Hey everyone I was wondering if this psu would power a 6850 or 6870 in a new build.

It seems like a great psu for the price but I want to make sure my computer won't blow up if I get it.

Depends what the rest of the system looks like, but overall yes it will work fine with those cards.

For a system using a single Radeon HD 6870 graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 30 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors.

For a system using a single Radeon HD 6850 graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 26 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.

The Corsair Builder Series CX430 V2 (CMPSU-430CXV2), with its maximum +12 Volt continuous current rating of 28 Amps and with only one 6-pin PCI Express supplementary power connector, is only sufficient for a system using a single Radeon HD 6850.

You'll need at least the Corsair Builder Series CX500 V2 (CMPSU-500CXV2), with its maximum +12 Volt continuous current rating of 34 Amps and with two (6+2)-pin PCI Express supplementary power connectors, for a system using a single Radeon HD 6870.
