Sup guys. I want to power my PC with 2 power supplies. 1st one is 550w second is a cheap old 300w

Sup guys. I want to power my PC with 2 power supplies. 1st one is 550w second is a cheap old 300w.
My plan is to use the 550 for my gpu (r9 270x 2gb) and the 300 for everything else.
The issue is that I don't know what the fuck I am doing and I don't want to fuck up everything and/or die.

ok

halp pls

HI AUSTIN!

ok, bud.

yup, that is where i got the idea from...

What, why? 550w is enough for the whole system

gpu says that it needs 500w
cpu 100w
then there is the mb 2hhd 1ssd water cooling 2-possibly more fans

>gpu says that it needs 500w
what.

Your GPU won't ever use more than 170w

Your system board and CPU won't ever use more than 200w

The rest of your components are negligable, fans + drives probably only pull ~30w ( with fans at 100%, if you have 6 high performance fans)

Your system likely has an absolute maximum power load of ~400w, and only then when you are running synthetic benchmarks on both the GPU and CPU (with the 270x OC'd to like 1150/1600)

If you tell me your CPU and motherboard I can give you more accurate numbers

>water cooling
>2 PSUs

Why? It's like buying a $800 GPU and putting it in a $20 case. Wouldnt make a huge difference, but it's stupid considering the money you're spending.

Manufacturers tell people it needs a 500w PSU because if they said 'you only need 150 - 200w' people would be stupid enough to go and get a really shitty, cheap, quick to destroy the whole system PSU which cost £15/$20 and would hardly run the whole system at all.

By telling you to get a 500w PSU, they're trying to encourage retards away from shitty PSU's.

Your system won't use more than 300 watts you dumb fuck. I've ran an overclocked R9-290 on a 500W Bronze PSU.

They just mean the system as a whole will need a 500w PSU

Wow, can your gpu talk? :o

Get 1 PSU.
Not 2.

Try to get a PSU from tier 1.
Otherwise tier 2.
Try to avoid tier 3.
Avoid anything below 3.

550W good quality PSU is enough.

here it says 500
>reminder idk what I'm doing

cpu is amd I think phenom 6600k NOT SURE
quad core 3.9 with 4.2 turbo
on the papers it says 100w

Sure as fuck won't stay with the box cooler, the whole case starts vibrating when given a push

...Yes, I'm fully aware of this. That's exactly what I'm getting at.
Believe it or not, no GPU manufacturer wants you to go and buy a shitty PSU and have it blow up your whole system, because tech illiterate retards would INSTANTLY assume it HAS to be the graphics card since it told you to go for such and such a power supply, so they blame that since their old PC's always worked fine.
So yeah, they tell you something well over what the card would need and even then, they typically say a minimum of 500w anyway because that's when the decent PSU's start to be seen.

No manufacturer wants to be the one to recommend you cheap out on the single most important and liable part for any damage done to a system.

>System power supply requirement: 500W
>System power
It is talking about the whole system not the GPU alone. Gigabyte doesn't know what CPU or drives you have so they assume the worst case scenario with a FX-9590 CPU, 5+ HDDs and lots of case fans.

The 500 is a recommendation for the whole system.
Not for the GPU on its own.

The 270x has a 180W tdp, it won't pull more than that.

A 500 watt PSU is just so that even if it's a poor quality one you still have enough room for the GPU+CPU+HDDs and some other thingies.

Also look at the PSU tier list A good quality 500-600 watt PSU will be enough.

alright. my 550 is expensive, 80 bronze, pretty good quality (I think)

Well then, thanks guys, much appreciated!

>expensive
>80 bronze
Literally meaningless if you don't specify the brand and model.

Also you seem pretty retarded.

So from the replies to your thread, OP, it seems like as you're buying the 550W PSU anyway, just use that on it's own and stress test it for a couple hours when it's set up.

It was 60$ faggot
I have used it for half a year now. Didn't know what I was doing when building my rig. Always thought it was bottlenecking.

Sirtec EP-550S, 550W, ATX 2.3, PFC activ


this is it

OP somehow you managed to fuck up something as simple as a child's lego set with literally thousands of in depth tutorials available online.

How are you this fucking retarded?

Assuming it's the same Sirtec that was the OEM of OCZ's ModXStream Pro you should be good.
I happen to have a 600W OCZ of the same line powering a 4.3GHz X5660 and R9 285.

God you're an idiot OP.

>ITT OP is the biggest retard on earth

qq more twats

I laughed

>thinking a GPU needs 500w all to it's self
>especially a low-end one

I guess it's AMD so you're not totally off base. But still, you're pretty dumb.
