Enermax Pro82+, 385W Scan Link £41

The 88% efficiency of the Enermax probably makes it worth the extra pounds over the Corsair but if you looking for cheap then the Silverstone could be just the thing and still have >80% efficiency.

Would 385w - well 338.8@88% - be enough to run this system?
I'm thinking of running

• x2 4850e
• 780G (Mobo+gfx)
• 2gb ddr2 ram
• 74gb raptor
• 8x 1tb WD "Green" HDs (4 raid 1 arrays)
• 4 or 5 case fans

£41 for an efficient PSU seems like a good price... I wonder if it would support what I'm thinking of??

Have you looked at the general running costs of this? I can no longer run my home server due to the cost of Electricity these days 2.5TB on that as well!

Yes, come on solar power, we need you to mature today or sooner!!

that should be more than enough baius, but why are you going to be running 4 mirrored arrays? why not use something like RAID6, giving you 6TB instead of 4?

385W is the maximum power that (in theory) can be delivered out of the PSU into your PC. At 88% efficiency that would mean that 385 * 100/88 = 438W being drawn from the wall.

In practice, I wouldn't expect either of your options to draw more than 200W from the PSU.

Sorry to take so long to reply. As explained elsewhere, emails crowded the topic notifications.

Thanks for your comments. This might be a good PSU then.

I'd heard that Raid 5 could be tempermental, especially in software. I prefer the idea of having drives over Raid 1, and "swapping" out a hard drive each week, and storing elsewhere, (and letting my raid card rebuild the remaining full hard drive with the freshly inserted one).

That might not make much sense - it does in my head though...

I probably don't need four raid 1's though. Bit greedy. Might want 2 though.
