Will a 250 watt PSU support a GTX 750 (non-ti)?

[zdragon053]

I have a HP pavilion P6000 that I bought awhile back. 250w power supply, 4 gigs DDR3 ram, etc. I heard from a site that the components all together (cpu, hdd, etc.) take up about 160W. The GTX 750 uses about 55-75 watts, which would leave me with about 15W left over if the GTX 750 was being used to the max. I only plan to run games on low at 1024x768 (which is the highest my monitor will support :/) so hopefully it won't be working that hard.

take a look at this video, and focus on the lenovo system:

(also, ignore that is a 750 ti, every time they say 750 ti, think they said 750)

that system has a 250w PSU, and the GPU runs fine.

can you tell us the exact model of your pc? HP's website says 128 models available.

as for the psu, OEM pcs come with psus that are capable of running the prebuilt parts alone and not much more.

a power supply upgrade would be a good idea.

Every GPU has a self check that detects "Does this system have enough power for me" If you do not meet that your system wont even boot up, will a 250W work? Possible but another question is for how long will it work, Lenovo isn't exactly know for using high end parts. When you compare a cheap power supply new and used your going to find out that after even two years they output less than what they did. A Cheapo 250 W after a period of time might output as much as 15% less or more and fail to boot with a GPU that ran it @ 80% new. I have come across this many times with repairing upgraded Branded PC's.

Your option of try because nobody on this Forum can give you a positively Yes answer based on Theory craft when you do not know the quality of the parts at hand.

You cannot compare a pc with a 55w cpu with modern components compared to his with a 95w cpu and 5 year old components. Psu capacity lowers over time and you aren't going to have the quality like many of today's prebuilt that now have bronze psus. You usually want to stay below 80% of the total capacity to not overwork it and cause a premature death. But what's more important is the 12v amps. You could have say a 250w psu when it can only do 100w on the 12v and the cpu and gpu use that. Then it just shuts off every time you play a game.

I would recommend buying a new psu, here's a $25 one that meets your needs

same platform, better design, barely higher price than the w1. amusingly it's got the same price as the w1 at newegg.com.
both are entry level psus btw.

Good suggestion but it will cost him $40 upfront make sure people are aware of Mail in Rebates and Shipping costs.
