January 28, 2009 7:08:41 AM

I went to a nearby shop to get myself a new graphics card. And he says he only has the XFX 8600GT, 512MB DDR3 or the XFX 8800GT Alpha Dog Edition, 512MB DDR3. I know the 8800GT is better. But is it worth the price difference? I have to pay 100$ extra for the 8800GT. I have a 450W power supply and the guy at the shop says you need to upgrade the power supply to run the 8800GT properly. Do I need to upgrade it? My power supply came with the case. The price difference is including the price of the new power supply. Please HELP!!!

8800GT is even faster than 2x8600GTs in SLI,its completely worth it.

There is alot of bad psu advice out there. You do not need to upgrade your psu. A 450 watt psu can run any single gpu card.

If you want to play modern games, you'll need the 8800gt.

How have you tested its accuracy?


i had a 250 watt power supply and according to that site i should be able to run my system at 208 watt. the box of my graphic card said i needed 450 watt, but i installed it on the 250 watt and it ran no problems.

There should seriously be a law about current PSU advice/advertising.

Wattage is far far far far far LESS important than AMPERAGE!!!!!

Example you could have a 550w PSU but if it only kicks out 18 amps on the +12 rail its sh!t.
Whereas you could have a 400w PSU that gives you 36 amps and this would run a 8800gt perfectly well.

The packaging on my BFG 8800gt ocX (default clock 700MHz Memory 1000MHz Shader 1728 MHz) states........
"425W PCI Express complient system power supply with a combined 12v current rating of 28A or more"

So if you had a 450w psu with 2 x 12v rails at 18Amps each..........your good to go.

Personally I would reccomend a single rail PSU with a large amperage. (750w 60a, something like that)

Please dont underestimate how important a good quality PSU is.

I run SLI 8800gt's on a PC Power & Cooling 750w Silencer, nice PSU.

Agreed, It IS all about the amperage as amperage is the true ability of the PSU to do "work" Just as you could get shocked by a million volts and not suffer from it.... but @ 1 amp you would be dead. Under amping a system will probably cause the PSU to fail and possibly damage other components as well.....

^ I was just going to ask for the Specs on the PSU.

If your 450W PSU has at least 26A on the 12V rails you will be ok. This is the requirement for the 8800gt.

I had a 400W that came with a case SEVERAL years ago. I think it has like 12A or something like that. It toasted after a year, gladly it didn't take anything with it.

There are 450W PSU's and there are 450W PSU's
January 28, 2009 1:35:29 PM

So should I tell the guy to first let me use the 8800GT with my 450W PSU and then if there is any problem then change the power supply? Also what is the difference between the regular 8800GT and the Alpha Dog Edition?

Also the utility on extreme.outervision.com says that I need a 461W power supply.

I would first pop the top off you case and tell us what it says for the 12v rials.

XFX branded their 8800GT's the Alpha Dog. It's just marketing. I think the only one XFX card that holds a non alphadog and alphadog distinction is the 8800GTS. Because they made the 8800GTS 320 and 640, but then used the 65nm chips again in the 8800GTS 512 version and branded it Alphadog.
January 28, 2009 1:51:38 PM

The PSU says that the yellow colour wire has 12VDC, is that what you meant? If so then it has 25amps. Also I dont think that I have a 6 pin power connector. But I have 3 free molexes

It would be printed in the side of the PSU.. it would look somethign like this:

We want the +12V specs

25A might be ok for an 8800GT. what does the rest of your system look like? PSU, # of HD's and opticals, etc?
January 28, 2009 2:13:42 PM

It does say +12VDC Sorry.... and I have one 250GB HDD, a 9550 AMD Quad Core not overclocked, 2GB RAM one DVD writer and a 22" monitor.
January 28, 2009 2:19:55 PM

The alpha dog 8800gt I got has a fan that cannot be speed regulated, its only a 2 wire fan. XFX will send a new fan for free but Im lazy and dont might the loud fan.
January 28, 2009 2:43:38 PM

Did you say $100 more for the 8800GT on top of the price of the 8600GT?

8800GTs arent being sold anymore, but they were last being sold for about $120. The 9800GT is EXACTLY the same as the 8800GT and costs about $100-$120 for it.

If the guy tries charging you over $150 for an 8800GT you need to slap him in his mouth, tell him to go pound sand then go to Newegg.
January 28, 2009 2:52:54 PM

I wouldn't mind if mine ran at a constant speed as I have to turn up the fan speed anyway to keep it as cool as I want and where it probably should be at anyway. though I only turn it up to 75% fan speed but got pretty good cooling in the case.

And don't overestimate it, either. He should not get a 750w psu, it will be inefficient, a waste of money and time and just plain unnessesary.

I dare you to find a 450w psu that is unable to run a 8800gt (and don't just point to the extreme overestimates that are on a 8800gt package).

+1, anything more than $150 for the 8800GT is total rape. If you can do your own install, look to newegg.com for a much better deal.
January 28, 2009 3:52:33 PM

I ran my 9800GT - MSI factory overclocked on a 400w power supply. The 9800gt is the same exact card as the 8800gt.

My 12v ratings were dual rail 14 amp on each.

Do yourself a favor and goto newegg.com and buy a 9800gt or 8800gt, which ever is cheaper. I seriously doubt that you will have a problem with your current power supply.

If you want to spend $150, get an Radeon 4850
January 28, 2009 4:23:50 PM

Why are you looking at an 8800GT in 2009? That's yester-tech.
January 28, 2009 5:34:56 PM

You are being over charged.

a year or more ago I purchased an 8800gt 512mb Factory Overclocked edition for about $110 after rebate.

Here's the breakdown:

an 8600gt is a terrible card almost worthless in relation to its neighbors.

a 9600gt is a decent card. way better than an 8600gt. nvidia improved it to compete better with ATI

A 9600 gt is way better than an 8600gt. Because Nvidia knew the 8600gt was awful and no one would buy it.

A 9800gt is the same card as an 8800gt with a new sticker on it.

A great ATI card is the 4830 it retails for $99 much faster than the 9800gt.

A 4850 is way better than all of them and prices start at $130

4850 seems to be in your budget

Incorrect.

if you run a 750 PSU like mine with ...say...550w of clobber the EFFICIENCY is aroung 86% or something.
As for overinflated blah blah etc, what about future upgrades? what about build quality?

And my 750w Silencer only cost £90 including shipping and VAT.

Looking at my e-penis right now............. its still small thanks ;) 

However if the amperage is enough, indeed, he has no reason to upgrade.
This always happens when ppl dont reveal their system specs in opening post ;)

http://www.tomshardware.com/reviews/4830-radeon-crossfi...

Shows the results of a 4830 vrs a 9800gt

The 9800gt is a factory overclocked card but if it wasn't, I am not so certain that I could say that the 4830 is much faster.

For about the same performance the 4830 can be had that I could probably say with some level of certainty.

I'm not sure what clobber is, but the OP will idle somewhere below 100watts. A psu running at below 15% is not running efficient. The 86% is when running at higher percentage. Look it up :) .

Here's the breakdown:
an 8600gt is a terrible card almost worthless in relation to its neighbors. The 8600GT is fine for playing newer games on lower settings. The DDR2 version sucks, the GDDR3 version is much better. It runs shader heavy games like CoD4 (or even 2) quite nicely because of its high clocks. However it's SP's and bus is really a limiting factor. It performs better then a 7900GS in new games, but worse in older games (with lower shaders).

a 9600gt is a decent card. way better than an 8600gt. nvidia improved it to compete better with ATI. Yes.

A 9600 gt is way better than an 8600gt. Because Nvidia knew the 8600gt was awful and no one would buy it. Lots of people bought the 8600GT.

A 9800gt is the same card as an 8800gt with a new sticker on it. The 9800GT is 55nm and has tri-sli support.

A great ATI card is the 4830 it retails for $99 much faster than the 9800gt. The HD4830 is slightly better then the 9800GT. Usually neck and neck, even. (drivers)

A 4850 is way better than all of them and prices start at $130. Yes.

4850 seems to be in your budget


I fixed your post, sir.
@OP, why don't you just install it yourself at a much cheaper price. It's really quite easy actually.
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
An HD4830 for $85 After rebate, shipped. It's usually faster then the 8800/9800GT too :) . And, it will only get better with newer ATI drivers.
January 29, 2009 1:29:16 AM

buy all of your stuff from newegg from now on, and avoid the 8600 like the plague. Dont be fooled my PSU jargon, i was running two 8800GTS in SLi on an Antec HE 500watt for a while with no issues whatsoever. Granted most 500watt you cant do that with and have it stable but calculate what you have and make sure your PSU is solid. General rule of thumb a heavy power supply is a good power supply.
January 29, 2009 4:24:27 AM

Why confuse the OP so much :p  . Dude, either get the ati 4670 or wait for the 9600GT green edition. You wont require any psu uppgrades, these cards are cheaper than 8800gt and arent too worse than 8800gt.

Hey, this thread has been inactive more than 6 months. I am just wondering how you guys think of GeForce 9600GT XXX Alpha Dog Edition vs HD 4850.
August 21, 2009 10:14:10 PM

8800gt alpha dog edition says it requires a 500watt psu and ive been running mine on an antec tp3 430 watt psu.you should have no problem what so ever




Hey, this thread has been inactive more than 6 months. I am just wondering how you guys think of GeForce 9600GT XXX Alpha Dog Edition vs HD 4850.

-go for the hd4850 it has a good price to performance ratio and easily beats the 9600gt

Very late response, but looking at your name, i believe that you are a german:) 

Also... die kenn ich ein bisschen

The germans (i'm a dutchman btw) do have a lot of technical knowledge, especially when it comes to psysics, chemics, cars and technical stuff, such as computers :p .

So when you say that you were able to run a 8800 GT on a 450 watt PSU, then i'll believe you immediatly. Respect da zu :) 

But the germans also don't find it necesarry to replace things if the old stuff still works good enough..

Clearly, if the old stuff was of some good quality, then you are absolutly right.

But keep in mind that most PSU's that come within a case are Terrible (mit Kapitel T).
they are lightweight, they are not sturdy cased and sound like a empty can of diet coke when you tap on it or when you put it gently on the table. With the current enabled, they make lot of noise most of the time. they also have very little compatibilty when you look at the very MINIMUM amount of component cables. If such PSU's have a lifespan of 3 years, especially when used with gaming, let alone overclocking, then they were a 1 in a 100 that was lucky enough to survive.
the reason why those PSU's are absolutely crap (except for basic systems that are not very often used on a daily base) is simple: they come with cases between €30 and €50 (in pounds that would be about the same in this case). More expensive cases nearly do not come with a PSU. So if the case + PSU is about max €60, then what can you expect from such a PSU?

It is clear that such a PSU is not even recommended with a quadcore, let alone in combi with an 8800GT.

However, 750 watt is indeed an overkill in this situation. 550 - 650 watt is more than enough, also if you want to upgrade later on. Just do not spend less than about €40/€50 on a PSU, as this component is indeed important! many people do not want to spend more than 30 on it, and are underestimating that. If you're cutting on the PSU and buy a 400watt of €20-30, you gotta tell me that you only use your pc for the internet and e-mail, and that you don't mind knocking on your neighbours door, might your pc crash after 5 months. Or else you are playing hangman with your system-stability.

for €50 you even got a 450 watt PSU, even with modular cables and PCI-E 6-pin support. And then you are fixed. And then you can even try a 8800GT.
