Currently building a media center. I'm curious if SeaSonic SS-300TFX(300W PSU) is enough to power an A10-5800k and a Radeon HD 6670.

Hi - realhardtech suggests (this is their expertise) a quality 400w(min 17a on +12v) unit
for a system with a single 6670. There is some headroom built in, but I wouldn't
recommend as low as 300w, and do suggest you consider 400-450w.

Here's a couple to consider:

http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026 nets to $35

http://www.newegg.com/Product/Product.aspx?Item=N82E16817371045 nets to $43

http://www.newegg.com/Product/Product.aspx?Item=N82E16817207018 nets to $50

http://www.newegg.com/Product/Product.aspx?Item=N82E16817182081 nets to $80 - platinum unit

These are all quality units more than sufficient for your setup.

The combined TDP of these two is 166 W. Will you run into any issues with a 300 W power supply? Probably not. I still wouldn't feel comfortable though, a power supply is the very last place you want to look to save money. Delivering safe power and adequate amounts of power is extremely important for your components.

No, the answer is no.

The configuration you list above, plus 8GB RAM and 2 harddrives w/DVD will put your max draw at 285 watts. Bump that up to 32GB RAM and you are well over 300 watts.

And forget about overclocking. It's out of the question with that power supply and PC configuration.

While I'm a Seasonic fan, I would recommend an Antec Basiq 430W 80 PLUS Certified ATX12V Power Supply. It will allow the overhead for expansion and overclocking for roughly the same money. Or, spend a little extra and get a SeaSonic 450W 80 PLUS Gold Certified ATX12V / EPS12V Power Supply.

Go here and play with the config -> http://pcpartpicker.com/p/FEnD
Note the wattage requirements n the upper right frame.

That power draw figure on partpicker, like all online wattage calculators,
overstates draw considerably. A system with a 6670 will draw approx
200w during gaming, and no where near 300w regardless of how much
ram is in the system.

No, it doesn't "overstate draw considerably". It merely states maximum consumption (worst case) for each component. And, of course, 100W for the AMD A10 does not include additional power required for overclocking any more than 66W is the true maximum for an overclocked HD 6670. Granted, the OP never said he was going to overclock, but he is pushing the limits for a 300W supply at standard config. Just because a supply will deliver 300Wats doesn't mean it should have to do it for hours one end while gaming.

Device Low/High
AMD A10-5800K 3.8GHz Quad-Core Processor 12W - 100W
Asus F2A85-V PRO ATX FM2 Motherboard 17W - 70W
G.Skill Ripjaws Series 8GB (4 x 2GB) DDR3-1600 Memory 9W - 9W
Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive 4W - 20W
Seagate Barracuda 3TB 3.5" 7200RPM Internal Hard Drive 4W - 20W
Sapphire Radeon HD 6670 2GB Video Card 16W - 66W
Total: 62W - 285W

Bumping the RAM from 8GB to 32GB increases it's power consumption by a factor of four (9 -> 36 watts).

You shouldn't put the OP in a position where he'll experience nuisance BSODs when he is gaming.

I'm doing nothing of the kind. These calculators do overstate, you are giving bad info.

Here is sys tdp from Tom's Hardware:

http://www.tomshardware.com/reviews/radeon-hd-6570-radeon-hd-6670-turks,2925-15.html
124w - does jump to 200w during gaming

From Anandtech - sys tdp durinf crisis - 198w
http://www.anandtech.com/show/4278/amds-radeon-hd-6670-radeon-hd-6570/15

Those are real world usages for sys with 6670's.

Neither, nothing wrong with my suggestion or any similar.
Would recommend it again.

Yes, I'm argumentative when someone does not use
real world lab test usages in their replies.

So, your point is, "Yes, I'm argumentative". You see, you didn't bother with any "real world lab tests" until someone (me) bothered to show the OP why a 300W PSU is insufficient. You simply stated that "I wouldn't recommend as low as 300w, and do suggest you consider 400-450w", period. No explanation, no reasoning.

Pcpartpicker uses only the manufacturers' worst case TDP for any given product. For you to arbitrarily state that "power draw figure on partpicker, like all online wattage calculators, overstates draw considerably" is both untrue, and misleading. But then, after you tell Gekiddo that he needs to consider 400- 450watts, you tell him 300W is fine because you are unable to produce any documentation to back-up your previous claim.

Toy, if indeed you believe 300W is inadequate for his build, tell us WHY. If you believe he needs 400-450W, tell us WHY. Because, you've already told us why 300W is adequate (hence the bipolar/schizoid tendencies). Don't just post a BS answer saying "Here's a Rosewill for 100 bucks that'll do ya'.

Get off it already - you threw out wattages that simply aren't real world - period.
Not necessary for the majority of posts to cite real world lab test, does
become necessary when some suggests 285w to well over 300w when that simply is
not the case.

All the bs your posting doesn't change that.

And I never suggested 300w was adequate or fine, don't put words in my mouth.

If you read my orig post - I said realhardtech suggests a 400w unit,
that is their expertise, and that is the reason why I suggested what I did.
I trust realhardtech's psu requirements, that's what they do. I will continue
to use their recommendations as well as other reputable sources.

How is AMD's TDP spec of 100W not real world? Are you saying the product manufacturers don't know what their power consumption is?

Please provide the link to the "realhardtech" suggestion instead of just expecting everyone to take your word for it.

You most assuredly did infer that 300W was sufficient by showing not one, but two separate "real world lab tests" that show it consuming <200W on their testbed.

As for the real world tests you show, none of them were of the same configuration as Gekiddos. And how you got off on the whole HD6770 rant is beyond me as I never said a word about it's consumption (aside from the manufacturers stated TDP). Nah, you're just argumentative.

Gekiddo, the implication of the 285W worst case power draw of your system is that:
1. You'll be running a 300 watt power supply above it's zone of greatest efficiency.
2. You'll have a greater likelihood of nuisance BSODs while gaming (full load on the GPU, CPU, motherboard, etc...) if you have maxed out RAM, added a couple of drives or done any overclocking.

Please try to overlook the rantings between Toy and I, we really are only trying to help you make an informed decision.

So now believe and told us becomes infer? I did neither, you can take it any way you wish.

400 Watt or greater power supply recommended (500 Watt for AMD CrossFireX™ technology in dual mode) from amd's power req

People, ^OP is building a media PC. If he is building a pure media PC, he will not need to overclock. And the 3D graphics capability of the video card, along with the attendant power draw will not be needed.

One of my systems has an OC'd Q9550, 4 GB RAM, a GTX260 - a card that pulls 80 - 100 watts more than a 6670, a Gigabyte EP45-UD3P motherboard, 3 hard drives and an optical, and a Soundblaster card all powered by a Corsair 750TX.

Running 3 instances of Prime95 to load the CPU and 3DMark06 to load the GPU, it pulls 375 watts from the wall as measured by my Kill-a-Watt meter. Figuring 80% efficiency, the system pulls about 300 watts from the PSU.

I figure that system will pull less than 250 watts. That will put the PSU load factor at less than 80%.

Although I would spec a higher rated PSU, the 300 watt Seasonic should be adequate.

I hope everyone here realizes that the minimum power supply AMD recommends even for one of their lowest power consumption cards like the Radeon HD 6450 is 400 Watts.

The Radeon HD 6450 is only a 27 Watt card and draws less than 2 Amps from the +12V rail(s) when running Furmark. There's no way a 400 Watt power supply should be the minimum system power supply power rating for this card.

Don't take everything AMD states as gospel. Question it when it doesn't make sense.

The Radeon HD 6670 draws less than 4 Amps from the +12V rail(s) during gaming and less than 5 Amps when running Furmark. If your power supply has a maximum combined +12 Volt continuous current rating of 20 Amps or greater it should have no problem powering your system with a single Radeon HD 6670 graphics card.

The Seasonic SS-300TFX Active PFC (80 PLUS Bronze),has a maximum combined +12 Volt continuous current rating of 21 Amps.

Those recommending an ATX PS2 form factor power supply are already on the wrong track since the OP shows that a TFX form factor PSU is being used.
