How do I power a dGPU with a SATA power cable?

[Tarun10]

I have a really dumb prebuilt system with some random Socket 775 Pentium Dual core and an Asus GeForce 210. The rest of the specs are pure shit.

I just want to do some casual gaming and maybe get a GT 1030/GTX 1050TI(if prices drop) in there... but the problem is the Power Supply is just made by a local brand and there is no PCIe power connector. All the connectors are used up except for two SATA power connectors.

So, is there any way that I can power a GPU such as the 1050TI with two SATA power connectors and adaptors or is the power just insufficient???

Not to mention that I don't know the Wattage of the PSU.. I think it's 400W.

Should I just get myself a Corsair VS450???

The 1030 doesn't need a PCIe power connector, it gets all it needs from the motherboard.

Thanks but I am hoping to wait for prices to drop and maybe wondering if I can afford a 1050TI??

Same situation, only uses slot power except IIRC for some higher end models.

 

Either way, unless you like to play with literal fire then don't use a molex or SATA to PCIE adapter.

You can get 1050Ti's that dont need a 6-pin as well. Though I'm skeptical whether it would be worth putting one into such an old system.

Thanks maybe I will just upgrade my whole system..

Thanks again maybe I will just upgrade my entire system within a year or so...

the real question is what wattage is the power supply and who makes it.

i have done that mistake of running a powerful card (9600GTX at the time) with a cheap power supply thats provided with these pre-built systems and the PSU just went bang when i was playing BF3, im lucky it didnt take anything with it.

 

now i use a Corsair CS550M which is a 550W Gold rated PSU which i bought a few years ago for £50 from ebuyer, im still using it today with my phenom II 1055T and GTX970

Thanks. It is made by Zebronics(heard of it???) and I think it is either 400/ 350 Watts. The whole system cost 150@ so I can't expect a good power supply.

nope never heard of it. lets say your PSU is 400W and is 80% efficient. it would mean the toltal out put of your PSU is 320W, but most PSU's lose about 5% of there efficiency every year so your actual output might be a little under 300W, having a more powerful card might work but the PSU might not be able to run it for a long time.

 

it might be worth buying a PSU from a known brand like corsair, 500W should be more enough just make sure it says its at least 80+ bronze rated (mine is gold rated meaning its 90% efficient)

That is not quite how efficiency calculation works.

 

If the PSU is 80% efficient, then if it was outputting 400W, it would really be pulling 480W from the wall socket.

20%, or 80W, will be wasted as heat or other forms of losses.

 

Example:

Corsair HX750i

821W pulling from the wall as AC Watts, and the result is 742.6 DC Watts = 90.5% efficient

DO NOT attempt to power a GPU off a SATA connector on a cheap PSU. It will not end well.

Looks like you have a system that is almost 10 years old. I would say it has reached the end of its lifespan. I wouldn't waste spending $250-$300 on a new graphics card and another $50 on a new PSU to upgrade it.
You could spend the same amount of money upgrading to a new system with inbuilt graphics with AMDs new APUs and see a benefit over your current Pentium system. It would probably even out-perform your Pentium with a 1030 graphics card. Should be fine for casual gaming, as long as you don't mind playing at low settings 1080p or medium 720p and aren't too concerned about hitting 60fps in triple A titles.

AMD 2200G = $100
Motherboard = $50
RAM (1x8GB) = $100 _{(Though I would definitely recommend 2x8GB sticks for $200, especially as it needs to share memory with the graphics)}
Power Supply =  $50
Total: US$300
_{(This is assuming you can re-use things from your current PC including the monitor, case, keyboard, mice, storage drives & operating system, etc)}

Once you save up a bit more look at upgrading by adding things such as an SSD and a discrete GPU such as a 3gb 1060.

Wattage + manufacturer makes zero difference

Nope, the 400W output would be 80% of what it takes from the wall.

 

Brands make zero difference. 80+ scores make zero difference. There are some 80+ Platinum units worse than Bronze units.

So you are saying that anything from the Manufacturer is not believable and that I should check specs and then decide without the efficiency rating.

Also what if the rated wattage was the input into the PSU from the wall then a 80+ Bronze rated 500W Power supply would deliver 400W right??? However if the rated wattage is the output then your argument makes sense.

Some is believeable some isn't. But generally you have to check reviews.

 

There's a tier list in my sig that makes PSU choosing easy, you should check it out

The 500W is a continuous output rating on most trustable units, but there's always the generic no name so...

Thanks for the info. So I should just check Johnnyguru before buying a PSU?

I bought it almost 3 years ago but since it was prebuilt I think they just used the oldest parts available. Also you can't really expect anything fancy and new in India at least not at a good price.

I did plan on a cheap system but the cheapest RAM from a reputable brand is at least 110$, the cheapest 450W PSU is almost 75$. The H110M motherboards are 60$ and everything is almost priced higher by 20%. As for the CPUs, the Intel side is okay but the cheapest i3's are almost 150$ and the Ryzen side is limited with only one option each in the Ryzen 3, 5 and 7 series. The cheapest is I think almost 130$(Ryzen 3 1200, I think). The AM4 motherboards are at least 100$.

Not to mention the case I have is shit, worse than the stuff on Scrapyard Wars and the only ones available new on Amazon are the Corsair Carbide series and a few NZXT ones out of which the cheapest is 50$ but really old and any decent cases are at least a 100$. Peripherals' prices are getting better thanks to amazon but still are limited. There are only two or three e commerce sites which sell this stuff and local stores just slap on mind blowing prices with brand names.
So for the foreseeable future I think I will just dump this system and hopefully some of the prices drop soon.
