For a system using a single AMD reference design Radeon HD 7870 GHz Edition graphics card AMD specifies a minimum of a 500 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 28 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors.
Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.
Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.
The Antec Basiq Series 430W (BP430) power supply unit, with its maximum combined +12 Volt continuous current rating of 32 Amps and with one 6-pin PCI Express supplementary power connector, is electrically sufficient to power your system configuration with a single Radeon HD 7870 GHz Edition graphics card but is deficient by one 6-pin PCI Express supplementary power connector.

U should always have a PSU that can run ur system and has extra 100W to spare. For example: System uses 400W= U must have a power supply of 550W-600W.
If u have enough power and good branded PSU, u will know that ur safe.
If I were u I would buy this one:

Edit: Get a XFX Core edition (ProSeries) 550W power supply unit. I have it myself and it rocks!

With the Antec 430W dual rail PSU's I wouldn't recommend the use of the dual 4-pin Molex to 6-pin PCI-E adapter cable because some of the Radeon HD 7870 GHz Edition cards can draw enough power to trigger the Over Current Protection circuit. One of the +12V rails is dedicated strictly to power the CPU and the other +12V rail is used to power the remainder of the system (i.e. motherboard, graphics card, SSD(s), hard disk drive(s), optical drive(s), cooling fans, etc.).
Your best bet is to get a power supply unit that actually has the appropriate number of PCI Express supplementary power connectors.
