I decided to build a new computer partially to learn more hands on and then I decided to build a rig that has some serious power needs. My question is not how much watts do I need but instead, which brand is more reputable. If anyone replies I need a power supply with between 1000 watts to 1200 watts. If you want to see what I am building I can give you specs.

Please let us know what your build is if you want specific advice. As far as brands go XFX, Seasonic, Antec HCG, EVGA Supernova G2, Corsair Hx and Tx are very good. Check out the list on this thread...http://www.tomshardware.co.uk/answers/id-1804779/power-...

I am building starting with the mother board which is a m5a99fx pro r2.0 with 16 gb of random access memory along with an hd 7850 graphics card. The cpu is an amd 8 core 8320. I just want to know who makes good power supplies so that i do not make a bad choice. I also would like to add that I may make many gamers mad by telling you that this build is only for my personal pc and I do not play games. my son plays minecraft and that is all. I will benchmark this build and if you want to know if it is a good board and processor, I will let you know. I almost forgot, the graphics card is an hd 7850 if that helps and the case is a thor recommended by toms hardware. Holy crap it is big!

A decent 550-600W power supply will be more than adequate. Have a look at the 550W XFX core and TS models or the Antec HCG 620W or a 620 Seasonic (I think G series but they don't sell that many SeaSonic's in the UK so I not 100% au fait with them!)

These are good...

Are you kidding? With a 7850? You need 500W and 600W is nice! What site are you using to work out 1000W?!

higher end motherboard, processor, ram keyboard and mouse 150 watts. fans 5 watts a piece. sata hard drive 35 watts. dvd- read write 35 watts. high end graphics video card about 150- 300 watts. pcie x16 card 100 watts. I know what my power needs are if any one can help I am looking for a recommendation on a power supply. I do not know why some are rated platinum, gold and bronze. I just would like a solid recommendation from someone who has dealt extensively with power supplies.

Well I gave you three so I'm off to bed (it's almost 2am here) hope you choose one from my list or someone else comes to help you. You really don't need more than 600W unless you're going to SLI in the future. Why don't you have a look at systems other people have built in the past on these forums and take your cues from what they used?

For the suggestion of your build a 550W-650W 80 bronze will be fine. A quality 550W power supply will be fine with any single gpu build.
XFX 650:

The rating of bronze, gold and platinum is the efficiency of converting AC power to DC power. 80+ Bronze should be the minimum.

If you plan to SLI or crossfire very high end gpu like R9 290X crossfire then the justification of getting a 850W or more is acceptable if overclocking.

Actually, I calculated the wattage based on what I learned in college.

Here a review of the 7850: http://www.guru3d.com/articles_pages/msi_radeon_hd_7850...

They got 254W in terms of power for the whole system. The card actually draws 106W roughly.

When you select a power supply, you should pick one that can handle the total combined wattage of your system and also it should be rated around 30% higher than what your system will use (Andrews, J. (2010) CompTIA A+ Guide to Managing and Maintaining your PC. Boston, MA: Course Technology).

But there is no need for a 1000W power supply for that build you listed. A 550-650W will be fine, no doubt. It is not just the wattage you look for. It is the Amps on the 12V rails as well. You want at least 40 AMps.
Regardless of what the book said, a quality 550W-650W power supply is enough for any single gpu build.

I agree exactly. When you look at similar builds you should see that the power supplies used are in the region of 600w. If this really concerns you then get a 700-750 watt model from the ranges I already suggested, its up to you at the end of the day what you go for. All we are trying to do is help to keep your build balanced and reasonably priced. If you plan on overclocking your processor AND adding another 7850 in crossfire then a psu of 850-1000w would be sensible. Like the previous poster said, the amperage of the 12v rail(s) is just as important to consider.
