Should not be a issue. Drives these days do not use a lot of power. Only real concerns for power supplies these days is graphic cards and CPU's. If you Google PSU calculator you should be able to enter in all your information and get a correct answer.

I have a W540, which currently uses a 170W power supply (20V 8.5A) I also just recieved a docking station for a P50 which has a 230W power supply showing 20V 11.5A. The connectors look the same, but I'm hesitant to try the 230W power supply in the W540. Should this be ok to use the 230W power supply with the W540?













Solved!

Go to Solution.

A:Power Supply Question - Can I use the 230W power supply with a W540?

230 watts is the maximum power supply, it only supplies the power needed by the computer. I sold my W540, so i can't test this for you. But i do the use the ThinkPad X1 Carbon with the 230 watts power adapter without any problem.

I have a server that I would like to upgrade to 20 1TB Hitachi HD's. They claim max startup current of 2A. and idling down in the .5A range. The platform will be a 775-series X48 with a 6600 Core Duo. Graphics card is small, does not even require aux power connector. Not needed to just supply the KVM with 1280x1024. No other signficiant sources of 12V drain exist other than the MB/CPU, a slim CD-Drive for installs, a slim floppy, and one additional 30GB SSD startup drive (2W when active).

I am looking at an 850W Corsair. I've heard these are quality supplies and I don't want multiple rails since no one really knows what sort of Voodoo goes on as to how they divide multiple rails up. And I don't want to get into that. I will be using a single-rail +12V PS. I can add a second if I need to but I'd rather not.

Do you think this will be sufficient for handling 20 Hitachi hard drives? "Green" drives are a non-starter since they will drive my Raid 6 controller, and then me, off the deep end with TLER issues. I do have staggered spin-up control of the drives with the controller.

Thanks for any help.
 

A:Power Supply Question & HD Power Consumption

Power Supply Question & HD Power Consumption, Pt. 2 - Laptop vs. 3.5"

My second question is this - I have a BTV server that needs to be on at all times during the season to record shows during day and evening.

Suffice it to say that you CANNOT reliably put one of the critters into sleep/hibernate mode and expect it to wake up and reliably record a show. It just won't happen.

Now, this is one case where I can use "Green" 3.5" drives, but I am also considering banking 500GB 7200RPM or even 5400RPM laptop drives. These will all be on a raid controller, but since they will be in pass-thru mode or RAID 0 mode the controller won't freak over TLER like it would with RAID 5/6 and mark the drives bad. The controller also has more than adequate cache to handle a 5400RPM spindle as OTA HDTV generates little more than 2.5MB per second per channel. Even 4 channels at once is 10MB/s and that should not tap the ability of a 3Ware controller with cache on 5400 RPM RAID 0 or even pass-thru drives.

My question is this - 2 500GB laptop drives burn much less startup and idle current than a single 1TB 3.5" drive. Has anyone tried running multiple laptop drives on a RAID controller, and what sort of luck have you had? What sort of sustained throuput can you obtain?

Electricity is a huge factor here, at 12 cents per KWh. I can recover the marginal cost of 2 500GB laptop drives vs. 1 1TB 3.5 drive.

Does anyone here know if the talk I've been hearing about GF4 Ti's needing a minimum of 300 watt's with the power supply is fact or if it is some peoples idea of problems with compatability on certain systems? I went to the Dell and Gateway websites and they offer the 4600 in their systems that are powered by 250 watt supplys. I was hoping to find some facts on this. Also no reviews ever mentioned it.
 

A:GF4 Ti & Power Supply question

Everyone gets pretty confused about this. No, the card in itself does not require 300w, but will draw apx. 50w & up to 75w under load (extreme gaming) However, adding another 50w draw may tax your system, necessitating a 300w psu, or better.

So i was reading a review on a chassis/case i recently bought...and they said that the psu sucks (i kno, most power supplys that come with case's usually arnt top notch) but then he went into the +12V being a 15.0A..now ive always known about these numbers but never knew WHAT it meant..anyone want to explain? lol
 

A:Power Supply Question

A=amperage, power(watts)=volts x amps(current)

The 12 volt rail(s) run the video card, CPU, drives, and fans. Often the video card specs say about the amps on the 12 volt rail you need. It's much better to look at the rail specs of a PSU because some PSUs will have most of the power on the 5 volt rail and be rated high power like 400-500 watts. For a basic system 18a on the 12 volt rail should do, but for a gaming system with a single high end video card you want about 30 amps. With dual video cards you need to spend some dollars!

Recently my power supply got damaged due to a thunderstorm even tough I had a
good surge protector installed.

Obviously the best protection would be to disconnect the computer from the plug.

But I wonder if just switching the surge protector off would provide the same security ?
Or could a lightning still cause damages ?

Although highly unlikely, it's still possible that a really bad direct strike would still find it's way down the path in to your PC.

As long is there is an unbroken chain of wire from the house electric system to your PC, there is a chance (albeit an extremely small one) that you could still suffer some damage.

IMO - is this likely to ever happen? No. Don't worry about it.

Hello,

Trying to diagnose a computer problem.

The computer does not boot up. It starts, and all fans are spinning, and the HD ( I tried 2 hard drives actually) seems to be spinning.

I am wondering if the PS is failing?

If the PS is done, will you get ANY power at all, or will you press the on button, and get no juice?

Also, there is no burning or "heat" smell coming from the PS.

If it is not the PS, my next guess is the MOBO, but I am not really sure how to test if a MOBO is pooched.

Thanks in advance.

Hello everyone ...

Although I am a huge PC enthusiast, I am building a different sort of machine that makes use of a typical PC Power Supply.

OK, I'll just admit it ... I'm making a food dehydrator ... and I need to rig some fans to facilitate airflow / convection.

Here's my idea: Use a powersupply, connected to several PC fans, to drive that airflow through the dehydrator itself.

My question: The main 20 pins connector (coming from the Power Supply) needs to have a jumper on some pins .... right? Which ones? How do I rig this puppy so it's stand-alone and powers the fans only?

Thanks!
 

A:Power Supply question

They are all posted on good power supply manufacturer sites... and in such books as Building and Repairing PC's.

The problem is that food properly handled in a dehydrator requires better, and more consistent airflow, and temperature controls, than any power supply I have seen can handle... leading to spoilage. You are likely to have quality control problems... no to mention insects.

I think I found a question in there somewhere......

You want to know if you can use a standard ATX power supply in your case? First we need to know what case you have. If you don't know, then you could also take a look at the PSU you have in there now and see what size it is. It will tell you on the sticker attached to it.

I'm wondering if perhaps my random reboots are power related. I've bought a new PSU (cheapy I'm afraid) to no avail. I've read in other forums that it's really a key to have the +12v rail over 20 amps for Athlon XP systems (even though AMD recommends only 15-18 amps) which my new power supply isn't (old psu wasn't either). Any suggetions on the what amps are needed on the different rails for best, most stable results? Any help would be great. Here are my system specs (no overclocking):

Operating System : Windows XP Professional

I have a powermax power supply that I bought like a year ago at a local computer store. Ive been having an issue with it. It seems that sometimes it wont power my computer, it seems to power up and quickly shut off. If I change the voltage setting it works fine but my pc doesnt boot up it just powers on. The way Ive been getting it to work is that when it doesnt power on and stay on I hit the on off swith on the power supply itself. I put it to on and i push my power button on the front of my pc then it starts and stays on. Sometimes it doesnt work like that but rather after I toggle on and off the power switch on the power supply several times. I have no real idea what it could be. has anyone ever had something like this happen?

BTW I took the power supply to get it tested and it works obviosly.

I dont know if its my power supply or maybe a motherboard issue or what?

Please help
 

A:Power supply question

First of all STOP cycling the power on and off. You will make a bad situation much worse. Next replace the ps. Cold boot problems that go away after the first failed boot are almost always ps problems. Do not buy a cheap ps like powmax, deer, allied, foxconn, raidmax or any other cheap brand. Go with a quality unit like antec, enermax, coolmax, enlight, or sparkle. There are other good brands, however those are what I use in my builds.

I just got a new 500 watt power supply. The old one was overheating. The new one has a switch for a normal fan or turbo fan. The temperature runs around 48 C most of the time but has spikes up to 70 C (I have a temperature monitor software). When I put it on Turbo the system stays nice and cool all of the time. Is it going to hurt anything to leave it on Turbo all of the time? Thanks,

A:Power Supply Question

It will hurt nothing but your power bill (how ironic), and your ego if you are competing with someone for the quietest machine.

Of course, it may decrease the time before the fan bearings wear out, but I don't think that's a big concern at all.

I am looking at new power supplies and was wondering if it pays to buy one larger than you need at this time?

Does a 550 watt power supply draw 550 watts all the time or only when needed? If they do not draw to their maximum capacity, it seems like it would be better to buy one larger than you need right now because the only cost would be the drive itself and not an increased electric bill and more heat.

That depends on what else is going to be in the system. If you are putting in a mid range graphic card then you will want a 400 watt psu. If not, then 350 would be fine. Also, its not only the watts that are important, but the amps on the 12 volt line that are important too.

1st of all define "strange noise". You need to post the EXACT make and model of the problematic power supply and the EXACT make and model of the spare power supply you have that you intend to use.

If your machine has a PCIe graphics card installed you cannot use the power supply with the 20 pin main connector. The +4 pin connector on the power supply with the 20+4 (pins 11, 12, 23 and 24) supply 75 watts of power to the PCIe bus.

I'm going to be purchasing a new HDD and some extra RAM.

I currently have a PSU with a MAX Output Power of 550w. I just want to make sure that adding these components won't effect my PSU output power since I don't plan on buying a new one anytime soon.

Also is there a way to see how much power your PSU is currently using? There doesn't seem to be any info on it in CPU-Z.

Thanks for the replies.

RAM and an HDD will add very little to your power consumption. An HDD typically uses under 10 watts when spinning; less than 5 at rest.

You can measure the power consumption of your PC with a Killawatt device--available online from many vendors for maybe $20. You plug the Killawatt into the wall socket and then plug your stuff into it. It will measure the actual wattage draw of any appliance---radios, TV, lights, whatever, as long as it takes 110 volts.

Take a look at my specs and look at the measured power consumption in the "other info" section. I used a Killawatt to get those numbers.

I'm building a new computer and am wondering about power needs. How can you determine what wattage power supply is needed? What is it dependent on? Any help would be great. Thanks.

I did a check to see how much power my computer needed and apparently it needs 38w. Is this right? It has a max output of 230volts and i am looking to get a new video card, i know i will need a new psu you to sufficiently power it, i might get a 400. Would this be enough? Thanks
 

A:Power Supply Question, 38w?

Where di you see the 36w at?
For a typical desktop, you're probably looking around 300-400w, but then again, if you tell us the computer specs, you could get an answer with better accuracy

Ok, I just bought a DFI Lanparty mobo for my AMD 64 3000+.

Anyways, I set up everything and turned it on and it worked fine till I started to install drivers. After installing the drivers, I rebooted and my Power Supply started making a funny smell, and my UV case lights wouldn't work anymore, yet everything else still seems fine. My UV cases lights were actually plugged into the same power cord as my Video Card and HDD and they still seem to work fine. Could the smell just be the UV case lights burning out? Could it be my Power Supply? I'm confused.

Alright I'm a little frustrated right now but it might actually be a good thing. I was planning to buy an ULTRA X3 800w power supply from TigerDirect.com but when I looked today it was listed as unavailable, just my luck. The unit was listed at $199.xx and came to about $215 with shipping.

Anyways, I've been searching around and there are few retailers that sell this unit; it's been unavailable from ULTRA's online store. However, while I was browsing more listings I came across a sweet deal for the X3 1000w model, only $205. This model is listed on Tiger for $299 plus shipping. So, I just bought the unit because it was almost what I would have paid for the 800w on Tiger, came to $222 with shipping.

My question is, 1000w is probably way overkill for my system, would a PSU this powerful (70A on a single 12v rail) damage my system's components if I were to use it anyway? I think I need a minimum of 700w for this system - Intel q6600, two 8600GT's in SLi, three hard disk drives and two DVD drives. Not a very power-hungry setup so I am a bit worried about using this PSU. Any input on this would be greatly appreciated.

Wait for a second/third opinion, but I believe it would NOT, as the system would only draw the power needed from the PSU.

I have a Antec PP-303XP power supply and my problem is this. When plugged into a system board I can power it on just fine but, when I try to jumper the 14 and any black connection the power supply does nothing. I am trying to use this to test some other equipment that I have and I don't want to have to keep turning the system board off and on and mess something up. Any help would be appreciated.

Standard protection circuits for a commercial home user machine. You need a better power supply that is engineered to handle such things.

I would like to know what Graphics card and power supply is compatible with an Acer Aspire M3450? I have bought a EVGA Geforce GTX 650 graphics card, but I know I need to upgrade the power supply also, and I need to know would be the best inexpensive power supply that I could install for it? The graphics card says it has to have a minumum of 20 amps on the +12 volt rail. I would appreciate any suggestions. Thanks
 

A:Power Supply Question

I cannot find any real specs on that system. I assume you have checked and you do in fact have a pci-e slot on the mb.

I would think you are installing this card for gaming. Gaming and cheap/inexpensive are mutually exclusive terms. If you are going to game with this system, you need a quality pw supply. Here is an example of what you need;

You do need to understand that acer uses low end ie junk parts in their systems and even with a gtx650, you might not be satisfied with the performance of the system.
