Vega 64 Issues

[XiiXii808]

So i'm having heat issues with my Vega 64 and power problems i had single 2x6 with a second 2x6 on the cable (Daisy chained i think its called) running from my new Cooler Master V650 Power supply to my graphics card should i use two seperate cables with 2x6 connectors going from the psu to gpu? I had GTA 5, The division 1 even minecraft running in 4k on the card and roughly 45 mins later my pc would shut down power led would still be illuminated by the system would be off completely. I'm not sure if using two seperate 2x6 cables would help with the shutting down issues or not? any suggestions? I use a gigabyte Windforce Vega 64 paired with a 2700X stock

VEGA 64 takes two 8 Pin PCIe connections.

 

Yes you need to use two separate cables, make sure to use all of the pins, not 6 each, has to be 8 each.

it's ok to use daisy chained cables, they are meant to do this. This is not the R9 295X2, it doesnt exceed power draw specs on its connectors.

The system is shutting down...

 

He needs to use 2 separate cables.

if it's a power issue it would have shut down right when the card and CPU hit max load and power draw, not 45mins.

 

@XiiXii808 what about the temperatures? Also motherboard model

No, not really, could be spiking, and straining the PSU causing it to overheat, that doesn't happen right away.

 

Could end up damaging the PSU over time.

bullshit, that's a decent 650w PSU, you need liquid nitrogen overclocking on the GPU to even risk hitting the PSU's output rating, and even then it still wont overheat because PSUs are designed to hold 100% load sustained. So is the voltage spikes, also designed to handle that.

My cpu temps dont go above 75 i use the wraith prism that came with the 2700X my Gpu got hot enough to burn my finger to the touch lmao my ventilation is just fine too i'll probably try running it off of two serperate cables to see if that fixes everything gpu is stock too not oc'ing it

Where do you people get these fairytales from?

 

He needs to spread out the load to two PCIe connections on the PSU.

Yeah do that, it will work.

You're still using that Gigabyte A320-S2H? Then you're overheating the VRMs powering the CPU, and it's shutting down to prevent a fire. In fact 45mins is quite a long time for something this terrible.

The V650 only has a single 12V rail, using more cables doesnt affect the PSU at all, all power to the GPU comes from the same rail.

 

Dont need to worry about the cables either, they are designed to send at least 25A through the 4 pairs of wires. The V650 uses 18AWG cables for the PCIe 8pin so the cable can actually handle 30A max without melting.

 

If you still don't agree, give some reasoning.

While that is true, you can overload the Pins on the PSU Side, wich will melt the PCIe Connector on the PSU Side.

While in theory It should work, in reality it is a high risk that also depends on the Temperature in that area.

with high power cards like VEGA64 there is a risk of damaging the PSU with one Cable!

In that case, I'd just ask Cooler Master Support if that is something they know about and what you can do about it.

 

Because that looks like OCP or maybe OPP trips.

they're meant to do it, but on a cheapo unit like the VS, it may not exactly be up to snuff

 

I believe @Stefan Payne has had experience with this

It's not a VS, it's a Cooler Master V Series, it's actually a very good unit.

Yeah, I try and get people to spread it out over two cables with the high powered cards. Seen a lot of issues over the years with people using one cable, normally just changing to two solves the problem. That's if the damage hasn't already been done before they do it.

 

I really don't understand how this theory came about, but it's caused people a lot of headaches over the years, damaged parts etc.

 

I beat my head against the wall every time I see it.

 

With the low powered cards it's not such a big deal and they can get away with it sometimes depending.
