my Evga P2 1200W died, suggest me replacement PSU

probably 1200W was overkill for me, as I have 4 core 5775C CPU, and only one GPU without plans to run SLI.

but I did get 1200W before two years, one of reasons is why I wished to have futureproof PSU if I upgrade someday to more cores (overclocked, it can consume some W), and because this model had "Eco" mode, that means if power usage is below 50% it run without fan.

now, I can't find this same model. there is Gold, Platinum, Titanium models in Evga...

and, how much W is really needed for me? remember that you always had to have some reserve, never use full capacity.

for example, if one day I upgrade to 8 core overclocked, and have GPU like Titan Xp overclocked (I will always stay on one GPU).

can you suggest which model is OK to get now, depending on power, noise levels, quality, etc.

tnx

Why don't you RMA it? They have a 10 year warranty.

You dont need more then a 550 watt PSU to run a system with a single video card so RMA the 1200 watt sell it and get a 550-650 watt instead.

ok but doesn't overclocked Titan Xp consume up to 300W? as I said if in future I go for more cores, and overclock it, how much power that CPU can draw?

keep in mind that there are other parts which consume power, although CPU and GPU consume most.

and you should never consume all power of PSU, there should be some space left unusud.

sure 550 or 600W are enough?

also, which is differences between G2, G3, P2, T2 ?

Go for 750W, and G2,P2 etc.. is the efficiency of the PSU, from G(old) to T(itanium), the higher the efficiency, the lesser the power is wasted in heat.

I don't think you could pull 600W with that system if you tried. Titan could creep up to 300W but i don't think the 5775C couldn't draw 200W on conventional cooling. I personally cut off at 650W minimum just because I always change my plans in my builds and end up reusing them in all kinds of configurations, but if you've really gotta pinch pennies the 550W would cut it.

You're WAYYY over what you need bro

With one GPU the maximum you'd ever need with modern peripherals is about 450 with a nice rating

250 for the GPU

150 for other components

I'm not sure what the wattage is on those "threadrippers" with 32 threads, but I bet they don't draw 250 watts from the wall with mobos, drives, usb ports being used etc. And that's 4x the threads of a top of the line consumer CPU

Buy a smaller P2/G2, no more than 650 watt for a single GPU, maybe higher if you think you might try SLI

RMA the bigger one then sell it ASAP, you can probably sell it for more than you bought it for if they just send you a new unit. Cyrpto currency miners plus just general enthusiasts are pushing the prices on the larger* power supplies up

I dont know where that myth comes from but more cores does not mean the CPU will draw more power as the efficiency of CPU´s gets better and better so the power draw stays almost the same even with added cores

CPU power draws has stayed more or less the same for as long as i can remember with very few exceptions and unless there is some massive breakthrough in technology thats not going to change
Why does everyone think their PC hardware draws so much power when its been proven a million times that it draws far less?

Every major and minor youtube chanel has made at least one or more videos showing how little PC´s actually use
And its like 350 watts or less for a full liquid cooled system (with ONE GPU) with a bunch of fans and HDD´s and with overclocks on everyhing!

Edit: sometimes i feel like a freaking parrot because i am forced to say the same things over and over again

AMD's new chip is just 4 consumer chips spliced together

IDK what makes you think the "lawys of physics" need to be violated for it to have a much higher draw at the wall

Would it be a good choice in the context these CPUs are going to be used in? Probably not

A CPU drawing 300 watts doesn't break the laws of physics...It would just be poorly designed

Thats not what i meant what i meant by breaking the laws of physics is when idiots think new CPU´s will all of suden start to draw 500 watts for the CPU alone when overclocked just because a few cores was added

Not saying CPU´s cant draw more power just saying that they dont start doing it all of a sudden like magic pixie dust has been added or something just as random.
Edit: it was meant as a rant with a lot of sarcasm it was not meant to be taken seriously.

Well that's fair, I hadn't consided the context of the 1200 watt psu for the single gpu rig

I recommend corsair digital psu the AXi series, best in market currently quality wise imho

They are overpriced and there are options that are both better newer and cheaper like the new Seasonic Prime series just to name one
So no they are not the best.

1200W - he he, I guess i am not the only one tho likes to have some spare watts under the hood for absolutely no reason, other than psychological comfort of being future-proof.

EVGA are known for taking good care of their customers, no matter which retail chain you used. You will most likely be able to return the faulty P2 1200W unit and get it replaced or compensated.

Otherwise I 'vote' for a 650W Seasonic, because of CWT (the factory that makes them) is a OEM that makes PSUs for many other brands as well, but at least Seasonic is known for a good chunk of time and has a nice reputation and solid build quality. Also they tend to focus mainly on PSUs rather than having a gazillion other products.

One caveat - make sure the model is not from 2009 though, because I almost bought one old model, if it wasn't the help of this forum and particularly a user, who also replied here.

Good luck!

I heard 7900X can draw even more than 400W when overclocked.

Seasonic make their own units and CWT has never made anything for Seasonic
You are thinking of Corsair not Seasonic

No they cant and unless you can show me proof of that i refuse to believe that for a single second
Those 400 watts are for the whole system not the CPU alone as the motherboard and VRM would melt and blow up before the CPU would draw that much

Edit: here read this
https://www.techpowerup.com/234744/intel-x299-platform-called-a-vrm-disaster-by-overclocker-der8auer

VRM would blow up long before you got anywhere close to an overclock that would draw 400 watts.

corsair and seasonic are not far away from each other when it comes to quality; both are top-notch and both provide excellent warranty and after sale customer service, but corsair might have a bit more features (ex: corsair link, digital . . .) which might be considered useful by some and gimmicky by others so the buyer should be the judge depending on his needs.

as to pricing I didn't consider it to my criteria when I said corsair is best as I know pricing might be different as per region, for example in my region seasonic prices are higher than those of corsair with same wattage output so for us here choosing corsair over seasonic is no-brainer, don't know about the prices in the OP's region but then again he can see the prices for himself and be the judge
