Will this PC build work, or die? Need PSU and ventilation advice

i have an:
i3-4130 - 3.4ghz/2 core 4 threads - 54watt - with stock fan

Sapphire duel-x R7 265 2gd5 - 150 watt TDP - 6 PIN 75WATT PCI-e REQUIRED!

Optical drive - standard dvd player/with RW

1 hard drive - 1TB

AMD A75 FCH chipset. It's a motherboard and i couldn't find a lot of information about it.

USB 3.0 x 2- USB 2.0 x 4

standard 1x 8gb ddr3 ram

I need a psu, one that is 15W, 8.5H and 14L. i live in the uk, so a 3 pin plug is imperative.
Something bronze 80+ will do. The websites says a 500w psu is required.

If i go over to amazon and buy a corsair CXM 500W, will that be fine, or can i find better? nothing over £50, that's all i have.

Now the only issue remaining is ventilation. this is why i'm preferably going with a semi modular psu. The case is a rather small hp pavilion 500-123ea with a 3 small mesh parts on one side (10.5cm x 10.5cm / 4.5cmx10cm / 3cmx3cm). Theres a very quiet, 11cm x 11cm fan on the back, producing cool air if i hold my hand over it. The fan appears to be brand-less, other than a foxconn sticker, covered by the case's metal safe guard and a few tears.

Computer here,
scroll down a bit on the link -http://www.ebay.co.uk/itm/HP-Pavilion-500-123ea-Desktop... 252BPlhirI%253D&orig_cvip=true&rt=nc&_trksid=p2047 675.l2557

Sorry for rambling. If anyone made it to the bottom. cheers, ily, please help me.

I'm pretty sure a CXM 500W should be fine although I wouldn't personally get a power supply from the CX line of power supplies.

I see. i looked around and found this Seasonic S12II-520 520W ATX12V Standard Power Supply Unit- Bronze. Will this do?

Both the Corsair and the Seasonic will power your system fine, but unless you have more room for the PSU than your description lists, neither will fit in the case. They're both about 2.5cm too long.

The only quality PSUs that I'm aware of that will fit those dimensions are the Silverstone Strider series. They're 15 x 8.6 x 14. Are the dimensions you listed the actual dimensions of your current PSU or the space available? Or both?

The Silverstone SST-ST40F-ES will power your system and meets your price limit (34), but is non-modular. The next one up that I found listed for the U.K. is the SST-ST65-G, which is more than you need and costs too much (88), but is fully modular. If you really want to go over budget, you can get the optional short cable set for the ST65. You'll have to check and see if the extra mm of height is a deal breaker.

I'll have to do a little more research to see what your fan options are, if any. With that GPU you're probably going to want something more than a single small exhaust fan. Are any of the mesh areas opposite the GPU slot by chance?

i got the seasonic s12, it is 15w 8.6h 14l in cm, so it fits.

if this is my case the gpu will face downwards (the motherboard is screwed to the side). There isn't any mesh on the bottom of my case (which wouldn't help) but the would be mesh a little under (where the air is being blown by gpu), to the side. if you can visualize that. there is a fan at the bottom, on the back of the case air will be blown in that direction too. Gpu will be around 4-5cm away from the fan/mesh.

Apologies - I must have looked at the wrong model when I pulled up the specs. It appears no harm done though since you've already got the Seasonic and it fits. If there is a king of PSUs, SeaSonic is probably it - you should be very happy with the performance. I'm glad you enlightened me as I've been looking for a short PSU myself and thought I was stuck with a Silverstone. Not that they're bad, but I'd rather have a SeaSonic myself.

I'm assuming that you have the system up and running? If so, how do the temps look? I've looked at some pics I found online but haven't found any that show the internal layout. From your description, it sounds like there's a good chance that the GPU will be able to vent at least some of its heat directly (or almost directly) out the side. Is the mesh on the removable side panel or the same side as the mobo? From the pictures, the mesh is on the right side as you're looking at the front of the case - normally that's the side the mobo mounts on.

hello volcano. I do not have the gpu yet, it's at the post office right now so i'll get it tomorrow and i'll message you then or the next day regarding the temperature. In my room where i'll be playing on the computer, the door and windows are always open, so i assume it'll be fine. If not, then i'll keep a fire extinguisher close by

the seasonic s12 i got from amazon at £55 reduced from £72, did come with a eu plug (the one with two pins). but i assume i can use the old psu plug cable as it's the same shape going into the psu, and it's the same power (10am 250volts) (uk plug)

Should work, but you may want to test it before you plug it into your mobo. Do you know how to do the PSU testing trick with a paper clip and fan?

it's finally done! gpu looks and runs brilliantly.
I'm currently playing tomb Raider at higher ish with x4 AA. Psu gives off quite a bit of heat from the back/ fan at bottom is cold
/everything else is fine.
Psu is fab, but it doesn't have a fan at the back pushing air out of the case (my old one did), shouldn't be a problem though. There is alot of room at the front for the cables. the wire casing is thick, the abundance of cabling could be a air flow hazard.

My main concern is overheating, the gpu goes in upside down, so the gpu fans are opposite the psu fan, which i assume if they are both pushing air towards eachother, it'll cause friction. they are around 5cm away from eachother.

i ran valley benchmark: on ultra all effects on it was around 20 fps (very stable), but the heat rose to around 62 degrees celcius before i quickly turned it off. it's around 35 when i'm not doing anything demanding.

My thoughts:
-removing cd drive for more room for cabling
-sending back seasonic for semi modular version
-buying a better heatsink cpu fan or fan at the bottom of the back of the case

i do have a micro tower case if worst comes to worst i could replace with a tower (or more heat efficient micro tower) and just transfer my current components over

62 isn't bad, especially for that case - if it goes into the 80s and stays there, you'll want to make some adjustments. The big fan on the PSU should be the intake fan, not the exhaust - the exhaust should still be coming out the back. The fans on the GPU are intake also, so instead of blowing at each other, they're sucking air from the same area and pushing it in opposite directions. Set up the way it is, it should actually be helping your case temps as it will suck some of the hot air from the GPU and kicking it out the back, as long as neither is starving the other of cool air. Does your case allow you to mount the PSU fan down (i.e. is there a grill or vent in the case bottom underneath the PSU)? If so, try flipping it and seeing what your temps do.

I'd take a look at your settings - I'm thinking your FPS on heaven should be closer to 30. I wouldn't think your CPU is bottlenecking you. Now that I think about it, was the 62C for your CPU or for the GPU?

I would seriously consider getting a good mid-tower if you've got the space for it. Even a cheap one would give you much better airflow, more room inside to work in, and much greater options for components.

apparently Valley Benchmark is used to stress gpu so the temperature is probably gpu (the test did take place after around an hour of youtube).
I'vw seen a few forum threads were people have said the cpu wouldn't bottle neck even more demanding gpus, like the r9 270x http://www.tomshardware.co.uk/answers/id-1974244/4130-b... (which was my initial preference).

I'm sure the heat will be fine. I ended up playing tomb raider for around 3-4 hours yesterday on high settings and it was fine.

I would love a larger case, but then i'd need a new psu and i'd have to transfer all the components over and i'd have to buy longer wires and i'd have to spend more money on the case (i know not too expensive).

I don't have a job ya see, but the thirst for hardware grows. i'm planning to leave this build as it is and i'll start a whole new one when i have the money and the confidence.
Thank you very much for your help

It certainly sounds like you're set for the moment. If you do scare up some spare change that isn't needed elsewhere, there are some very smart cases available starting at about 30 pounds, most of which come with fans included. Below that, I wouldn't bother as it probably wouldn't be much of an improvement. All of the components you've listed will transfer over, so you shouldn't need to make any additional purchases. The stock cables for your PSU will work also. Really, all you'd need to do is measure your mobo to determine whether it's ATX, micro ATX, or mini ITX, to make sure the case is compatible. (http://www.buildcomputers.net/motherboard-form-factors....)

Anyway, I'll leave you to it and good luck on the job front. Feel free to PM if you need any more assistance.
