Card was DOA. Will it run on 425 watts at least temporarily (fans work after I installed it) It has 2 power supply connections do I need them both?
1836703
both connections must be used, I had mine limp along for a couple of weeks on a 350 watt ps, though not recommended.
1836704
sure you need them both, AMD recommends a 500watts power supply or greater to run this card so if i where you i wont do any risk
1836705
yes you need them both, and i highly doubt that it will work with only 425, maybe thats why you think is DOA.. you need a minimal of 500W, this is a mid/high end card, why would you only use 425W to power your ENTIRE system when this card uses around 200 or 300 (cant remember) Watts...
1836706
425 watts is really pushing it. To help you decide google a power supply calculator and factor in everything in your system, including the case fans. Yes both power supply connections need to be plugged in for proper function. I don't know what's in your system but I'd recommend upgrading your power supply to at least a 500w. Cooler master makes a good one for a good price.

You need to use both power supply connections and you would probably need a power supply rated at least 550 Watts (card alone is rated 175 Watts not including any other part of your system.

It may run on a 425W PSU but it will run sluggish. Yes the card requires you have two 6-pin connectors hooked to it to run properly. It will run properly if you upgrade the power supply. The card requires a minimum of 500 Watts, but my suggestion would be to go to a 550w at least or a 600w PSU.

It won't even come awake without plugging in BOTH power supply connections. That may be the reason it seemed DOA. When I got mine I upgraded my Power Supply from a 425w to a, new, 750w. I didn't try it with the old supply, so I am not sure if, or how well it might run with the 425w. I think it will highly depend on how many other items are sucking down power and the requirements for those units.

No, the card must have a minimum of 400 Watt power supply. The card alone uses 110 Watts. Source: http://www.evga.com/Products/Product.aspx?pn=01G-P4-3650-KR#

You should be OK. I just built a steam machine with a 430w PSU and I'm running this card just fine!

According to NVidia, this card pulls 49 watts. It does not have any 6 or 8 pin power connectors. As long as you have at least a 300 watt power supply, it will be fine.

The wattage of the card is 95WI would double check your wattage but just from that info I can calc 404w for the full system.I would look into getting a larger PSU. I always over shoot my systems on wattage.

Yes. I am running it just fine off a 650W PS. Make sure its a decent quality Power supply though.

I had a 350w with no problems. Depends on the CPU your using. I had an i5-660 with 4GB Ram. This card uses about 80-90 watts at full load.

I have my whole system hooked up to a 750 watt PSU except for my second card, which is hooked up to my 500 watt PSU. So if you're putting both cards on the 750 watt PSU then you should be fine.

A power suppuy with 600 watts will be enough, make sure it has 2 pci express of 4 and 8 pins, and remember to be sure its compatible with your motherboard

I would suspect that if you're replacing a prior card in your system, your power supply will be adequate. This card does not require any additional power cable to be attached, it gets all its power from the graphic's slot. I would imagine if you have over a 300W power supply you're OK.

Nope. On the box it says a minimum amount of power to operate properly. I think a 350W power supply is not sufficient to run this card. Plus, you will need extra 2 peripheral power connectors if you do not have a 6pin power connector to the PSU

I dont know my PS is 650W it has the proper plugs for the card , in fact another set of plugs for another card as well. Works fine :)

You will want a 500 watt power supply min if your running 1 card. I do not have a program to test the power consumption it dose take a single 6 pin.

This card has a TDP of 115W, thus a PSU of at least 450-500W* would be recommended, leaving some wattage for other components and upgrades. *Standard PSU warning: Watch out for outdated and/or mislabeled PSUs (such as this one: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=324 ) - some PSUs do not deliver their rated voltage, or are rated on their 'peak' output wattage (the wattage they can provide for ~10-50 milliseconds before catastrophically failing)

I paired this card with a 400 watt power supply, and that's about as low as power supplies go. So I'd say you're safe with at least 400 watts.

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%.

Depending on what else you have, and if you over clocking your CPU or the GPU it won't work. 750W is your best bet. I'm stuck in the same boat as you cause I'm trying to buy two but it won't work but I'm not trying to buy another PS
