Refurbished RTX 3070 for 1440p gaming

This refurbished MSI Ventus GeForce RTX 3070 graphics card targets players who want high-frame-rate 1440p performance. The GPU delivers 5888 CUDA cores and a 1755 MHz boost clock. 8 GB of GDDR6 memory on a 256-bit bus provides sufficient bandwidth for modern titles. A triple-fan thermal design with a graphene backplate keeps temperatures controlled.

Suits 1440p builds; avoid for 4K ultra

The card suits builders with a 650 W power supply and two 8-pin connectors who game at 1440p or high-refresh 1080p. It supports four simultaneous displays via HDMI 2.1 and three DisplayPort 1.4a outputs. VR-ready certification covers headset use. Users targeting 4K ultra settings or workloads needing more than 8 GB VRAM should look at higher-tier models.

8 GB GDDR6 256-bit decides fit

The single specification that decides fit is the 8 GB GDDR6 frame buffer on a 256-bit interface. This capacity handles current 1440p textures comfortably but can limit 4K ultra texture packs and some professional rendering workloads. If your typical resolution and texture settings stay within 8 GB, the RTX 3070 Ventus 3X OC remains a strong match.

Questions about this item

Does the card ship with power cables or adapters, or do I need to source two 8-pin connectors separately?

The card requires two 8-pin power connectors. Power cables are not included; they must come from your power supply.

Is the 1755 MHz boost clock the only speed difference between this Ventus 3X OC and a non-OC model?

Yes, the factory overclock raises the boost clock to 1755 MHz. All other specifications — 5888 CUDA cores, 8 GB GDDR6 at 14 Gbps on a 256-bit bus — remain identical.

Will a 650 W power supply actually handle the 220 W board power plus the rest of my system?

The manufacturer recommends a 650 W PSU for the 220 W TDP. That figure covers the card itself; ensure your CPU and other components leave enough headroom within the same unit.
