powersupply size for AMD 3500+ ?

[Wayne Fulton]

Not an Asus question, but I am planning for a new Asus A8V board.

Is any special powersupply size needed for a AMD64 3500+ cpu ?

Most cabinets seem to have 300 or 350 watt powersupplies, so I assume
that still works. Specifically, I'm considering a new Antec True380 psu
(380 watts), with ratings of
+5V 35 amps max
+12V 24 amps max
3.3V 28 amps max

That seems like a lot, but I have no clue about actual requirements.
The computer will also have 1GB memory and 80 and 120 GB hard disk
drives. Any other ideas? Thanks.

You can never have enough power...............
I just bought an Enermax CoolerGiant430W for $89.00 to replace an ailing 350W
whatever
This thing has
SANYO DENKI blower inside: Unique 8cm blower directly exhausts heat from CPU,
RAM, chipset, and graphic card to enhance system cooling effect.

Smart fan: After PC shuts down, cooling fans keep running for at least 2 minutes
to effectively cool down parts and hardwares inside PSU and PC cases. Thus,
ensure longer product life time of power supply and hardwares inside PC case.

Separate 12V rails: Independent 12V rails supply to MB/CPU and drives in order
to provide stable and clean current to noise-sensitive devices, such as: CPU,
add-on cards.Meet UL 240VA safety requirements

ATX 12V V1.3 compatible: Support latest P4 and Athlon 64 platforms. For P4
platforms use 865 (Springdale) & 875 (Canterwood) chipsets and even new P4
Prescott and AMD Athlon 64 or later CPU.

S-ATA connectors: Connect your system to the faster S-ATA interface for better
performance.

Manual and automatic fan speed control: 8cm & 9cm fans automatically controlled
by thermostat plus rheostat control over 8cm fan. Enable users to keep the
balance between cooling effect and acoustic noise.

Extra Power connector: Extra 4-pin power connector provides high-end graphic
card with stable current.

Reliability: OCP, UVP, OVP, OLP, OTP, and SCP circuits ensure system
well-guarded from any dangers. Maximize safety for your hardware and valuable
data.

Copper-shielding: Effectively reduces electro-magnetic interference that might
affect MB and CPU from normal operation. (Valid for models with 370W and higher
total power)

Even with 2fans and a blower the damn thing is quieter than my old 2fan 350w

I got the same one, very impressive.

I just replaced a 400W Zalman power supply with a 500W Athena Power one
and my CPU temperature dropped over 10 degrees. I am running a Prescott
3.4 GHz CPU and it was running over 60 degrees idling and I was having a
lot of problems with the video disappearing until I rebooted. I have
had no problems with the video and the temperatures have dropped
noticeably with the new power supply. The 400W power supply was very
hot to the touch even though I had had no problems with it with my
previous setup. Maybe it couldn't handle one of the loads of the new setup.

I have assembled a PC last week.
AMD64 3500+, 1 GB RAM, two HD's.
I use a CoolerMaster PSU, 450 Watts.
This PSU is equipped with a power meter that can be fitted in the
front of the PC. So I did.
It shows that the system uses 100 Watts.
And "Cool 'n Quite" isn't even switched on (A8V Asus).

This might help you as a guide, but remember these are maximum possible
wattages for each device, and as such it is unlikely you would ever achive
them.

Thanks wazza. I also since found this powersupply calculator, at
http://takaman.jp/D/?english
It shows more up-to-date equipment, in that it shows the 90 watts for CPU,
and PS3200 memory, etc.

However it seems to show large wattage numbers for drives, Western Digital
says 10 watts running, but this shows nearly 30 watts, maybe that is startup
current. Even so, my total there is 272 watts, so I'm thinking a 380 watt
psu is adequate, assuming it is a good brand that can actually do it.

I'm just not very sure of myself, but my rationalization is also that I have
used a AMD 1.1GHz for 4 years on a 350 watt psu, and since the 3500+
consumes 30 additional watts, then that's 380w. I have no problem with a
larger psu, but this is the one that comes in the cabinet I want.

Sounds like 400 would be safe then.

Thats a nice Power calculation site.However when you punched your devices in did
you change the utilization % ?? Did you allow for future expansion??
That 350w I had on mine was good when I purchased but since then I have added
another HD,A TV card,changed from a DVP player to 2 DVD recorders.....and god
knows what I"ll add to the system right after Xmas.
Allow room for expansion that 380 w Antec or ? most likely is only $20.00 less
than that 450W unit.
The latest PSU reviews I read(found it by Google and deleted it since I bought
one) actually had the new OCZ Powerstream 420 as #1,the EnermaxCoolergiant EG
435VHB as #2 and the Antec (a modular unit) as #3.
There are many more out there and they come in various styles and sizes.....just
be sure you buy a good one.Stay away from the lightweight cheapies and you'll be
fine.

I saw a similar psu review at AnandTech, at
http://www.anandtech.com/casecooling/showdoc.aspx?i=1774 which rated the
Antec TruePower very well, saying "Overall, the Antec TruePower provided the
best all around performance. Feature-wise, it could not compete with the
Enermax EG465 or the Vantec Stealth Aluminum, but the performance benchmark
showed it has a slight edge over the other units."

I wasnt sure what additional features a powersupply needed other than
performance. What intrigues me however, other than quality, is that the
TruePower can control other case fans too.

Thanks to all posting the success stories, that makes it pretty clear.
The case I wanted has this supply, and I'm now convinced that 380 watts is
obviously more than enough for me. I suspect psu quality is a bigger factor
than ratings.

Actually, I just pulled the TruePower 380s out of my Antec Sonata case and
replaced it with a Neo 480. I was having crashes during intense graphic
gaming.

It hasn't crashed since, but unfortunately I did a LOT of other
been-on-the-list changes at the same time so I can't be sure exactly what
fixed it.

If you want features and performance, look at the Neo 480.
