well i manage to get £50 togeather for a psu for a 8800gtx sli build
i seem to be £50 short for my ideal psu corsair gs800 or hx850.
it could be awhile befor i get more money spare like this so what do you say i should do.
hold onto money or is they a good 800watt plus psu that can be had for £50
ty in advance
 
Who told you you need an 800W PSU for a 8800GTX SLI setup, and also on a LGA 775 setup?.. a HX650W will run that without an issue.. check ebuyer.com, you can get an Antec TPN for something around your budget and it's far superior to the Corsair GS.
 
just going off all the 8800sli builds i seen they all been 800+ watt psu's but if the hx650 will run ill try them ty
i was also going off the nvidia recommended sli page

Official recommendations need to account for all the Diablotek/Raidmax/generic trash power supplies out there that can't provide their nominal power.. check this out, and then look at this, if you can squeeze the difference, it's a lot of PSU for the money..
 
lol i was just looking at that cpu and woundering were i could get the extra cash from the fist link helped alot ty
 
Don't know who the OEM for this PSUs is, but that's not a 750W unit, it has four 12v rails with 18A each and a combined output of 650W, so its less powerful than the above mentioned Thermaltake which is a Bronze CWT DSG unit.. honestly, i wouldn't buy any modular, 750W labeled PSU that costs 40 pounds, it doesn't make sense really..
Go with that Thermaltake or the Antec True Power New 650W unit which has a similar price.. and if modularty is not that important you can go with the Antec EarthWatts Green 650W which is a little cheaper..
 
ok thanks again ill save the money
Antec EarthWatts Green 650W is out only has 2 pcie
and same for the Antec True Power New 650W
corsair if i hit lucky on ebay or thermaltake if i dont

True Power New has four PCIe connectors.. and the EarthWatts can be used with Molex to PCIe adapters;)
 
tried molex to pcie befor had a few probs with them ill double check true power new the one i looked at said 2 pcie
 
ah yes i read wrong on the true power 1 6 pin fixed 1 6+2 fixed and a 2 6+2 modelur thats the 650w
damn it depends what site you look at lol god they love to complercate things
 
Just use the adaptors or you will have to buy a bad PSU to get those connections on the new PSU.Look for a OCZ modxstream pro 700 watt PSU are quite cheap and can be found refurbished for even cheaper, ran my i7 950 and SLI 460's for 4 months on one with no problems at all and it is still running fine after over 2 1/2 years use in my gf's PC.
 
what is it with high wattage psu's only haveing 2 pcie connections
OCZ modxstream pro 700 watt looked of 4 sites all say moduler 1 pcie 6 pin and 1 pcie 6+2 pin

cool this helps more then just looking at sites ppl who have used them is the real test

See this is what I look for, then 9/10 times I try and help I get cut down lol, every purchase I made is based of off of my, or someone elses hands on real world experiences not some piece of paper written up by a sponsored reviewer, the OCZ PSU will get cut to pieces because people treat it like a 700 watt PSU, it really is equal to a high end 550watt PSU but is more then enough power your rig will need.
 
i know my last psu i tulk it apart and solderd the 2 6 pins direct to the psu main board
and that was 650 watt psu with out pcie at all ment to have 2 x 12v rails but when open all twlve volts went to a single area so to me that makes it single rail says 2 12v rails at 20 amp each but only one rail so who knows
think name brands are way to go as they have what they say in the box i been thru so many psu's it is untrue

The ModXStream Pro 700W does only have two PCI-E connectors, and it's not a particularly great PSU. The Truepower New would be the best choice.
 
the thing i find anoyying is they use dummy loads that dont care about how stable the signal is and things so they never really is a true test other then first hand think best anser for this noirmaly is find cpu and put polls on for who has had it the longest but end of day always down to money

the true power new 650 or 750 as the 650 from what i found only has 2 connections also

From what I can find, the Truepower New 650W does have four PCI-E connectors.

I don't understand half of what you're saying.
 
sorry i do ramble at times
i think it depends what site you go to to what information is givers i went on a few sites and they were 2 pcie or they were 2 fixed 1 moduler etc
 
yeah scan has the right info 20 less then corsair
dose the single rail multi rail really make any difference
damn it dilivery hikes up the price everytime
 
what i ment to say befor was they are using resisters as loads for testing how much a psu can handle then measure the ripple and noise of the psu that dosent really give us a true clue to what a psu can run in hardware
 
Multiple rails are generally better to have.

Most websites use transistor-based load testers, not resistors. And yes, that does tell you how well they can run hardware.
 
so why dose every one always seem to advize single rail i am gussing each rail would be like haveing a separate psu for each line
 
Most people who advocate single rail PSUs don't really know what they're talking about. A multi-rail PSU is not like having a separate PSU for each rail; it's a bit more complicated than that. Suffice it to say that you really don't need to worry about it either way. Focus on the quality of the PSU, not how many rails it has. For the majority of people, it doesn't make any practical difference.
 
according to the slizone.com page an antec truepower new 550w can be used for sli 8800gtx but your lacking 2 pcie connecters im starting to wounder is wattage means nothing it the ampage that matters
 
Wattage is amperage multiplied by voltage. The more amps you have, the more watts you have. Of course, you have to make sure that the PSU can supply enough watts on its +12V rails, but for a PSU like the Truepower New, that isn't a problem.
 
well from all prices i scene they isent a psu in my price range at the moment so i just gunna have to save another month just sold my laptop to pay for new case and some for psu but not enogth oh well i find average price after postage and packing is going to be £80

The advantage of single rail PSUs is that you don't have to worry about what connectors are on what rail. Sometimes a multi rail PSUs can leave you in a situation where you have enough power in total but you can't come up with a wiring configuration that puts it to the right components. Mostly though if you get a decent PSU the rails will be arranged sensibly so it's not usually a problem.

The downside of single rail PSUs is that if something does short out the overcurrent protection is less likely to shut things down before major damage is done.
 
think it will be more the price for me that says what amount of rails i go for going to be a named brand anyway
