How many miliwatts does this card use or how much can I expect this to shorten my Macbook Air's battery?

I have absolutely no idea how to determine this, sorry! I can only stress that you make sure that it fits, because it does not fit flush with my late-2013 Retina MacBookPro so I do not leave it in there. I benchmarked the card with Blackmagic Disk Speed Test and its nowhere near the speed of the internal Apple SSD drive so its really just extra space for stuff I don't always need, like an archive for app install files (for those that aren't backed up in the App Store), or other files you don't want to eat up your local disk space (read: pr0n). Hope this info helps! :-)

I haven't noticed it shorted my battery life. I don't know how many milliwats. I am satisfied with the product. It operates a little slower, but not too much.

The card itself is rated by Nvidia to use about 155 watts. If your just running one you won't need to buy a real heavy power supply. the computer I built with this card calculated to use just under 400 watts overall (and I put a 4th gen i5, 8 gigs of ram, 2 hard drives, multiple fans, 2 DVD/blu ray roms, and a decent mobo) and I used a 500 watt psu. Just make sure your power supply has the proper connectors ( you will need an 8 pin and a 6 pin connector to power this card, careful not to confuse your 8 pin motherboard connector with your 8 pin video card connector.)

It could work for that load for 3 hours assuming they are modern tube type amplifiers, probably not. Understand that amplifiers are typically rated in power Output, not the power required to operate. Most modern tube amps are considered a type A-B amp which typically draws at least twice the power to run as power output rating. So you have to figure/guesstimate (2x30wx2=120w) + (1.75x5w=8.75w) + the MacBook Pro & USB hub so you're talking ~ 150w minimum. 150w/13.8=10.8 or let's call it 11 amps per hour of operating. The batteries 35AH rating is usually listed for a standard 20 hour discharge period. If you use 11 amps per hour discharge rate you will not get a full 35AH out of the battery. This battery will probably be closer to a 30AH rating when discharged at 11 amps/hour. In addition, discharging a battery that deeply will shorten it's life significantly. Check you equipment for the rated power used, should be on a label or in the manual. That'll give you a more accurate value to calculate with. Once you have a good value, look for a battery with twice that amount. i.e. If you need 12 amps/hour from the battery to run the equipment then you'll need a total of 36 amps to run for 3 hours so look for a 72 amp-hour or larger battery. If possible find out the battery discharge rating for short term. If a battery is discharged in a shorter time, with a higher current, the delivered capacity is less.

Do not think it works in your MacBook Air, this connector convert Firewire 800 to 400; you need to support firewire to USB converter, visit: StarTech IEEE-1394 FireWire Adapter 4 Pin - 6 Pin M/F (FIRE46MF)

Hi Sami,This panel puts out 27W directly, but some other users have determined that the output may be higher, even up to wattage in the 40s in extremely lighting conditions. You may be able to trickle charge small laptops such as 11.6-13" netbooks and computers like the Macbook Air with them turned off, but you will not be able to draw enough continuous power from this panel to use while charging and anything above a netbook will be tenuous.

I am using a 650wattt power supply. The card needs a power source other than the mainboard.

I wouldn't recommend it. This is CL10 memory and at 1.5v. Ideally I think the mac mini wants 1.35v at CL11. I've actually tried CL9 before and the mac mini was not happy. CL10 is cutting it close.

600w minimum, but the draw is around 275. So if you ever want to run dual cards youd want to look at 850 and up.

The spec sheet says the minimum power requirement is 300 watts for the system and 65 for the card, so it would seem your system is right on the edge.

hiThis type of card has a low consumption approximately 150W , I think with that source will not have problems. I have a 500w and have not had problems with that card.

the card alone at TDP will use close to 250 watts... so unless you have an atom processor and no HDDs... more watts the better ;). Plus most psus are less then efficient, My guess is that 350 watts is more like 300

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%.

I believe the documentation calls for a 750W power supply, though the power usage of this card fluctuates a lot. I haven't seen the card draw more than 410 watts from the wall, putting my total system under 650W at full load. I have been using an EVGA SuperNOVA NEX750G 80PLUS Gold and it has been running fine.

I would love to know as well because when I bought it it had the best reviews but I know for a fact the charge only lasts over an hr. As a matter of fact my MacBook is constantly plugged in.

Its a low profile card, the only power it needs is that fro. The pcie slot. So just plug in and go

I have used this with a 500GB drive originally inside a MBP, and I connect it to the FW port on the same MBP, and so far I have not had any problems. I haven't had any need for additional power.

Depends on the rest of your hardware. This card uses 150w, you will have to calculate the rest on your own.Minimum recommended is 500w.
