Athlon 64 Power Supply Requirments

[EglsFly]

What are the power supply requirements for the Athlon 64 series of chips? (not including system components, just CPU)
12V rail amps?

 

[Concillian]

Basically anything adequate for a Prescott P4 is more than enough for an Athlon64. A64 max design power is 89W, which is ~8amps if it's coming exclusively from the 12v. A 6800 level video card will pull another ~6 amps or so (under load) from the 12v + other stuff you could probably get by on 15-17 amps if you needed to, but the trend is towards more 12v and less 3.3/5v, look for 20+

Problem I am having is that when I do a shutdown from windows xp, and after the system is off, I press the start button and it cannot find the hard drive. If I pull the plug on the PS so that the standby power is completely removed and power up, then it will come up.

Maybe I might need to get a better power supply?
Currently it has a Antec True 380W, the 12V is rated at 18A.
This might be too borderline.

System has:
Athlon 64 3800+
Radeon X800 Pro
DVD/CDRW
Samsung SATA 160GB HD
120mm FAN
Asus A8V Deluxe MB
2x512MB PC3200 Kingston Hyper X DDR
SB Audigy 2 ZS
56K Modem

If you think I need a better PS, do you have any recommendations on a Brand & Model PS?

Do you have that system now and are having a problem ? 380 Antec should be fine.

A enermax 350 has more power than trues. Run 3dmark2003...if it crashes or reboots you need a new PSU, perferably one with a 26A+ 12V rail. Enermax, Zippy and OCZ are all great places to start looking.

Newegg has an:
"ENERMAX Noisetaker Series 470W Power Supply, ATX 12V V1.3 compatible: Support latest P4 and Athlon 64 platforms, Model "EG475P-VE-SFMA"
http://www.newegg.com/app/View...=17-103-446&depa=1
This has Dual 12v rails, rated at 16A and 15A respectively.

Would this be better than a PS with 33A on 12V such as this Enermax:

?

i'm not a fan of dual 12's only because I have so much invested in single 12 with rock solidness and have seen no reviews touting any benefit.

I have the active PFC version of second one in your post but it's really overkill. This is all anyone but the most extreme overclcoker should need:

Bah it's only $15 more though might as well.
