What PSU should I buy ?

Vlad F · Sep 30, 2014

Hello geeks,

I bought a new PC (by components) but dont know wht kind of PSU I should buy..

My new rig is :

GIGABYTE B85M-HD3 LGA 1150 MICRO ATX
INTEL CORE i5 - 4590, 3.3 GHz, 6MB Cache
2x KINGMAX DDR3, 1333Mhz, 4GB, 1.5 V

A friend suggested a 650W 80+ corsair but i want to see your suggestions.

budget is £100

thank you!

Which GPU you are using?

Shane501 · Sep 30, 2014

It all depends on the graphics card(s) but that system only requires a 200-300w PSU.

Are you using the onboard graphics or do you have a PCIe graphics card installed? If so, what is the model number?

If you're using the onboard graphics, this would be fine and it's a Tier 2A unit so it's a very high quality unit.

Thank you for the replys guys !

I dont have any GPU's yet, i will use the one on my CPU, which I understand that has one incorporated ( Intel® HD Graphics )

Then the one outlined would work just fine for you and is a high quality PSU. You don't want to ever use a low quality PSU and you also don't need a 650W PSU for your system unless you plan to upgrade fairly soon to a discrete graphics card.

EasyLover · Oct 4, 2014

Vlad F :

That is true. Your i5 has built-in Intel HD Graphics.

Vlad F · Oct 5, 2014

Ok thats interesting !

A friend has this one and he can give it to me if it works : http://ecx.images-amazon.com/images/I/51eupDC4TeL.jpg

Do you think its good ?

Also, I would like to upgrade and buy a GPU, but later...so my question is > can I install the 650w PSU without damaging the components I have ?

Here's what happens to power supplies like that one.

Darkbreeze · Oct 5, 2014

Yeah, that's a Sumvision Power X3. All of Sumvisions PSUs are on the Tier 5 "Replace immediately" list. For your sake, don't use that PSU.

Vlad F :

I can't understand people willing to spend large portion of their bucks on expensive components taking that these are necessary for performance but when it comes to PSUs, they give a tiny portion of their money to this component. Wrong very wrong. A good quality PSU is not an expenditure but an investment to safeguard the other components.

Don't install this PSU. Better buy Tier 1 or 2(a)(b) category PSU. Even you can buy Tier 3 category PSU if you are not overclocking.

Vlad F · Oct 6, 2014

Ok guys thank you so much for the advices ! at least i know something about PSUs now hehe

I will go with this : http://www.amazon.co.uk/Corsair-CP-9020078-UK-Builder-Series-Semi-Modular/dp/B00GMIPO46/ref=sr_1_4?ie=UTF8&qid=1412586894&sr=8-4&keywords=PSU+650w+80%2B

Seems like Corsair is a pretty solid one

EasyLover · Oct 6, 2014

I would rather consider these:

Vlad F :

Actually, just about anything from Seasonic, XFX, EVGA or BeQuiet is a safer bet, but if it's at least Tier 2B on the list, the brand probably isn't as important since it's been tried and tested true.

Vlad F :

The Corsair CX series uses poor capacitors... I would suggest a power supply manufactured by XFX or Seasonic.

Darkbreeze · Oct 6, 2014

sora :

Sora, I don't think anybody recommended any models from the CX series. But your notations are correct in the event that somebody was looking at using one of the CX units. They are Tier 3 units and we've seen a substantial number of failures with them throughout various threads.
