[SOLVED] Is Fujitsu 250W 2 x 12V Rails 15A enough for GTX 1050 Ti?

Dear Sirs,

I have the Fujitsu Esprimo P520 system running on 250W Proprietary Power Supply with 2 x 12V Rails 15A only capable to supply continuously 250W (max 17A 280W for 15 SEC) at peak. PSU Model is D12-250P1A (S26113-E5611-V70-1).



I have currently Intel Core i7-4770, 1 x 8 GB DDR3, DVD-DW, Samsung 500GB SSD and GeForce 1030GT (purchased separately to P520 system). Is it worth to purchase GeForce 1050 TI instead without 6-Pin to run on this power supply? Officially recommended is 300W. I clearly realize that power consumption of the whole system should not exceed 200W, but is it worth to risk with such configuration?

Please advise. Thank you in advance for your opinion and comments.

The 1050ti only requires power from the PCIe x16 slot, so ~75W is the maximum it'll draw.

The whole system will draw under 200W indeed during intensive stuff.
That PSU will output 15A on each 12V MAX... that means that when one of the rails is fully loaded(15A@12V) the other will only be able to supply somwhere close to 5A only... that's because the MAX power output is 250W.

Overall, the 1050ti will probably work on that PSU, but keep in mind that's not the greatest unit. I see that's proprietary too as I see it having a 16pin connector for the motherboard power... you're basically stuck with it considering the form factor too.

I'll give the green light on this... just keep in mind that a 1050ti is the best you can upgrade to on it.

Thank you for opinion. I decided to check on practice how much system consume.

I recently ordered the following device https://www.amazon.de/dp/B007459MH6 and measured power consumption from outlet.

I generated load using FurMark Burn-In Test + Prime 95 in Small FFT mode simultaneously. Device showed me 152W under such stress load. As I understand I can deduct about 20% effeciency losses = the factual load on my power supply then 121.6 Watts. My videocard is 30 TDP, GeForce GTX 1050Ti maximum 70. I add difference on 152W - I get 197W load under stress load.

Is my assumption is right?

I made another measurement with Furmark Burn-In Test + CPU Burner with 8 threads running in parralel - I got 123W. In case I use instead of Furmark CPU Burner Prime 95 with Small FFT - result is 156W. Please find result attached. Also want to note that now I have 2 x 8 GB RAM in the system, here is difference in 4W from previous measurement.

Did you test with Prime 95 small fft with AVX disabled?... If you did it with it enabled, the test puts an unrealistic load on your CPU.
@ChumP, no AVX was enabled. With AVX2 / AVX checkboxes disabled result of measurement is 130-132W. 7W difference to Furmark CPU Burner.
