I ordered the EVGA GTX 750 Ti 2GB under the impression that a 300 watt power supply would be the minimum required to run the card, but after receiving the card in the mail today and checking out the box, I found that the box states a 400 watt power supply is the minimum required. I have a 300 watt power supply, which is why I ordered this specific card. Everything I read before ordering it stated 300 watts as the minimum, including the product specifications for the specific card here on EVGA's website.
I don't know what to do with this card, now. I obviously don't want to open it and install it if it really needs more than what I have. Does anyone have any idea why there is this discrepancy?

I see what your saying it does say on the website a 300 psu minimum not sure what to tell you either send it back or get a better psu..

First what power supply do you have?
Also, what are the other specs in your system? CPU, SSD/HDD's, etc.
I have the 3753-KR model and on the box it does say a 400 watt or greater with a minimum of 20 amps on the 12v rail. Thing is though that is based on the 750ti paired with a old i7 960 CPU, which had a max TDP of 130W.
Depending on your CPU I think you'll be fine, the card uses ~60W or so max. Even with mine folding it doesn't use that much power, 135W total system draw with a 2.13 GHz C2D with the 750ti at 1412 MHz.
I will either find a way, or make one. ٩(๏̯͡๏)۶

You should be fine, I have a gtx 750 ti with a 300W PSU - Max 18A on 12V rail. Its in my Dell and its worked flawlessly for 3 months. The card specs have been updated to say that 300W is enough too.
Edit: I can't post links, but just look at products on EVGA's website, and go to the 750 ti and it says 300W is the minimum. The boxes were made before the change.

I would never use such a low wattage PSU. IMO, the minimum these days should be 600. ;)

My power supply is a Bestec ATX0300D5WC. It's what came with my HP Pavilion p6310y, which I got about four years ago now. The CPU is AMD Athlon II X4 630 2.8 GHz. I did make a phone call to EVGA support and the support technician told me that the box information hadn't been updated, and that the 300 watt minimum is correct. He didn't ask me for the specific model of the 750 Ti (it's the 3751-KR), so there may of course be room for error there. On Newegg's product page for the card, I was able to find people referencing the need for a 400 watt power supply from back around February/March. Before finding those comments, the only thing I'd seen stating the need for more than 300 watts was the box itself. I just wish I could find something stating the reason for the apparent change from 400w to 300w, for peace of mind. patta016

That's reassuring, since my PSU seems to be roughly the same as yours, but with 19 amps on the 12 volt rail. On the other hand, I bought this card to replace a GTS 250 that was foolishly used in this same PC. Evidently that card required a 450 watt power supply, and while it worked great for almost four years, I'm pretty sure the power supply was one of the reasons it failed (there are probably two other reasons, but they're even more embarrassingly stupid errors on my part).

I think it should work fine though, the max draw on the card is only 60w (5 amps). This shouldn't stress the psu. However, is your motherboard's bios up to date? I've read that there are some compatibility issues if its older.

The card will work perfectly fine with a 300 Watt PSU, this is due to the card only drawing 40 or 65 watts as a maximum (Cant remember which one of the two it is). Though I think that I should warn you that if this PSU you are using is bad quality it might not be able to supply the full rating that it lists on its case. This can cause one of two problems, for one if you have a lot of other devices connected you may reach a point where the computer will just shut off when running a demanding application. Or here is the more damaging end result the power supply may become overloaded and will simply destroy itself and everything that is connected to it. That is why board partners overate the power supply they recommend as to possibly compensate for bad quality PSU that will be out there.
For example, I have a 620 Watt PSU that can provide that level of power output for 24 hours a day for the 5 year warranty period. And here is the funny part even though my GPU recommends a 600 watt PSU my system only fills 250 watts even under 100% full load.
I hope this will help with your situation.

After release, Nvidia went back and revised the power requirements for the entire 750/750 Ti line. This also applied to cards that had already shipped, which is why the boxes haven't been updated. The cards didn't change, nor did Nvidia suggest building them differently; only the power requirements changed. For most systems, a 300w psu should be sufficient for these cards. The only model that would require a different psu is the 750 Ti FTW, which requires an additional 6-pin connector.
The only concern I'd have with your system is that a lot of the HP Windows 7 systems seem to be unable to recognize 700 series cards, such as the 750 Ti. If you're not using an HP, then you most likely won't run into any trouble.

Interesting. Must be an OEM thing, in that case Zatunks be sure your motherboards bios is fully up to date. Luckily I haven't had any problems using my 750ti in a old Asus P5n-D, pretty sure it has the oldest bios on it. How old is that Bestec unit though? Never mind you said around 4 years ago. Personally the next part you should consider buying is a newer more efficient PSU for your system. As time goes on your power supply has aged so it isn't outputting the same amount of wattage it was, and if you ran a GTS 250 on it prior it could of stressed it a bit more then needed.
I will either find a way, or make one. ٩(๏̯͡๏)۶

Yeah, it's an OEM thing. BIOS update won't help those specific systems, unfortunately.

This is my concern now, since I ran across that subject while researching the power supply issue. The latest BIOS update available for my HP is from June/July 2010 and it seems the chances of that being a fix for that potential problem rely a bit on the BIOS update being released more recently. It seems that whether the card will work on my system or not is an unknown until I simply try to install it. I guess that means the card's got to go back, since I'm not willing to have a $130 paper weight in the event that my system won't recognize the card. It's frustrating, because I only bought this card because I thought I had what it required and that it would be an easy and reasonably inexpensive way to just regain access to the games I've already bought for my PC over the years. I definitely wasn't looking to do a full system upgrade before my old card failed, but I guess that's what I'm looking at now if I want to ever play those games again. Thanks, everyone, for the input and advice you've given me.
