HP Compaq 8000 Elite power supply upgarde

Okay, so you have some time still.

If you pull the side of your case off, there should be a sticker on the power supply telling you how many watts it's rated at. My assumption is that it is high enough that you would be able to simply install a GTX 750 ti (I'm not sure what you mean about it being used) and you would be on your way playing games at a decent resolution and quality. 

If you go through with modifying the wiring to accept a standard power supply that is rated for more watts, then you would be able to run a more powerful graphics card. 

It really comes down to how powerful of a system you plan on building and how much you are willing to spend. If you could answer those, that would help us figure out the best way to help you.

It's hard to say how much it would cost. I did something similar to what XargXar did, only I soldered all of the wiring myself instead of using the splicing plug thingys that he (or she?) used. For me, all I needed was a 24 pin extension and the voltage booster, and that cost me maybe 10 bucks in total. I don't know how much the splicing plug thingys are, and I don't know how much someone would charge to perform the service for you.

Does that help at all? Let me know if something doesn't make sense.

Here is a 750 ti on Newegg. While it's not the cheapest 750 ti on the market, it's one of the most popular variants, and EVGA is a fantastic brand for GPUs.

In the specs list, it says that the recommended minimum power supply is 300 watts, which your computer should easily have just the way it is.

I have to buy 750ti if i cant get wiring for 500psu......if someone will do that for me than i have a bugdet of 150$ for gpu....

Please bear my noobness 😞
How much time will spent on wiring so i can guess about technician cost !

Someone said in upper replies that voltage boosters are not right solution . Is it ? How much you used ur pc after wiring thing.......any problems u got ?

Okay, good to know. So even if you were able to get a beefier PSU, the best card you'd be able to afford would be something like a GTX 950, which from my understanding is better than a 750 ti by something like 10 to 20%. So not HUGE gains, but a 950 would be better if you could swing it.

Honestly, I think it's a bit of a crap shoot when it comes to using the voltage booster. It seems like XargXar has found a setup that works well, but in my system, I'm having the issue of the computer not even wanting to turn on 80% of the time. I honestly think it could be that my PSU isn't very happy with this setup, but I'm not super sure. So basically, using a voltage booster and modifying the wiring is a gamble (at least in my experience). This is in large part why I'm pushing the 750 ti so much, because you could get around this whole PSU mess.

Another option is to buy a new motherboard that supports your processor's chipset (which seems to be LGA 775) and then you would be able to simply plug in a more powerful PSU and install whatever GPU you wanted.

While it's not SUPER cheap, it probably would cost more than half of this motherboard to have someone else do all of the wiring and stuff to TRY to make a different wiring solution work.

This motherboard should work assuming you have a micro ATX (so normal size) mobo/computer already.

In the end, I'm not going to tell you what to do with your money. I'm just trying to give you as many options as possible. 🙂

Xargxar didnt mentioned his psu also 😞

Thing is, especially with older harware like what we're using, you start running into dimishing returns really quickly.
So for $130 or so dollars, you can buy a 750 ti, plug it in as is, and be good to go. And maybe use some of the extra funds to upgrade your ram or something. Once you start getting into the territory or needing to buy a new power supply and either a new mobo or having someone piece together a wiring harness that might not even work right, all for a 15% gain in performance, you really have to ask yourself if spending another $100 bucks is worth the extra 5 fps that you'll see.

I have also old hardware as u have bro !

Xargxar wiring will not be working 100% perfectly ?
