Anyway back to the server, if I were to buy a Seasonic for this one, what would you recommend? The X-650 looks lovely, but not spending £150 on a PSU for a PC that barely needs half that much wattage

Seasonic Platinum only goes to 660, on gold there was the X560 that was also a superb psu, but i believe it has been discontinued.samuelmorris wrote:It is a little spendy, I'm just thinking, is there not a 500-550W equivalent to either of those units?

To keep down costs you could consider a deal currently available from Scan. This is the Corsair AX750 Gold 750W for £74, the price reflects that it is factory refurbished. It is closely based on the Seasonic Gold units. (I think it was manufactured by Seasonic to Corsair specs, the build quality is just as good but there are differences such as flat ribbon type cables).samuelmorris wrote:It is a little spendy, I'm just thinking...

It's too much expensive at 90.samuelmorris wrote:Sorry, can you clarify 'doesn't worth that much' for me? Is that good or bad?
Yes, spin-up current can easily push power draw to 3x the typical/seek level, but only for well under a second. I think it's the initial torque required to accelerate the platters to full speed, so drives with more platters will pull more power. It's not clear how high peak power of this nature would impact PSU logevity; certainly good ones will easily handle more than rated power for such short durations, but what's the impact of thousands of such overloads? OTOH, yours will be a 24/7 machine, so fewer startups, which makes it a trivial issue.samuelmorris wrote:CA_Steve: Point well raised, yes it's basically the UK version of the Kill-a-Watt measuring AC draw.
Correct me if I'm wrong here, but is it not the actual process of spooling up the disk platters to the 5400rpm speed that prompts the highest draw, instead of the buzz routine? If that is the case, the drives should take long enough to spin up to get an accurate reading.
Having tested switching high-current devices on the kil-a-watt it only takes a couple of seconds to stabilise a reading, and WD green drives (by spec, and also listening closely) take around 7 seconds to spin up. I was seeing several fairly consistent readings come out before the power usage dropped as the disks were up to speed.
Please, don't get me wrong, the RM-series is a fine, no-hassle choice, and I've already gave you my input about it, for what it worths (either the RM550 or the RM750).samuelmorris wrote:but if I'm not going to find anything better for that money, or something equivalent for less money, then what of it?
