Need help choosing a PSU and Case

bwrwgamer · Aug 15, 2014

I am looking to build my own pc at a price point of around 400 pounds (420 max)

I would like your opinions on which case to buy and I need help choosing a PSU (I am open to suggestions on other components)

This is my build so far.

I have chosen the GPU but can not find it on part picker so here it is http://goo.gl/5OYM5A

Thanks

You have to tell us the purpose of you build bro.

shogunofharlom · Aug 15, 2014

Is it for gaming, htpc, general office, editing, watching movies. Do you want something you can put on the floor? Do you want something you can take to a lan party? Do you want to upgrade in the future?

Darkbreeze · Aug 15, 2014

I could suggest many if you were in the states, but most of those models don't seem to be available in the UK. This is a good one.

Ha. Shogunofharlem. I haven't seen that movie in years. Loved that movie. Sorry about the off topic I just had to interject that.

shogunofharlom :

The build will be for general computing such as internet bowsing, maybe some htpc or streaming server. I will be using it to play small games like minecraft and I might be using it for programming in the future.

shogunofharlom :

Yes I would like to upgrade in the future.

That PSU should be fine, even if you upgrade the CPU or GPU in the future unless you have plans to go with an SLI or Crossfire setup using high end cards.

bwrwgamer · Aug 15, 2014

Darkbreeze :

Does that PSU not seem a little overkill for such a computer. Do you know of any 500-600W PSU's that are really good.
Also do you recommend a good atx case for around 40-50 pounds?

A few minor changes, for the better.

Thanks to all of you for your help. The build from Karadjgne appears to be very solid so I will choose that one.

Darkbreeze · Aug 15, 2014

That GPU calls for at least a 300w psu by itself, minimum, not counting the processor, board, fans, USB devices and any CPU cooler you may run. PCPartpicker calls for 152w, plus a 300w card, additional wattage for overclocking which could be as much as 30 more watts depending on how much you overclock and how. Consider you wanted some headroom for upgrading in the future, and if you do upgrade pretty much any cpu you buy will use WAY more watts than that G3258 does, and a bit extra for peaks it's a more than you need, but not that much more.

And if you ever do an SLI or Crossfire setup, it might not even be enough depending on the card. You could probably get by with one like this if you don't plan to upgrade later, or maybe even a small upgrade.

bwrwgamer · Aug 16, 2014

The GPU does not need 300w to run, that value is stated as the minimum recommended for the entire system. The GPU itself only draws around 70w at peak load as shown here.

http://www.tomshardware.com/reviews/geforce-gtx-750-ti-review,3750-21.html

However I will take your advice for upgrading and bump it up to the XFX Pro 550w

Darkbreeze · Aug 16, 2014

Every calculator I ran for verification added a SEPARATE wattage of 300w for that card in addition to the wattage called for on the rest of the system components and the overclock called for 100w on the cpu alone.

Karadjgne · Aug 16, 2014

A 750ti with no additional power connector uses the PCIe slot which has a maximum of 75w available. The cards themselves only pull 63-65w. PCIe is 75w, 6-pin is 75w, 6+2(8)-pin is 150w. The cpu is 53w, +@100w oc, +@50w for drives/fans. Total is @263w. The varience comed in with differing amounts of fans at different draws, but basically you are looking at @ a 300w maxed out system.

Darkbreeze · Aug 16, 2014

Guess I don't use calculators anymore. Except the kind on my desktop. And what do you calculate if he adds another card of the same type later for an SLI setup?

Karadjgne · Aug 17, 2014

Easy, nothing. 750's don't sli

Karadjgne · Aug 17, 2014

Unless you know exactly what a card will pull, my best answer is the power connectors will give a safe close bet. Take my 660ti for instance. It has 2x 6-pin so thats 75x2 + 75pcie. So 1 card can theoretically pull 225w. So 2 cards is 450w + 50 for drives/fans + 84cpu + 150 for OC. So I'd be looking for a psu in the 700-750 range for sli. As it is i have just the 1 card so thats @500w. I'm running a Seasonic 520mII, so I'm more than good. Those are maximum numbers though, my 660ti wont ever pull the full 225 unless i OC the hell out of it, and probably not even then, nor will i use 150w on OC, so i have plenty of headroom when it comes to adding stuff like extra case fans, liquid cooling, leds etc. It also means my psu will never reach 100% load output, realistically thats a good thing, it is more efficient, runs cooler and much quieter at 70%-80%.

So, in answer, if you take the original build @300w, you'd just add 75w more for a pcie powered card, total being 375w, so even a builder special cx430 would be enough, for this particular build. Most builds dont have a power draw as low as this as their cpus are 80+ to 125w, and have corresponding OC's of upto 200w+, although average is closer to 60-100w

Darkbreeze · Aug 17, 2014

Karadjgne :

Smart a@#, you know what I meant. Heh.

Darkbreeze · Aug 17, 2014

Karadjgne :

Gotcha, I might've just added something wrong in the calculator, which I know I shouldn't have been using anyhow as they're not accurate, but I was hurrying as usual with three things at once. I knew it seemed awfully high for that 50w processor and , anyhow, right on.
