Advice on PSU upgrade

c28omzk7ihsxv0

Okay, I'm considering upgrading for xmas...
so currently I am running:
CPU: AMD FX-6300 (stock fan)
RAM: 8GB Ripjaws
Mainboard: ASRock 970
GPU: AMD 7850 w/1024mb
HDD: WD caviar Blue 1TB
PSU: Super flower Amazon 80plus 450W

I also have a Basic Cd drive, two case fans, a multi card reader and a case HDD docking station (I'm just including these in case any (or the combination of them) significant amount of power)

I would like to buy another 7850 and crossfire it, throw in another HDD and maybe another stick of RAM.

I was wondering if I would need a higher power PSU and if so could ye wizards recommend me one that isn't too expensive and would suit my needs.

Thanks for the help

Whats the full model of the motherboard? Needs to have crossfire support. If your only using the PC for gaming then you don't need more than 8GB of Ram and you will not see any difference. Most games are can only use a max of 3.5GB of Ram these days.

I want the ram for several programs (which I often have on at the same time) such as Autodesk/Auto Cad, photoshop etc.

It is an ASRock 970 Extreme3 (AM3+) (ATX)
(which to my knowledge has quad crossfire support)

I use this with my crossfire system and find it great. Recommended quite a bit on here. http://www.hardwareversand.de/600+-+700+Watts/74175/be+quiet!+SYSTEM+POWER+7+700W+-+bulk+-.article

Here's the one I use http://www.amazon.co.uk/Thermaltake-Smart-Series-80plus-Supply/dp/B0079RFCPA/ref=sr_1_1?ie=UTF8&qid=1384113276&sr=8-1&keywords=thermaltake+psu+850w

The be quiet one is a good PSU check reviews if you fancy.. Cost around 80. The other is very expensive and slight overkill for crossfire on the cards mentioned.

That's more like €100 with delivery the Thermaltake 850w I use is an extra €20 and it's modular so for €120 it's actually not a bad price at all plus there's more head room for future upgraded gpu crossfire set ups etc.

Thanks guys, ye wouldn;t be able to recommend anything slightly cheaper though (such as: http://www.hardwareversand.de/600+-+700+Watts/29234/Super-Flower+SF700A14A+Gamer+Edition+700W.article )

I'm trying to keep costs minimal so I can afford the other parts :P

Don't buy a psu that isn't 80+ rated, it's one of the most important parts in your pc so if I were you I'd spend that bit extra and get something decent, cheap psu's can destroy your system so there not worth the risk imo.

Here's a decent one at a good price it's modular too works out with shipping at €80 http://www.komplett.ie/komplett/product/zkb-01com/80012791/coolermaster-gm-series-g650m-650-watt/details.aspx
