Power Supply and Graphics Card

[SaintK]

I'm not sure about the model of the source, and I'm also not sure if the source I have is of good quality, I only know that it's 300W.

I've looked around here and I think the prices of these cards are not very high, in my opinion they are quite good, of course, depending on where you buy them.

Thanks for the help ^^.

If your power supply is like the one in the image:

You need another one that's better to sleep peacefully :sisi:

Ask for one that's 550/600W and with "80Plus" certification, so you can be sure of a minimum quality of manufacture. If the Thermaltake they offer you is at $80, probably what I recommend will be around $100, but if you're not convinced by what they have, buy the Tt as the lesser evil.

About the graphics cards, as fjavi points out, you should try to get up to an HD7850, but if not, an R7 260X (HD7790) will do the job.

This is a photo I just took of my source, it doesn't seem to be the same as the one you showed.

You have an improved version of the one I had, and I'm glad, because the other one had an efficiency of 65% :facepalm:

In any case, to put a new graphic, you will have to change to a more powerful source.

Salu2!

Okay, so that's what I'll do, because I don't think a 7790 plus the whole team will move with 300W.

Thanks again ^^.

You have nothing to lose by trying, plug in the graphics card and if the computer doesn't shut down when you play, it can power it, although it's never recommended that the power supply works at full load, as it could break important components, if that power supply were quality it could easily, but being generic they don't give the real power.
A good 350W ensures 350W sustained and at 50º temperature and could give peaks of 450w but the generic ones don't guarantee the sustained watts, we mean that a quality one should ensure its power even with a lot of heat it should never go below that power, that's why it's normal for them to give a little more, but the generic ones do go down and don't give stable voltages that's why the graphics cards can't handle it and are also not good for OC.
Anyway it's good to buy a quality power supply, as they usually last a long time and are cost-effective, I have power supplies that are 6 or 7 years old and they still work perfectly, although the one with the least power is 700W a seasonic.

And in the photo I posted above, how can I know that this power supply is generic or of poor quality?

In the Cases and power devices subforum, you have several specific posts that can help you learn more about power supplies:

Well, I already bought a 7790 with 2GB, a Themaltake TR2 600W power supply and a Logitech Gaming Keyboard G105. The 7850 was impossible to get, and the GTX 650 Ti BOOST also, and as for the power supply, it was the only one I could get, apparently around here they only sell the TR2 model and the SMART model, but the latter at double the price of the TR2, so there was no other choice. My sister gave me the keyboard, and it looks nice.

Then I managed to connect the power supply (It was the first time I did it), but a couple of problems arose, the first one, I had no idea that I was going to need some "pink cables" that connected to the motherboard with the DD and the DVD drive, initially I believed that those cables belonged to the previous power supply, but when I saw that when I turned on the PC it automatically entered the BIOS, I had to connect them.

But the real problem arose after, it turns out that I connect to the Internet through a "network card" that occupies a slot next to the PCI Express x16 where the graphics card connects, therefore with the network card on and the size that the graphics card occupies it is impossible to connect both at the same time, I already said that the fact that they occupy "double space" was important. So, either I connect to the Internet or I connect the 7790, a dilemma. I think the only solution is to buy another network card but that connects via USB, since my motherboard only has these slots:

º 1 x PCI Express x16 Gen2.0 slot
º 1 x PCI Express x1 slot
º 1 x PCI slot

I continued, I connected the graphics card to test it and such, I installed the drivers, and everything seemed normal, but here comes my question Is it possible that my PC accepts two different graphics cards just by restarting the PC? Because at no time did I uninstall the drivers of the Intel HD 2500, although when I was using the 7790 these disappeared from the taskbar, and as soon as I disconnected the 7790 and went back to using the Intel HD2500 for the Internet issue I mentioned above, the drivers of this integrated one came back, and it works correctly, and the ones of the 7790 are still installed too.

Another thing, while I had the 7790 in my PC I tried some games, these worked at Native Resolution in High at 60 FPS because of V-Sync, something that with the Intel HD2500 was impossible to achieve, so I assumed that the graphics card was working correctly, although I don't know if it had the latest drivers installed, because of the fact that I installed the ones that came on the disk, for not being able to use the Internet. What I didn't like at all was that at a certain moment playing COD 4 (I had been playing for about 5 minutes) the computer froze for about 15 seconds and when it came back the FPS dropped to half, I quit the game, tried again and the same thing, at 30 FPS, I tried another game that was running at 60 FPS and the same thing, they were at half, I don't know if it had something to do with using the overclocking tool that came with the 7790 driver and I raised the GPU frequency to the maximum, maybe it overheated or something. I removed it and went back to using the Intel HD2500, with which I am right now while I buy the damn network card. The question is, Did I mess it up? I think that if it had been a power supply issue my graphics card would have burned and my screen would have gone black, I hope it wasn't something I have to worry about.

It's not that you have two graphics cards at once, it's that when you put a dedicated one, the integrated one disconnects, then you say you use a network card but your motherboard must have integrated network connection, if you mean Wifi you could put a USB card, but the best thing is to connect by cable with the RJ45 that your motherboard has. Then your power supply looks generic because of the type of cables, without sheathing and the casing looks like the power supplies used by OEMs or assemblers of equipment that are usually cheap and bad power supplies, that's why it's not recommended to buy assembled equipment, you can always build your own one much better and even if you look at cheap components, they are sure to be of higher quality than what you buy assembled, maybe it costs a little more but they are much better equipment, you can choose from many components, you will have a warranty for the motherboard, CPU, memory and all the components you put on it, plus the manufacturer's warranty, they are usually more reliable and durable those equipment, many of the assembler's boards are cut from bios, from extras, that's why they sell them cheaper, they don't have the same support that the manufacturer gives. Then if you did OC to the max and it crashes remove the OC put the Msi afterburner and put the default configuration restart and it should work again, the OC is done little by little, and if it's not stable then it's lowered, but pushing it to the max can make it perform worse and more ups and downs that is if it doesn't crash and restart the equipment, I think in AMD when you start it still leaves you the OC and what you should do is reset the frequency so that it goes to the factory frequency. regards

Your motherboard must have an integrated network card (look at the rear I/O panel), I say "must" because it is normal for one of those features. Another thing is that what you call a network card is a modem, but that surprises me.

On the other hand, if it is worth as a reference, 2 7750 working in SETI@home, with a CPU usage of 25%, do not consume more than 125/130w.

The people from the integrated network card already told me, what I forgot to mention is that I connect via Wifi, the router is in a room next to mine, and I don't pay for the internet, it's what there is. That's why I have to buy a USB wifi adapter, it's the only solution.

The thing with the OC, was the silly thing that gave me the idea to try the tool that had the same driver, and to try it to the maximum, since I thought that being an OC through its own driver it was safe and didn't allow more to be raised than what is due, anyway as soon as I had that episode I put it back to default again (From the driver), I hope that it wasn't something to regret later.

Thanks for the help to both ^^.

Check out the new tacens mars gaming 700w. For 35€ it's pretty good. It delivers 550w at +12v. That's more than enough for mid-range cards like the r9 270X and even for an R9 280X.
