The Official PC/Computer Thread

Looks like you have a in-board video card. You need to first confirm if you have a open PCI-E slot for a video card.

that 4.7 GB of ram tells me you aren’t getting your full ram, as part of the ram is partitioned off to your on-board video.

Before we start shopping for a video card, how much are you willing to spend?

Right now I have $300 my job has been slow lately

Well there a decent selection of $99 to $300 video cards for both AMD (formerly ATI) and Nvida cards.

I am happy with my Radeon HD 7770, which is around $100-$150.

I do suggest doing some of your own research between AMD and Nvidia
Also factor in your current Power Supply, you stock Power Supply may not be adequate to power your new Video card.

Also check to see if you have a open video card slot.

yes the pc has a PCI-E slot available

this is the current PSU in the pc

Fromt he link you provided

Yeah, take note on the power requirements on your replacement video card.
As 250 watt power supply isn’t going to cut it.

Like the card I pointed out had the following requirement

So I factor cost of a good replacement PSU.

thanks Darksakul i’m going to check my local electronic fry’s before checking online

Im not sure about this, but the new gtx 750 ti for $150 uses only 60 watts and you might be able to use it with your 250 watt psu, can someone confirm this? But you should get a better psu just to be safe.

I’d need to know the TDP of the system to be sure, but I don’t think it’d be an issue.

Honestly though, I’d buy whatever GPU you want in your price range and spend the $20 extra on a Corsair CX 430 Power Supply which is more capable of delivering it’s rated power(and then some, if you really wanted to do so).

EDIT: What is most important, is not the recommended value specified by the manufacturer(because it wants to ensure there will be actually be enough power, even on inappropriately rated PSUs), but the TDP of the device. GPUs draw power from three locations. The Motherboard(up to 75W according to PCIe spec), and 75W additional power for each six pin connector(and 150W for each 8 pin, but they are less common now).

I looked it up and check several different brands Asus, Pny, EVGA, MSI and Gigabyte.

The Pny, Gigabyte and EVGA states they need the PC they are installed with to have a minimum of a 400 watt PSU
MSI gtx 750 ti requires a 450 watt PSU
The Asus does not give a minimum PSU rating but the card draws on its own 150 watts

Stier needs a new PSU, any ways the PSU that come with off the shelf PCs are cheap crap any ways.

Sources from from each brand’s respected site.

I would play it safe and go with a 500 watt or higher PSU. Although that PSU is nice.

so i might just choose between this ASUS HD 7770 or the Radeon HD 7770 that Darksakul linked

Not sure if question goes here, but…
Does anyone know of any good Composite cables to HDMI converters?
Trying to hook up my PS2/Dreamcast/old consoles into my LCD monitor.

I recently used the EVGA GTX 750 ti FTW ACX in a build with an Intel i3, Mitx motherboard, 1 SSD, and 1 hard drive, 3 fans, and cpu water cooler. The most it only used 180 watts total while playing Battlefield 4 at 1080p high settings. Check out the vid I upload using Shadowplay from Nvidia

The actual gameplay onscreen looks much better than the compressed mess youtube makes it out to be!!

The 180 watts is just the video card, you also have to factor in the rest of your gaming rig as well for your PSU.
It is a pretty common occurrence that when you put a new Video card into a PC the PSU will also need a upgrade.
Especially if the PC is a off the shelf Computer from a retail store.

For the PC I mentioned, it was 180 watts total from the wall, for the whole system. The video card by itself is just 55 watts.

I want to call shenanigans on this.

EVGA GTX 750 ti according to EVGA’s website recommends a minimum of a 400 watt PSU.
Every other manufacturer has the same or greater requirements for the GTX 750 ti.

Unless you have actual test data proving your whole PC only draws 180 watts from the outlet (preferably results we can review and duplicate), I will ask to to STOP NOW.

Also please factor in the total wattage required is not taken when the PC is idle, but under a full load where CPU and GPU working at (or near) 100% capacity.

Here are a couple of reviews of the Total sytem power usage for the GTX750 Ti

Here is one where some cryptocurrency miners measured the card on its own.
cryptomining-blog.com/1141-a-bit-more-on-the-actual-power-usage-of-geforce-gtx-750-ti/

The 180 watts I got was while on full load playing Battlefield 4 at 1080p - High settings

My nephews have the 750 Ti right now, so I can’t run tests for you right this instant. You would be surprised at how much some manufacturers over estimate there PSU requirements. My personal rig has an i7 3370k overclocked to 4.4 ghz, 2 Radeon HD 7950’s overclocked, fullsize ATX motherboard, 2 water pumps, 2 SSD’s , 2 HDD’s, 9 fans, and a 2 meter LED strip…Has never broken more than 600 watts TOTAL!

I like to note that your Bit-mining article, many commentators still question the validity of the test results.
And they share my opinions on the matter. (also bit coin isn’t legal in the US but that off topic)

Also regular game play (even on max settings) is a horrible way to test wattage use and system stability under a load

You 60 watts is still not under full load, and is still testing the PC at ideal conditions.
Rarely you are going to get those ideal conditions every single time.
What you think is wasteful I find precautionary, you are tricking your self to thinking the bare minimum PSU will be enough.

In more ways than one a good PSU is the most important part of your PC.

My approach is considered OLD-SCHOOL but offers much more accurate results.
I prefer the Burn Test, run the system at 100% capacity and record/monitor for system errors.
Those Errors point to system instability and later on system failure.
Example how a Burn test would be done.

Also please factor in that whats on Paper on a PSU is not what you are going to get.
As your systems goes to higher loads (even with a excellent cooling system) there more heat that being produced.
Every part in your PC starts to under-perform as that heat rises.
Its why PSU are rated as 85% efficient instead of 100%

Under a Full Load that (on paper) 250 watt PSU becomes a 212 Watt PSU.
And in any electrical system, when you under watt complex electronics bad things can happen
Such as a catastrophic cascading-system failure.

Manufacturers don’t just post that their Video cards need a 400 watt PSU for nothing even if the card idles at 60 watts, 97 watts playing Over-hype-FPS-the-game at max settings.

Also part of my point of recommending the PSU replacement as the stock PSU from pre-built off the shelf PCs are mediocre at bests.

Take this however you want! How about you build a system like the one I mentioned before and see for yourself. Also, I’ve yet to say not to upgrade the PSU to anyone on this thread. Someone asked a question about the 750 ti and I answered with my personal experience on that card. The stress test you linked is fine and all, but those tests can only be run one at a time. If you run Prime95 and a GPU benchmark at the same time, the GPU will not run at 100%. Memtest can only be run on it’s own. Once I get that card back I’ll post a vid showing the total wattage. Until then, I’m done with this conversation because it’s not gonna get us anywhere.

I’m sorry to say that while Scabby should buy a better PSU, you are incorrect about efficiency effecting output. PSUs are rated for their output power, not their input. So, at 85% efficiency, a proper 250W PSU outputs 250W, but draws closer to 300W from the wall when doing so. This is the standard used to rate all ATX power supplies.

That said, there are many PSUs that can’t do what’s advertised(particularly if they don’t come from a “Big” brand), and indeed should be replaced. 250W is awfully low and leaves no room for expansion, so I’d pick up something newer anyway.

Just put this together right now for testing:

Intel i5 4570
MSI B85-G41 motherboard
EVGA GTX 750 Ti FTW ACX
Team Zeus 8gb 1600 Mhz RAM
Corsair H60 liquid cooler
OCZ Vertex 4 128gb SSD
WD Blue 1 TB HDD
Corsair HX750 PSU

Wattage measure with a Kill-A-Watt meter

Not the best production…lol. It’s late and I’m sleepy! Ran Prime 95 and Unigine Valley to stress both CPU and GPU. CPUZ and GPUZ open so you can see clock speeds for the CPU, GPU, and RAM.
