Someone please back me up here

I've just had a row with my boss - we have been supplying customers with P4 machines in cases with 145W Power supplies !!!!!!!!!

Lo and behold we are getting PSUs failing left right and centre

He says you can run a P4 machine fine with a 145W PSU, I say otherwise, but he's convinced they just must be a faulty batch

AAAAARRRGHHHHH

**Howard** · 30-10-2003, 10:50 AM

Can you even buy cases with PSUs that weedy?

Christ!!!
Your boss is a berk

**SilentDeath** · 30-10-2003, 11:02 AM

lol. i think that the psu would eb continually stressed and even if it does somehow supply enuf jiuce, it wont last long.

lets assume some things:
cpu uses 70w
ram uses 20w per stick, of which theres probably 2...
mobo uses 30w
gfx card uses 40w
theres also 4 drives in this pc, which would total about 10w not including starting current which could be 6x more but only for about 50ms when drives spin up
then you have all the fans... could easly total to 5w

thats about 195w, ive rounded the numbers up a bit, and some of them are just guesses based on heat output. i dont know how much heat a p4 makes, but my 1700+ makes about 70w in its overclocked state (2.2ghz)

for an average 200w load its best to use a 350w or bigger psu, try to aviod qtec branded ones, as they are either named differently to what they are rated for, or just rated wrong.

i find unbranded 350w psus fine, i wouldnt buy an expencive brand psu unless i had a lot more load (if i was running a small pelt on my gfx card for example) but antec seem to be the best in other ppls opinions

are the 145w psus mini ones for stuff like HTPC's or just very very old normal ones?

Skii which computer company do you work for, just so i know never to buy from you ever!

lol

Don't blame ya

Right - apparently these cases are from ACME

http://www.acme-technology.co.uk/acm606.htm

Further investigation - the machines we supplied were Celeron 1.7 Pcs, and we were supplying them in 145W desktop cases !!

Words fail me

**TooNice** · 30-10-2003, 11:25 AM

o_0

And I thought my PSU was as weak as they come (200W?).
I reckon its pretty stretched as well - despite my PC being a P2
2xHD (one 10k SCSI), 2xOptical devices, 5 fans (I think) etc. etc.

And now that I know they exist.. I still find it amazing that a P4 can boot with it!

**SmileyUK** · 30-10-2003, 11:39 AM

Its down to the quality of the psu too, dont forget they probably only have onboard vga, single hard disk so there isnt much draw on the psu really but 145 is pushing it.

oh and acme cases are terrible....but even they recommend their psu is 200 for p4.

Do the sensible thing and dont buy acme

**daniel_owen_uk** · 30-10-2003, 11:40 AM

145w is a very small psu, not too sure you customers are gonna be too happy.

One word, RECALL!!!1

**SarG** · 30-10-2003, 01:08 PM

I actually shuddered at the sight of that case.... eww

145W is definatly not enough for what they are being used for. My cousin had a compaq pc that had a 145w psu (Low celly 700? 256mb ram 1 hdd 1 optical drive) i thought it was low for that but them being used on a P4?? :shock::eeek:

**Zak33** · 30-10-2003, 01:44 PM

Vauxhall sell a Corsa with a 1.0 3 cylinder......its not quick, BUT we further nuke it by putting a taller gear box on, AND an Automatic gear system, AND taller ratio tyres to save petrol

It does 4 zillion miles per gallon, but you must live at the TOP of all the hills in the world.....and always wanna go down.

And that is the same thing exactly. It aint right.......our JOBS aren't right.....cos WE KNOW and the superiors DON'T know anything

Gonna go cry....if ya wanna join me Skii, I'm over in the dark corner

**dannyboy** · 30-10-2003, 03:37 PM

Your boss does indeed sound like a pleb.

**Platty** · 30-10-2003, 06:03 PM

145w

Didnt know you could still get them. Definately a bit dodgy IMO.

**Stringent** · 30-10-2003, 06:15 PM

ACME? Aren't they the clowns who supply the Cyote with stuff to catch RoadRunner?

That what I was thinking

Seriously though, Skii if your boss thinks it's fine to run a P4 system on a 145W PSU, you should ask him if he is in the right job.

**Lexeus** · 30-10-2003, 06:32 PM

Maybe you should show him that web page, as the case company says you need the 200W to run a P4; but do youthink he is just trying to save a few £££'s ?

**joshwa** · 30-10-2003, 06:34 PM

The Dell SMT (optiplex) PCs, with P4 1.8ghz, 256/512mb, 1 hd, 1 cd drive, motherboard with everything built in, come with 250W power supplies.

150w in this case definitely seems like way too little.

that page says it all: "150w for P3" "200w for P4" you can't get much clearer than that!
