Hi,
Would the following components be OK with a 500W PSU?
AMD A8 6600K 4.2Ghz Quad Core Asus A88XM-A HDMI CPU Graphics Motherboard Bundle
Sapphire Technology AMD Radeon 7750 2GB x1
6GB Crucial BallistiX Memory 3x2GB Module DDR3
500GB Western Digital Caviar Hard Drive
2 Generic CD/ROM Drives
Looking to put all those components in this case

My PSU comes with case, take a look at the link
Thanks for all the replies :) 
Could someone just provide a clear and concise answer? It appears this thread has sorta gone off topic :p 
I just need a yes or no answer from a professional (which I am not :(  )

I'm trying to make a cheap Console Killer using parts salvaged from my previous build :p 
Cant wait for GTA V PC!

Yes everything will fit and the PSU is suitable. But not any 500W PSU will do the job. Please specify the brand and model. :)

7750 is not officially supported for hybrid crossfire with A8-6600K (only HD6450, HD6570 and HD6670).

What is your PSU?

Not doing crossfire only 1 GPU :p

I mean hybrid crossfire with your integrated GPU in your APU.

You graphic cards consumes 220 W at full load. And lets say APU consumes (all CPU cores and iGPU at max load) around 130W max. That is 350 W plus lets say 50 W for motherboard and RAM and lets say 50 W for peripherals. That is 450 W at full load (I mean true full load, the worst case scenario). That no-name PSU will not be able to handle it.

Sorry, I'm a bit of a noob when it comes to self builds :p 
Do you think it will work though?

Yeah, trying to stick under £200. Used up about £170 so far

OK then. I'll look at a branded one.

Well, it is practically the same as no-name one. And none of those very cheap PSU can't actually deliver their claimed power.

Also, you obviously don't need APU, but rather a "classic" CPU. So better get some AM3+ motherboard and some FX-4300 or FX-6300, or something like that.

Don't get me wrong, I use APU, but since you are using discrete graphic card and not even crossfireing it with iGPU, you would be better off.

That's just an extreme overkill in terms of wattage and still not a real brand psu. There's no way that the 7750 consumes 220W. If you saw that number in some review, it was probably consumption of the whole pc with a pretty high-end cpu. The card certainly won't take more than 100W in load (probably much less, a lot of these cards had tdp's around 60W). I don't see, how your build could take more than 250W in peaks even with a moderate overclock.
In terms of PSU, I'd be looking for a quality 400W. 500W at most if you can't get rid of those thoughts about reserve (which will already be on the 400W) or future upgrade to high-end components (which won't happen anyway and a good 400W could still handle). Even that will already be a bit at the cost of efficiency, since you will be loading the PSU at about 15% in idle and 40% in load (and generally, the psu's are most efficient at higher loads).

EDIT: as for the hybrid crossfire, there's probably no point with your card. It can be useful only with some lower-end cards. With yours (if it is actually possible), I wouldn't expect any performance improvement.

EDIT2: The components should work together (as long as your ram is ddr3), but it would be helpful, if you listed what you are actually buing and for how much. My guess would for example be, that since you have a dedicated graphics, you could find a more advvantageous cpu than the apu. We're not talking about huge differences, but still...

The power consumption figure is from here: http://gpuboss.com/graphics-card/Radeon-HD-7750

This site lists component power consumption not of the whole system, but it could be that they made a mistake.

It is not my fault that none of the manufactorers give us the actualy usefull information about their products. Like the max power consumption instead of totaly useless TDP.

No offense intended, but I serioustly don't understand the obsession with pages like gpuboss on tomshardware forums, when it's so easy to google a proper review, with a proper real-world comparison of both consumption and performance. The only thing that I would consider somewhat useful or credible from gpuboss are the benchmark results, and even those have to be taken with a pinch of salt when comparing real-world performance.
As for TDP -- yes, it can be a different from the real consumption. But since the times of Pentium 4, I haven't seen any product, where it would be lower than the actual consumption. So I think in the sentence where I used it, it makes sense. Anyway, just find a proper review if you want to know more.

TDP has nothing to do with max power consumption. TDP is marketing bollocks, that means something like this:

"The Thermal Design Power (TDP) is the average maximum power a processor can dissipate while running commercially available software."

Which is complete bollocks. At full load, power consumption will be higher than "TDP".

And BTW, those review site are also useless, sine thy only measure total system power consumption. And not even that, they measure it at the PSU input, so it is even more useless.

Yes, so some number on some site, which you have no idea where it came from is much more useful :) 
Some sites actually list the consumption of the single components (anandtech? I'm not sure and too lazy to check). About TDP, stop just repeating what you heard around the forums :)  Yes, I agree that the TDP isn't anything too accurate or official, but if you have been watching hardware for a couple of past years, you see that up to a few known exceptions, it's a pretty good UPPER estimate (I haven't said that it's tight, though, at any point).

And I don't see, how the numbers for the whole build are not useful, when all the other components are usually listed, (including the psu, so you can find its efficiency and account for it) and very often you'll find a comparison of many different graphic cards with the exactly same rest of the rig.

Anyway, this is nothing against you, I see that half of the users here answers exactly the same way. I don't really understand why but I guess I'm not going to change it, so just carry on and I should probably move on to something more useful than tomshardware forums (oh, the power of procrastination...).


EDIT: Before you start bashing me for that: when looking at reviews listing consumption of single components, be always very critical to where the data comes from. A few good sites can give accurate measurements, but sometimes the values are just read off some completely random software, which may just invent the values (so in the end about as good as gpuboss :)  ).

Thanks for the detailed answer. I totally agree that the figures from GPUBoss do not apply to me, as I am planning for the 2GB model as opposed to 1GB.

Yes it is. Because at least it is the actual max power consumption. Even if it is completely made up, it is more accurate and more useful than TDP od full system power consumption at PSU input.

P.S. No offence taken. Just discussing.

I am not claiming that this card consumes 220 W at full load. I am just using the only information that I could find about it, and posting an answer based on that.

Sorry about the OT :)  I already tried to answer in my first post. The system should work as it is (even with the original psu, though I wouldn't recommend it). If you don't want to spend much on PSU, something like Corsair CX430 will do for the build. If you have extra money, you can use for example the xfx michaelhall posted, it shouldn't really make much difference.
A guess that answers what you asked about. I still don't see any info about what you already have, what you want to buy and at what prices, so I can't give any more advice.
