Ok I need a good cheap power supply for my computer build I prefer modular because I have a mid tower and I will be keeping this psu for the next generation as well. So it should be in the 100-200 dollar range. WEBSITE I WILL BE PURCHASING FROM - http://www.pccasegear.com/ PLEASE NO NEWEGG OR AMAZON ! Since I live in australia.

PARTS:
CPU - FX 8350
GPU - AMD 7950 Sapphire OC
RAM - 16GB kit 1866
MOBO - Gigabyte GA-990FXA-UD3
HDD - WD Black 1tb + 500GB blue
COOLER - H100i
DVD drive + 2x 120mm fans + 2 140mm Fans

I also will be overclocking my cpu and gpu but not intensively.

Thanks.

Online power supply calculators are NOT reliable, and even if they are, they give you a number that's significantly greater than what you actually need, because they presume that you're buying a very bad quality power supply that won't be able to provide even as much power as it's rated for.

Under load, your processor will draw 200w - call it 250 to account for overclocking. Your graphics card will draw about 150, and won't be able to draw much more with overclocking. That's 400 right there - add 150 for everything else plus overhead, and yes, a good quality 550w power supply will be more than enough for your needs.

For a system using a single Sapphire Radeon HD 7950 OC graphics card a minimum of a 500 Watt or greater system power supply is recommended. The power supply should also have a maximum combined +12 Volt continuous current rating of 34 Amps or greater and have at least one 6-pin & one 8-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) 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.

The Antec High Current Gamer 620W Modular (HCG-620M), with its maximum combined +12 Volt continuous current rating of 48 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is way more than sufficient to power your system configuration with a single Sapphire Radeon HD 7950 OC graphics card.

The Corsair HX-650 V2 80 PLUS Gold (SKU# 75-001217 / CP-9020030), with its maximum combined +12 Volt continuous current rating of 54 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is way more than sufficient to power your system configuration with a single Sapphire Radeon HD 7950 OC graphics card.

The Seasonic M12II Bronze 620W (SS-620GM), with its maximum combined +12 Volt continuous current rating of 48 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 Sapphire Radeon HD 7950 OC graphics card.

Thanks a lot for the reply What do you reckon about the silverstone strider series PSU's ? They are cheap and fully modular but if you insist I might spend a couple bucks more for the Seasonic X-660. Thanks again !

They aren't as good quality, and fully modular vs semi modular really doesn't matter - you're always going to need the CPU power connector.

That being said, if you want to save the money, go with the silverstone - which might be a good option. If you want to have a power supply that'll last you for freaking ever, go with the X-650. (they have it named wrong.)

Here are a couple reviews of it so you can see I mean it when I say it's basically one of the best ones out there.

It's a choice you shouldn't regret; it's built to be very solid and very, very reliable.
