Well you have not stated what components this PSU is going to have to drive, but if it is the system in your My System plus a HD or two and an optical drive - then it will be fine....
Try to make each and every day the best it can be.
it'll be:
*36GB raptor (SATA)
*200GB seagate barracuda (SATA)
*2 x optical drives (ATA)
*Leadtek PX8800GTS 640MB GDDR3 PCI-E
*Asus P5N-E SLI NF650i SLi, S 775, PCI-E (x16), DDR2 533/667/800
*Intel Core 2 Duo E6400, Socket 775, 2.13 GHz, 1066MHz FSB
*2GB (2x1GB) CorsairTwinX XMS2, DDR2 PC2-6400 (800)
*Lian Li pc1000 case (2 x 120mm fans)
*Zalman CNPS9500-AT Intel LGA775 Aero Flower Cooler
What do you reckon?
Search for PSU Power calculators on google.
If your going to SLi the cards, I'd strongly advise something above 500w. But you might get away with 460, but it will be very close.
"my system" calculates to 476 I think..with overclocks.
And yours will be more greedy than mine as I only have one HD and one DVD atm.
Get a new one.
No dont...they arent very good and i havent found any that are within 10% of requirements.Search for PSU Power calculators on google.
What are the 12V rails on this PSU? The Asaka PSUs are pretty decent ya know

Ladies and Gentlemen. The PSU is the ONE item you are MOST likely to keep from one system to the next, for year after year, and it's the one thing that may let you down and keep you searching for weeks for a faulty component that doesn't exist if you get one to low/cheap.
In 1 years time, when the Hard drives are running full, when you'r on a new vid card, maybe two, and you'r thinking Quad core or new mobo etc etc....
it'll be the PSU that you spend so much money on last time, that stays with you.
In short (rare from me, I know)......
/giggling from the back
In short.....spend MORE money on s PSU and less on the vid card or cpu becaue you KNOW it's common sense, in the end.
I thank you.
quite difficult to spend more on a PSU than the high end components he's looking at but I do agree with what you're saying..spending about £100 on them can be hard but its worth it in the end.
yup...my bad wordings..typical speech from me really. Lucky I'm sober
I mean take money AWAY from CPU/Vid budget and add to PSU budget.
Next thing NOT to save money on, is RAM. Get a proper brand.
My view on that PSU with this system configuration is NO!
You are contemplating using a low cost PSU on a high-end (and high total cost) system. False economy.
The PSU is one of the most important components in your system, it supplies "fuel" to power you computer and must be reliable and stable under load. Your PSU may be with you through several builds and upgrades.
I suggest a Seasonic S12-650 Energy+ other will suggest others, but quality is paramount.
Try to make each and every day the best it can be.
If you're thinking about overclocking or future proofing (going quad core) then don't even think about skimping on the PSU, in my experience alot of system instabilities/faults are derived from under specified/inadequate PSU's.
Just because a system runs using a certain PSU dosen't mean it'll be that way 1-2years down the line or that it'll be stable, running a system that requires 470watts on a 470watt/500watt PSU is a no no. Although it'll run, your pushing the PSU at 90%+ load and will mean the components wearing down quicker/overheating in the PSU. When a PSU dies it 'can' take down various components with it, so when buying a PSU overspecify buy a PSU with slightly more wattage than you require.
Another thing to remember is wattage is not everything, but also quality will play a large part in the PSU's performance, only buy name brands, high efficiency units also look out for over voltage protection, over current protection, and short circuit protection, etc to protect your components.
I would say a 10-20% of your overall system budget should be spent on your PSU.

bumped by me, cos getting the right PSU is the best thing a PC person can do...and this thread is good
How much is the Zalman you're (or were) thinking of buying?
I'd also have a double think about the Zalman cooler, plenty of other coolers around that are better, quiet and maybe even cheaper.
Oops - bought this one on the 20th march - how are scan on returns?
460W Zalman ZM460B-APS Noiseless SLi ATX Ver. 2.2 / ATX12V Ver. 2.01, 20+4Pin EPS 12v
Scan code LN13598
£49.00 Ex VAT
£57.58 Inc VAT
Usually very good but post a thread on the Scan forum and ask 'cause it's not actually faulty.
