Urgent - wattage question

mrnothersan1 · 27 Dec 2014 at 16:35

I have:

i5 3570K
Corsair H60 Cooling
8GB RAM
Asus GTX 750ti (150W)
120gb ssd
500gb hdd

Will a Corsair 430W PSU be enough to run this or do I need to upgrade my PSU? If not, what wattage psu would you recommend?

Id say you would be better with a 550w.

If you aren't overclocking, you'll be there or there abouts. I have a similar set up but with 2 graphics cards and 2 HDDs and I draw about 520w from the wall on load.

However, to be safe, I'd agree with baz178 for 550w so you aren't high loading the PSU

Is the 150w on the Gfx card at maximum full load or at idle?

To be honest I prefer to have a bit of head room on my PSU I have the rig setup
in my sig and have a 750W PSU which if I want to upgrade gives me plenty of headroom for it.

Full load won't be over 300W, so you'll be fine.

I think you will be fine. CPU is about 70 watts (full load), GPU 150 W. RAM is about 15W (for 8gb) and the remaining Motherboard + SSD + HDD should be well covered by the remaining power.

For the Corsair H60 as well?

I am probably better off with a 550-600W PSU maybe?

Why spend £80 on that when this is £50:
YOUR BASKET
1 x SuperFlower Golden Green HX 550W "80 Plus Gold" Power Supply - Black £49.99
Total : £59.59 (includes shipping : £8.00).

I don't really want to buy something if I don't need it.

Is it possible to run everything on my Corsair 430W PSU or will it not work at all? Some are saying it will and others are saying it won't

Your current PSU will be fine as said by Jokester. I was just questioning why he chose a £80 PSU when you can get one for £50 which is just as good

Sorry its just the one I use on my gaming pc so listed it because I've had no trouble with it. But ye the one you have listed is just as good.

The closed loop water cooler? That would use like 12 watts at most I think. Even with the water cooler it appears to me that all your components should work fine under a 430 watt PSU.

You would get away with the Corsair, my old system with a Gigabyte 670 Wf and a overclocked 2700k with custom water pulled 330w from the mains at full load!

430W will be OK, as everyone has said you'll pull around 300 watts from the wall.

If you already have a CX430 then use it as it will work but if buying it now then get something better and 550w rated, the CX430 isn't made that well either.

pastymuncher · 28 Dec 2014 at 13:43

It will be fine but it's also not capable of 430w on the all important 12v rail. Depending on which version of the CX430 you have it can only do 336w or 384w on the 12v rail. When buying a psu ignore the total wattage and check out what the psu can actually deliver on the 12v rail, especially on budget psu's like yours.
