PSU might be defective

[ChiliPeppers]

Hello everybody.

I have a big big trouble. I bought a pc last month and i builded it myself. Specs:

i7 4770
asrock h87 pro4
gigabyte r9 280x
Samsung 840 EVO Series 2.5" 120GB
Barracuda 7200.14 1TB SATA3
G.Skill F3-12800CL9D-8GBXL Ripjaws X
AeroCool Templarius Imperator 650W 80Plus Bronze
Thermalright macho 140

It works perfectly fine but when it comes to gaming or benchmarking, in other words, stressing the GPU, it reboots. For example, I start Crysis 3. The menus and everything are ok, but when it loads and it starts the ingame gameplay it instantly shuts down. It lasts from 0 to 30 secs (thats why i think that is not a heat issue).
Same with Furmark and other benchmarks. I ve tried less heavy games like tf2 but it stills shutting down. The shutdown is spontaneous and after 3 secs it restarts again without showing any message. The event log register it as a kernel power failure.
For normal usage like posting here or listening to music it works fine.

I e-mailed the internet store where i bought the components, describing my issue and they told me to send them the PSU and the GPU. They said that the GPU was defective so they send me back my psu along with a new GPU (same model).

I tried everything. Drivers, BIOS, memtest... Im 100% sure that is not a heat issue, the temperatures are very reasonable. In my opinion everything points to the PSU.

As far as I know, Aerocool does not enjoy a particularly good reputation. Looking here:
http://www.plugloadsolutions.com/80PlusPowerSuppliesDetail.aspx?id=3&type=2 I see no Aerocool 80+ Bronze units that are 650W, so the label may be an outright lie. If that is the case, it's probably [near] junk, as a 650W PSU should have no trouble with your rig. A good 550W Seasonic-built unit would be sufficient.

Yep I totally agree with you, I discovered a tier list concerning different models and brands of PSU and Aerocool is almost at the bottom. Its placed in the 4th tier (out of five)

Quote "Tier 4 units may have some problems, such as being unable to deliver rated power at higher temperatures, or being slightly out of ATX spec on power output quality. Not recommended to buy except in situations where you will not be stressing it, or expecting it to last for more than a few years. If you have one, you can probably keep using it unless you're experiencing problems. "

That is what made my mind up about this PSU being a total piece of... useless metal (?)

More info that I forgot:

When I unplug the GPU out of the PC build, I use the intel graphics and it works fine. But this leads to no conclusion because the main Watt sucker is out of the pc

Yes, and the machine's gaming capabilities go down the crapper. Well, it sounds like you know what must be done.

Should I contact directly with aerocool or with the internet store where i bought the whole set?
Does warranty cover this?

 

[Onus]

I wouldn't waste time with Aerocool. You might contact the store. Describe the problem, point out that the PSU they included may not truly be certified so they may have been rooked into selling you a bad product. Give them a "clear out" to put the blame elsewhere, but you need a good PSU. Be prepared to pay the difference between the Aerocool and a decent PSU, but expect them to pay shipping.
If the PSU doesn't fix the problem, cross that bridge when you get to it.

Thank you very much Onus, you are helping me a lot.

I contacted the store a week ago because of this problem. They told me to send them both GPU and PSU.
They did the following tests: my PSU with my GPU failed, my GPU with another PSU failed too and finally my PSU with another GPU (same model but another card) this last test according to them was ok. They concluded that the issue was on the GPU so they sent me back my PSU with a new GPU (same model).

This morning I received both items and mounted both in my PC. It did not change anything, the exact same problem is triggered.

I sent an e-mail to the store this evening but they have not answered back yet.

I will send them the link that you posted before in another email
They paid the shipping last time so I suppose they will do this time. They are very formal and kind.
As long as they make me pay only the difference between the PSUs it will be ok.
I have a pc store near my apartment so maybe I can tell them to plug one of ther PSUs and see if it works but I don't want to spend more money on this.
Im a bit pissed off because it's been almost a month since I payed the PC and I have not enjoyed it.

Your environment could be sufficiently different from theirs for the same setup to work for them but fail for you, for example a 10V-15V difference in the mains power (if yours is lower) would put more stress on the PSU, and if it's borderline, cause it to fail.

 

[ChiliPeppers]

Do you think that this PSU will be good for my setup?

Corsair GS600 V2 600W Gaming Series

 

[Onus]

That one should be sufficient, yes.
