I assume its the Seasonic S12II 520W unit? I would pick that one over the other units listed, it got a 9.7/10 from jonnyguru.

I'd get the cheaper of the Neo or Seasonic. If both of those are to expensive, then the BP500 or Silverstone unit would be my next choices.

As a general rule, Thermaltake is going to offer lower priced units with higher wattage ratings because they are not high quality. They have some nice power supplies at the lower end for a GP pc, but not highly recommended for a gaming rig.

The Antec NEOs are nice power supplies. The seasonic is a good PSU, but as you say they can be a bit pricey. I am an admitted Antec fan, but check the reviews for yourself.

The neo actually is priced quite well and its about 80$ au . So i can go for that . Seasonic on the other hand is about 120$ . So u guys think that the Neo will be a better pick than the TT even tho is has a high Wattage.

Because with my last psu , the cpu fans and case fans would come on but the system wouldnt boot . I dont want that to happen again

There are several things to look out for when buying a PSU. First, how much usable power is there? Modern systems basically get all their power from the 12V rail. I would rather own a 520W PSU that can output all 520W on the 12V rail then a 700W PSU that can only do 460. The next thing to consider is can the PSU actually output what it claims it can. Jonnyguru had a great reviews of a diablotek (?) 1050W PSU that couldn't output more then 600W. If you bought that unit to power your SLI GTX480 rig you'd be very disappointed. The last thing to consider is how long the unit will last. I cheaper PSU probably has cheaper parts inside of it, and it might not last very long past its 1-3yr warranty.

What makes you think its the PSU? A bad motherboard could cause that as well.

Alright awesome , i think then ill go for the neo eco 520 .

Well the mobo light comes on the fans start and even the casing light comes on . But the system wont post . I need to remove the ram and clear the cmos and all and just wait abit for the comp to start . Can it be the mobo ?

whats with people and thinking thermaltake are no good?? have you ever used one? I have used many and have never had a bad experience. They generally use good quality caps and components that will last, judging from my own experience and reviews.. I think the 700w rating is PEAK though, and continuous is 600w, thermaltake ratings can be a bit overrated.

Good companies won't do that. They'll say 700W but set the OCP to allow 700 or 750. My problem with TT is that while they have good lines, they have bad ones to. Its natural, all companies do. I can't only memorize so much, so I tend to avoid TT or suggest TT to others. I do know their 775XT is a good one. But other then that I'd just be guessing.

I have to disagree with you, thermaltake is one of the leading brands of Power supply, Ive had a Thermaltake PSU since 2007, and its rock solid. You literally cant hear it its so quiet and not one has it caused any kind of problem, its very efficient too. My friend has had a Thermaltake PSU for nearly 10 years and never had a problem with it.

well the thing is i know for a fact that TT have come out with some really good psu's . Some of their psu's r really good . The question here is if Litepower 700w is any good .

Have any one here used a litepower or knows any one who has used one ? to give a recommendation ?

It's good depending on what it's used for, In you case I would say it would work fine.
However if you went with a newer graphics card or planned on OC'ing I'd recommend a better quality, IE corsair/silverstone etc modular power supply.

well am going to oc the e7200 of 2.56 to 3.8 and the graphics card will probably be at stock, the ram will at 1.8 1066 . 5-5-5-12 .

do you really believe the e7200 will get to 3.8ghz on air cooling and be any sort of stable? That would be really pushing that CPU and it will probably burn up in due time with the voltage needed for that overclock. I mean, good for you if you dont mind risking this, but I would go for a lower overclock.

The vcore of 1.25 is good, but the load temp is a bit high. What HSF are you using?
