of the most feature rich P55 motherboards available today at any price.

The performance of the P55H-AK was right on par with the ASUS and Gigabyte we put it up against. That is saying a lot for a company that has just started trying to compete with the likes of ASUS, Gigabyte, MSI, EVGA, etc. in the higher-end enthusiast sector of motherboard manufacturers. They have a quality product here that should really help them compete in this sector.

The only negative I could find on this board was the dual-pipe heat sinks on the MOSFETs and NF200 did tend to get really hot. I removed all the heat sinks off the motherboard and found out that the culprit generating the vast majority of the heat was in fact the NF200 chip. This did not in any way hinder the overclocking I did with this board but it would have been nice to have a better cooling solution on the NF200 alone versus all tied together with the MOSFET coolers. The addition of a fan or a case with very good air flow over this area should keep this in check though.



  • Good overclocking ability
  • Tri-SLI/CF support
  • USB 3.0, SATA 3 and eSATA 6 Gb/s supported by multiple NEC and PLX chips
  • 15µ gold coating on memory and CPU contacts
  • 14 Phase (12+2) PWM
  • On-board power and reset buttons



  • Dual heat-pipe sinks did get very hot
