Cic 750w psu be enough?

At the end of the day it doesn't take a genius to recommend you to buy a decent PSU and shell out extra £50 quid, and OCZ 500W be right on the cusp of the recommendation.

Personally if I was you I would get a hot / crippled 470 EOL toaster but would pick up a
£140 6850 which will run a sweet as a nut on ur PC. Single 6 pin adaptor overclock it a bit and you will be getting 10% less performance which than a stock 470 which you wouldnt even see.

As it stands you got a 470 GTX and they are power hungry! So power hungry that they are actually o/s the PCI spec in some respects.
 
It says it has 2x PCI-E 8 Pin Connector do they split off to make 6 pin connectors?

as it doesnt mention it has any 6 pin connectors but looking at the pictures of connectors in that link it looks like it may split of to make a 6 pin

were as the ocz psu says PCI-E 8 Pin Connector x 1 (6pin) & 1 x (6+2pin) but im not sure if either of these psu's have a 4 pin atx connector which i need for my mobo

ahh right thankyou for that that clears everything up for me ocuk should probally put that its 6+2 on there website intead of saying its a 8 pin, thats awesome then its got everything i need il get that then :)

It's Corsair, but there's concern over that series in some peoples opinions.

hmm ok ahh bugger i thought corsair was a respected brand thats why i asked im not at home right now when i get in later il do some research and get some other people opinions from here as thats a great price :)
 
The Corsair CX 600W should be okay. Corsair have slightly overrated these PSUs, they've beefed up the 5V and the 3.3V slightly to compensate for a little less 12V power (to make up what it says on the label). There will still be ample power for your rig though.

The problem with firms like this is that most just put a PSU contract out to tender. Thats fine if a decent manufacture is building the PSU but its not always the case.

IMO save up and get something decent, Seasonic, PC Power and Cooling and Tagan all make very good PSU's, and I would take something like a used Seasonic s12 600 from the bay of e, over 99% of the newer budget models.
 
Hi Renni,

Glad to see you've gone for something a little more solid, the TX are generally good PSUs.

People, as Skyrocket pointed out, often do go OTT on the PSU in terms of requirements, and sometimes thats down to ignorance; you have to remember that when ATI and Nvidia are recommending a wattage, they're usually doing it with a ***tty generic PSU in mind, rather than a well made one.

BUT, running a power supply on the cusp of its capabilities not only lowers it's life span and efficiency, but traditionally cheaper power supplies are not as well equipped in terms of protection.

What this means is that a decent quality 500w power supply may not only have a longer lifespan providing 300W of power, it may run more efficiently/cooler/quieter whilst doing it than a cheap '600W' PSU which can only provide say 350W consistantly (peak vs constant), but when/if the PSU fails, its more likely to have protection built in designed to stop it taking out other parts of your PC, whereas the cheaper one is more likely to surge and damage other components.

Not a hard and fast rule per se, but consider the PSU the backbone or heart of a system; if something is wrong/not up to scratch with the ticker, then it can do a lot of damage to the rest of the system, and the PSU is one of the few pieces of kit that if it dies, is known to take out other bits of kit with it.

A lot of people can get by on poor PSUs, because most PCs out there dont run high end or demanding hardware, or aren't really stressed out (internet usage etc), but as you want to run something like a GTX470, its not worth taking the risk, as the 470 WILL pull current at load.

Its just not worth taking the risk - and take it from someone who's had a PSU explode in thier face...its not pretty.
 
Thankyou for all the knowledge ive recieved from this thread, thats what i thought. No point spending all that money on a gpu and skimp on the psu for it no be able to handle it and potentially kill my new gpu so i decided to go for the more expensive psu option for peace of mind, thankyou for all of your imputs and advice given its all been taken onboard and now i know abit more about computers and learned a good lesson- Dont skimp on the psu!
 
Should also say that a lot of the el-cheapo, generic-brand PSUs are very loud. The Corsair TX650 in contrast should be very quiet. It's a good choice, and [I can't read - how do I added VAT?]
