Newbie AMD question.

[recon]

I have a pent 3 450 with a 200w atx psu. I am getting an amd 1.2 t bird with k785a motherboard. IS there anyway possible that this will run with this powersupply? It will only need to be tempoary as I will get a 300w atx psu next month, but I dont want to have to wait to hook up my 1.2. PLEASE HELP!!!

Welcome to the forums Recon! I'm not a power supply expert but if your planning on running stock speeds and without a bunch of extra fans and such, it might turn over w/ a 200watt PSU. Not sure!

If you check AMD's suggested power supply website here (http://www1.amd.com/athlon/power), you will see quite a few 250watt psu's listed. I really wouldn't want to use a "less than spec" psu but that's just my opinion. Good Luck, Be careful..Welcome again to the forums!

most likely not, unless you have no fans, no HD, no CD etc, then it might but a general computer won't and just hope you didn't order taht 300w PSU yet becuase that won't be enough either. It might work but you are really temering with it, I would stick with 350-400 for safty and above for power.

My friend is running a 1.2g on a 300 watt with 2 extra fans. dont know how much more he can do. I havent ordered any supply yet as I saved up for the motherboard and processor. Looks as if I will get the 1.2 and not be able to install it until I get a 400watt or so. you know how spouses can be when it comes to money. thanks for the info though.

Look down at my system (sig), which does have a 400w and a very nice case with 5 fans (only 2 included) and I put in an axail fan as well. My out to about 750USD [S&H not included]

the case alone was 130 (that came with the 400w) if you are interested. Go to KDcomputers.com--->quality store.

I'm running a 1.4 @ 1.61, 512 mb of Crucial PC2100, EPoX 8K7A, SBLive! X-Gamer 5.1, Golden Gate 40, Asus V8200 GeForce3, Floppy Drive, Toshiba 16x DVD-Rom, Two case fans, and my 5v rail drops down to 4.76 sometimes. In Mr. Graffin's words "UNACCEPTABLE!" Er. Nevermind, this has to do with a power supply and not parts per million, but 4.76 is unacceptable, and often causes system instability for me.

I have set up a 1.2 Athlon system with a HSF, 1 IBM HD, 1 Floppy drive, 1 cdrom drive, a NIC card and a KyroII video card - with a 250w PSU. It set up just fine, as long as I didn't try to run my cooling fans or sound card or overclock. Try your 200w, but with only the essentials that you will need for the next month - and if you have case fans, maybe run without them with an open case for the time being.

[Paul -The Mad Hatter]

you could also under clock.

[chaosdriven]

I would go for a 400Watt PS.
You can buy them cheap!
I got mine with an ATX case for $48.26 (35.99+12.27SH)!!!!!

The case is reasonably nice, especially the top mounted PS which allows me to have installed the cooling duct from the side panel.

[train22]

carefull, qulaity is important, I don't know how long this PS will last.

He's a good friend of mine and I was telling him that I was REALLY unsure of running the 200w ps on that chip. He just needs to get by until the beginning of Oct and he will have the extra money to buy a PSU. He does plan on getting a 400w PSU. I WAS toying with the idea (i know it'd look crappy) of using an AT power supply to run the HD (x2), cdrom, and floppy to help unburden the load. I THINK that might get him through pretty good until the 1st. Any opinions?

[Fanman]

That might just do it, but there's only one way to find out. Make sure everything that you possibly can is running on the old AT unit.

[SickBoy]

Yeah I'd say run the drives, fans and such off the AT PSU and leave the full 200W to the mobo, cards and CPU... You'll probably get by, but you definitely need to convey the point to your friend that he needs a 300+ W PSU ASAP....

Yea I wasnt thinking when we ordered the cpu/mb. I know where he can get a 300w ps for $20 but he had to fight tooth and nail to get the cpu/mb. So he just needs to get by until he gets paid (monthly) on the 1st. After discussing it with his everlasting loved one, he cant get it till then and she actually agreed to a 400w ps.

[ve6jhc]

I have seen a 1.4 T bird work OK on a cheapie Azza MB with a 235 watt PSU. The system was very basic....no case fans, one HD and one CD etc.

[WooK]

I`m running a TB1400 on a 235watt psu too with all the parts mentioned in my sig. I didn`t even know i had to get a 350+psu for my system. :/

I was just wondering, what is the baddest thing that can happen with my psu/system if i continue with these specs?

[Rob Cork]

I hear a lot of people saying that even 300W won't cut it anymore, but based on my own experiences I have to disagree. I'm running with a generic 300W and no real problems - stability is fine, though sometimes my +5V line drops down to 4.88...

I have one hdd, two CD-ROMS, two 120mm case fans, two 80mm case fans, a GF DDR and a tbird running at 1600 and 1.85V. I admit it looks as though my psu is beginning to strain on the 5V line, but at 1533 and 1.75V my 5V line is at a healthy 4.98V. I reckon 300W is fine for moderate overclocking up to about 1400 or 1500MHz - I think it's only after that, and when you start running more than 1.9V through the cpu, that you need more wattage. I'm gonna stick with this until it really becomes a problem, even a 350W enermax psu still costs over £50 :(

Just my 0.02...

[xanthan]

Hiya, i am running using a 235W PS with a duel fan hsf, 4 case fans, cdr, 2 nic, 2 hd, and a modem. no problems so far.

[ve6jhc]

A lot of little problems can be traced to a weak/undersized PSU. I have seen system that lock up or freeze at random stop doing that with a better PSU.
