Whats the difference with all the PSU's?

I guess it's got a lesser chance of blowing and taking parts with it. You get what you pay for, as they say, and I've read a few times that if you're going to go for a really budget part on a new build, make sure it's not the PSU.
 
Also the cheapo PSUs will probably cripple under heavy load. They don't even reach their rated power either
 
its a bit of a generalisation but:


the expensive psu will:

1) actually deliver its rated wattage
2) be built with far higher grade components (read as: longer life)
3) be far more efficiant (run cooler and use suck less power from the wall socket)
4) run quieter as a result of running cooler
5) have a longer warrenty
6) have more cables
7) possible look prettier :p


so yeah. as far as psu's go, moeny talks. dont skimp on one.
 
Put in simple terms the £100 PSU is likely to use better components and be able to supply the rated capacity, a £40 PSU is more likely to go on the maximum output rather than the sustained capacity. This isn't always true but more often than not the price and weight of the PSU has a bearing on the quality. There are also sometimes additional features such as modular cables or the ability to combine the rails on more expensive PSUs. :)

I mean, ok you pick up 2 PSU's that supply 600w each. ones £100+ ones £40. What does the first one do better then the second?

One powers you pc underload and with overclocking


The other blows your PC up :eek:

What's the difference between a 2 litre Yugo engine and a 2 litre Volvo engine? Same principle.

In in the Q-tec's case:

At about half its rated power, around 320 watts:
Drop from 12 volts to 11 volts on the 12 V line making pc unstable...

At aroudn 400 watts output:
Start screetching when really under stress, also for 400W output it draws 1.2 kilowatts from the socket...

At its limit (around 450-500 true watts) it blows up with a bang, possibly taking down half your pc components with it....

This applies to a cheap psu called the Q-tec 650w triple fan

then there are rebadged psu's on the market too.

whats the difference between a 2.0litre VW engine and a 2.0litre seat engine?
 
Yeah, in the July intel price drop im looking at upgrading from

p4 3.06 @ 3.8
DS3
2gb crucial ballistix ram
x1800xt

to
E6600
keep the Ds3 and ram, and im looking at upgrading graphics card, unsure yet but will be either the 2900/8800. Im aware these may use more power then my 1800 so looking at changing my PSU from a 400w up to something better.

depends what engine and car tbh


corsair 520w would suit u down to the ground btw
 
lets calculate how much power a high end system would actually need.

lets say overclocked quad core c2d
4 sticks of ram
mobo
x2900xt
xfi sound card
2 hard drives
2 dvd drives
4 or so fans

what sort of wattage would said system really require?

the gfx card they say takes 240w, so what do the others take?
 
i have a corsair hw 620

im running

2x 8500 balistix @ 1200
10 x 120mm fans
1x 80m fan
2 x liang ddc ultra pumps with plexitops
4x sata hdd's
1x ide hdd
conroe e6600 @ 3.9
8800gtx @ 692/2200
6 cold cathodes
8x led's
sb soundcard
my mobo is now a p5k deluxe wifi

that setup probably taking up around 350 odd wattage.

Lol and the rest... Probably more around 500-600 according to the PSU calculator..?

LOL not likely, unless you reckon 4 hard drives and 10 fans would use 300 watts LOL




ps: psu calculators are bull. dont bother with them.

paul: hows thast p5k?
