thanks for the replies i will check them both out, have i made a good choice on the case ? like i said its my first build so

Redmint · 24 Aug 2010 at 17:37

It's a nice case.

(Stulid's PSU suggestion will handle 2 in Crossfire, but if you really hammered the system in a stress test you'd be getting a little closer to the limits of the PSU than I generally prefer to go).

top case.

notorious19 · 24 Aug 2010 at 17:46

so really i shouldnt go for any psu under 650 is what your both saying right ?

stulid · 24 Aug 2010 at 17:48

yes, but the next questioning is what motherboard are you getting, got.

not all of them support crossfire, meaning you may not even need 650w

Redmint · 24 Aug 2010 at 17:50

You could get away with less if you never plan on going for Crossfire. However the Sapphire is a nice PSU for the money and under heavy load (gaming) it'll be running at about 50% usage, which is a nice figure for a PSU.

http://www.overclockers.co.uk/showproduct.php?prodid=CA-032-BQ&groupid=701&catid=123&subcat=1083 That one is a few quid less and also fine for a single 5870.

notorious19 · 24 Aug 2010 at 17:57

for motherboards i have beenn looking at the

Gigabyte GA-MA770-UD3 AMD 770 (Socket AM3/AM2+) PCI-Express DDR2 Motherboard [GA-MA770-UD3] and the

Asus M4A87TD Evo AMD 870 (Socket AM3) DDR3 Motherboard [90-MIBCK0-G0EAY0WZ]

stulid · 24 Aug 2010 at 17:59

both support single cards only.

and the usb3.0 version of the asus is the same price.

Redmint · 24 Aug 2010 at 18:00

Out of those 2 motherboards I'd suggest the 870.

+1 what he said (Redmint)

notorious19 · 25 Aug 2010 at 20:29

Asus M4A89GTD pro/usb3 ?

No!

You say price is an issue. There is much more to a psu than the claimed wattage. You can find 700w supplies for 20 quid, do not buy one of them.

I dont think you need a 650w supply myself, but its fashionable to over specify supplies. Ill vote for any 500W+ one with corsair written on it.

only if you want two ATI cards in crossfire, if you do, then this

is cheaper, same crossfire chipset and features.

I only buy corsair PSUs, they are very good, well worth the price. Do you really want to skimp on the device that controls the voltages & current provided to your new PC components? very cheap=inacurate voltages, worse over/under volt/current protection etc... I'm not neceserily saying that the above quoted PSUs are bad, I've never had an experience with them, but the non-branded £20 for 700W+ are bad, I've had experience with their smaller brothers (around the 400W range), and had lots of them blow on me, now running corsair, and it's been great for years.
