PC won't power up with graphics card plugged in

So, as the title says, I can't start up with my graphics card plugged in.
I started it like 1 hour ago, all went fine, I started CS:GO and after 2 minutes after idling in the menu, pc froze, some weird noise in my headphones and I restarted my pc.
It doesn't boot up.
I removed the graphics card power from my PSU, plugged it back in the onboard graphics card. Works fine.
Could my PSU have not enough power to start with my graphics card again ? or the graphics card broken just like that ?
i got a 470W PSU and my video card is a HD 7770.
First time posting here, tought you guys can give me some help.

video card is kill.

>AMD

Found the problem.

I fucking knew i should've went with gtx 650, tought this one's better, comparing stats.
So the video card just broke on me, right ?

470w psu

What brand?

Kelper is kill

Probably.

AMD GPU failure rate is extremely high, pic related.

psu is dying or was never strong enough to run the card in the first place

7770 uses 90 watts idle, ~200 peak, which you were probably hitting leaving it idle on the menu

your 470W is probably JUST powerful enough to run that card, a mid-range cpu, a bluray drive, 2 ram sticks, a 7200 rpm 3.5'' hdd, and the necessary peripherals, but you're seriously running with zero headroom on that build

Use default settings in the BIOS and try to replicate the issue with FurMark. Also check your temps and see if they're hitting too high

This is the PSU, 450W, my bad.

>First time posting here
Nice try Nvidia shill

I came all the way from /fit/ here.

30 euro psu.
You would be lucky if it was a true 300 watt if its that cheap.

450W is plenty with that GPU

never heard of Techsolo as a reputable PSU brand, might as well be a noname

what I would do next:
- check if GPU is dead: try GPU in another computer
- check if power plug or cable is dead: try one of those molex to 6pin GPU adapters
- check if that PCIe slot still works: try another GPU, or switch slots

Sounds like your power supply is marginal.

Even if it's a 300 watt PSU, shouldn't the system never start in the first place ? I ran it for like an hour without playing anything, and idle in csgo for 2 mins. I'm testing it tomorrow at a friend, I really hope it's the psu's fault, and not the video card's.

>your 470W is probably JUST powerful enough to run that card
Do people realize that PCs are much more power efficient than before?

I would definitely do what said, but figuring out if it's the PSU is the most important thing.

I'm already running a zotac gt430 synergy edition 2GB replacing that, on the exact slot, works fine.
And about the power supply, I had to make the system on a budget, the video card is second hand, I even replaced it's thermal paste, tought that'd be the problem

You should really check if the fan is plugged in on the GPU.
Did you use conductive Thermal paste, did you use a lot of thermal paste on the GPU?

Channel Well manufactures Techsolo PSUs.

The fan is working, connected into the GPU and all that stuff.
I've probably exagerated by a bit with the thermal paste, but I think it's probably enough, should I be greedy with it ?
After I started it with the thermal paste renewed, same results, idling and it restarted every now and then.

More people have older amd GPUs than older nivida GPUs so there is that

>I've probably exagerated by a bit with the thermal paste,
This is actually good, the die is exposed, so you want as much thermal coverage as possible on the fan heatsink.

Ty testing that GPU in another machine, if you did buy it used and it pooped out, well that sucks.

The exact same thing happened to me. The GPU was dead.

Thank you all for helping guys, let's hope it's the PSU or that I can repair the video card at a service.

>/fit/
fuck yeah. Put down the geams and get them gains

You can play CSGO with integrated graphics.

I wouldnt be surprised if tat PSU caused a power surge and killed the card.

badly

Same thing happened to me last summer. Literally the same gpu from sapphire. It's dead, user. Replaced it w a 750 ti

Quick question since this is a graphics card thread:
I have an extremely limited budget for a graphics card - I found a friend who has a geforce 770 that he's willing to sell in a month or so but I'm getting anxious and may cave in on a 750 ti. Should I wait? How large is the gap between the two?

The performance gap is rather large. If your friend is selling the 770 for the same price you'd be buying a new 750 ti for, then jump on the 770. Otherwise get the 750 ti. Or save and buy the 3GB gtx 1060.

>Rx 460 is also an option.

This. That PSU brand is probably some cheap quality Chinese brand and out of the 470w, it's probably only giving you 200w realistically. Or could have just surged and fried your card.
