M91p SFF external power supply upgrade

Q: M91p SFF external power supply upgrade

Hi. I just purchased a Lenovo Thinkcentre M91p (machine type 0266) which has an external 150w power supply. I purchased it to be used as a HTPC and i want to put a gpu and more ram in it. The problem is the power supply, all the ones i see people talk about have an internal 240w power supply. On the back of the pc is a DC in jack thats directly into the motherboard itself. I ran some calculations on power usage and the site i used said the recommended power supply size for the standard unit is 150w with a peak load of 123w. Adding the gpu alone pushes the peak load to 140w (nvidia gt730) with a recommended supply of 180w. My question basically is how can i upgrade an external power supply when all i can find is standard 150w external replacements or internal ones that wont be of any use

A:M91p USFF: uprate external power supply for graphics upgrade (GPU)

Update: im guessing i could just use any power adapter for other pc's or laptops with 180w or more, it just needs to have the correct ending which is a 6.0x3.0mm connector. I could even possibly use an adapter to make the correct ending. i dont see why this wouldnt work as the power supply is all external

Hi,I recently got my hands on a M91p SFF with:i5-2400 CPU8gb Ram250gb hdd @7200rpm2 tb hdd @5400rpmand 240w PSU What I want to do is to convert this machine into a [email protected] / 1080p gaming machine. My plan is to buy the MSI 1050ti lp and even though it seems to run on the 240w PSU I feel that I want to upgrade it to at least 300w to be safe and so that I can upgrade the ram to 16gb and maybe add an extra fan and a usb hub in the front, where the optical drive used to be, so that I can connect more than just two USB gamepads in the front.After some goggling I found this power supply: http://www.bequiet.com/en/powersupply/496 According to my measurements, is should fit. But I want to be sure, will this work in the case?Also, I think I read somewhere that Lenovo does not a use standard ATX connection, but from what I can see, this system uses a standard 24 pin ATX connection to the motherboard. I might be wrong though. I am no expert on computers and I have never upgraded or built a system before so I ask here to be 100% before I buy anything.  I hope someone where can shed some light on my situation. Thanks

Ok, I just bought this power supply. It doesn't fit into my case. So here's what I'm thinking: I put it in a place where it wouldn't be bothered, touched, anything like that, and just set it outside of the case on a platform. It's an Antec SmartPower 430W. What do you guys think?

First of all thank you for viewing this topic as the data on this hard drive is extremely sentimental.

Some of my greatest memories (such as my wedding), are on this hard drive, so I appreciate ANY help you can give me.

I have a 1.5 TB Seagate Expansion External Drive ST315005EXA101-RK, yesterday my foot decided to accidentally kick the power supply and a noticed a few minutes later windows was giving me the following error message:

"Windows was unable to save all the data for the file F:\$MFT. The data has been lost. This error may be caused by a failure of your computer hardware or network connection."

At first I didn't think much of it. I viewed the drive and all the contents were shown but no videos were playing. I thought it was a codec issue at first because I just recently nuked my computer. Most files don't open on the drive. The thumbnails for the pictures were still showing, some pictures I could still open, some text files were intact. Later on I made a small text file, wrote something in it, and saved it to the drive to see if I could still write, and it saved properly. I have never restarted my computer as I've read it may not allow me to see the drive anymore. I tried copying the files but windows gives me the "Cannot read from source file or disk." error. After a little while I opened up some pictures (possibly not the same ones) and only 20% of the picture I opened would be showing, the rest greyed out. After I we... Read more

Hi, I am new to these forums. Was hoping to get some advice on using another power supply for a new vid card that i got. The vid card recommends that I have a 350 watt power supply, but mine is only 200. I do have another power supply from an older computer just laying around, but that is also only 200. Is there a way to use that also? Even if it does sit on the outside of my cpu it doesnt matter. I dont have a really fast comp, old P3 400, so my budget is very tight. (thus reusing existing parts) Any help is appreciated. THX

A:external power supply for v-card

What Video Card are you talking about? It may be a bit much for that system, you might want to get something a little more matched to the system.

There is a way to do this but it is a little different than you are talking about. The best way would be to use the other PSU to power things like Drives and fans. Those devices can use the connectors already on the PSU. This may work if you can divert enough power to the second PSU so there is enough power left for the other devices and the Video card.

This could be very easy to do, or it could be very difficult. According to your level of electronics experience as well as the particular PSUs you have. Some PSUs will only power on if the mobo connector is attached(which can be circumvented)

You'll also need a way to turn both PSUs on at the same time which is not too difficult either.

I have looked around and around. I'm completely stumped.

I have a Lite-On external dvd combo burner. On the rear of the drive is the power connection, usb2.0 and l/r audio rca out jacks (red/white). Above where you connect the power cord is also a toggle on/off switch. During a move, this toggle snapped off. In the off position. I got to the card and the toggle switch is soldered to the card. No way to get in there (easily at least).

I haven't been able to find a replacement card and I'm reluctant to jam a paperclip (or whatever) in there wiggling it around and scratching up the card.

Any suggestions?

I have a 3.5" external hard drive that requires a (round) 5-pin power supply adapter. I lost the original, and bought a new one from an electronics manufacturer. The plug fits the slot, but I am not getting power to the drive and no signal is reaching the PC.

Without buying another power supply (the one I bought was hard to find - I had to go online and find a parts supplier, and I don't want to return it until I know what the problem is), how do I check to confirm whether the external drive is working, or that the external power supply and the drive are properly connected?

A:checking external hard drive power supply

IMO it would be much easier to just buy another enclosure and pull your drive out of the one you are using now. Install it in the new enclosure; good to go.

I have a Gateway GT 5082 ( Athlon 64 X2 , 2ghz flavor) I believe I have 2 problems if I want to purchase a decent video card. The stock power supply i believe is only 300W. Probably need around 400W to power a good video Card.

It comes with a PCI Express slot but even if I had the recommended power supply I really dont see an empty slot on the motherboard to put in the power connection from a new video card ( such as the nVidia 7950 GT ).

Do they sell external power supplies that I could run indepently of my computer and just power a video card? It would seem like a pain in the *** to replace the oem power supply so let me know what you think!

Yes I know there is an inherently 3rd problem the fact that I purchased a gateway haha... but just looking for some solutions here.

The external HDD is Seagate Barracuda-160 GB IDE.

Off late Ive been getting errors stating that there is a power surge on USB when I connect the external IDE HDD and all the USB slots are dead until the PC is restarted inspite of my HDD having an external power source.Why does this happen?

When I disable 2.0 in BIOS there is no such problem.But the USB connection is very slow.What could be the cause of the problem.What is the solution?

A:External IDE drive with power supply connected via USB 2.0 freezes PC .why?

If the External is faulty you could wind up with probs with the system itself. I would stop trying to force something into a system that may well have a current problem and see if I couldn't test it after I purchased a new usb wire for the thing at the very least.
Your External could very well be bad. Jazz

First of all I am sorry of this has been answered somewhere, but I haven't been able to find it and I really need a solution.

My desktop does not detect and external hard drive that do not come with their own power supply. I have many externals that also plug into the wall and they are working fine; but whenever it is an external without a plug, i.e. the portable ones they are never found.

They do not show up in Computer Management, so it is not because I did not assign a letter to the drive.

I have tried various things, but I don't know what I should be testing for or looking for.
These externals all work on other laptops and other desktops perfectly fine so it is not the externals. When they are plugged into my desktop, they light up normally like they should, but the desktop never detects them. I have tried these externals with the different USB cable I have on hand, but nothing seems to work. It doesn't matter which USB port I plug the device in, it still gives me no response.

I am running a i7 860 on a ASUS P7P55D Pro.
If anyone has any information or a ideas please let me know.


A:External Hard Drives without their own Power Supply are not detected.

This is a rather common, but sporadic, problem. The issue, I believe, is that the USB ports on the problem PC are not putting out the specified power to run the drive. This is a problem typically seen in laptops.

IIRC, USB 2.0 specifications require the supply of 2.5 watts of power over a maximum of 5 meters at 5 volts (0.5 Amps). If you are ambitious you could test for the correct specs with a good multimeter.

The other possibility is that the problem external drive is requiring more power than is supplied by the USB specifications. This is not likely in your case because the drive works on other PCs.

One work-around, in either case, would be to used a powered USB port for that PC.

What do you have now?
Think of your psu as the heart of your system. If you lose the psu, it can potentially take out everything. So obviously you don't want to skimp on it.

With a quality brand, it doesn't matter if its multi or single rail anymore, and your systems new enough any modern psu will be compatible.

Your current setup, with 5770, could easily run on 450ish W, so a 650W isn't too overkill, and allows for future upgrades.

I'd recommend a 650tx from Corsair... But they are pricey.
Newegg.com - CORSAIR CMPSU-650TX 650W ATX12V &#47; EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply $89.99<-- Very good price, usually over $100
Newegg.com - Thermaltake TR2 TRX-650M 650W ATX 12V v2.3 &#47; EPS 12V v2.91 Modular Active PFC Power Supply $55 bucks after mail ins.

But basically paying over $75 before sales will give you a good psu.

Also remember, a quality psu can last multiple changes to your system

The computer only comes with a 460w power supply, with no option to upgrade. Is this a problem? For a quad core, 1gb video card, and 6-8gb of ram, I would imagine he would want a bigger one, at least to be safe. What do you guys think?

If this is a custom build, then there should be no issues with upgrading the power supply.
It may run ok with 460W, but if it were me i'd get something better. probably 650w or better.

I am replacing the existing graphics card in this machine with a gForce 1070. I need at least a 400W power supply though. I purchased a Corsair 750W power supply, but this doesn't seem to work because the cable that connects to the mother board, i think for the CPU, is a 4 wire connector, and the new power supply has a minimum of 6 What is a beefier power supply that i *CAN* install in this machine to adequately power this card? Thankyou

A:Need to upgrade my power supply

From what I read elsewhere, you should still be able to use the power supply in question.  I personally did not try it, but others claim that you can use the pins on the 8pin connector that match up and let the others hang outdside the connector.  Some say, depending on the exact model of the Corsair PS, that the 8pin connect might be able to split.  Meant to split, not cut.

I recently bought a HP 7760n, model # RK570AA and I want to upgrade the power supply in the system to atleast a 550w ATX form factor unit with a power connection for PCI express graphics. I have seached the net and can't seem to find anything. I called the manufacturer and of course they will not give me any recomendations except using one of there units which a 450w is the highest they all offer and the price is through the roof as well.
Any suggestions on what would work with my system?

I took it back and got another one same thing happens. What Dell just takes Dell Power supply's. Dells didn't have a off and on switch on the power supply This one does. Would that make a difference? The switch isn't in the open it behind the sheet metel. there no opening for the switch.

I am trying to find a more powerful psu for my HP Pavilion 7955. THe original psu is only 200w and it loads down . I have added a second HDD , a nVidia 256mb video card and a seconf DVD writer/player. It is obvious that the psu is under powered because I can here it labor under laod and the video card response to adjustments is very slow. The psu is a certain physical spec and I am having a hard time finding anything that will fit into the case. Any suggestions?
I was considering running two 200w psu's but would rather have a 350 or 400 w psu instead.

No it won't hurt the motherboard. The only thing you need to watch for is that a standard ATX power supply will fit in that HP case.

A:Power supply upgrade

JMC_1988, welcome to the forum. Yes, the power supply unit (PSU) is a standard ATX.  I like Corsair products.  They make PSU's that will give you clean, stable power for the system.  Modular PSU's are good for mid-size cases.  They allow you to only use the cables that are necessary to run the computer. Please click the Thumbs up + button if I have helped you and click Accept as Solution if your problem is solved.

I have a Dell 5150 (purchased in 2005, so four years old) and the fan of my power supply is dead. My computer is running fine but obviously it is not safe to keep going without a fan. It came with a 305W power supply, very low-end as expected. I am therefore in the market for a new power supply but have heard some conflicting advice.

I did some research online and read from one source that it is perfectly safe to add, say, a 550W power supply even if you only started with 305W. The source stated that a power supply only uses what it needs to use, so putting in a higher wattage will not harm your computer, fry your motherboard, or overwork any devices. When I called Dell, who is not well-known for perfectly sound tech advice, I realize... they told me to order the exact same power supply the computer came with because that is what the computer was created to run with and that it would "fry my motherboard" if I tried to put a higher wattage power supply in there.

I also have a new video card, a NVIDIA GeForce 8600 GT. It requires a minimum 350W power supply, which Dell now says I will not have because it's 'dangerous.'

Who is correct? Is it safe to upgrade your power supply in an older computer? Why or why not? I'd like a yes or no but also a bit of an explanation if anyone is willing.

Hopefully someone here can help clear things up for me. Thanks in advance.

A:Can I upgrade my power supply?

What Dell told you is not correct. You can use a higher wattage power supply, and it will only use the power that it needs. A replacement power supply needs to be of good quality, needs to physically fit into the Dell case, and the power pinout for the 24 pin connector needs to match the motherboard (Dell used to use a non-standard pinout but stopped the practice a few years ago).

I still have an old PR03X docking Station, will this work with the Precision 7520?
What about the new Thunderbolt Docks - I read somewhere that I would still need  to plug in an additional power supply for the Precision models since they use so much power (180W) even when they are connected to the Dock??
If that is true, can't I simply buy some generic USB-C Docking Station, i.e. what does the Precision Laptop do in regards to power supply from USB when I have already the regular power supply plugged in? Hopefully nothing in regard to charging from USB-C? Or how does that work?

I remember reading somewhere that the acer tc-605 didn't allow a power supply replacement because it lacked a certain cable or something like that.
