Hi all, I'm possibly going to be grabbing a few bits to play with in the next month or so and wanted to check with the PSU experts out there if the Coolermaster Silent Pro M 700W would be enough to power the following parts: i5 2400 (clocked to 3.6GHz) 8GB DDR3 7-8-7-24 (2x4GB) 2x 560Ti 1GB OR 1x 580 1.5GB 4x 1TB HDDs 7,200rpm, 1x 80GB SSD 1x Optical DVD-RW Any thoughts on whether 700w is enough, or do I need to get a little more?
I'd probably say bump it up a bit if possible, although 700W may be just about fine. Maybe a corsair AX850? Sent from my HTC Desire using Tapatalk
as long as its a decent power supply with the correct amps on the 12v rail or rails for the graphics card you should easily be able to power that lot whether its the 2 x 560's or a 580 edit: oh and just a point assuming you haven't already purchased the gpu's I would go with the single 580
The AX850 is a little pricey at nearly £150. So far from the reviews I've read, the Silent Pro power supply has give pretty good results for the 12v Rail.
An entire system with 2x GTX560 Ti draws 450W from the wall when the GPU is stressed (source: guru3d) so 700W is overkill... like most PSUs we see in sig rigs (mine included, however it was used for GTX470 SLI for about a day ). These big PSUs sell because they are cleverly marketed - they make us think we need them, but we really don't. I'd go back to my 500W Silver Power if I hadn't voided the warranty on my Toughpower.
The reason I always go for a PSU way over what I need is PSU's rated output drops over time, so in a couple of years when you buy that new power hungry GPU it may go pop. Also I've found the big boys are way way quieter than smaller units, even if they're 'silent' units, as the big units will never heat up enough for the fan to need to spin up...
Slightly off topic, but just so you're aware, the 2400 cannot be overclocked. You'd need a 2500k or 2600k if you want to overclock. TSB
Good point, but definitely not always the case - I had to swap the 140mm fan in my Toughpower because even on low speed it was too noisy for my liking. But like I said you do make a good point; higher rated PSUs in lower systems don't work very hard at all and don't require significant airflow to keep them cool.
Thanks for the feedback everyone, I might think about dropping the wattage slightly then and going for the ever so trusty Be Quiet 680W. Also thanks TheStockBroker for the heads up on not being able to overclock the 2400, I might switch that for a 2500k then. I shouldn't really need to push the clock up, but it's always fun to do.
A 700w is more than enough. I'm currently sitting at 4.4 with my i7-2600k along with an OC'd GTX 580 on a Seasonic X-650. I would recommend checking out the new Corsair TX650 v2 - http://www.ebuyer.com/product/257232?utm_source=google&utm_medium=products It's amazing value, whilst kept under that quality Corsair brand.
im still usiing my tagan 480watt lol after several upgrades now running a phenom 2 x6 1055t 140watt version ati 5770 hd heavily overclocked to 1000mhz 4 gb of ram 1 x 64gb ssd 2 x 1tb hd's just about to add another 5770 or upgrade to tri 5850's not made up my mind p.s. after 5 years of loyal service the only reason im upgrading is because i need more power maybe a 700watt will cut it anyways your 700watts sounds about right
