Will my PSU handle the GTX 770?

[EnthusiastGamer]

Hello guys,i'm wondering if my PSU can handle a GTX 770,this is what i currently have in my system:

-CPU - i5 4690K @ 4.2 Ghz
-1x WD HDD 500GB
-4GB of DDR3 Ram
-No optical drive
-Asus GTX 560 Ti DirectCu II Top @ 1000/4500
- 4x Case fans for cooling
-Asrock H87 Performance Mobo

I've been running the GTX 560 Ti Overclocked with no problems on this PSU but i'm not sure about the 770 though.I'd really appreciate your answer.Thanks ! (btw this PSU is cancelled atm,i bought it 4 yrs ago with 60-70$)

Here's a PIC with the PSU's Voltages/Rails:

you should be fine. High Power used to make PSUs for OCZ (or they 'were' OCZ) and OCZ PSUs were quite good

Thanks mate Cheers !

It's not 80PLUS certified, and it uses Sirtec as an OEM (Same as Rosewill FWIW). Dual rail clocking at 438W on the 12V is OK. Certainly I think it would run it. Would it be a wise decision considering the cost of your hardware? Most definitely not.

You've got a Devil's Canyon i5 K and you're getting a 770. Don't cheap out now, get a decent 80PLUS certified PSU.

I agree w @RCoon , your current PSU will run the 770, but it would be a good idea to replace it with a more efficient and reliable PSU, like a Corsair, XFX, Seasonic, Antec, or another brand name known for quality PSUs.

Yea well,took me a while to save the money for that CPU/MOBO/RAM/Cooler as i've changed my platform but i'm almost broke atm so what i could do is to buy a new PSU and get the GPU later(later meaning 3-4 months+ or get the GPU now within 2 months max),but if the GPU will work on this PSU i won't change it untill i'll get some other hardware such as an SSD and some more RAM,then i'd go for a new PSU.
All i wanted to know is that the 770 will work on this PSU,and as you guys said that it will then i'm really happy about that

EDIT:Indeed you're totally right about that but i'll get a
Corsair NEW VS Series VS650 soon enough after the GPU then

 

[BarbaricSoul]

Yeah, just make sure when you install the 770, try to use power connector from each 12v rail, if your PSU has them marked some kind of way to show that

 

[RCoon]

try to use power connector from each 12v rail

This. Although it's quite easy, because the PSU only has 2 6pin connectors anyway!

 

[BarbaricSoul]

Hey, just realized that no one asked this, does your current PSU have both a 6 pin and 8 pin power connection for the video card?

This. Although it's quite easy, because the PSU only has 2 6pin connectors anyway!

then it will not work with the GTX 770, the 770 requires a 8 and 6 pin power connections

from TPUs review of the GTX 770-

 

[EnthusiastGamer]

Nope the PSU has 2x 6 Pin power connectors.I know that the GTX 770 needs 1x 6 pin and 1x 8 pin power connector.Can't i use 2x Molex to 8 pin for that?

yes you can, your good then

Oh boy... we're delving deeper into awkward territory here. Yes you could use adapters. Should you? ... mmmmm. I know it's been said there's no real issue with it. Just makes me feel uncomfortable personally.

 

[EnthusiastGamer]

Or i could use a 6 pin to 8 pin PCIE instead if the Molex connectors have different rails.
Yea well i gotta do it anyway since i don't wanna wait 4 more months to get the new GPU ^^

Judging by the fact the R9 295x2 completely craps all over PCI-E Power recommendations and still works, I'd say you're probably safe doing so.

Alright,thanks a lot once again

The only thing I would advise is get a new PSU as soon as you have the money for it. I wouldn't wait until you had money for SSD and RAM and then get a PSU.

Yup that's what i'll do and i think that i'll get a 970 instead of a 770 which consumes less power 230 vs 145W.

Well, if you're using the monitor in your specs 1440 x 900 at 75 Hz then a GTX 970 is overkill but it would leave you room for a monitor upgrade on down the road if you wanted too.

Yea well i have a 24 Inch LCD TV @ 1920x1080 i can use that one for benchmarks/gameplays and stuff like that till i'll be able to get one on my own.

 

[bubbleawsome]

The 970 actually seems to hit a TDP wall at 180-200w. It should still fit within that PSU though. As long as it isn't too old it's the same basic build as mine and mine can power an i7 and overclocked 280x.

 

[XSI]

if you can afford 970, go for it. better gpu, more fps, less power.

 

[peche]

this is the principal problem for many people starting a build, the most important part for a good build its always a certified PSU,

personally I don’t trust those molex converters for Video cards, I would upgrade my PSU First, a way better to all PC components, considering you have a nice one,
Also the fact that a 970 consumes less power than a 770 would be another reason for getting a decent PSU, as your hardare is getting more and better you should try to take care for it for example…

There are many accessible ones for your build, take a watch:

· $42.99 Corsair CX: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026

· $49.99 Thermaltake Smart 550W: http://www.newegg.com/Product/Product.aspx?Item=N82E16817153172

· $49.99 EVGA 500W: http://www.newegg.com/Product/Product.aspx?Item=N82E16817438012

· $53.99 Thermaltake TR2 500W: http://www.newegg.com/Product/Product.aspx?Item=N82E16817153216

· $54.99 Corsair CX: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139027


I have been using thermaltake products for more than 8 years without any problem or issue, PSU's Coolers and cases, owned at least 5 TR Series, 3 TR2 Series, 1 TR2 RX and 1 SmartPower, they worked ultrafine for me since 1st day of use till the last day, and also none of them have died o stop working, I've changed them due computer upgrade or sold with computer parts,

currently saving money to get: Thermaltake Toughpower 750W GOLD Or Toughpower DPS 750W

 

[EnthusiastGamer]

I'll get the card first and then i'll buy a new PSU as soon as i can.

^ ive heard mixed opinions regarding the CX line of PSUs. most low/mid range builders i know avoid them
