AMD Phenom 9850 Power Query

[BrynS]

With the recent price cuts on the 9850 I'm thinking about bringing the internals of my ancient AGP desktop up to speed, but am a bit concerned about the CPU's power draw (125W) and whether my PSU will be sufficient.

The prospective system will be:

- AMD Phenom 9850 with stock cooling
- Gigabyte GA-MA78G-DS3H Motherboard
- 4GB RAM
- 1x ATI Radeon 4850 512MB
- 2x SATA HDD's
- 2x IDE Optical Drives
- 1x Expansion card (TV Card) & numerous 80mm fans
- Enermax EG465AX-VE (W) FCA 465W PSU

I won't be looking to overclock the 9850 at present, but may do so in future. Basically, is my current PSU likely to cope with this new setup?

Cheers,

BrynS

465w should be just about ok I think. THey are usually rated slightly under what the can actually put out.

Ok, thanks.

Just had a look in the PSU manual and this is it's load range, but I don't how this would fare on the above system:

DC Output Load Current Range

DC O/P Load / Max / Min
+3.3V (Amps) / 35A / 0.3A
+5V (Amps) / 35A / 0.3A
+12V (Amps) / 33A / 1.5A
-5V (Amps) / 1A / 0A
-12V (Amps) / 1A / 0A
+5 VSB (Amps) / 2.2A / 0.1A

-Max continuous total DC output power shall not exceed 460W.
-Max combined output on +5V & +3.3V shall not exceed 200W.
-Intel ATX 2.03 / ATX 12V Ver 1.2 Compatible.

You'll be flying close to the wind really but I reckon you'll be alright.

well my system doesn't get near 400w under load and im powering a 2900 and more hardware than OP.. so i'd say you'll be fine..

 

[BrynS]

Thanks for the help, guys.

Using Antecs PSU calculator it come's up with an approx system load of 361Watts so your current psu should be up to the task

Hello Mate,

Although Your PSU should be ok I'm afraid so say that I don't think that motherboard supports the 9850 Black

I think it requires more power (4 phase?) than the motherboard can provide?

Its also on the gigabyte site as not supported

Sorry to be bringing bad news! I hope you have not purchased / ordered yet!

but the 9850 uses the same power (125w) as the 9750 which is supported. only differents is the HT and core speed.
