PSU question, good enough for 8800GT ?

Well I've changed my config a bit and have managed to save enough for an 8800GT 512 mb (only just enough), and just wanted to make sure the psu is good enough.

It's an Akasa powerplus 550W (630W peak) and it has 55 amps spread across 4 12 V lines, it's sli verified and has 2 native pci-e plugs. I've had it for about 18 months now it's been rock solid for now.

So will the psu be good enough for my specs when I buy 2 extra gigs of ram and an 8800GT and an extra hdd ( getting the ram & hdd for xmas)?

The spec's it'll have to power:

C2D E6400 @ 3.2ghz, perhaps oc-ed more in the future: not at it's limit yet.
Asus P5B deluxe.
Asus Geforce 8800GT 512mb ( sorry, but they are a lot cheaper here in some dutch retailers than anything ocuk has, hence I'm getting it above the (imo) overpriced bfg/evga/ocuk ones).
4x1 GB Geil ULL pc6400
2 IDE 7200 rpm hdd's, 4 Sata 7200 rpm hdd's, 2 sata DVD burners
Audigy SE
Pci IDE Siliconimage card
6 Usb stuff
5x 80mm fans


Do ya guys recon the power can still supply enough power for all above ?
And perhaps a bit of extra juice to OC the 8800GT, I really don't know how much power the 8800GT needs.


EDIT: it's voltage table :

OKAY thx :D.



Can't wait to go up 2 gens of gfx cards, 6800 to 8800, great change I think.
Feels like I have kept this card for ever.

Feeling glad I've bought a way too powerfull psu 18 months ago when I didn't really need one like this back then. just had a p4 @ 3.9 ghz and an 6600GT then lol. Also just 3 hdd's back then, now I'll have 6 soon :). No need to spend €€€ now on another psu ( bought this psu for 140 € iirc ages ago ) :D.

you got 450w available on the 12v rails, thats plenty for you system even if you were to run 2 of the 8800gt in sli.

Please take that with a big pinch of salt though since its nowhere that simple - you should be fine though...

What you have there is a very high-powered PSU.

You're not going to struggle running any hardware on that any time soon.

Not much salt required, his PSU would easily handle GTX SLI possibly even three of them. :p

Not really - those stats are only correct if all other rails are totally unloaded which wont happen in a normal system (i.e. at no point will that PSU provide 55amps on the 12V rails in his system) - I wish more people on these boards actually took that into consideration when reading PSU specs and given recommendations...

Check up on Power Load curves...

Been there, done that, got the tee-shirt and had experience with PSUs of very similar specs to his.

Trust me, I'm not just making this up. ;)

Then you would know having PSUs with very similar specs to his wouldnt give you the ability to really offer useful, informed advice unless you have had the same make/model as his since its very unlikely to have the same power load curve over multi-rail loads :p...

Unless his PSU is woefully inefficient, it's going to perform roughly the same.

Unless you'd like to show some evidence that his PSU won't handle a GT... Or even GT SLI. ;) :p
 
Lol, well reviews of the site ocuk has trouble with said it performed as it said and that it had rock solid lines.
Renmber tho this is a psu originally designed for servers, it's made for a 24/7 550w output while being capable of doing 630W for periods of time @ 50 C ( unlike brands like coolermaster, wich sell their psu's rated @ 500W because they have a peak of 500 W @ 20C.)
Other review sites wich had a less advanced review still were praising the psu saying it provided stable lines.

It has masses of conenctors, including native 8 pin power (splitable into 2x4pin) and additional spare 4 pin p4 plug, it has 9 molex, 4 sata, 2 pcie 6 pins, 24 pin ( splitable into 20 + 4) and 2 floppy's I believe. Been quite happy with the psu just shame it wasn't modular.

Never mind the psu anyhow, I've ordered my Asus 8800GT 512mb, due to arrive within 5 working days :D, can't wait haven't been exited in ages like this, I'll be jumping 2 years to the future in terms of game gfx :D.
