Which PSU would be best?

[Benzz]

Hi,

Recently my PSU has thrown out a 3.3v warning ranging from 2.944 to 3.120 max.

had to spend a good bit lately which has left my machine on a budget but good PSU,

spec to consider:

Thermaltake Armor+ Case
i7 2600k processor
Corsair H80 Cooling
ASUS p8z68 pro board
2 X 4GB corsair Vengeance RAM
2 X 1gb Sapphire Radeon 4800 1GB on crossfire
1 X OCZ Agility 120GB Sata
1X Samsung 500GB 7200rpm Sata
1 X 1TB WD green sata
1 X liteon DVD RW drive

I am thinking of getting the "OCZ ModXStream Pro 700w" would this be recommended or has anyone else got some suggestions? bearing in mind I would need minimum 4 Sata power, and 2 lots of power for GPU.

Thanks

** missed information: Currently on Jeantech STORM 700w psu which has the fault, the cheapest i've seen which I think will be best is the OCZ ModXStream 700W at £64.99

my question is, is there a cheaper and still reliable psu for my systems requirements?

The OCZ ModXstream Pro 700W is a decent PSU and is sufficient for your system. It is actually overkill for your system. A system with a Core2Duo E8400 used 421W at full load. A good 550-650W PSU is actually sufficient to run your system. Two of the better options are the XFX Core 550W and 650W:
1. 550W: http://www.scan.co.uk/products/550w-xfx-pro-series-core-edition-p1-550s-ukb9-85-eff-80-plus-bronze-sli-crossfire-eps-12v-fan-atx-v2
2. 650W: http://www.scan.co.uk/products/650w-xfx-pro-series-core-edition-p1-650s-ukb9-85-eff-80-plus-bronze-sli-crossfire-eps-12v-fan-atx-v2

The 550W is alectrically sufficient, but will likely run hotter at full loads because it will be operating around 80% of capacity; that would result in higher noise levels as the fans speeds up. I'd go with the 650W to reduce noise at high loads...both have sufficient PCI power connectors.

If the OCZ ModXstream is less expensive than the XFX Core 650w, then I would consider it as an option, butI would still lean towards the XFX; more warranty and is a better product that is made by Seasonic for XFX.
