Here are my PC specs:

250GB SATA II 3.GB 7200RPM 8MB

4 GB PC6400 DDR2 800

BIOSTAR TA790GX A2+ AM2+ HDMI MB

OEM AMD PHENOM II X4 940 BLACK EDITION 3.0GHZ

RADEON HD 4870 1GB

I do not want to overclock my PC, however, I am planning on adding another GFX card for the crossfire mode. Is 680 watts of power enough to handle this?

No.. only 22 amps MAX for the 12v rail. They inflated the 3.3v and 5v specs so they could get away with calling it a 680w PSU.... Never use wattage as reference when comparing PSU's. Look at the amount of amps available to the 12v rail(s)...

What he said and i can gurantee you the psu you listed it will have trouble even with one 4870 let alone 2. When it comes to psu's never go cheap.

Thanks for the advice. However, I dont want to spend $100+ just for a PSU when I can go cheap and get a decent one for half the price.

So, you don't mind spending about $700 (give or take some, depending on where you're buying all your parts from) and then throwing in some piss poor PSU? You do realize that if you're PSU fails while you're using it, it can not only destroy itself, but it can also take out anything that it's hooked up to? That means your MB, video card and anything else... So you're willing to jeopardize your entire PC for not wanting to spend a good $80-130 on a good, solid PSU? Especially if you think you might add a second HD4870 1GB sometime down the road...? That's just foolish.

I'm too lazy to edit my last post. Here are some good PSUs you should look into if you're planing on running 2x HD4870 1GB in Crossfire.

Corsair 750W= $119.99

Cooler Master 700W = $119.99

PC Power&Cooling 750W = $119.99

If you don't want to Crossfire, then find a good, solid 500-600W PSU. Expect to spend at least $50-70 on a good one.

You're more then welcome to do as you see fit, it is your money you're going to putting into this computer.

There is a difference between saving and wasting money. Saving would be buying a decent durable PSU for 50-75 dollars, wasting money would be buying that piece of crap you claim is a PC PSU.

If you're just going to use a single HD4870 buy the following

http://www.newegg.com/Product/Product.aspx?Item=N82E16817182030

For SLI, I would get a

Or to be safe,

What he listed is a lot better than what I posted. Some of them have rebates so they are actually about 100 USD. If you have the money and plan to do crossfire I would stick with any of the three PSU he showed.

that PSU will melt under the strain of just one 4870. If you tried to crossfire with that PSU you will be risking serious damage. It could probably handle a 4850 though or a 4770 even better.

Also don't buy from that site, only buy from newegg or from tigerdirect (because no tax for CA residents and usually have 2 dollar shipping deals on items over 100 dollars)

It still amazes me that people will purchase some very hefty hardware, and assume that the power plant of their machine is an unimportant part. Just because a power supply doesn't have "GAME BOOSTING EFFECTS" or show up on benchmarks doesn't mean it should be skimped on. Get a quality brand, never ever use a PSU that comes with a case for a gaming machine, and research known issues. I have had to repair far to many machines for friends that died because companies like emachines put CHEAP psu's in their rig.

Newegg charges waaaay too much for PSUs. Why would I spend more money for the same features? The A Power is all I need: 680w, over voltage protection, and short circuit protection. The Corsair can blow out just like any other PSU, so I dont want to look like a fool wasting $180+ on the same features.

Thanks anyway for the comments!

You're not listening to what we're saying. The wattage rating means nothing. 22amps to the 12v rail is likely not enough. That's only 264w available to all of your 12v devices. They inflated the amp output of the 5v and 3.3v rails so they could claim the 680w rating. They did this to make the PSU look much better than it really is.. It may work, but it may overheat and fry your components as well...

thats awesome, go for it. but I did this exact scenario, with a single 4870 and the PSU fried. Its going to make a hissing sound like a snake for a while then the inside will melt. for $20 I guess its worth a try.

That psu should work but for how long? Also 750w and it only has 44 Amps total. Its most likely poor quailty, never heard of A-power. You get what you pay for , Here's a 600 psu for $70 and has more Amps on the 12v rail then that psu and is better quality.

I agree, it probably wouldn't last more than a few years. But OCZ only has a 3 year warranty. I would go with a 550w BFG or Power Series Rosewill instead, since they have a lifetime warranty...

Sometimes you get lucky, other times you end up with a fried computer. Just because it works, doesn't mean it works well. And it definitely doesn't mean that it will last a very long time after some heavy gaming...

Did you pay no attention. Total wattage means NOTHING. What "570w" PSU did you get. Maybe you got a decent one, on sale. Or maybe you are just lucky, or your PC is gonna fry tomorrow. I would advise people not to listen to you, as you obviously don't fully understand what you are talking about.

3.25 pounds seems kind of light for a 750 watt power supply. Overvoltage protection can still fail. Although there's no need to spend $100 on a power supply, $40 may not be enough for the kind of power you need. It's your money. I just hope you have a good sense of humor when things go bad.

Ewww a meager 600w for a lot more money and a small amp upgrade? For all I know that could blow up just like any other $20 psu

Anyway, I decided to look at this as my final verdict.

Just go for it. You're not going to listen to reason. Amps are the amount of available power on a rail (Amps x Volts = Watts). Yes, that 600 watt PSU is more powerful than that cheap so called800 watt PSU you're looking at, and you can bet every spec on that cheap PSU it is greatly exaggerated. Each rail on a cheap power supply is tested with minimal loads on other rails -- this is not a real world situation. There is no way that PSU is going to give you the rated amps with all rails under load. Not to mention cheaper soldering jobs, components, and safety features.

Keep this in mind -- that 800 watt A-Power PSU weighs just as much as a typical 300 - 400 watt PSU. Something smells fishy here.

I'm beginning to think you're joking with your outrageous comments. You do not need the most expensive, name brand PSU as some people would have you believe. You do need a quality one, and most companies that exaggerate the abilities of their products are not quality.

No, sorry, I'm not joking. Brand names can blow up just like anything else. Case in point, I bought a Sony TV, and right out of the box, it had numerous problems (turning off for no reason, random screen glitches, and a weird buzzing noise coming from the back of the set). Your just paying too much for the name. Just because its says 'A-Power' instead of 'Corsair' doesn't mean its cheap. You haven't used it before so your credibility is questionable. I made up my mind and I'm gonna purchase the 800w instead of the overbloated one you suggested. Your minds made up, so is mine.

Sony isn't exactly a quality brand (no mass producer really is), and you're right, anything can blow up but some things are more likely to blow up than others. I'm a little confuesd why you asked for advice if you're not willing to listen to it, but I guess you like to learn you lessons the hard way.

In any case, we are in agreement that you don't need name brands. We are in dissagreement that you do need a quality product and I've already explained what's wrong with the power supply you're looking at.

550W might be good for a medium/ low end machine, but for my rig, I need more than that. How long will that last until it buckles under the pressure of 2 Radeon HD 4870s is anyones guess.

Good God man listen to us you dont need a $100+ psu but you dont want a sub $50 psu ethier. You get what you pay for. That 800 watt psu weight only 4.5 pounds which is what you expect from a 350 watt psu. and descent 500 watt psu weighs 7+ pounds.

Ewww a meager 600w for a lot more money and a small amp upgrade? For all I know that could blow up just like any other $20 psu

Anyway, I decided to look at this as my final verdict.

I would trust that "550w" Corsair over any of the PSU's you have listed as alternatives.

Most people way over-estimate power requirments without even understanding power distributions in the PC.

Here, do some reading over at Jonny Guru and learn a little bit about PSU's.

**EDIT**

Also, I can find no website for A-Power, that is always a bad sign. Can't find any information on the actual unit, another bad sign.

LOL. This is really getting funny. A quality 550 watt powersuply isn't good enough for your "high end" system, but a cheap power suply with inflated specs is? Most people wouldn't even put that A-Power unit in a budget system. The only reason they say that power supply is 800 watts is to get gullible people to buy it. You could restamp that Corsair power supplyto says it's an 800 watt unit, and it would still be better than the one you're looking at.

How well do you think that too good to be true power supply is going to regulate voltage?

It's like when you buy an amplifier for music. There's a big difference between maximum power ratings and continuous power ratings, or PMPO speaker ratings (you know, the computer speakers that claim 1,000 watts PMPO but are really 15 watts at most). It's your money. If you like to be taken for rides, I have a ton of awsome stuff to sell you.

It would last a lot longer than that A-power would. I get more output on my 12V rail from my 550W PSU than that 800W PSU gives on its 12V rail.

I guess I got some of you ticked off for expressing some reasonable concern. To make it a little more clear for you, when I built my Gaming PC, I ordered a PSU (a dam good one). The quality was very similiar to the ones you people suggested here on this very post. It was a Crossfire 585w SLI ready, met the standard testing, lots of good amps, and stated the usual momo jumbo the product had printed on the box. Everything was fine and dandy until about two weeks into Dead Space, I heard what sounded like the 4th of july going off inside my new Rig. I decided to never trust brand names and go for something a little less expensive, yet can get the job done. Sorry if I made anyone upset. I Just want to clear that up. I'm going to order this thing cause my PC is collecting dust.

Thanks for the comments!

BTW how much did you pay for it? And I will bet you any ammount of money that it wasn't a good quality PSU, as all good quality power supplies come with a decent warranty. For example if you pay $100 on a corsair psu it has a 5 year warranty, so it is going to last ATLEAST 5 years, whereas you pay $40 on a cheap one and you will be replacing it every 1- 2 years, so it will cost more money. Anyway all of these people have given you good advice, so go and learn thehard way.

What brand of PSU was this "585w SLI ready PSU". Just because it "met the standards" does not mean it is a good PSU. Companies often exaggerate (plain out lie IMO) about there product capabilities. It is up to the buyer to do the research and find out just how good a PSU is before buying it.

And yes, it is possible for a high quality PSU to die, but it is lot less likely. Also good PSU companies will stand behind their products and replace the bad PSU, plus anything else in the PC that it takes with it. I can guarantee you that A-Power brand won't stand behind that unit. Just try and find a website for them.

You have not made me upset. I just don't understand why you would come here and ask for advise, just to act like you know more than everybody about PSU's, and ignore the advise given? You have experienced what can happen with a bad PSU, I would think that would motivate you to try and avoid that again.

Exactly. IMO this guy just came here because he thought that we would tell him that he was right and when he realised that he wasn't he got all upset. :P

Pick up ethier Thermaltake,OCZ,Antec,Corsair,Pc Power&Cooling, Middle to Upper-ended Xion,Coolermaster or Ultra PSU's. At least you know what you are getting, Just by lifting the psu up and checking the weight of it, not "cable weight with it" you can tell if its been built good with quality parts. I had a cheap psu about 5 years ago and it looked mean and could pump out the power but a year or so down the road one the 4 pin molex line went dead. So ended up buying a upper ended Ultra psu and it weighed 4x heavier then my last psu and its still working to this day in someones else pc since I couldnt use it anymore.

I'm too lazy to edit my last post. Here are some good PSUs you should look into if you're planing on running 2x HD4870 1GB in Crossfire.

Corsair 750W= $119.99

Cooler Master 700W = $119.99

PC Power&Cooling 750W = $119.99

If you don't want to Crossfire, then find a good, solid 500-600W PSU. Expect to spend at least $50-70 on a good one.

You're more then welcome to do as you see fit, it is your money you're going to putting into this computer.

neatfeatguy

Okay, I decided to wait an additional week for my next pay check and order either those Corsair 750W or the PC Power&Cooloing 750W you listed. I came to my scenses when everybody started barking at me like ravenous dogs:P

Looks like Dead Space is gonna have to wait too lol!

I am going to recommend this XIGMATEK because it has 72 amps on the 12V rails, 2 x 6Pin + 2 x 6+2Pin PCI-E connectors, it is modular, and has a limited lifetime warrenty. I have this Antec. I wish I would have gotten that XIGMATEK because it was modular but my antec serves me just fine since I only am using on graphics card. That antec doesn't really have enough connectors for SLI.

When you plug a cable in to the power suply, the port lights up like some kind of star treck movie. It's a good power suply too.

While that Xigmatek looks like a pretty good unit, it does not have 72a on the 12v rails. It has 4 12v rails, and each rail can distribute upto 18a per rail. But the PSU can only supply a total of 52a to the 12v lines. If that PSU could put out 72a on the 12v rail, that would be 864w. That's too good for a 650w PSU, LOL. But being able to put out 624w on the 12v is pretty good for a 650w.

Lol never seen so much good information fly over someones head so bad, these people are absolutly correct, you need a good quality PSU, dont you get it? If you get a cheap one the GPU you want likely will run slow as hell because it isnt getting enough power on the 12v rail, yeah you may get lucky with a cheap power supply, but one day you will realise what a waste of money it was, get a good one for around $100 or just dont even bother with the rest of the hardware, PSU has to power everything, people who cheap out on PSU's have no idea what they are doing.

It's a quality PSU, that's the thing about it.
