So I was playing on my PC when it suddenly shut down. I double checked if everything was fine, it worked until the boot screen then shut down again. I then noticed my case and fan were way hotter than before. I let it cool down, started it up again, everything was fine, got to windows login screen, I didnt want to risk more stuff happening, so I closed it. Today it wont start up at all though. Could it be that i got a new gpu that produces more heat and my fan isnt enough? Also I think its worth mentioning I have a prebuilt PC. Ive read that my PSU cant really tackle more than what it comes with. What should I do/try? Getting quite nervous. Thank you in advance

It's hard to know because there's not much of info provided, I don't know how many RAM sticks do you use or how much RAM do you have and in which frequency those RAM sticks are running, a generic as persay DDR3 RAM would consume like 2W to 4W, but it will increase it's power consumption depending on which Frequency the RAM is running at, for example a DDR3 RAM running at 1600mhz would consume less power than a RAM running at 2133mhz. Also it's uncertain that it will work since you have a "generic" PSU so we don't really know how much power it can provide even if it says it's a 700W one.. There are manual ways of testing it out but I think it's way complex at this points and you shouldnt bother... also you've got three options.

1 - If...

This is a very bad "generic" PSU, you should replace that with a real quality PSU. I'm sure you won't have problems with your computer turning off left and right... Try replacing with any 500 / 550 or 600W (Corsair, Seasonic, Coolermaster, EVGA) PSU with any +80 plus Bronze, it should be enough for your needs and provide better power supply. Tell me how it goes..

So it really is the PSU then? Thank god. Well i guess it did start so i shouldnt worry about something else failing. I had my eyes on a few good ones, I'll get one in a few days. I'll let you know but it should solve all the problems

Any PSU from one of these "brands" that I stated above pretty much comes with all necessary quality cables to provide power for your components, the only thing you should look at is the Watts rate and how many "Pins" does your GPU uses like if it's a 6 pin cable, 8 pin cable or both. As for the rest I don't think you should worry about "types of cables" as long as they are compatible with your motherboard, GPU and some other hardwares that you may have like (HD, SSD or such) if they are not very very old, I don't think you should have any trouble..

Also there are Non Modulars, Semi Modulars and Full Modulars PSUs the difference is that -

Non Modular - All cables comes within the PSU, there's no way to remove them, it's a little bit worse to do any cable management inside your case...

Semi Modulars - Only a few cables comes within the PSU like the ATX power connector of 24 pins and some 6 + 2 pin cables, the other cables that comes are totally detachable and optional, you can use only if needed.

Full Modulars - All cables are detachable and you can only plug those that you are going to use to provide power to your computer. Totally the best one out there for cable management lovers.

Hope that helps.

Oh, thanks a lot! Identifying the cables i need shouldnt be a problem since I can just look at the ones I currently have. Even if i dont somehow find a similar PSU i can just buy a molex and im set. Off to looking for some PSUs now

A little update, replugged the power cable a couple of times, pressed the start button and it works. I removed the gpu for safety, given the circumstances, do you still think the PSU is bad or could it be something else? Also, is it risky starting the pc and using it? If it shuts off again it might actually do something to other components next time?

It works because your computer is not processing any heavy task that demands a GPU power for it. As soon as you run any game or any task that heavy relies on GPU, it will start to consume more power hence your PC will shut it down again... I wouldn't risk it.. and yes it's a bad PSU. Your computer won't explode hehe but yes it could damage any component specially your motherboard.. due constant heavy loads or lack of power.

Thanks for the info! But if i remove my ram and just leave the 1 stick it came with, and start using my iGPU for surfing the web or watching videos, even playing some games; I should be fine until i get a new one, right?

1 - If you you can't replace the PSU for any reason.. try borrowing from someone you know that has a quality PSU from any of these brands with decent Watt rate, and test it... if your computer doesn't shut it down then I would say you found out the answer for your problems.

2 - You could do that as you state, but I wouldn't recommend it since it's a little bit risky and uncertain due lack of information regarding your PSU resistance, but anyways trust me it is generic PSU and it's dangerous for gaming.

3 - Buy a better PSU simply put. I'm pretty sure it will work in this case since you've said yourself taht it worked without the GPU, so that's it, your PSU is not able to hold the GPU power.

Hope that helps.

Hehe, I'll just get myself a couple of books to read until i get one in a few days. The minimum for my gpu is 500W(recommended) so any 500W+ decent quality PSU should do the trick. Im pretty certain at this point it couldnt have been anything else, because it actually runs, you've been of great help! Thanks!

Alright, after looking through em, I'd say either a corsair new vs series vs650, or a thermaltake (never heard of the brand before) TR2 S, 80+ 600W, it has good reviews and is apparently recommened for gaming. What do you say? I mean, I would get one of the ones you said, but I'm kinda on a low budget right now.

Yes, a Corsair would just suit you better, I haven't seem good reviews about Thermaltake PSUs, mostly say it's an okay PSU and sufficient at best... but if you could spend a little more you should get something better.

As for now, Corsair will be the best choice for your budget. But for a little bit more you could also go with EVGA PSU

and a really good one.

If you can spend a little more the 650 from the link I've suggested will be great in case you want to upgrade your machine in future so you won't have problems upgrading other components, etc... but if you really can't spend much right now a 500W will just sufice from any of these quality brands (EVGA, Corsair, and so on as stated above).

And yes your current one is just bad and doesn't seem to be providing enough energy even if it's a 500W I wouldn't trust.

Alright it arrived, i installed it, could say the pc even starts up a lot faster, compared to my other one who i could literally hear from upstairs, the new one doesnt make any noise, so far its perfect. If something goes wrong, WHAT THE FUCK JESUS? But im pretty sure it wont

Did you bought the corsair one? If so yeah don't expect loud noises or anything wrong with it as long as your PSU didn't come faulty from the seller... but I'm pretty sure you'll be fine, do some testing now with your GPU in games and see if it will shut it down now.. I'm pretty sure it won't.
