Hello,
I am looking into building a pc because my current one has a very old pentium processor which I could buy for 5 bucks as well as 1.25 GBs of RAM(upgraded) and integrated graphics.
I am looking at these parts and need a PSU that would fit them, anything under 85$ is fine.
Planned Parts:
AMD Vishera FX-6300 3.5 Ghz and 6 cores
8Gb of any RAM from a reputable source
Radeon HD 7770 Ghz edition
GIGABYTE GA-970A-D3 Atx MoBo
Chronos Enhanced Muskin 90Gb SSD
500Gb HDD 7200 Rpm probably WD
Case I'm not particularly bothered by, will probably go with a Coolermaster.
Sorry if Ive forgotten ay parts, please say.
Any other comments are appreciated.
Thank You

For a system using a single Radeon HD 7770 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 23 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.

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) will 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.

You may find power supplies on the market that supply more than enough Wattage to run the system. However, some of them lack Sufficient Amperage capacity on the critical +12 Volt rail, which is necessary to properly power the critical components in the system (i.e. CPU and GPUs). This is the reason why graphics card manufacturers may overstate the power supply wattage, usually by at least 50 Watts, in an attempt to take into account some of those power supplies that have the weaker +12 Volt rail(s).

The Seasonic S12II-430 Bronze 430W Power Supply (SS-430GB), with its maximum combined +12 Volt continuous current rating of 30 Amps and with one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single Radeon HD 7770 GHz Edition graphics card.

The Seasonic S12II-520 Bronze 520W Power Supply (SS-520GB), with its maximum combined +12 Volt continuous current rating of 40 Amps and with one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is way more than sufficient to power your system configuration with a single Radeon HD 7770 GHz Edition graphics card.

Cases are more of a personal preference item.

I haven't bought a cheap case so I'm not the one to ask. My last PC case I purchased runs in the $300 range since its made of heavy gauge aluminum alloy.
