GTX 660 for 1080p gaming

The MSI N660 GAMING 2G D5-OC is a GeForce GTX 660 graphics card built for 1080p gaming. It ships with 2GB of GDDR5 memory on a 192bit interface and connects through a PCI Express 3.0 16X slot. A single 6pin power connector feeds the board.

Sustained load behaviour

Under sustained load the card runs at its rated 6008MHz memory frequency and maintains the factory overclock. The Twin Frozr cooler dissipates heat across extended sessions so clocks remain stable rather than throttling after a short burst. This helps deliver consistent frame rates in longer play sessions.

Pre-purchase checks

Verify that your motherboard provides a PCI Express 3.0 16X slot and that the power supply includes a 6pin connector with enough headroom for the whole system. Confirm the case has enough length and height clearance for a dual-slot design. Ensure the display can accept a 2560×1600 signal over the available outputs.

Questions about this item

How much heat and noise does the GTX 660 produce when running all day at 6008MHz memory frequency?

The card uses a single 6-pin power connector, indicating a moderate thermal envelope that the Twin Frozr cooler handles with low fan speeds under sustained load.

What power supply connector must my system already have for this PCI Express 3.0 16X card to work?

Your power supply needs one free 6-pin PCIe power connector; the card draws its auxiliary power exclusively through that interface.

Will this 192-bit GDDR5 card work alongside an older motherboard that only supports PCI Express 2.0 slots?

Yes, the PCI Express 3.0 16X interface is backward compatible with 2.0 slots, so the GTX 660 will function at the older generation's bandwidth.
