Is this PSU sufficient

Hi,

Ideally I want this:- http://www.overclockers.co.uk/showproduct.php?prodid=CA-018-SS&groupid=701&catid=123&subcat=2383 but it's out of stock here and everywhere I look.

Which leads me to this which is in stock, and cheaper:- http://www.overclockers.co.uk/showproduct.php?prodid=CA-019-SS&groupid=701&catid=123&subcat=2383

Would the latter be enough to power:-

Stock 8350
VTX3D 7870 Tahiti LE again at stock speeds
3x HDD
1x SSD
H80
4 case fans (1 being on the H80)

Whilst it's my plan to under volt both the CPU/GPU, I should scope for the other end of the spectrum when both are over clocked just in case.

I don't plan to CF the 7870's (been there, done that) and if anything my future upgrade path would be to just get a single new card which will most likely benefit from a lower TDP anyway. I may be switching to Haswell in the next 3-6 months.

Thanks,
Chris.
 
I would rather see a PSU closer to 500-550W for that sort of spec maybe, but the Seasonic is a strong unit.

Also just noticed Antec have a Platinum rated 550W PSU listed at OcUK

Just spotted that! Quite a big price hike going from a 450W to 550W £26 seems a lot for 100W, otherwise I would have bought it straight away! I agree the 550W would give me a little more comfort however I think I am going to risk the 450W version of the Seasonic, as I know reading reviews these can typically hit 50W higher than spec (if required) reading reviews.

Currently underclocking and undervolting my 8350 to FX-8300 speeds so should have roughly 95 Watt use, Tahiti LE undervolted should similarly only pull around 200 Watts gaming, so add another 50W for everything and I believe I will be around the 350-400 under full load, obviously this is roughly 70-80% load which is not ideal but looking at the Seasonic it still produces very high efficiency at this rating and I have confidence in the high quality components. If I do go Haswell in the coming months then total use would be in the 300-350W region, and none of this would then be a concern.
