can Corsair VS450 PSU handle the Gigabyte GTX 970 G1 Gaming GPU?

[mhs619]

i just ordered the Gigabyte GTX 970 G1 Gaming from Amazon. currently i have a Corsair VS450 PSU on my system with GTX 660. after i get the 970 on my hand, i'll sell the GTX 660 and the PSU so it'll take at least 10-15 days to sell those and to buy a new and better PSU.. So my question is, can i run the GTX 970 with my Corsair VS450 until i buy a better PSU?

My PC Spec:
Intel i5 4570 3.2ghz
Corsair Vengeance 1x 8GB
Gigabyte H81m S2PV MoBo
GTX 660 (selling it)
Corsair VS450 (selling it)
3 HDD'S
3x CM sickleflow case fans

P.S: excuse my bad english cause it's my third language

I would not use a VS 450 with a GTX 970 build.

The 970 can suck just under 300W alone on high resolutions, your CPU uses around 70W or so when its under load. That PSU is gold certified so should put out just about 440W or so realistically. With all the other components as well, I'd say that would be risking it to say the least. I'd wait until you get the new PSU first.

It could hold up your 970 but if something surges, its always better to have atleast 50w reserved. A 550W or a 600w shall put you at ease.

 

[guanyu210379]

Yes, 450W can hold on a GTX970 but it will run really near to the capacity limit.
PSU running near max is not a good idea.
But if you want only to keep the PSU for a few days, I would say...it is worth a shot somehow but the risk is quite high.

Thanks everyone for replying but i wanted a Real-Time answer (someone's experience) not a theoretical answer. cause i know GTX 970 G1 will need at least 30amps on the 12v rail of the PSU which Corsair VS450 has 34amps.. 12v rail output is the main thing isn't it?? and i also know that if i run the card with this PSU it will be a very close call of wattage that's why i'm asking.. though i could wait for 10-15 days, but just wanted to know surely so that i can at least test the card for 1 day at least.

It will work, I would still suggest upgrading your PSU when you have extra cash lying around.

seeing that your psu has a max of 32amp on a 12v rail, it will handle the gtx 970 fair enough. I may not have that on my experience but seeing specifics, only the you have to make sure is to have your hard drives connected to a different rail

yes you have 34amps on your 12v rail. but what else is on that rail. if you max the amps on a line or wattage totals you will fry your equipment.

Here is your real world answer from an industrial battery electrician with an IT background. electricity plays havoc on circuit boards when it fluctuates or spikes past its rating. if you run that card and the power spikes, it may fry the card completely or it may fry some components to a point where the card works but glitches forever more no matter the new psu. your previous answers were all correct. you want enough amps on the 12v rail to handle the card with nothing else on that rail if the max is almost met like in your case. you also want 50 to 100w more than all your components spiked at the same time will use.

For instance - a r9 295x2 has a tdp of 500w but in 4k and ultra settings will spike to 650 and as high as 710w. if all the components can spike around 350w, you would need at least a 1100w psu. assuming you have no plans to add more equipment.

hope this answers your question and prompts you to wait a few days for safety rather than testing the chance of having to buy another card.

 

[graand]

guy has a good psu, it wont fry other components but rather psu will automatically shut down. This is why I told him to make sure drives are hooked up on a diffrent rail

as far as i know, this PSU has a dedicated single 12V rail for the GPU. so how can i put HDD's on this rail?? excuse my ignorance..

Then you dont have to worry about that.

you're answer is factual and acceptable.. many IT Techs and my friends told me that it can easily run the GPU (some are using the PSU with this GPU) and as well as some said not to use it with this GPU (no real world frying result or stuffs). some even told me the exact words which you mentioned.. so the answer of my question is negative as well as positive.. I live in Bangladesh (Asia). power or electricity outage and low voltage is very common here.. so since i don't have plenty of money laying around 😛 i'll wait.. i can't afford any stunts right now..

One Quick question: Cooler Master V650 or Corsair CS650M??

Anyways.. thanks all for helping

 

[Suztera]

I would choose Cooler Master V650 over a CS650M.
Or get an EVGA GS650W or XFX 650W.

 

[ColdFusion 13]

i agree whole heartedly with the previous.... except i would personally step up a hair on the wattage. 650 these days is quite low. if it is a "throw away item" (meaning you dont plan to use it next major upgrade) then go ahead. but in this day and age, your psu is about the only thing besides a case that can be truly timeless in its future proofing.

 

[turbopixel]

Nvidia recommends at least 500 W. But this is to make sure, that even old and bad psu can bring the power. The high quality builds and with platinum rating, you can safely work with less W. I have 400 W and use it since some weeks, until I can buy a 500 W platinum rated high quality psu (fanless, no sound generating).

 

[guanyu210379]

Platinum or gold or silver or bronze..this does explain nothing about PSU quality nor max power rating.
It is only stating the power efficiency class.
Even from efficiency class, bad manufacturers tend to put higher efficiency class as the PSU really is.

For me, gold or platinum or whatsoever is only a marketing gimmick.
I pay more attention to test results on the internet, there are plenty.
The one I found very useful is the PSU Tier list on this website.

[turbopixel]

Gold or Platinum ratings aren't gimmics. They are standard certification about efficiency. A high efficient PSU need less power to generate a specific amount of watt, compared to one low efficient. And that does generate less heat, which means lower heat and noise generation also. So, this isn't a gimmic.
