Will Antec TruePower 430w be able to handle this?

Reusing a 6 month old Truepower 430w (has 24amps on 12v line I think).

Rig:

Evga Free SLI Mobo
Venice 3500+
1gb Crucial DDR400
Evga 7800GT 256mb
WD raptor 36gb
Seagate 250GB seriala ATA
floppy
NEC DVD+RW


Maybe SLI when the price of the video drops to $250ish. But will teh current PSU be able to handle the task smoothly non-oced?



BTW, the evga board has 4 pin molex connector underneath the first PCI-e slot (also called e-z plug), does this need to be plugged in even though im not using SLI?
 
i think it shouldnt be too bad for that as it stands....could be pushing it a bit if its only got 1 12v rail, and its max is 24 amps.

certainly you'll want abit more power if you intend to go SLI, i dont think it would be up to the job
 
yes.

a 6800gt uses more power than the 7800gtx. dual 7800gtx is pointless no game can really handel it yet one 7800gtx is more than enough. SLI is a waste of money because when you get enough money for the 2nd card a new card is out that is better than two 7800gtx cards in SLI. another thing SLI uses alot of power considering you have to power two cards.
 
It'll work.....but for how long...............


When it gives up the ghost it WILL be expensive. More than the cost of a newer and stronger PSU.
 
yeah i can see alot of strain being put on the PSU at boot up, with that raptor drive, and the other bits all firing up at once. i know the 7800's use a little less power, but they still consume alot more than all the other parts. it would probably work initially, but i bet youd see problems later

Hardly, that PSU will handle the OP's system with power to spare.

:thumbsup:

Yup.

I always laugh at these kind of threads.
 
Laugh as you will, but a quick check of Xtremesystems.org shows nasty things that happen to those not wise enough to give some leeway on the PSU. I myself had a couple of PSU's, including 2 Truepower 430 let go on one of my NF7-S v2.0 setups. It cost me $$$.

Since switching to a stronger PSU, no issues for over a year. This is one part you shouldn't skimp on.

SPCR showed that a Pentium-D system with a 6800GT at load only drew a maximum of 223W from the PSU. What's more, the total 12V load is only a 16.9A which can be easily handed by a 430W Antec.

Some people get way too much PSU wattage for their rigs.
 
That setup shouldn't pull more than 250 watts MAX. Only a moron would rip/burn DVDs and play graphic-intensive games at the SAME time. If the PSU is in working condition, then it should deliver sufficient juice.

unless he has an X2 😛
 
That is way more than enough power.

A system with a 3800+, 2x6800GT's, 2xHDDs, 2xOpticals will only require 20A.

Since you are only runnning one VC, which uses less power than a single 6800GT, and a 3500+, not a 3800+, you could get by 20A. And since you have 24A, thats plenty. Even in SLI that 'should' be enough. But it is surely enough for a system with a single 7800gt.

RoD
 
Also, power draw peaks when first powering up... Fans and HDDs take more power to spin up than to maintain and they all hit at once. Just because it will dreaw 20A and the PSU outputs 24A doesn't mean that it'll have the juice to get it all going at once. You may have to set HDD startup delays and more.

Good link!!

The same link also showed over 91 percent load on the +12v line on the test setup. This is beyond the rating of most all Antec units, which are rated at 80 percent load at rated temperature for MTBF. This means the life expectancy of the unit will be reduced. This also means that with an OC'ed AMD system where the +12v line/lines are seriously loaded, and in combination with an nVidia graphics card, you will likely have serious issues when overclocking the rig mentioned by the OP.
 
My 3000 Venice overclocked to 3800 speed will only pull about 198 watts TOTAL (3.3+5+12V rails), and that includes the DVD burner running at full blast. A top of the line video card may add another 50 watts load. As long as the PC has adequate ventilation, the PSU should run cool and deliver at least 230 watts at the 12V rail. No one is going to run this PC at 100% load 24/7.

Even if the PSU will only last 25K hours, you're still looking at 5 years of life for an average user.
 
Good point, though I repeat....check out Xtremesystems amd count the failed PSU's. It's scary, the amount of supposed "quality PSU" that gave up the ghost with lesser systems than the one listed by the OP
 
Update: I just bought a Fortron Blue 500W PSU ($70 from ewiz, woot), it has has a combine 30amps on dual 12v lines. This psu SHOULD be able to run my rig and SLI right??

That's 91% of the power being drawn, not 91% of the PSU's total available power to the 12v rail.

...well after everyone saying the antec would run FINE, you go buy a fortron...anyways that fortron is MORE than enough.
