Looking for a modular psu to power

1 290 (with enough room to upgrade to crossfire at some point)
8320 @ 4.5
8gb ram

Looking for something reasonably priced...

£60 - £80 if possible!

Cheers
 
A PSU capable of Crossfire 290s and a 8320 does not exist for £80 (well, a safe PSU doesnt exist at that price). I have a similar setup with a 290x and 8350, paired with a 1000w Superflower gold, in case i get lucky and another 290x comes my way.

For a single card i would be looking at this to stay in budget:

For a single card and modular, one of these two depending on if you can stretch the cash:

Before my Superflower, i used a 750w Fatal1ty OCZ PSU, which had half decent internals compare to their other range, but once the hefty overclcoks came on, i would trigger the current protections with just one 290x.

The Superflower Leadex Gold, Fully modular 1000w, which is what you would want for Crossfire, is at the £149 mark and comes with 5 year warranty.
 
If it'll cost that that's what I will have to spend, do you have any other recommendations?

Also looking for some ram for overclocking 8320...

Cheers!
 
AM3+ CPUs clock easier with decent RAM when aiming for top clocks, as you will get less memory errors.

I would probably grab something like this: http://www.overclockers.co.uk/showproduct.php?prodid=MY-032-TG&groupid=701&catid=8&subcat=1387

Then when it comes to clocking, reduce the RAM multiplier to the lowest and go up in CPU bus until you reach the CPU overclock you are after, adjusting voltages accordingly (you can throw the RAM voltage on 1.65 straight off and remember, more cpu/nb voltage is required for some of the high bus clocks but too much will cause instability as much as too little). Then change the RAM multiplier to the highest it can go without going too far over its original speed (2400Mhz in this case). Check if it is stable, if not, you can risk either upping RAM voltage (not much to be gained after 1.65 imo), loosening RAM timings, lowering RAM multiplier or lowering the CPU bus clock, until you find it stable with a half decent RAM speed (even if it is lower than the 2400 at cas10 like it is at stock).

After you got that far, just some fine tuning to get the most out of your CPU/RAM. Play with timings to see if you can tighten them. I would prefer much tighter timings at 1600 or 1866 on these chips over loose 2400/2666 timings. The CPU clock can normally go a fair bit higher with a mixture of multiplier and bus clock by reducing your bus clock a bit after finding its max bus only overclock and then upping the multiplier. Reducing bus clock will also reduce RAM speed and make it more stable/slower, you can choose to do this to gain stability while maximising CPU clock or use this to lower the RAM speed so that the multiplier can be increased on the RAM to closer reach the original stock speed of the RAM, if it has fallen short or even gain a higher speed if your RAM and chip allows for it.

This is just how i normally do things, i am sure a few people out there have different and better methods but this is what i use to clock CPU and RAM together for fx chips. I'll admit now, that i am far from an expert :).

Patience is the key to finding the perfect clock.

The PSU OverKill has specced is the one i use and is a monster PSU, my top recommendation for a heavily overclocked 290 Crossfire, 8320 rig.

I've sold 4gb of it with the my pc and I'm sending the rest back. The only reason I'm finally upgrading is because I discovered that one of the RAM slots on my motherboard was broken, that paired with the inability to use SSDs was the final straw.
 
Am I pretty much just looking for anything of a repetable brand that offers 2400 ram? I've found a few.

I also read on Linus Techtips that (within reason) ram speed doesn't equate to all that much and that it only really depends on the ammount you have, how true would you see this to be in terms of overclocking? Would having faster ram automatically mean I find it easier

Also found a 1000w bequiet psu for £135, how are those?

Cheers

I'm using the K2 mount doom. I saw that deal on ram earlier.

I could in theory mount one fan towards the exhaust but I'm concerned it'll make my cpu run hotter.
 
you could try having the fan on the back blowing air towards the back case fan which sucks it out of the case and have the fan in the middle sucking in air, basically push and pull configuration if your sure that high ram will fit
 
will the edge of the cooler still not overhang the slot(s) even without the fan on? looks like it could do
ive never cancelled an order, have a look in your account section on the website
 
yeh but the space between the ram sticks and where the cooler go are different on each board, i would just go for the low profile team group i linked
 
While I'm here I might get some thermal paste rather than the supplied stuff, whats good?

Also thinking about a mechanical keyboard but have no idea what I'm looking at...

cheers!

I ordered the lowprofile ram earlier along with the superflower psu.

this is what i use, its good cheap and theres enough for 1 use in the packet :)

YOUR BASKET
1 x Prolimatech PK-1 Nano Thermal Compound (1g) £1.99
Total : £4.27 (includes shipping : £1.90).

 
I'm assumming I'll get the same stuff with the cooler. Is it worth spending money on arctic silver anymore?

ignore me, I thought the k2 was made by prolimatech...
