What PSU Do I Need?
October 2nd, 2018
I cant provide much info apart from im on Acer Aspire T671 and on 250W PSU
I want to upgrade ready for the new nvidia card or 8800. I know i’ll need 600-700W for this, but which one will work. Some screens of what my specs are so u know what will need to be plugged in, i also have PCI-E x16 and x1 and 2xPCI slots on my computer and 160gb sata drive
I need UK links only as thats were i live, im willing to spend whatever. So thanks and please help
my mate bummed this one when he bought a �60 psu which didnt have the right connectors for his nvidia 8800
his psu only had sets of 4pin power connections, and didnt have the 2 6-pin connectors you need for the 8800.
he ended up payin �100+ for a 1000W psu.
ill try n find the product.
of course the machine he built was mental and needed 1000W,
follow this link for some more specific 8800 psu support:

it really depends on what card u get, but you dont need an 1000 watt psu that would be an waste of money, get an decent 600watt psu then from the respected brands like Enermax zalman tagan, those should have the required molex on it
, basicly the “W” sign on the PSU means nothing when it comes to cheap PSU.
My best advice to get 400W – 500W from a decent firm, 400W will do enough but get something like Enermax / Thermaltake / Antec / OCZ / Corsair and try not to get their cheapest PSU, get something around 60$ and up.
Easiest way to test a PSU is by their weight, the heavier the better ( might sound funny but true ).
I’ll just give you an example.
I’ve an Enermax PSU 435W which at the time cost me 100$.
My Specs as following ( I’m not writting full info as this doesn’t matter )
Gigabyte DS3R MB
Intel E6550
4GB RAM DVD-RW
500GB HDD + 320GB HDD + 160GB HDD
GeForce 8800GT 512MB
120mm fans 5 units + Zalman CPU FAN
All that runs on the PSU perfectly… I hope you got my point no need in highest “W” only a decent PSU with a 400W – 500W.
P.S.
I’m work in a computer shop and I see too much cheap PSU die
*PSU – Power Supply Unit
hmm maybe i didnt make my post clear – he bought a 1000W psu cos his computer was a beast.
Above posters are right, you wont need that much, BUT make sure you have 2 x 6 pin connectors, or expect to return..
Remember this simple equation. Bigger = Better
Everyone has more and more things running on their PC these days.
Remember this simple equation. Bigger = Better
Everyone has more and more things running on their PC these days.
Bigger = Better, true.
Bigger = better = more expensive also true
I don’t wish to argue or anything hehe just saying that not everbody has money to pay for bigger when they don’t have use and will not have use in it in the future.
Looks good but how do i know which one to buy, like what are the right connectors, if you could do some research on my specs and find what can connect to what. Then link me to the PSU i need. Doing this may get you a lil surprise and in my friendship book xD
ya see this:
8800GTX SLI ready 'no adapters needed'
700w or greater, 56A or greater on 12V rail(s) combined, 4 or more PCIe connectors. Note: for the PCIE connectors listing '6' refers to standard 6 pin pcie connectors, '8' refers to the new 8 pin pcie connectors the ATI HD2900XT card uses - so ATI HD2900XT crossfire users that are overclocking choose a PSU that has at least 2 8pin connectors as well as 2 more available 6pin connectors (typically 4/2 configuration).
you need to look for a psu with the 2 x 6pin connectors. thats it really.
Enermax Noisetaker – Something like I have, that’s a 420W
http://www.newegg.com/Product/Product.aspx?Item=N82E16817194012
Connectors
1 x Main connector (20+4 pin)
1 x 12V(4+4pin)
4 x peripheral
4 x SATA
1 x Floppy
2 x PCI-E ( 2 X 6 PIN )
That’s something minimum I would suggest.
or something like this one
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139004
Connectors
1 x Main connector (20+4Pin)
1 x 12V(4+4Pin)
6 x peripheral
6 x SATA
2 x Floppy
2 x PCI-E PCI-E Connectors 1 x 6Pin
1 x 6+2Pin The good thing in the CORSAIR PSU that the PCI-E Connector is 6 + 2 which is used on some video cards.
Hope this was helpful
I have a 600w ps and it works fine with 8800GT, mines a coolmaster one.
to continue on that bigger better ~love~, it is better that if you have an certain usage of watt that your psu is close to that consumption lvl. the psu is then the efficienst with the power.
nothin wrong with having room to expand though.. but yes probably is less “wasted” if its closer to your requirements.
I bought a COOLER MASTER eXtreme Power RP-550W, and it works just fine. My specs are:
MSI K9N SLI platinum
AMD 6400+
2GB RAM
DVD-RW
300GB HDD
GeForce 8800GT 512MB
The PSU is very reliable, very good ratings.
If you have one 8800GT a 500-550W will work, although has a 420W.
If you plan to have 2 8800gt for SLI, you need at least 600W.
This is what i bought:

550w is ok try CoolerMaster Real Power 550 watts
1. Support dual core CPU & dual CPU.
2. Compliance with the newest Intel� standard ATX 12V V 2.01
3. Compliance with the newest SSI standard EPS 12V V2.1
4. Compliance with nVIDIA SLI specification.
5. Super silent operation with intelligent fan speed control (< 23dBA)
6. Power consumption management by human computer interface (HCI)
7. PCI-e connector satisfy high end graphic card requirement
8. Support +12V1, +12V2 and + 12V3 outputs for higher power usage
9. Green power design to meet energy star and blue angel requirement
10. More than 75% efficiency at typical load operation
11. Higher reliability (MTBF > 400,000 hours)
12. OVP / OCP / OTP / OLP / Short / Full protection
13. Active power factor correction (PF > 0.99)
14. Real power capacity satisfy high-end system operation
Go grab an Enermax ELT500AWT. It has modular cables and supports SLI should you feel so inclined.
By the way, if you buy an 8xxx card you may find it will bottleneck your CPU. It might, might not. I have no idea. Just thought i’d let you know. It happened to me once. I bought a 6600GT and used it on a Celeron D 3.06ghz, and on CSS for example, I now get 100fps with my new CPU, but before I got 40 because the CPU was bottlenecking the video card.
I would say, make sure it has a 24 pin ATX power connector on it as many newer motherboards now require this. Many will come with converters so that they can connect to 20 pin ATX power connectors as well. My Current PSU (Tagan) that I purchased over 3 years ago came with a 24 pin ATX connector as standard, with a converter to allow it to connect to the then common 20 pin ATX connector. It was certainly well ahead of it’s time. It is extremely heavy for a PSU, I did weigh it before installing it but that was over 3 years ago and I do not remember too well what it weighed. It might of been close to 3KG, certainly over 5lbs.
Make sure it has at least one 6 pin PCI-express power connector. It might be worth having 2.
As many SATA power connectors as possible.
Some Molex, but not as many are required now, mine has 10 I believe, you will not require that many now.
Most makes should fulfil these requirements now, but just check to make sure before purchase.
Having connectable power cables would be nice so that you only have to connect the power leads that you need as it will make the inside of your case tidier and air flow will benefit from this.
The 12 volt power rail is the most important now so it would be good to have multiple 12 volt rails.
PC Power and Cooling is the ultimate maker of Power Supplies and they make the benchmark PSU’s by which every other PSU is judged. PC Power and Cooling has now been purchased by OCZ’s.
You cannot beat reading some in depth reviews, here are a few recent ones. It might be worth looking for a few more reviewed in 2007. Finding one that maintains the voltages at high loads is what you need to look for.

good point…
Thanks for the help everyone, i think im on the right line now – ill update if any more help is needed, i only have 1x PCI-E slot so SLI isnt an option
just make sure you check specfic details about all your components (down the the power connections of your future gfx) – and you should have no problem.
possibly think about buying from a retailer you can visit – that way if it goes wrong you dont have to mess around with online returns (which are a pain in the a*** imo)
i have Acer Aspire T671, so i think i have Mini ATX, which power supplys will work with that, i need 600W + and PCI-E/Sata Connectors
