My power supply

[Ashhow]

Just checked to see what wattage my PSU is and it turned out really bad, it's 350W! I can only afford ATM a 8800GTS and a £70 motherboard, but not this. Is it possible my current PSU will power my E6750 and a 8800GTS on full whack with it? If not will a PSU with 430W run these components on full whack?

As far as I know, most of the decent PSU maker make anything decent below 400W so I have to assume you have a cheap 350W PSU.

Upon installing the 8800GTS you will surely find the PSU don't have the required cable.
If you try to use an adapter cable, you will surely find the PSU giving up a loud pop and may or may not burst into flame.

Don't bother buying new parts if you can't even afford a proper PSU.

If you are going for a 430W, you are looking at something that cost £50 or more. Anything less won't be very stable for your hardware, especially when you are going to try overclocking.

I'll say you will need to spend around £55 to £75
because, by the time you've added all your parts, give and take on the overclocking, you dont wanna be upgrading you psu again in acouple of months due on not enough power
So spend once ,and look ahead in case of upgrades

good brands, Antec, Corsair, Coolermaster,Ocz

Ok i will do that then, i will buy a decent PSU instead of the motherbaord (Now my E6750 will still only run at 81%). Could any of you suggest which PSU on yoyotech will give my enough power for now and possible upgrades but has a decent price?

You should drop to the 8800GT and get a new power supply, a 350w will not power a 8800 series card.

hi there, i would always go for a good power supply in any set up......

as a good starting power i would look at the following -



full details can be found HERE

if you are looking to go sli in the future, then you may need a higher wattage unit...

hope this hepls

Ok thanks everyone, i will buy the PSU you suggested (as soon as my visa electron arrives) instead of the new motherboard, i will get the Motherboard later. Also is it just me or does the PSU you really big, too big to fit in my old case?

Also what makes the PSU so special? I mean there are much cheaper PSU's with more wattage.

What you pay for is what you get when it comes to PSUs.

PSUs from the "trusted" brands e.g. Corsair, Antec, Enermax (plus more) use higher quality components and are built better, these PSUs boast high efficiency and reliability, they hardly ever break down and if they do it won't destroy your whole system.

Cheap PSUs like a 650W £20 job will be around 50-60% efficient meaning it'll only give you around 350W of useful power, plus they don't last as long, probably louder too and can explode taking out your whole system with it.

[Ashhow]

Thanks for the quick reply, now i know why you suggested the one you guys did. If i wouldn't of asked you guys, i might of ended up buying a cheap 800W PSU thinking it would be to good to be true.

hi there, when it comes to PSU's the sizes are pretty much standard, it just the quality of the product that varies...

hope this helps

Yes it helps, thanks.

Cheap psu are false economy and not to mention dangerous.

Not unheard of for them to blow, catch fire etc.

That would be bad enough but when they go, they do not like to go alone they like to take other components with them. So for the sake of £10 -£20 they may well take out your motherboard and graphic cards to boot.

They claim big wattages, but the amps supplied cannot sustain prolonged use.

In simplistic terms imagine running fast, yes you can for a while but you get tired. If you carry on at that pace you keel over. O.K not the same as a psu but you get my meaning.

Manufacturers such as Q tech and the like should be shot, how they get away with it, I will never know.

If you only have 1 or 2 hard drives and 1 optical drive, 1 or2 pci expansion cards then a 400W PSU is more than enough for the 8800GT, 500W is what i'd go for, more than enough..., Enermax Liberty500W is a great PSU

[Ashhow]

I know, i already said i would get the more expensive 520W one; thanks for the info though.

[digital-one]

The psu should be given almost as much consideration as the CPU.

For modern cards and boards, you really need around 550w many people build systems but put in decent kit, then put in the wrong supply - result 6 months later the machine crashes out never to work right again. (power supply quality as stated above is incredibly important your computer has to have a nice even steady flow of power - no spikes no dips - cheap psu's dont provide that basic requirement.)

For a desktop pc your looking around a 520 ~ 650w

I chose this one because it has good efficiency, provides stable power to the components, has enough kick for your needs, and the over voltage protection is fairly decent -its not the best power supply, but you wont get much trouble from it should proide a good stable base till you can get a bigger better monster.


Avoid EZcool, they might be 20 quid, but most only use them for emergency use
