MSI GTX 660 Ti Power Edition

Product Number: N660 Ti PE 2GD5/OC
Warranty: 3 Years

It seems like every generation has its Power Edition or Twin Frozr-branded MSI card. Weíve seen the HD 6950 PE, and HD 7950 Twin Frozr and next week the GTX 670 Power Edition will hit our pages as well. MSIís all-out assault has hit the GTX 660 Ti market right away with a new Power Edition card which incorporates upgraded PWM components, the famous Twin Frozr IV heatsink and triple overvoltage capabilities.

MSI also backs up their cards with a three year warranty. Now, this many not seem like much to the average consumer but it is part for the course in the GPU market and MSI has the advantage of localized RMA facilities in Canada and the United States. This should hopefully facilitate the handling of any problem-plagued cards.

The Twin Frozr IV heatsink found on the Power Edition uses the same design as the one found on MSIís Lightning series so it certainly has cooling capacity to spare. It uses a quartet of large heatpipes, an extensive aluminum fin array, a secondary heatsink for the PWM and two large fans for quiet yet efficient operation.

The fans are programmed to counter rotate at high speeds for about 30 seconds at system startup in order to remove any dust thatís been accumulating on the heatsink fins. This ďdust removal technologyĒ is supposed to keep the Twin Frozr IV heatsink operating at peak thermal efficiency so temperatures donít deviate over the Power Editionís lifetime.

All of the components listed above have similar goals: increase card longevity, optimize overclocking results and lower heat production. Unfortunately, we canít conclusively test any of these claims here but the Power Edition incorporates all of them so overclocking stability should be great.

MSI has been talking about Military Class III components for some time now and most of their high end graphics cards ship with a certificate proclaiming this status. Military Class III is simply a marketing term that means MSI chooses the highest quality components, all of which are MIL-STD-810G certified. While this may not mean all that much for your run of the mill layman, it should (hopefully) lead to increase ASIC longevity.

As with all of the other cards in this roundup, MSI has decided to stick with the reference connector layout on both the power input and video output sides.
