I'm low on cash at the moment I'm limited to about £95 for a PSU and Graphics card but I've found a Radeon 7750 for £69.
Why won't it fit? Is it made to fit in Dell computers only or is it too big?
From what little i could find on that first PSU you linked its a EPS Server power supply also you note it has a extra bracket on it. You would have to remove that bracket and then extend some of the wires to make that fit into your case. Plus its used!! a server is on 24/7 for years.. PSU's have a normal life span. That thing is scary.
I'll check around and see what we can find that would fit your Case better.
the 149w-229w includes all the above hardware (including the video card) at idle and during gaming. at your budget, you won't get anything better then what is currently in your PC. if you want to save up for a budget (yet solid) PSU, i suggest the corsair 430w which can power newer cards like the AMD 7770.
Yeah, i can't find anything anywhere near 26 GBP that i wouldn't consider a fire hazard.
The CX430 is 36 GBP i would shop around your other PC stores and see if i couldn't find a better deal then Amazon thou. CX430 will last a good wile and power your system just fine. Also you are getting a great deal as Corsair sells these at cost, they make there money on the more pricey units in there line.
Also whats up with VAT (Value added Tax??) Dang thats a huge tax if that what it is.
