£900 spec please :)

I can't say I've ever heard of them and the quick search I've just done seems to indicate they might be a bit cheap. I actually meant what are the rails supposed to offer? e.g. 12v - 25A, 5v - 42A or whatever. Does the PSU feel reasonably weighty to hold? That is often a rough indicator of quality. :)

well i'm not sure about the amps and stuff, but i'd say it weighs about 1KG, but it feels fairly lightweight, tbh I've never held any psu's in my hand before so i don't know.


surely a psu's a psu's just means it may not last as long, right?
well i can't take it back now. it can't do any damage can it?
i mean suerly most pre-made Pc's only have fairly generic psu's right?

I really wouldnt stick some mickey mouse psu in a build with a quad and a GTX :)

the lower the quality of the PSU, the less stable the power output is. you will not be able to OC as much/at all with a low quality PSU.

you might get random reboots/bluescreens if its really bad.

often low quality PSUs don't have protection circuitry either, which means that when it goes *BANG* (which they are MUCH more likely to) it can take the mobo, CPU and GFX card with it.

Prebuild PCs, the likes of dell and HP, while not having PSUs made by corsair or OCZ, tend to have PSU's of unknown brand yet high quality. for example, the high-performance Quad-Core dells only have like a 350W psu in them (or something around that)
 
so bascially if it does have preotection circuitry for when it goes bang, it should be ok? how do i know weather or not is does?

thanks.

If i post post some pics of the PSU will it help you to judge it's quality?

much more likely to go bang or much more likely to take out cpu etc...

The guy in the shops theory was that it will just slowly detierate and decrease in power output, which is why i needed a 650w to last longer. Are you saying thay can just randomly blow up? I thought they just worn out over time.

Sort of right. PSUs do become less efficient over time but that isn't a good reason to buy a cheap 650w when a good 500w would be more stable and last at least as long although it costs a bit more.

Any PSU can randomly blow up, that is part of being an electronical device but a good PSU will not take the rest of your PC with it, a cheap one might.

1kg is fairly lightweight in PSU terms, I'd generally expect a good 650w to weigh at least half as much again but this is more of a rough approximation than a hard and fast rule.

You don't actually need to have a clue about the amps but on the side of any PSU should be a label listing the 12v rail, the 5v rail and 3.3.v rail amps so if you could tell us them then that would help. :)
 
would a surge protector help?

ok here are some pics of the unit and it's packaging etc...

Thanks, it was only the second last image I really wanted. The 12v1 and 12v2 rails don't look too bad, when the rails combine you probably have 36-38A usuable power which would be decent enough. Winpower are ok as an OEM for PSUs if memory serves me right so maybe the PSU will be fine after all. :)
 
really, so does that mean it has protection circuits, and won't take my hole system down if it does blow?

btw it was only £30.

thank you for all you're help and time btw :D

right so if the psu issue seems to be out of the way now, is there any advice you can give me for this because it is my first build. The parts will be here by tuesday :D I can't wait lol.
 
I'd use a surge protection strip anyway regardless of the quality of the PSU, Belkin do several models and offer a guarantee on equipment connected up to the value of £X (depends on the model bought). It won't necessarily do anything much but it doesn't hurt either.

As to building itself, there isn't too much I can give in the way of advice other than take your time, don't force anything too much because it will only go one way which should be obvious. If you are unsure then post back and people can probably help.
 
alright cheers mate, I think I should be alright, my dad's going to help me a bit.

I so excited lol, my current PC is like 5 years old, it's gonna so much quicker :)

thanks again for all your help (Y)

could someone just clarify the point i put in bold please. Mine is a winpower/trendsonic, is that likely to have protection circuitry?
 
trendsonic 650w modular psu, atleast on the packaging, the psu itself is branded Winpower, does this mean that it is the same as the psu stated above but just the high output rated model?

and is overpower protection like surge protection?
