Right so I'm basing a build off the Enthusiast spec of August's guide. Spec Fractal Arc Midi I5 3570k Gigabyte Z77-D3H 8gb Corsair Vengeance 1600mhz 1tb Samsung Spinpoint F3 Arctic Cooling i30 Future additions Adding a 7850 or 7870. 60-64gb SSD (boot drive to start off with) Much further down the line a 120gb/256gb SSD depending on prices A second 1Tb harddrive at least. OC'ing Overclocking will be done on the 3570k to a mild 4-4.3ghz. Should I opt for the 7850 i'll be looking to overclock straight away and if (funds permitting) I choose the 7870 i'll most probably be looking to overclock it in the future. No plans for Crossfire as i'm not a big fan and it'd be wasted on that board anyway. Main Use Plan to do a fair amount of gaming well into the next few years with main interest in and around the FPS/TPS genre, occasionally straying to other genres but you get the picture. My dilemma Now as you can see i'm missing a PSU. I need help choosing which will be best suited for my needs, will be a strong performer for the next 3 years or so but also take into account a £90 budget. I know when it comes to PSU's you shouldn't skimp but I'm hoping there's a good PSU out there in the 650w bracket for £90 or less. The Choices I was considering the Corsair HX650 for £90 at overclockers.co.uk. Here http://www.overclockers.co.uk/showproduct.php?prodid=CA-022-CS Am I wrong in thinking this version of the HX650 is built by Seasonic? or is it the, i'm guessing, newer HX650's that retail at ~£100? OR Seasonic S12II 620w @ £76.34 from scan http://www.scan.co.uk/products/620w...i-620-87-eff-80-plus-bronze-quiet-fan-atx-psu OR Corsair Enthusiast TX650w V2 @ £70 from Scan http://www.scan.co.uk/products/650w...-bronze-sli-crossfire-eps-12v-quiet-fan-atx-v I've read mixed reviews about longevity. So anyone with any experience please let me know how it is. And from what i've gathered they're fairly loud underload but it's in the list since it's the cheapest. Any other suggestions are welcome. Noise won't bother me a great deal but nothing ridiculously so. If it's loud enough to be mentioned in product comments then it's probably too loud for me. Am I asking too much for £90? lol Well in any case any suggestions and ideas are welcome.
