Q: Power supply question for an engineer

Madam / Sir, on my Lenovo SFF desktop 510s-08ISH- 90FN00BYIN I have three sata ports for 3drives. There are 2 drives pre installed. These drives get power from a cable with two sata power connectors and are connected to the motherboard with a 4 pin plug. Can this 4 pin power connector on motherboard support 3drives ??Regards John

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.

OK, I feel like a real ***** -- we've been having some issues that I think may be power supply related. I'm trying to see what I've actually got in terms of a power supply, BUT...I can't find my original documentation that would list it (that's bad, I know, I think it's just filed somewhere where I can't lay hands on it), AND I can't seem to find anything on my computer, i.e., Device manager, etc., that identifies the psu by name, wattage, etc.

I'm running XP, can't find it under Device manager or anywhere else. I don't want to take the unit apart (yet). Any help is appreciated, thanks.

I have an ancient ASUS P3V4X mobo, it's fine, and I upgraded to a higher wattage PS 2 days ago, a Sigma 550, since I have a DVD Burner, 2 HD's, Sound card, NIC, AGP video, etc. The 'old' PS was only a 250w unit, hence the upgrade.

The new one works fine, but I noticed in the BIOS I was looking at the voltages, and they are as follows:
VCore 1.71v
+3.3 3.50v
+5 4.87v
+12v 13.38/13.45v (it fluctuates)
-12v -11.59/11.67 (it fluctuates)
-5v -12.00v solid.

I don't get the -5v as showing -12.00v, it's solid, never fluctuates, and I'm not even sure what a -5v is for. ( can set it to ignore if I choose)
I do NOT use SATA drives, just your standard ATA Maxtor's, and I do NOT have a PCI-Express video card.

Any ideas on why the -5v shows a -12.00v ? Nothing is burning - yet.

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.

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;
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139031

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.

I'm building a Gaming rig for as cheap as possible.
150$ cpu - video card - 50$ mobo . I checked the Newegg power supply chart and it says I should get 450w.

I can get a 80 certified 500w PSU for 40$ or a 600w non 80-cert psu for 30$.

Newegg.com - Diablotek DA Series PSDA600 600W ATX12V v2.2 Power Supply 30$
Newegg.com - COOLMAX ZX Series ZX-500 500W ATX12V v2.2 / EPS12V v2.91 SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Power Supply 40$

If my system really only pulls 450w, would the 500w work?
more importantly, even if the 600w only runs at 75 percent, it should work also right?

I dont have 50 bucks to blow on a PSU. Hardly 40.

Hey all,
I have a PC (eMachines 2.8 P4) that would not power on at all - no fan noise, lights, no nothing. I narrowed down the problem to a faulty power supply - power supply tester showed no power output and swapped in a new power supply and now have power.

Problem now is, I have no video to the LCD monitor. Graphics is onboard. The new power supply I put in is a standard ATX power supply that does not have the ATX2 12v 4-pin connector for the P4. Without this being connected, will this cause problems overall and specifically with the no video problem?

Also, I seen a inexpensive adapter to go to ATX2 using the standard ATX power supply. Any opinion on doing this? Thanks so much in advance.

I have come to the realization that my IBM PC300PL 6565-85U's power supply can't handle two hard drives and a DVD-RW drive. It's a 140 watt. When I burn a CD, or start using the 2nd hard drive harshly if I have music playing it'll turn into a high-pitched squealing noise. Also, I get ticking noises out of two brand new Western Digital HDDs, in this machine while I didn't in my 480 watt Powermac. The ticking immediately goes away when I unplug a drive and boot with only one on.

I looked in my closet and I have a 200 Watt Astec ATX202-3525 power supply laying there that has the same layout as the one in the IBM now. I think it is still alive.

My question is basically what chance do I have of frying the board if this PSU isn't as good as I remember, and would those 60 extra watts help my case enough to justify putting it in. It came out of a Gateway GP5-166, and is a replacement for the original, so it's no more than 3 years old.

I really don't want to fry the board is the only thing, but I am getting sick of a dreadfully underpowered machine.

I just ran this: http://www.journeysystems.com/?powercalc
and I got a recommended minimum of 199 watts.

Any suggestions?
 

A:Power Supply Question

When it goes kaput, its failing circuits are capable of failing voltage regulations in all directions and can subsequently fry about anything in the system, including the board.

Frankly, I think cheap power supplies are responsible for more main board deaths than any other single cause; but, that is just my opinion.

My feeling is that you can't trust any power supply in the sub-fifty-dollar range and maybe it would be better to stick to $60 and up. It seems a lot of my main board problems started going away when I started buying Antec supplies in the $60+ range. Mine are all in the 400- to 480-watt range. I might not need quite that much wattage; but, buying lower wattages doesn't save enough to worry over. Also, the higher the wattage of a quality power supply, the less the strain and the longer the life.

So I am thinking about getting a new graphics card but i'm not sure if my power supply will be able to handle it. My computer will have:

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.

I have an old Dell 0M3918 Motherboard that has the original power supply. I'm looking to upgrade that power supply so that I can have more power, and most of the power supplies I've seen are 20 pin connectors. The board uses a 24 pin connector. Are these new PSUs compatible with my board? I can see they have a 4 pin connector that's 2x2, and my assumption is that you use that as well, but my PSU has one of those anyway and its currently plugged in at a different spot on the motherboard, well away from the main 24 pin connector.
 

A:Power supply question

All the 24-pin power supplies I've seen have a detachable four-pin part to make it compatible with the 20-pin boards. (The wiring is the same on the first 20 pins.) It usually is not visible in the product pictures; but, it is there. I have seen some detail pictures of supplies at NewEgg.com where you can see the demarkation point between the 20-pin part and the extra four pins. That's where it breaks.

As for the extra four-pin connection, that is separate entirely from the twenty-four pin part.

You can see fairly detailed pictures at NewEgg.

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.

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.

also i have another computer with only 250watt power supply, and im thinking of upgrading it, i was gonna put in the okia 420 one, but dont wanna waste it on a less powerful computer if my 3200+ xp compuer needs it instead of the 350 power supply.

my other computer has tehse specs...
amd xp 2100+
512mb ddr
cd burner
dvd drive
floppy
56k modem
60gb hard drive
thanks,

also last question - what are "brushless case fans"?

thanks

is there any way to tell how many watts your power supply is without opening the case?
 

A:power supply question..

No.

Unless it is a brand name in which case the makers specifications will have it. If you can find them.

Why not open the case to see?

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.

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.

Good day,
My power supply is making a strange noise on startup and after about 1 minute it settles, is there anything I can do about it besides replacing it?
The mother board connection is 24 pins and the power supply connection in the PC at present has a 20 pin + a 4 pin connector I do have a spare ATX power suply but it only has the 20 pin connector without the extra 4 pin connector, can I use that power supply in my PC?
Many thanks,
Brobilly
 

A:atx power supply question

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.

A:Power Supply Question

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.

My computer bought a 300w power supply. today i bought a 350W power supply but the main connector is only 20 pins. and my old power supply used a 24 pin main power suppy, it still owrks but i was wondering if this is safe.
 

A:Power Supply Question

Nope. If your motherboard has a 24pin connector, and your PSU only has 20pins, it's not a good combo. Return the PSU before your computer suffers irreversible damage, and get the proper type of PSU.

With the cost of electricity nowdays, I was wondering about power supply electrical consumption:
Does a typical power supply draw the exact amount of current it is rated at on a consistent basis or does it adjust itself to only use as much AC current as the computer is using at whatever time?
For example, say I have a computer that draws 150 watts of power for its use but it had a power supply that is rated at 450 watts. Would the electrical usage of this computer be 450watts, 150 watts or some other amount?
 

A:Power Supply Question

The power supply's energy consumption is directly related to the amount of hardware that's attached to it, therefore a 450W PS might draw a little more power than a 300W PS, but not necessarily depending on the PC's power requirements from the CPU and drives.

As per your example, I would expect the 450w supply to draw approximately just a little more than 150w.

The rating put on the supply is the max wattage drawn before the supply becomes overheated or unstable.

I purchased an Antec 550Watt True PSU on a closeout table at CompUSA, at a great price. I believe that it's brand new, and it works great. There is, however, a cracked fan - the one visible at the rear or the case (one of the 4 corners has snapped off and it won't hold a screw). Otherwise, the fan spins and the unit seems stable with 3 screws. It's too late to return, but I don't want to anyway.

Should I replace the fan? I've never opened a power supply before. Or shall I just leave well enough alone?

Hey guys,

I was wondering if this ps

http://www.newegg.com/Product/Product.aspx?Item=N82E16817171018&Tpk=cooler+master+extreme+500w

could run a 500g 7200 rpm hard drive, AMD 64 3.0 ghz 6000+ cpu, 8800 GTS 640mb, and a really old dvd rom : )
There will be absolutely no upgrading to this cpu and I would be gaming and watching movies casually.

Thanks a bunch!

PSU question:
Is my PSU adaquate for my system? I have an Antec Basiq 500w.

Gigabyte GA-MA78GM-US2H

GeForce 9400GT 512MB graphics
Kingston 8Gb DDR2 RAM PC2-6400

Samsung Spinpoint 640Gb HD
Antec TriCool 120mm fan (as 2nd fan)
Sony DVD recorder
LG Blu-Ray/HD-DVD rom, DVD-recorder (GGC-H20LK)

Computer started having power issues hours after having played a blu-ray movie in it for the first time the other day. The computer would randomly turn off, like it lost power. Sometimes I can get into the OS for a long time, sometimes it would power off as it got to the BIOS screen.

All the hardware seems to work including every fan, including the cpu fan. The computer does not seem to get any hotter than normal. CPU is not currently being overclocked. There are no BSODs.

The computer was fine before playing the blu-ray movie. The parts are no more than three months old, and only used for less than a month.

The computer is plugged into an APC battery backup which seems to work.

A:Power supply question

I think so mate it looks like a lot of hardware in there to be powering. I mean each component probably is not drawing much but you do have a lot of hard drives and fans etc etc and 8 gb of ram. I think it would not hurt to have a bit more juice to run your parts.
