GTX770 too much for a 550W PSU?

UnlimitedBanana · Jan 23, 2014

Hello, I recently received a GTX770 I had ordered, and I appear to be having a few issues with my system since. My screen just freezes, just like when I get a BSOD, but it doesn't show anything on screen, it just goes to black and the monitor turns off. It's done this quite a few times now (around 5-6 for the period I've had it). However, I have only noticed this happening when I am playing Euro Truck Simulator 2, so I have no Idea what the problem might be.
My system is as follows:
ASRock 970 DE3/U3S3 AM3+
AMD Phenom II 965BE @stock
2x4GB Corsair Vengeance DDR3 @1600Mhz
1TB Hitachi HDD
a DVD drive
MSI GTX770 TF4 edition.
Corsair VS550 550W PSU (Just over 2 months old, has not been under any severe load before I got the GTX770)

I have a few doubts that it might be the Hard Drive, seeing as it's nearing 3 years of age (with pretty constant use), but I am afraid it might be a PSU problem. Let me know what you guys think.

That power supply will run it fine dont worry

550W is enough for this build. Check the dump file, you will know the exact cause for BSOD. If possible post it over here

The PSU wouldent be the prbolem as you said your PSU wattage was 550w and that is exactly how much the gtx770 needs(source: http://www.game-debate.com/gpu/index.php?gid=881&gid2=517&compare=geforce-gtx-770-vs-geforce-gt-520 ignore the other card, scroll all the way down to GPU supporting hardware)

The Power supply will power your system however it's not optimal it's better to get a tx series or better if you game alot.

I upgraded from cx to axi series I noticed increased stability and performance.

ittimjones · Jan 23, 2014

The PSU might not be strong enough. Not enough power would cause those issues. I believe that card in particular draws more power than the reference card, and the reference card recommends a minimum of a 600W PSU. I had similar issues before due to my PSU, but it was cause it was a sucky brand that didn't perform.

Well, there's the problem. It hasn't created dump files for those crashes. I just used MSI Afterburner to lower my GPU's power limit to 90%. Hoping that works.

mouse24 · Jan 23, 2014

I'm a little confused. Have you tried other games and furmark? Does it do this in those applications aswell? (without your 90% power restriction)

A 550w should be more than enough for a 770.

Also record the time it has done this and check Event log.

ittimjones · Jan 23, 2014

That card definitely pulls more power than the reference card, which recommends a minimum of a 600W PSU. It's clocked almost 100Mhz higher, can have 2GB more than the reference card, and requires 2 8-pin power cables as opposed to the reference's 8-pin and 6-pin. I'd say that you would need 650W Corsair or Seasonic PSU minimum, but I would go with a 700W.

UnlimitedBanana · Jan 23, 2014

I just ran Furmark Burn In for 10 minutes, steady as can be. I'll try running it along with Prime95 for a few minutes.

mr91 · Jan 23, 2014

I suggest you get a RM 550 it's good certified and is a high modular psu.

45.8 amp on a single rail " more than enough for your card

This PSU has Japanese caps " quality and durability"

If you don't mind spending more money get a rm 650 or a high end Corsair or seasonic power supply.

UnlimitedBanana · Jan 23, 2014

I just ran both Furmark and Prime95, my computer sounds like a Boeing 747, but it's working with no problems...

UnlimitedBanana · Jan 23, 2014

mr91 :

Well, I just recently bought this PSU (thinking I was going to get a R9 280X, but then the prices skyrocketed). So I am kinda stuck with this one.

UnlimitedBanana · Jan 23, 2014

I just looked up some benchmarks, the GTX770 MSI TF4 along with an I7 3960X (Overclocked to 4.7Ghz) draws just over 400W at the wall. In theory my CPU should draw less than even an I7 3960X at stock speeds, therefore I should be running at around 400-450W of power for my whole system, right?

mouse24 · Jan 23, 2014

Yeah guys, he already has the PSU, its not a no name manufacturer, its a corsair VS line, its not bad. Assuming its not defective it will handle a 770 absolutely no problem.

Lets talk theoretical maximum power for a minute here (not including CPU overclocking because different models/architectures can get pretty crazy pretty fast)

GPU: 6 pin + 8 pin, thats 75w + 125w = 200w + 75w from PCI-E = 275w This is the absolute max you can ever see, the card can not physically accept more power without needing 2x 8 pins. Even before this temps are likely to be way overboard, thermal throttling is likely to set in and/or vrm failure is likely to occur.

Add in the CPU, 125w would be 400w, add in a few other components such as a hdd and optical drive + 10w for ram and chipset usage = 430w

Now while this might seem like alot out of the 500w he has to work with on his 12v rail its actually not that bad once we stop talking theoreticals.

For instance

Guru3d has it pegged at 200w, 303w for the entire system with an i7 3960x @ 4.6ghz: http://www.guru3d.com/articles_pages/msi_geforce_gtx_770_gaming_review,5.html

Toms has it at 200w gaming, 225w while bitcoin mining and up to 250w peak numbers: http://www.tomshardware.com/reviews/geforce-gtx-770-gk104-review,3519-25.html

Anandtech has it at 383w full system load while using an 3960x at 4.3ghz during furmark, bit less during BF3: http://www.anandtech.com/show/6994/nvidia-geforce-gtx-770-review/16

The Power supply has 42 amps on the single rail which will give you a total of 504 watts in theory is enough for a gtx 780.

I'm guessing your system will use around 400 watts give or take however you would be around 80% load on a low end power supply and that would reduce efficiency, increase heat and torture the components on the power supply.

This is most likely the reason why you're having the crashes and stability issues when gaming. You might even have issue's when you're not gaming.

This power supply can easily handle your system if you don't overclock it however it will not last as long and your system might be unstable sometimes.

UnlimitedBanana · Jan 23, 2014

mr91 :

I have done no overclocking, and it is only unstable in ETS2. When running Furmark and Prime95 it has no problems. (I am pretty damn sure those 2 put a LOT more load on my system, the CPU at least)

UnlimitedBanana · Jan 23, 2014

On second thought, when playing ETS2 I also have a steering wheel plugged into the system, maybe that sends it over the point of stability?

mr91 · Jan 23, 2014

I don't think so however it's possible - what other games do you play that are demanding?

You might have a usb issue.

mr91 · Jan 23, 2014

I also had problems when I was powering my previous gpu the gtx 780 with a cx 600 that has only 40a on the rail for a total of 480 watts.

The cx 600 is also bronze certified - The cx & vs series are not designed to power a high end gpu's even if you got a cx 750 you might have issue's

ares0027 · Jan 23, 2014

i am also having the same problem with fx-8350 and corsair vs650 (650 watt) and it happens almost in every game

mouse24 · Jan 23, 2014

mr91 :

The only problem with the CX series is that they are over rated by about 50-100w depending on model. They are not bad PSUs by any stretch.

@OP perhaps its just a problem with this one game?

mr91 · Jan 23, 2014

The Cx is good value in the budget segment however Ares0027, The OP and I had issues with the entry level Corsair power supply's when the psu was connected to high end hardware.

The Cx and VS are good value and in my opinion & one of the best psu's you can buy for around $50 dollars...

In my opinion these gpu's are good for integrated graphics and entry level gaming gpu's like the gtx 650.

My first cx series psu had a non functioning fan and I had to return it however at 50 dollars I can't complain.

how is the Antech mouse 24?

ares0027 · Jan 23, 2014

mr91 :

so you suggest that my psu is not providing enough power? (both power leds are green btw)

mouse24 · Jan 23, 2014

ares0027 :

The easiest way to test it to either pop the gpu into a friends pc with that has a better psu (or if he lets you borrow his psu)

Or to grab one from a retail shop like bestbuy/walmart/frys/etc then if you find out its actually the problem you can keep it. If its not the problem return it and pay the restocking fee (its only like 10-20% I think)

Oh and the antec I have is fine, most of their line up is quite decent. Would have liked modular cables and it not being... Well... green but I'll take what I can get for only paying 50 bucks for it

Performance wise its quite good, I've been using it for about 3 years now with a variety of equipment, handled them all very well.
