90 watt vs 65 watt power supply

I have a T61p. It came with a 90 watt power supply. I ordered an extra power supply when I ordered the system and was sent a 65 watt supply.
Is it OK to use the 65 watt on my laptop?
Does it simply re-charge the battery slower?

All systems with a dedicated graphics card require a 90W power supply for proper function. A 65W PS will simply not offer enough power for a system with dedicated graphics card to function at full potential - note this refers to a situation when the computer is in use - which may eventually cause issues with the computer. While shutdown, the lower watt rated PS will charge your system, albeit more slowly indeed.
Hope that helps

Can i use HP 90 watt power supply in place of my 120 watt?

I have an HP Elitebook 6930p, that uses a 120 watt power supply. It's output is 18.5 volts and 6.5 Amps.
I have another power supply that I want to use when I take my laptop home. It is from a different HP laptop computer and is only a 90 watt power supply. It's output is 19 volts and 4.74 Amps. Can I use this power supply to run my laptop? Thank you for your help. Al

600 watt power supply questions and video card upgrade questions

I am looking to upgrade to a Xfx Radeon 7970 Double D graphics card but i was wondering if the HP 600w psu that came with my Hp Envy Phoenix H9-1350 has a 8 pin and 6 pin Pci-e connector because that is what the Radeon 7970 needs. Also I am wondering if it will fit into the Hp Envy Phoenix H9-1350 because the case seems small but the card is only 9.3" long. I currently have an Amd Radeon 7670 but I think it is time for an upgrade but I am just not sure if the power supply has the correct power connections needed for the Radeon 7970.
This is the card I am looking to get:

This is the computer I have:
http://www.bestbuy.com/site/HP+-+ENVY+Phoenix+Desktop+-+12GB+Memory+-+2TB+Hard+Drive/6890832.p?id=12...

I understand you want to know if the power supply will have the necessary connectors for the desired video card.
According to the specifications, it lists the case as a mini-tower which is on the small side. You may need to use a tape measure to find out exactly how much room the system has in regards to length. It has become much better, but other components (such as the HDD) were at the end of the PCIe slot limiting the length of a video card. Sorry I couldn't provide anything more specific. The manuals are somewhat vague as far as the internal dimensions and I don't have access to one to verify the dimensions.
Ordinarily, I can find more information regarding the power supply not that seems not to be the case here. According to this thread, the PSU has two 6 pin PCIe connectors. You would need something like this to convert one of the 6pin connectors to 8pin. As long as the PSU is capable of pushing enough watts, it shouldn't be an issue. The card needs up to a 500W power supply, so the 600W power supply should be just enough to cover it.

65 Watt Power Supply

Can anyone give tell me how I can find a new (but dependable) power supply for my 12" G4. I've been told not to purchase an off market brand as it may damage my system and/or are not reliable. I've looked on the store site and searched but they don't seem to be available.
Any help appreciated.

If you search the online store for "ibook power adapter" you should get some hits.

How much can a 430 watt power supply take?

Hello,
I am hoping someone can help me out. See below for my rig. Do I have too many components for my Antec 430 watt True power? I haven't been able to find any accurate power ratings for these components.
Any help is greatly appreciated.
Thanks,
CD151

I agree you should be fine, and that the site overestimates a bit (it says my setup should have at least 386 watts, and I've been fine on my 380W PSU for over a year now of near 24/7 operation...even though I believe that the PSU's max possible output across all rails is only 330W total). The bottom line is that any modern PSU from a decent manufacturer (and Antec is a pretty good choice for PSU's) will do just fine.
Note that the PSU calculator site uses the *max* possible power consumption for all the components (i.e. the Athlon64 CPU *does not* draw 89W of power all the time, or even all the time when it is at 100% utilization), and the same applies for the other components as well. A little while ago I purchased a power monitor thingy that plugs into the wall socket and has a readout that displays the current power draw, as I was fed up with people always thinking that my PSU was woefully inadequate for my setup. At idle, my system, with all its drives and PCI cards and overclocks, pulls a grand total of 150W of power. At 100% CPU utilization (Prime95 torture test), it pulls a little under 190W. At full CPU and GPU utilization (playing HL2, and the rthdribl demo), the total power drain is always under 225W. Now let's bear in mind that this is power drain from the outlet, *not* power applied to the board. Because the PSU is, at best, 85% efficient, 15% of this energy (at least) is lost as heat in the PSU, meaning that only about 192W is actually going out to the board at full CPU/GPU load, and since the PSU is capable of sending up to 330W out to the board (assuming it performs up to spec, which it should given Antec's reputation), I have quite a bit of headroom even on my "small" 380W PSU, even though I'm running more hardware than most users.
So anyways, the moral of the story is just get a quality PSU from a manufacturer that is reputable for making good PSU's, and you shouldn't have to worry about a thing.

Shock Therapy - An Athlon64 / FX Power Supply Guide

I used to make a hardware list of all the components I would like to incorporate in my next
computer build. Normally...at the bottom of that list would be the power supply, not that I
didn't think it was important, it's just that my other hardware was so interesting! Today, power supplys
seem to take a back seat to blazing-speed CPU's, Dual-Cored processors, glitz and glamour
video cards...not to mention supersonic, heat-sinked RAM and modular, gizmoe'd PSU's promising not
only over-achiever specifications, but eye-candy as well. The lowly PSU....tucked up somewhere inside
it's dark and lonely loft....effortlessly supplying us with the energy required for important 3D imaging
or just funning with the latest games.
What a power supply does is rather simple. It converts your office or home's socketed electricity to
usable 3.3v, 5.0v and 12.0v energy...that's all. A power supply that cannot efficiently do this will-
over time-cause computer crashes, continuous reboots and shutdowns, and worse...expensive component damage.
And now, with faster processors such as AMD's Athlon64 and FX line of CPU's, never has there been a time, when
choosing the right power supply is so important! This article is written for those using these high-powered CPU's!
Well...Do we have your attention!?
If you are experiencing these problems, or still scratching your head over that last RMA....could be
your PSU is trying to tell you something.
To begin with, a power supply's ratings refer to its maximum output under ideal conditions. No power
supply is 100% efficient. In high-quantity manufacturing, power supplys may not put out any more than 60% of
their advertised specifications. In any PSU, that rating can be further reduced by the effects of heat
and electro-magnetic radiation. That's where "switching" power supplys come in. A switching power supply draws
only as much current that is needed from the AC input. Buying a hefty PSU with this feature will guarantee
that you will be paying no more for electric service, than you would with a cheaper, less powerful unit.
One of the most common causes of power supply inefficiency, and ultimately failure is dirt. Dust and
foreign materials can cause the beginning of the end for a power supply, by attacking the fan first.
It begins by slowing the fan down...thus creating heat through friction, then ultimately burning it out.
PSU's with high-quality ball bearing fans are a must. They are far more durable, and not as likely to
become noisier as time goes by.
As a general rule...a failing PSU will usually emit abnormal sounds, followed by unstable voltage readings....
then the computer crashes or lock-ups, with random shutdowns, and sometimes...refusal to even power-up.
If you think your power supply is on its last leg...better to deal with it now, or face the more serious dilemmas later on.
APM (Advanced Power Management)
APM is a feature originally developed by partners, Microsoft and Intel. It relates to a systems ability
to utilize different states in regards to a systems utilization of power. On, Off, Standby and Suspend
are examples...these are BIOS features, not PSU functions. APM only requires of the power supply, the
function to turn power on or off through an electrical signal, and the presence of stand-by voltage.
All ATX power supplys are required to incorporate this feature. However, if some components in a computer
are not APM-compliant, your system may encounter errors or freezes when going into hibernate or stand-by
modes.
ACPI (Advanced Control Power Interface)
It's the latest power management control that was developed by a conglomeration of IT corporations. This interface
is O.S. derived, rather than BIOS, and all ATX power supplys should be ACPI-compliant. You should not have to be
concerned about this feature.
Line-Conditioning Circuitry
A power supply component that helps control power levels, spikes and surges in
the most unreliable of home sockets.
EMI Filter
This circuitry smooths the fluctuations of incoming AC currents, also known
as Electro-Magnetic Interference - EMI filters are usually found in higher-end power supplys.
PFCC
Power Factor Correction Circuitry...smooths out sudden, initial spikes in power
delivery - reducing amplitude and preventing circuit overloads.
Connectors
There are five main connectors found on the latest version ATX power supply.
1) ATX main power connector - 20-pin, 24-pin, and 20 to 24-pin adapter.
2) ATX 12v power connector (4-pin to CPU)
3) Molex peripheral power connector
4) Floppy power connector
5) Serial ATA power connector
On newer SLI-certified power supplys, you'll find two 6-pin video card connectors.
Know What You Need
When purchasing a power supply, make sure your parts list is all-inclusive...know ahead of time, what you expect to
install in your system. You should also visit the motherboard manufacturer's site, as well as the CPU's. Most of the
products will have specifics regarding power supply requirements needed for that specific component. Unfortunately, you
really won't know how well the PSU performs until it is installed and running your system (hopefully!) This is the main reason we
recommend the most popular brands - power supplys that have shown a duration of manufacturing quality over the years. Those are
as follows: Antec, Enermax, OCZ, PC Power and Cooling, Tagan, and a few newcomers such as SeaSonic and Silverstone are
worth looking into.
If you believe you have found the PSU of choice, remember this: AMD recommends a minimum 350 watt power supply to run
Athlon64 and FX CPU's. To that, add the 30% for power lost to heat, and the subsequent electro-magnetic radiation. Hold on with that
calculator...throw in an additional 40% to 60% for the "potential" inaccuracies of specifications inherent in mass-produced electronics.
Pay special attention to outputs on either single, or dual rail +12v lines. A motherboard, CPU, and graphics card can consume up to
150 watts alone - before hooking up your remaining components. If running an SLI configured board, look for a PSU that is certified
to run that configuration...there's only a few PSU's that lay claim to that!
Broken down, you can look at it this way: An Athlon64/FX processor can use up to 90 watts off the +12v rail. High performance RAM
can take in about 25 watts for each stick of 256MB system memory from the +3.3v line. PCI cards will use about 10 watts each, while
an AGP video card can consume about 50 precious watts alone from the +5v or +12v. Hard drives? A 7,200 RPM drive...about 15 watts
each, taken from the +5v and +12v rail. Finally, but not absolutely is the optical drives...robbing about 20 watts each, also from
the +5v and +12v lines. So you see....not only is the +12v amp ratings of concern, but also the +5v line!
In doing the math...on a system incorporating an Athlon64 (say a 4000+), 2 sticks of high-end RAM, 2 or 3 PCI cards, 1 mid-to-high
end AGP video card, 2 ~ 7,200 RPM hard drives, and a couple of CD/RW or DVD/RW opticals...you're looking at a "base" requirement of 270 to 325 watts. That's for a running system...now figure boot-up loads, 30% for heat and radiation bleed-off, then a 40% safety factor for manufacturing inconsistencies...you've got a power supply in the 450 to 520 watt range!
Modular Power Supplys:
The pins that are used for the modular plugs are not very good at passing current. It's basically electrical resistance between the male and female components, and voltage "drops" are likely. In real world events, they will become loose, dirty, corrosive, and eventually burn. You can figure about 10% less efficiency with a modular power supply.
Now you can understand how manufacturing "tolerances" that are inaccurate by 40% to 60%, can have such a devastating effect on
the performance of your new system. If you follow these simple guidelines, bearing in mind the hardware you will be using, and what
your intended use of the computer is for...then it will be one less dramatic incident when pushing the power button for the first time!
Here's a neat little tool....a bit out of date - that can give you a basic idea of what you'll need in a PSU.
You can apply the percentages above, for an even more accurate assesment of your PSU requirements!

Well, except the CPU, my system has all that you mentioned there (I even have 3 optical drives). And my 350W PSU has been rock solid for more than a year (BeQuiet, = Tagan, IIRC). I don't think a 4000+ needs 100W more than my 3200+ . And that link you posted says that the minimum recommended PSU for my system is 506W xD. Come on.
Oh, and in the place I work there are 6 amd64 with GeForce 6800 GT and 2GB RAM with 380W Antec PSUs. All 100% stable, of course.
I would only go for >400W if I wanted to do extreme OC (with overvolting), or SLI. Otherwise, a good brand 350W PSU is more than enough.

W520 power supply rating vs. performance question

I have had a W520 with the i2820 processor option and the quadro 1000 video for over 3 weeks now. I bought several spare 170 watt power bricks for it, but in one location I kept the 135 watt brick from my W510.
When I moved from the w500 to the w510, when I used a 90 watt w500 brick, the w510 would boot with a BIOS level message that said that the power supply was not adequate and that the machine would be stepped down to a slower speed. The reduction in performance was dramatic and noticable. (The w510 had the 45 watt consumption i920 chip and the more power hungry graphics)
When I use or boot the w520 with the 135 watt supply, there is no message. My benchmarks do not change from those registered when on the 170 watt power supply, starting with the Win 7 system benchmarks for processor and video. Further, the 135 watt brick is cooler to the touch than the 170 watt one under sustained usage (3 hours plus).
The question: given that the w520 in my configuration seems to draw less power than the hot and hungry w510, is the 135 watt supply going to work "as well as" the 170 watt one? As a briefcase lugger, any way to shed weight is valued.
Other considerations: I have no WWAN card installed, and have the CD/DVD removed and substituted with an SSD. The main drive is also SSD, bringing down somewhat the power requirements.

I remember another post, that I can't seem to find now, which refers to a software utility that displays wattage being consumed by the system. This would be quite helpful.
Couldn't that be used to study what is being used, and how much of a power adapter is needed to operate the system?
I am trying to come up with a solution for vehicle usage, and I am afraid, it will have to be a 12V to 120v power inverter with a brick plugged into it.
Another factor will be the amount of power consumed when recharging the internal 9cell battery and the external 9cell slice. Doing this while operating the system with WiFi / WWAN active will increase the demand.

Pavilion 500-205t power supply

So I'm thinking about getting the Pavilion 500-205t, with the i5 4690 and 6 gigs of RAM (I don't really need any more than that for gaming anyway, which is what I'll be using it for). I plan on putting in a new graphics card, but the only problem is that the 300 watt power supply isn't going to cut it.
My question is this: What is the name of the power supply that the 500-205t uses (I can't seem to find it online...) and what would be a viable replacement for it? I would need at least a 400w PSU, and I believe the dimensions would need to be less than or equal to 6x5x3.5 inches.

You are very welcome! Thank you for the additional information.
As I suspected, your computer has a standard BIOS. This means that you will have to buy an older video card. I like EVGA products. I suggest finding a card that you like and contacting the manufacturer's Tech Support (EVGA Tech Support 1-888-880-3842) to make certain that it will work in your computer. This is the best way that I have found to not have to make a return. The last card that EVGA made that used a standard BIOS was their GT 640. Some of theirs do have an update for the VBIOS that allows them to run with a standard BIOS.
Now, for the power supply unit (PSU). I like Corsair products. I normally recommend at least 500W. This allows for future upgrades. A modular PSU is good for smaller cases. You only have to use the cables that are necessary, allowing for better airflow. You should measure the existing PSU and compare the measurements to the one that you choose. All of the connectors should be compatible.

P7-1490 upgrade Graphics Card and Power Supply

I just got a GEFORCE GTX 650TI Boost graphics card. The 300 watt Power Supply on my P7-1490 can't handle it because I need a 6 pin power connector. The 1490 comes with a 300 Watt Power Supply. I need something at least 450 watts. Which upgrade will fit my box. In addition, can the Jasmine Motherboard handle the new graphics card. It does fit into the PCI Express slot.
This question was solved.
View Solution.

Please consider the Corsair CX500, CX500M, CX600, or CX600M power supplies for your needs. Yes, the Jasmine motherboard in your p7-1490 should be capable of handling the GTX 650 Ti. Additionally, you will need to disable "Secure Boot" and possibly enable "Legacy Support" in the BIOS before installing the GTX 650 Ti.

Hello lugnut1204, I checked the specifications for your system and is appears the system shipped with a 250 power supply. The dimensions for this power supply are 5 15/16 inches wide, 5.5 inches long, and 3 3/8 inches tall. Since your system is a MicroATX version, you would be slightly limited to a power supply of the same size as the original power supply.
Here is a link to Newegg where a Corsair 600 watt power supply can be found with almost the exact same physical size as you original 250 watt version. The Corsair power supply dimensions are 5.9 inches wide, 5.5 inches long, and 3.4 inches tall.
If you get a power supply too long, it may interfer with the back of the CD\DVD drives.
You would need to locate a video card that you wanted and make sure the power supply requirements were less than the 600 watt Corsair model. Most of the mid to higher end cards require at leaset a 400 to 500 watt or greater power supply.
