My rig shuts off and restarts when gaming after buying an MSI R9 390x

SaltBucket · Aug 4, 2016

This has happened twice since I got the card today. This first time it showed up it said something about Asus Surge Protection and sent me to the bios. the second time it said nothing and restarted my pc normally. The first time I was playing GTA V and the second time I was playing BF4. I've mad no tweaks to the card whatsoever and this has never happened to me before. Any help you be appriciated.

System:

i5 4570
Hyper 212 Evo
R9 390x (MSI)
240gb SSD
600Gb HDD
Asus Z87-A motherboard
8Gb Corsair Vengeance Pro DDR3 RAM @2133Mhz
700w Coolmax PSU
Asus Xonar DG Sound Card

Found the problem.

Crappy PSU + high power draw graphics card = Asus Surge Protection getting triggered. The card draws a lot of power from the PSU, PSU output power becomes unstable, motherboard shuts down to protect components.

Replace it with a 650W EVGA G2/P2, Corsair 650W RMi/RMx, or 750W EVGA B2 and you're fine.

That's likely your issue right there. Coolmax have horrible, horrible PSUs. It's simply not capable of running a 390X reliably. 700W certainly should be enough, but the quality of the PSU matters significantly.

The 390 required a minimum 42Amps on the 12V rail - I believe the 390X's require a little more. Coolmax PSUs likely don't meet the requirements, and don't have sufficient protection.

Coolmax (and similar) and summarized well here:

Tier Five
Avoid IMMEDIATELY. These units are highly unsafe to use. No such protections added, very thin gauge wiring used, false advertising and too much to list. Reference to a higher tiered unit for a better, money saving and a much safer unit. For your safety's sake, please don't order or pick one up for use in your system. These units are a potential fire hazard and could even kill you, let alone your system.

Mr Kagouris :

So basically, I need to buy a new PSU that I didn't find at my dad's office?

burgessanthony · Aug 4, 2016

Yeah. Bravery points for trying that, but you need a quality 600-650w unit for a 390x.

Mr Kagouris · Aug 4, 2016

Yes you need a new PSU. Buy one of the ones I mentioned and you'll be fine (don't go with the 650W TS though as while it is a good PSU it may struggle in this case).

Barty1884 · Aug 4, 2016

Simply, yes. What's your budget & location? We can find something that'll work & be reliable.

Mr Kagouris :

Even something like the SeaSonic S12II 620W should suffice. https://pcpartpicker.com/product/nB3RsY/seasonic-power-supply-s12ii620bronze

That rig isn't going to be hitting over 450W at max draw (at stock speeds) - up to 275W for the 390X + 84W for the CPU + 100W for all else.

Considering current prices though, for $70 after rebate, you can have a SuperNOVA 850W B2 - can't go wrong, and you'll get endless upgrades out of it (and it'll only ever run <50% load)

Thank you all for the help. I'm a mere 14 y/o kid so I'm broke. So, what is the cheapest PSU that can run my PC without shutting it down. Also, should I stop using my PC until I get a new PSU or just stop gaming?

Barty1884 · Aug 4, 2016

You're looking around $70 for something reliable. On occasion you might find a decent sale. There's a bit more to it, but as a frame of reference: http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html Tier 1 or 2 (don't go with 3 or below). I'd say minimum 600W from Tier 1 or 2.

As for what to do in the meantime - personally I wouldn't use it. I know that's not the answer you want to hear, but you're putting your shiny new 390X (and the rest of your pretty respectable rig) at risk using the Coolmax unit. If you simply can't/won't not use in in the meantime, I implore you to downclock the GPU to reduce it's power requirements.

burgessanthony · Aug 4, 2016

That 70$ one quite honestly. You have a high draw system. I see 430w system load at peak gaming. 490w peak from the wall. Don't mess with poor psus at that kind if power draw.

Barty1884 :

Alright thank you for the help. Definitely not what I want to hear since I wont be getting a new PSU for a while but it's not worth risking. I will most likely go with that EVGA one since it is a trusted manufacturer. Thanks again for all the help. I probably would've destroyed my rig otherwise.

Barty1884 · Aug 4, 2016

If you're on a really, really tight budget - when it's all said & done, you can have this one for $45: https://pcpartpicker.com/product/fXCwrH/rosewill-power-supply-arc750

That being said though, it's $60 before the rebate, so you'd be out $60 to begin with - at that point, the SeaSonic S12II 620W I linked would be the better choice. Or, if going the rebate route, the 850W SuperNOVA B2.

SaltBucket :

As an FYI, don't focus/view it as a 'trusted manufacturer'. Barely any 'brands' you'd actually recognize 'manufacture' their own PSUs (the names beside each PSU model in the link I sent shows who actually make the PSUs). 'Brands' tend to outsource manufacturing of specific models (or even capacities within model lines) to various manufacturer's - resulting in varying quality.

SeaSonic are one of the only 'brands' you can blindly trust. They make their own. XFX are the same way, as all their PSUs are made by SeaSonic.

The common manufacturer's most people would recognize, Corsair, CoolerMaster, EVGA etc all have PSU's of varying quality, for various uses. One of the most common PSU "problems" we see on this site are Corsair's 'CX' line (admittedly, the latest revision is getting better) - people fall into the trap "oh, I've heard of Corsair, they must be good", when in fact, it's one of their poorer lines.

burgessanthony · Aug 4, 2016

^agree. Conversely, people now see 'corsair psu' and think 'there psus are rubbish' when in fact they make some good upper end units.

Ok will do. For now I'm using my PC with my old 270x and I'm not having any issues. The 390x is going back into the box until I get a new PSU.
