hello, i recently build a pc, it has in it a amd phenom II x4 BE 955 on a biostar TA880GB+ motherboard with built in graphics AMD880G (RadeonHD4250) im wondering if an upgrade to a HIS Radeon 6870 is suficiant enough for gaming. im looking to spend around $200$ any sugestions?
A Radeon HD 6870 has a maximum load board power of 151 Watts. This means the graphics card itself will draw up to 12.6 Amps from the power supply unit's +12 Volt rails.
For a single Radeon HD 6870 graphics card system AMD recommends a power supply with 500 Watts or greater with a minimum +12 Volt current rating of 24 Amps and with at least two 6-pin PCI Express supplementary power connectors.
Is your power supply unit's combined +12 Volt rails current rating at least 24 Amps or greater?
A GeForce GTX 560 Ti requires at least 30 Amps or greater the power supply unit's combined +12 Volt rails.
