Is 300w enough for this graphics card?

Yes. 300W is the recommended PSU Wattage for the Gigabyte 1050 Ti Windforce OC.

Yes, 300W is enough power for the GTX 1050Ti.

Whats the make and model of the PSU? It may not be able to deliver anything close to 300w where it counts on a modern system. Does it have the required 6-pin pci-e power connector for the card? System specs? The gpu isn't the old part that requires power without the full specs total power draw is an unknown.

EpIckFa1LJoN · Jan 19, 2017

bignastyid :

If its rated for 300W surely it is capable of powering the 75W GPU.

You know WHY they recommend 300W supplies even though the GPU will never come NEAR full draw? That reason exactly. Even a budget 300W should power a 75W GPU. I will grant you that yes he still will need the proper cabling, but there's no reason a perfectly functioning 300W PSU will not deliver enough power to supply a 1050 Ti.

EpIckFa1LJoN :

There are many junk/cheap PSU's that can barely deliver half of their worthless overall rating on the 12v rail. Modern systems get the bulk of their power from the 12v rail. Some of the 1050Tis that are factory overclocked and use a supplemental power connection(like the one in the OP's link) can use ~80w. So pair that with a cpu and motherboard that use ~100w from the 12v rail and you are already meeting or exceeding the 12v rating of many cheap 300w PSUs, which is a recipe for disaster.

This is WHY you should get more information on the system and PSU before telling someone they are fine. There is simply not enough information in the post to give the OP a proper answer. Which is why I asked for more.

The [dangerously] short answer, is "Yes, a 300W PSU is enough for a GTX1050Ti." The long answer is based on what bignastyid posted. Just because a device has a "300W" label on it, does not mean it can actually produce that, or produce enough of it on +12V. If it's a quality PSU like a Seasonic, you'll be fine. If it's a Logisys, Diablotek, Apevia, or other PSU-shaped object, the answer may be "no," and finding that out could be destructive.

It should be helpful as well to see how many amps it can deliver on the 12v rail. A good brand, as has been discussed, also helps.

Quality over quantity.
Remembering back to a big PSU roundup review 12-14 years ago. A couple of the 300w PSU, like Fortron, were able to sustain over 500w. Couple of the cheap 500w units petered out below 250w.

@ EpIckFa1LJoN, please do not choose the best answer in any thread that is not your own.

Dark Lord of Tech · Jan 19, 2017

EpIckFa1LJoN , don't select solutions in threads that aren't your own , the OP will choose when they are satisfied with a response.

Thank you.

Even with a crappy 80% efficiency power supply, any 300W is more than capable of powering a 1050Ti. They are very low power. You would have to search hard to find a 300W power supply incapable of powering it and have a very elaborately inefficient PC component setup for it not to work.

Onus · Jan 19, 2017

There are PSU-shaped objects out there with labels that claim they are able to provide 550W, that will choke, smoke, and croak if you try to pull more than about 250W from them. It's a shame that consumer protection laws in the US don't seem to extend to PSUs, but that's just how it is. You need to read competent technical reviews (which include load testing and teardown, not just "I attached it to a PC and it worked") and learn about the manufacturers before making blanket statements relative to claimed wattage.

Efficiency only determines how much the psu pulls from the wall not how much it it can deliver to the system. And finding a craptastic 300w PSU is not hard at all. There are scores of generic rebrands that only have 15a(180w) on the 12v rail. A 300w Codegen and an Aopen that have 13a(156w) 12v rails. For OEM PSUs HP has a bestec made 300w unit with a 15a 12v rail, that unit is also used in some E-machines. These are just what I found in a few minutes on ebay and google searching for 300w ATX.

Even with those power supplies they both supply more than double the consumption of a single GTX 1050Ti on the 12V rail... The TDP of a 1050Ti is 75W. The only thing that would allow this not to work is a CPU with a TDP over 75W and of course, a crappy power supply.

Susquehannock · Jan 19, 2017

Yeah. Crazy how PSU are not properly regulated. And even a crappy PSU would be expected to power the whole system, not just the 1050. Have seen some with wires of small gauge as to only be trusted to power an LED or two.

You seem to forget the PSU has to power MORE than just the GPU, it has a cpu, motherboard, possible an optical drive and hdd(s) that all use the 12v rail and currently we have NO idea what else it has to run. In my post earlier I posted and example. 80w for the factory oc'd gpu and 100w for the rest of the system so 180w pull on the 12v rail on a psu that may not be able to provide that, and even if it is rated for 200w if its a low quality unit running it at or close to its max is a very bad idea.

Yes the TDP of a STOCK 1050ti is 75w the after market overclocked version come with a 6-pin connector because they use MORE than a stock card. And look at that the card linked in the op is factory overclocked and has a 6-pin connector for when it needs more than 75w. Some factory overclocked 1050Tis pull around 80w under full load.

I had previously edited my text about the CPU being a possible contention.

Is 300w enough for this card?
