This list was sent out to resellers so they can "bundle" a particular brand of the new G80 cards with an appropriate power supply. The list was assembled in only a few days, so it's not as comprehensive as it could be, but it does give an insight into what PSU's were tested and passed to work with the G80 cards.....


FOR GeForce 8800 GTS PRODUCT (please note all products on the list will be compatible):

“A minimum power supply specification of 600W is to be used with this new graphics card. The following list of power supplies have been tested and certified to be compatible. This is not a comprehensive list, but it may be used as a resource in acquiring a suitable power supply.”

GeForce 8800 GTX (please note all products with specs higher than 700W will be compatible):

“A minimum power supply specification of 700W to be used with this new graphics card. The following list of power supplies have been tested and certified to be compatible. This is not a comprehensive list, but it may be used as a resource in acquiring a suitable power supply.”

I wonder if someone made a mistake there...the munchkin 550 doesn't meet the 600w requirement and it also has a lot less 12v amperage than any of the others...like 28 compared to 36 and up i think

I wonder if anyone at NVIDIA is paying attention to what they release in documentation? Didn't the GTX you get jonny say 400w?

Guess they are just trying ot help their resellers makie some more money :rolleyes:

This list is not Nvidia's list.

And the GTX I got that said "400W" was a BFG. This is list is not from BFG.

We won't discuss who's list this is, but these units were sent and tested to the partiucular manufacturer and passed.

Where they say "at least 600W" or "at least 700W" they are talking about PSU's outside of this list. In other words, "to be safe" if you're going to bundle an 8800GTX with a PSU that's NOT on this list, please make sure it's at least a 700W PSU.

Sorry, but I don't believe that you really need a 700W PSU for an 8800GTX.
I'm pretty sure that a (for example) M-12 500 is plenty, but I'll wait a couple of days until our BFG reseller will make some tests with a 8800 GTX/GTS and I'll speak again. ;)

Jon Gerow

An M12-500 is likely plenty.

You have to realize this list came out in response to a call to vendors to provide units for testing.

In other words, PSU companies were asked to submit PSU's for approval so they can in turn be added to a list provided to resellers.

I'm not sure I get why this particular manufacturer thinks their card needs at least a 600W when BFG only a 400W. Then again, BFG qualifies their statement by asking for "at least 30A on the 12V rail." This manufacturer makes no such clarification.

And we've already seen how many 400W PSUs have that +12V @ 30A. The 600/700W is probably to deal with some of those cheap generic units with a high rated wattage but low total output.

Your psu choice will also depend on how many drives and other components that make up your system. Wether you overclock and that sort of thing. If you have four hard drives in RAID, couple other optical drives, a bunch of case fans and lights, a 8800GTX thats overclocked and you overclock the pcu, ram, and mobo, etc., etc., Plus any room for future upgrades and expansions. Then I can see why a 700w psu would be needed in such a situation. Just depends on what your whole system configuration/setup is.

Of course, but then you're raising the whole required competence level of the user up by 300%. You have to realize that the majority of the customer base isn't guys like you and I. I think BFG will be lucky to convince people that two 15A rails isn't necessarily equal to 30A on the 12V rail. :(

Well BFG seems to thrive on peoples ignorance if you ask me ..you ever look at the PSU section at http://www.bfgtech.com it's a da.mn joke

mostly all Topower PSU with no specs listed other than # of connectors and a lot of Hype

hehe, I can even understand users making that mistake. It's the 15 year old kids (no offence to anyone) posting oh-so-knowledgably on various forums that the OCZ GameXStream 600W (or similar) has 72A on the +12V rails (because quad rails always sum, don't they:crazy:), never realising that that would correspond to 864W, or well over the total rating of the unit. It just doesn't matter how many times you tell them, they read it on some website/forum, so it must be right!
:wall: :wall: :wall:

Sadly, they're far from the only company to do so.

I'd rather the PSU was a Topower and not a Powmax. ;) At least the Topower has fairly good quality components, decent over all build quality and proper protection that will keep other components from blowing up.

I think you'll find the MAJORITY of even "above average" users are still using the PSU's that came with their case. ;)

True enough ..But BFG could make better choices for their customers

I can remember about 5 years ago I bought a Q Tec and was quite proud that I had upgraded from the standard piece of poo that comes with a generic case, wasn't until I had endless problems with the PC that I investigated and found out a little about PSU's that was the beginning of my interest in PC's apart from just using them, I found forums and the great guys on them. So I suppose I owe Q Tec a thank you if they didn't make rubbish PSU's I wouldn''t be here today.

I'm big into the protection that good PSU's offer when they do go pop and as such I rate the humble PSU as the most important part of any decent PC, I build them partly for my living now and refuse to build any PC without a good quality PSU I'd rather have less money than the hassel of rubbish parts.

I was wondering.
On an overclocked E6600 + P5W DH + 8800 GTX (single card) system, will the Corsair HX520 still be such an optimal combination of quality, performance, silence, modularity and value as it seemed to be for a system without 8800GTX? Or will the HX620 or an other PSU be a better choice?

(Other hardware in that system will not be much special, 2x 320GB SATA drives in raid, DVD-writer, 2x1GB DDR2 ram)

Thanks in advance.

Oh and Jonny Guru rocks, the guy, the website, the reviews and the forums :). I wish there was something like this for every part of hardware I need to buy (so damn hard to pick the 'best'/optimal LCD screen for example! :P). The web always needs good technical data :).

Jon Gerow

Personally, I think the HX520W would be enough for a single 8800GTX setup.

I mean, if you look at the list you'll see we've got Mushkin's HP-550 up there and the Silverstone ST-60F. Not horrible PSU's, but I think the HX520W is better than those. ;)

Hi All,

I got a question concerning 2 powersupplys that I currently have in regards to Nvidias GeForce 8800 GTX. One being OCZ 600 Powerstream, Two a Ablecom PWS-0060 645 Watt Powersupply. Would eithe of these Powersupplys be sufficent to power the GeForce 8800 GTX?

All help provided is greatly appreciated. My thanks to all who respond

Jon Gerow
11-21-2006, 02:46 PM
Again, if you look at the list you'll see we've got Mushkin's HP-550 up there.

Seriously... if the PSU has at least 30A on the combined 12V rails and has either one big 12V rail, or three or more smaller 12V rails where the PCI-e connectors are on their own rail or rails, then it's not even a question that needs to be asked.

The only PSU's I'd say wouldn't be good for an 8800GTX would be those with less than 30A on the 12V rails, or those PSU's that have two +12V rails where the CPU is on it's own rail and everything else is on a second rail with a 20A OCP limiter on it.

They should both power one (provided the PS600 is working right), but I think I'd use the Ablecom.

I would much prefer the Ablecom over the OCZ unit. The PWS-0056 I had worked (and still is) working flawlessly.

I need a PSU for the following system.

Conroe E6600
eVGA 680i mobo w/ bridge fan running
Crucial Ballistix 1GBx2 PC2-8000 (1000mhz)
Western Digital Raptor X 150MB SATA HardDrive
HP dual-layer DVD/DVD Writer
Scythe Ninja CPU cooler w/ 90mm silent fan
2 120mm adjustable speed fans in a well-ventilated case
a single eVGA 8800GTS

I do plan to do a little overclocking, most likely sitting the Core 2 @ 3Ghz and running 1:1 memory/FSB @ 1066 mhz.

For a single graphics card system I have been kind of wary of these huge PSUs I'm seeing recommended. I was thinking that a solid PSU with stable amperage would easily be able to handle a single card g80 system. The one I have been eyeing is here:

Hell....to be honest I was thinking their 520w model would do just fine.:eek:
Am I completely off-base here Jonny G?

Corsair 520 is perfect for your setup.

So for the 8800 GTS (which I just bought and only has one power connector), split rail designs are unusable?

No they are useable. Why wouldn't they be?

I thought that single connector cards would need at least 30A through a single rail (i.e. the same connector). Is that not right?

No that is not correct. The system recommendation maybe 30 amps @ 12v but not for the card alone.

Jon Gerow
12-26-2006, 12:57 PM
Spectre is correct.

This comes up time and time again. People need to read more closely.

When a company recommends X number of Amps on the 12V rail, they are not recommending this because that's what the video card uses. They are recommending this for the entire PC.

THE MOST each PCI-e connector is spec'd to deliver is 75W (or 6.25A.) The PCI-e slot can theoretically deliver 75W. So AT THE MOST, a PSU will only be asked to deliver 18.75A. Typically, the slot is powered by a different 12V rail than the PCI-e connectors. So even if you don't think the rail the two or four PCI-e connectors are on, you have to consider that 75W per card is being delivered via a different rail.

Thanks for clearing that up, it made choosing one much easier. I went with the Corsair HX 620W.
