Will current PSU be enough?

I'm thinking of upgrading my system with a Chaintech nforce4 Ultra mobo, an athlon64 3000+, and a radeon x800xl pci-e card to go with my seagate 120gb sata, and 512x2 Geil pc3200 ram.

my question is, will my antec 380w PSU be able to power it all when I include my liteon cdrw, asus cdrom and 2 cooling fans?

My PSU is the single fan quiet model that came with my Antec sonata case, will it do?
 
No it won't from what I've seen on websites for graphics cards. They say you need a ATX v2.0 PSU for PCI-e cards as the new cards require additional power to that from the board. The motherboard will also require a 24-pin PSU rather than the existing 20-pin one.
Lastly, I would suggest getting a PSU that gives a bigger output, about 450W or 480W to accommodate all those hardware you're throwing into the new machine.

Believe the great words of MING. Believe me from experience a 380W will not be close to what it has to power. You need more than that buddy. It be a good solution for you to get the Ultra X-Connect with 500W on top of that you get a clean slate PSU and you get to connect the power that is needed and not have a jarbled mess in your case.
 
Which 380W Antec? True Power 380?

+5V -5V +12V -12V +3.3V +5V
35A* 0.5A 24A* 1.0A 28.0A* 2.0A
±3% ±5% ±3% ±5% ±3% ±5%
50mV 50mV 120mV 120mV 50mV 50mV

* +5V, +3.3V & +12V maximum output 360 Watts max.

This will handle that setup. It's beefier than most 450W power supplies.
Has individual outputs for 3.3, 5 & 12V.

I did not see an spec's for a 380W Quiet model. Check the rating label on the side to see if it matches the True Power.
 
Found it under the Sonata Case. It is a special true power 380W for the Sonata only. Check the rating label on the power supply.

PS The post to the power supply calculator above comes out to 308W for your system. That sounds kinda light to me. The 380 True POwer is as low as I'd recommend. If it's a full capacity true power.
 
Leejend, don't forget that he's looking at a NF4 system with PCI-e gfx card. Can the current PSU support the PCI-e side of it?
 
Thanks for all the advice on this issue guys.

Here's the numbers from my powersupply:

DC output: +5v +12v +3.3v -5v -12v +5sb
Max: 35A 18A 28A 0.5A 1.0A 2.0A
Min: 0.0 0.8 0.0 0.0 0.0 0.0


My current system is:
Asus A7N8X-dlx rev 2.0 mobo
AthlonXP 2500+ (oc'd 3200+)
Zalman AlCu7000 HSF
512x2 Geil pc3200 RAM
120gb Seagate Barracuda 7200.7 SATA HD
Liteon 52x CDRW
Asus 56x CDrom
ATI Radeon 9800 Pro 128mb (flashed to 9800XT)
Antec True 380S

My new system will be:
Chaintech VNF4 mobo
Athlon64 3000+
ATI Radeon x800 XL pci-e
everything else carried over
 
Check this out: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1028627&CatId=1079

But you can get the same 500 watt modular power supply (just not green) AND case for less than the power supply itself!: -
Ultra UV Wizard Black ATX Mid-Tower Case with UV Reactive Clear Side, Front USB & Firewire Ports and Ultra X-Connect 500-Watt Power Supply - $39.99 (after rebate) http://www.tigerdirect.com/applications/searchtools/item-Details.asp?EdpNo=1243199&sku=ULT31556 CASE

DC OUTPUT

+3.3V - 28A

+5V - 30A

+12V - 34A

The only probem is (maybe there's an adaptor)

Connectors

* 1x 20-Pin Main Power
* 1x 6-Pin AUX (Xeon) Power
* 1x 4-Pin 12V (P4)
* 6x 4-Pin Peripheral
* 1x Floppy
* SATA
 
You definitely need a better supply. That's not a real true power 380W.
 
Ok, well, will an Antec Truepower 430 do a good job powering my system?

The Neopower is cool and all, but a bit more than I want to spend.

I do not plan to add any other devices to my system or OC'd it so will the 430 get the job done well?

It's spec's say is +12v - 26A

I also saw the Enermax EG425P-VE SFMA 2.0 430w PSU. It is ATX12v 2.01 compliant. Would that work better? They both cost around the same.

What PSU's would you guys recommend?

I've always been an Antec guy, and just want something that will get the job done, don't need the latest and greatest.

And will I need any adapter cables to make the antec compatible?
 
I don't understand all those 3v, 5v, 12v bits... but as mentioned earlier, you need to get one which is ATX v2.0 compliant especially if you're getting NF4/PCI-e.
As far as I know, there aren't any adapter cables to make the existing psu's usable with PCI-e, but you can get a 20-pin to 24-pin adapter for NF4 boards.
 
The true power 430 should do you good.

+5V -5V +12V -12V +3.3V +5V
36A* 0.5A 26A* 1.0A 28.0A* 2.0A

* +5V, +3.3V & +12V maximum output 410 Watts max.

Plenty of capacity on the +5, +12 and +3.3 Volt outputs and those three combined can carry almost the full name rating of 430.

Also Hi EP and people. I found this place again while looking through a oooollllllldddd backup. I have filled over 10TB and was looking at my collection of antiques. Any bids on the 500Mhz Win 95 fix?
Any of the SP crew still out there?

Impressed you have kept this alive this long EP! So many sites have come and gone. :(

Just did some crude math and I apparently joined almost 18yrs ago, how is that possible???
