hehe!

i just wanted to understand why the one i linked is bad even though it is 80+

80+ doesnt say anything about the quality and reliabiity of the components and build. If you could find the manufacturer (not just branding sticker) of the one you posted, find indepth reviews of their pus's going over different models over several years, giving them a solid track record of not just being able to construct solid units but also maintain high build quality supply of power suplies to market then you're sorted.

Get a PSU suited to your sytem, PSU's have low efficiency at low power draws so no point going for 750+ watts unless you are definitely planing to go for a dual card setup and overclock.

The reason to go for 'branded' (thats just to say they've been around some time and have built up a reputation) is that there are specialist review sites that take apart PSU's and inspect the hardware and then test the charecteristics of the PSU under various load conditions. Ones being reccomended will have a good track record of providing good quality power supplies. If you're lucky you may also find a review article specifically testing your model which is reassuring.


btw 80+ was refering to efficiency not price. There are good 80+ psu's in the £50-60 range.

thanks

generally.. rules of thumb for choosing a psu

* decent / well known brand
* decent whattage to what suites your computer
* Good Amps per 12v rail
* 80+ certified

I always go for corsair PSU's.. i have always used them, never had a problem with them, so will always use them.. i cannot judge on other well branded psu's as i havent used them, i only use corsair because thats what i know is good and i cannot fault them...

Always remember..... The PSU is the most important part of any computer, regardless of what people say....
You can have all the finest hardware that money can buy, but without a decent psu, it aint ****..

A decent psu can run both types of computers, high power and low power computers. Where as a cheap psu can only run one type of computer, a low powered one....

So far i had Seasonic 430W it was running fine with my setup + 6850.
I tried cheap ACE 750W one just to see how that works. And it was utter **** voltages all over the place.

some of the branded PSU's are generally good and well priced and those are alright but some are hideously overpriced for a low wattage

We need to go back in time and fish out some comedy qtec failure posts from back in the day. The failures that did as much damage to everything else in the system as possible. :D
Might not be the most interesting component to buy, but they are one of the most important!

Theres something to be said about quality components and being honest about your product. Many many suppliers, especially from China etc.. just use one standard design and slap whatever sticker the retailer wants on the casing, so a 230W design from 2001 might somehow be marketed as a 400w today, thats how bad things are. Also, psu specification changed a few years ago, the original specs wanted high amperage 5v and 3.3v lines with not much on the 12v rail, then ATX 2.0 came along and the 12v was the main cpu power rail, while the previous specs called for a good 12v line, it wasn't at the forefront as it was after 2.0.

Many psu companies, once again mostly far East ones still sell ATX v1.3 psus as modern psus, which they are not, hence your 750w psu is probably a v1.3 as it only provides 480w of its power on the 12v rail, your 5 and 3.3v lines are wasted really on a modern system and you may run into power problems depending on the design of the psu.

I think he's trolling.

I suppose a genuine user might read this thread and refrain from buying a rubbish PSU so not a complete waste of time.

If OP is not trolling then he clearly knows much more about PSU manufactoring and quality than us and we should let him get on with it.

Sad thing is, i've met people in real life like this, i can accept when i'm wrong and jog on (happens a lot :D), but some people just like to argue for arguments sake even though theres no merit to their side of the argument.

Have you listened to anything in this thread? You won't have a PC at all if you buy a cheap PSU and it takes your machine with it if it goes. And they do go while being used in gaming machines...

And anyway I'd probably buy a well branded psu have I had £20 or £30 more to splash

Pretty sure someone had linked to a PSU that was under £10 more expensive for a much better name earlier in here...
Absolutely moronic decision to run a powerful machine on a no-name, "free with a box of sugar puffs" PSU.

A decent psu is an investment too, in the last 8 years I've had probably upwards of 20 mobos, gpus and cpus in countless configurations most watercooled often with dual pumps etc.

And 4 psus..

1st a hiper 800w I think, looked great, worrying amount of reports of failures so I moved on rapidly to..

Tagan easycon 580w

Which after reading lots of very good reviews (I was very "into" building then, changing for the sake of it) I switched to...

Seasonic 600w which I sold and replaced with a corsair 600w purely for the hell of it probably 3 years ago.

Once you have a decent psu in the system you really can forget about it which is great.

There's really no need to be spending a fortune on it, just like everyone has said, get a decent, well reviewed, branded psu. The wattage is largely irrelevant unless you have some mega system.

Why get a 750w that has no hope of supplying that power cleanly when you only need 4-500w? Get something that does what you need very well rather than something you don't pretty badly.

It really does'nt look like the OP is paying any attention to the excellent advice being given to him so i will look forward to seeing his next thread entitled "Help, my pc has blown up".

The psu is the single most important component in a pc. Skimping on it is foolhardy to say the least. Ignoring solid, honest, free advice is beyond stupidity. Buy cheap, buy twice (plus all the other components that it takes out when it fails). As a rough guide you should be spending around £10 per 100w for a decent psu.
