Can my PSU handle a GTX770?

[jocau]

Hi all

I've just ordered the Gigabyte GV-N770OC-2GD. My current system consists of the following hardware:

- Intel Core i5 2500K (not overclocked)
- 6 GB DDR3 RAM
- GTX460 1 GB
- Nexus NX-5000 R3 530W
- 250 GB 7200 RPM SATA HDD
- NEC DVD Writer
- Two 120mm case fans

More info on the PSU:

Just wondering if the GTX770 will run stable when both my CPU and the new GTX770 are not overclocked.

might help if you post the PSU info

Can't you see the image? Didn't it show up?

I dont see an image. Maybe a link to your psu or at least the model number?

Strange... These are the specs:

its shows up now..

Acording to this you should be ok. I would plan on a new PSU in the nextyear as running them close to max seems to lead to early failure.
http://www.extreme.outervision.com/PSUEngine says you need a 430 watt PSU

 

[jocau]

The max load of a GTX770 is about 246W? And the max load of my non-overclocked CPU is about 109W (together 355W)? I was thinking that 492W on the +12V rail should be more than enough then?

 

[BillBright]

When I use the excellent eXtreme PSU calculator, I like to tweak the settings to accommodate for potential (even if rare) "peak demand" scenarios to ensure the PSU can handle the demands and continue to provide "stable" power.

So I set both CPU Utilization and System Load to 100%. Also, because all electronics degrade over time, I set Capacitor Aging to 10% minimum (see note 4).

When doing so, the calculator reports 461W minimum and recommends 511W. Note if buying a new PSU, I would set capacitor aging to 30% to ensure I had enough headroom for future upgrades and in that case, the recommended increases to 595W.

If me, I would buy a new PSU right away - and I would get a 600W minimum.

Also, if you note the Gigabyte page you linked to above, they too recommend a 600W supply.

You'll be fine. Might not be able to OC like mad, but otherwise I think you'll be okay.

How long have you had the NX-5000? The main capacitor is a Teapo rated for 85°C, it won't last forever. The maximum capacity now may be quite a bit lower than when you bought it

Good question. I think at least for a couple of years now. But I have to say that it's my "game only" PC which basically means that it doesn't get booted every month. Sometimes I play 8 hours a day, but there are also times when I don't game for 2-3 months in a row.

Crap, you guys got me scared, so I ordered a Seasonic Platinum Series 660W which has the following specs:

I guess this one will be more than sufficient. My GTX770 is going to arrive today. Would it be safe to start gaming with the GTX770 with my current PSU? The new PSU will probably arrive on Monday or on Tuesday.

^ Nice, did you get that idea from Lehtv's sig

You could have first tried the PSU out to see how well if would have done before buying another PSU.
Not a bad unit, made by ATNG and 80 Bronze. It has enough power for your GTX 770. The Seasonic you purchased is obviously much better..

my 2cents

 

[PowerYoga]

if you're buying a PSU there's actually one on sale today for a 750W corsair for $80 AR. Don't want to cross-post so just search slickdeals frontpage.

 

[Erenhardt]

If your wallet can handle gtx 770, then your PSU shouldn't be a problem

 

[Teizo]

Well, that Seasonic is great. I have the 760, but your old one would have been fine.

-Edit-

The 760 is $40 off right now with code EMCWXWW47 for $129 bucks, plus an extra $20 mail in rebate for a total after all deals of $109. That is a steal. And, if you ever want to go mad and go SLI it will run that just fine as well. I have never seen 500 watt pulled on my set up with my 760s overclocked pretty highly.

/Cancel that 660 watt order unless you got an even better deal

Nah, I have a Seasonic Platinum Series 760W in my server, so I know these PSU's. They are the best and as long as Seasonic is "king of the hill", I will not buy a PSU from another brand anymore.

Delta is currently king of the hill with their new HCP line The Seasonic KM3 is a close second.

"I'm not too surprised. There are very few companies on earth able to outdo Seasonic, and Delta is one of them.
this beast is pretty well unmatched for performance right now, coming in here and just obliterating the competition with unreal stability and ripple control. Only two current platforms I can think of can even come close to this - the Seasonic KM3 and Super Flower Leadex. But, neither one of them quite has either the rail stability or ripple suppression both to match this one"

Well, at first I didn't want to upgrade my PSU, but I don't want any damaged hardware because of an underspecced PSU. However I did notice that I often hated the cable mess of my Nexus PSU (it's not a modular PSU).

So again my question: can I use my GTX770 on my current PSU until Monday/Tuesday without damaging any of my hardware?

Thanks for the offer but I'm from Belgium so I mostly order my products on Belgian/Dutch webshops.

I don't think you will have any problem at all. I doubt your system under load will pull more than 350-425 watts since you are not overclocking.

The 660 was a good choice though because most PSU's sweets spots under load are around 50-80%.


/On a Linus Tech Tip video he had a Haswell mITX system with a Titan using a Seasonic 550 Gold PSU and it did fine, btw...You don't have a Haswell, but then again the 770 is not a Titan either lol

Completely understand - To answer your question - Yes, you will be fine :thumbsup:

Well, for me "king of the hill" stands for 2 things: Performance (50%) and Acoustics (50%). And it seems that Seasonic is rock-solid in both categories.

I thought someone buying 770 sleeps on money. If so, then frying whole PC make little difference. He just goes and gets a new one.

To me, anything that have more than 400W, or quality 400W is enough for single card setup (single GPU). But I'm not an expert when it comes to PSU

Yo, prices for the R9 280X in Europe are not what they are in the States it seems. In the States it's a no brainer which way to go, but over seas the prices are much closer.
