Does anyone know what amperage it will support on the 12v rail? I want to buy it with a graphics card and which I get will depend on what it supports.

The PSU has 2 12v rails, and each is rated for 16 amps. Here's the whole table for anyone who needs it:+12v1 - 16a+12v2 - 16a+5v - 15a+3.3v - 12a+5vsb - 2a-12v - 0.3a

http://us.shuttle.com/barebone/Models/SH87R6.html The page lists cards that they support... and there'a Power Supply Calculator that they link to.... you tell it what you're planning on using and it tells you if you've stayed with the 300 Watt budget. It is annoying that they don't just publish the number, isn't it?

power's there, but you'd probably be better off just getting a 36v psu separate. A big buck/boost on this will either dirty up your power if you have other 12v devices on it, or be a loss in efficiency. I've used this with bucks to take it down to 5 to provide 12 and 5v with this. haven't gone up with it.

It's 20 gauge. If you decide to solder a long run yourself, don't go any thinner. These power supplies are rated at 2 amps and the camera has a pretty good draw. The voltage drop will be too much.

The EVGA Hadron Air's PSU is 500w with 40A on the +12v rail. For this card it is recommended to have a minimum 600w power supply with 42A on the +12v rail, so the Hadron's power supply appears to be slightly underpowered. I would say just upgrade your PSU, but it seems you might possibly have another issue as well in dealing with the physical size of this card. This card is somewhere around 10.5-11" long (at least my 780 Ti ACX Superclocked is that size) and I believe the Hadron Air supports a graphics card around 10.5" which is cutting it kind of close. I'm not saying it wont fit, its just something to keep in mind if and research further if you have your heart set on this card. Also, I know this product is listed as 12.8" long, but I think thats the packaging dimensions as my 780Ti's box it came in was 12.8" long.

Hang on while I go look. There is a tag on the bottom that states 120V A. C., 60 Hz., 1.5 A. I would have guessed it would have a higher amperage need. Additionally, there is no mention of voltage or amperage requirements in the Owner's Guide.

If I remember (motnths ago) it was a 20 pin with a 4 pin optional. I believe if you use the spare, you are limiting yourself to onboard GFX (it's a 300 watt so its pretty understandable)

Yes on 2 rails. If you want to SLI 3 cards get a stronger power supply otherwise its great!

Here is where I start when I want to calculate the amount needed: http://www.extreme.outervision.com/psucalculatorlite.jsp (Although it looks like it doesn't have your CPU yet.)You'll probably be fine with an 800w power supply, although you'll need to make sure the rail(s) can handle the graphics card. Also, will you be (in the future) adding another graphics card? If so, I'd say get the 1300w one and then you won't ever have to worry about it.

Thanks - is the current (amps) within usual range for 450 watt power supplies? Sometimes I find on these cards that you actually need another 100 watts in PS rating just to get up to the 12v rail amps they want - not enough amps means "DOA" = RMA although the card is actually fine.

The GTX 660 has only one 6-pin connector on it. It gets the rest of its power from the rail.

"350 Watt or greater power supply with a minimum of 18 amps on the +12 volt rail." Taken from the box. Hope this helps!

Actually, if memory serves, this card does not require the additional power provided by the 6-pin connector since it only draws 65W maximum. This card replaced my olde GeForce 9800 which did require the additional power connector and would pull well over 100W when the advanced graphics was in use. (verified with a watt meter). I will check my system this weekend since I am installing a new monitor and let you know.

Well, that load is within spec. I have not run mine this hard, but at this price it seems worth a try. I have had excellent performance thus far at 48V, probably 2-3 A.

Will it support it; Yes. Also under full PC load you will be around 500-550w (the cards alone pull 400w together). This will put you right in the efficiency "sweet spot" (92% at 120v). Looking at the graph you can see efficiency starts to decline over 50% psu load. Your idle load will drop below the efficiency "sweet spot" but only by 2%.

It works fine 24v-12v but only 20amp I need higher amperage, it doesn't even run the headlights I installed. I was told to get a 48v-12v 35amp works better for my system.

I believe, based on Replacement Power's website, there is single 12 vole rail with 14 Amp current (for the 420/280W version that many have received). The 12 volt current is the most important power parameter (more so than the total power) for modern computers.

I'm not sure but on the asus web sight there is a configurer where you input all your devices and it tells you how big of a psu you need. This psu has a single rail 12v with over 80A. I run two 560tis, i5 3570k@4.2, 7fans, two 1t ssds, 4 500g hdds, and bluray rw 2t external drive, and hopefully soon to upgrade to 2 gtx980s and I know it will handle all that.
