ive recently bought a full new system
devil 480 rx gpu
AMD 8350
970 msi am3+
ace 700w atx power pack

basically ive been monitoring temps and cpu is fine ive ordered a aftemarket cooler as well for it

my psu only has a six pin pci connector but my gpu needs 8 i have read that this is fine


the gpu runs in the low 50c on idle

but as soon as i load any game or 3d benchmark

it instantly over heats and causes the computer the computer to crash do i need a new psu ? any ideas

all responses highly appreciated

ive also installed latest drivers for motherboard and gpu

It's not overheating.

The PSU isn't delivering enough power causing a crash.

Where in the world are you based, so we can send you to a shop for a new one.

I'll elaborate on why there isn't enough power.

Companies buy cheap nasty power supplies, Stick a sticker on then with claims of a set high power output. What you are actually buying is a 300W budget unit with a sticker that says 700W. In a lot of cases these PSU's run fine simply for the fact most PC users don't have a graphics card.

Graphics cards change how your power is delivered. On idle, in desktop they use very little power. As soon as you demand 3d then they start to draw on the PSU. You don't need 700W's to run most systems. 500W in a lot of cases is overkill. What you do need is to be able to trust what it says on the label is what it actually is.

In some cases PSU's have been known to catch fire, destroying a PC.

And the difference in price? Often it's £10-£15.

I can't find any reviews on that model of PSU. But 1: it's CHEAP so you get what you pay for. 2: it doesn't even have the proper connections. I would send it back and spend a bit more money and at least get one of decent quality that has the proper connectors.

Novatech matey. Spend £50 and delivery is free on 3-4 day postage. I recommend this company because the customer service is some of the best I've ever dealt with. You can badger them online over a chat system in office hours. Returns with them are also good and easy.

Personally I'd have the Bronze unit because it means the design has gone through more testing to get that certificate. EVGA are well respected it's not the highest rated PSU, but well priced, and safe. And your PC will be fine with either model.

If you feel you want 600W's and a bronze rating then:

the gpu runs in the low 50c on idle
As much as people pointing to PSU as the issue, i am not convinced of that. Running 50c at idle is concerning. Granted i have an nvidia card but my card even with fan in 0 mode (which is fans are stopped which is thing evga has done with their's on ACX cards, doesn't even pass 40c idle less its warm in the room to start with. Might have to check to see if fans are working right on the card, make sure no dust clogging(shouldn't be since new system) and even take the cooler off and Apply some new thermal paste since something might got messed up at factory.

Without knowing the case, airflow, and ambient temps that's a big conclusion to make. 50 celcius on idle is high, but not dangerously so, and no where near crashing temps that will be up in the high 90's.

That PSU with the 125W draw on the CPU will be kicking out a fair bit of heat as well.

The 480 is also a high idle temp card, In review conditions it was sat at 37-38c and I assume that was in an AC room. The UK doesn't use AC domestically.

50°C is normal on that GPU afaik, because the fans are off under low usage, every vendor handles this with different settings. But whether the fans are working or not isn't important, that PSU is cheap garbage and it should be replaced asap.

my psu only has a six pin pci connector but my gpu needs 8 i have read that this is fine
Does this mean you connected a 6 pin to the 8 pin socket of the GPU and expected it to work? :D Very obvious now that the PSU is the problem, nothing else.
but as soon as i load any game or 3d benchmark

it instantly over heats and causes the computer the computer to crash do i need a new psu ? any ideas
You're sure the GPU is overheating, or is this just a guess? Seems the latter to me, because I think the GPU needs more power, which it doesn't have with a 6 pin connector to 8 pin socket, and then shuts off.

We really need more info on this; 50C idle seems high but can you watch the temps before it crashes under load?

I agree a good power supply is very important but I would think even a low quality 700w should be enough to power that system at stock speeds.

Download HWInfo and look at voltages and temps!

As mentioned above already, replace the PSU, and then check temps using HWInfo.
You haven't mentioned what Case you have, or the number and type of fans mounted in the case.

He didn't make a conclusion, he made an observation and I agree with that.

I think that is jumping to conclusions at this point. While I have never heard of that PSU, according the Ace 700 Watt PSU specs it has 34A (408W) on 12V rail alone and that "should" be plenty ASSUMING the supply is working properly. I always want to verify good power so I would swap in a spare, known good PSU just to rule your PSU out. I would not automatically spend money on a new PSU in a problem computer just because I am not familiar with the brand, or because it is not 80 PLUS certified.

the gpu runs in the low 50c on idle

but as soon as i load any game or 3d benchmark

it instantly over heats and causes the computer the computer to crash do i need a new psu ? any ideas
50°C is just fine. You say it instantly overheats, but did not say what that temp is. So how hot is it getting? Note that GPUs can and do get considerably warmer than CPUs. 70°C for most GPUs is barely warm.

Open up the side panel and make sure the interior is clean of heat trapping dust and all fans spin freely. If clean, blast a desk fan in there and see what happens.

Just "loading" a game would not cause overheating. But it sure could hit on a bad memory location resulting in a system crash. Have you tested your RAM?

I don't think it is.

There are no decent reviews of the PSU, consumer feedback of it is dire.

There are less reviews for the 700W but if you look at the 750W by the same company it has 150+ reviews on amazon.

https://www.amazon.co.uk/dp/B006FUTT38/?tag=tec053-21

Those 750W reviews are shocking reads. The going off that information the company is about as bent as a spring.

Bad reviews don't mean that every sample has failed. Happy customers don't typically write reviews.

There are generic, no-name power supplies that keep chugging along after 10 years. Would I put one in my builds? NO! But that does not mean someone else might put one in theirs still have years of fault free service.

To be sure, I don't think that is a quality supply. But there are dozens of causes for a system to lock up that don't involve a bad supply. You have jumped to the conclusion this supply IS the problem. If he had said he had a decent Seasonic, you likely would not have immediately declared the supply was bad based solely on his description of the problem.

He has a 700W supply that is rated at 34A on the 12V rail. That is more than enough for his system. Yet you immediately said he does not have enough power. That is NOT true - unless that supply has failed! And now you are trying to justify your claims by saying because the 750W supply has bad reviews, the 700W must be bad. That is not valid reasoning. Some of Corsair PSUs are top notch. But others I would not own.

Yes, he needs to try another supply. But automatically replace his? Not yet!
