PSU HELP!!!! needed

brado380 · Mar 5, 2014

i am buying this computer http://www.pcspecialist.co.uk/quotes/intel-home-office-pc/Q0TrgyyYUq/ but i do not know what PSU i need, the website says 350W is enough but i am not sure please help

Danbuscus25 · Mar 5, 2014

umm, i would not reccommend 350watt. a good quality 480watt will be fine. you may be able to get away with that 350watt, but it will age faster.

babachicken · Mar 5, 2014

You do fine with a 350w psu. but it will leave you no room for upgrades later on in the future.

schau314 · Mar 5, 2014

I saw go for a moresuitable 500 or 550 watt. I am currently running the 550w xfx power supply. Any good 500w power supply with a 80+ bronze should be okay for your purposes.

swegname · Mar 5, 2014

I highly suggest you get a PSU with a more than 350W. It'll have a higher life time and I'm sure it'll have less heat.

Danbuscus25 :

how fast exactly?

babachicken · Mar 5, 2014

the 750 uses 50-60w, the 4440 uses 84w

this adds up to 148w at max load.

add other things and you will be only pushing 180-190w..

350w is MORE than enough

Danbuscus25 · Mar 5, 2014

like 1-2 years.

Okay im getting two answers here should i upgrade or not?

brado380 :

i am sure.

Dark Lord of Tech · Mar 5, 2014

Get a 450w and get 2 - 4gb ram modules so that it runs in dual channel mode.

The Nvidia recommendation for a PC with a single GTX 750 is a minimum of 400Watts for the entire system with a minimum of 20amps on a single 12V rail.
It is not the wattage that is important, but the amount of continuous current - amperage - that can be delivered on the 12V rail at 40-50 degrees C : a typical temperature inside a computer case.
The information I found indicates that that powersupply should have 25amps on the 12v rail: I could find NOTHING about how that it was determined so would guess it was at room temperature of ~25C. It is Not 80Plus rated.
VS is near or on the bottom of Corsairs power supply line up.It will probably power you computer just fine, but for how long is the question, and babchicken is right, no headroom for upgrades. In that regard Danbuscus is on the mark.
Don't know what your budget is but I would at least upgrade to a 430W CX or CXM unit, or if you can a TX (in the Corsair lineup). You might consider the CS 650 that is listed in this sites PSU selections if you are locked into using this etailer. Stay away from the RMseries,Corsair is still having issues with it.

UPDATE: Several answers while I typed and researched. SR-71 has suggested a really good PSU, but if you are locked into pcspecialist, get the CS 650.

Dark Lord of Tech · Mar 5, 2014

The problem with the RM series is the use of poor capacitors.

Danbuscus25 · Mar 5, 2014

yeah, that is a great psu, should last a very long time with little heat

Dark Lord of Tech · Mar 5, 2014

650 watts is overkill for your specs.

brado380 · Mar 5, 2014

babachicken · Mar 5, 2014

brado380 :
