my brothers pc,he has socket754 amd 2800+,bfg 6600gt OC,and 2 hard drives,i have some specs on PSU,and wanted to get some feedback,and i will go into more detail as i ramble on,
for example u have
min max min max
vcore1 1.55v 1.63v -12v -11.54v 0.56v
vcore2 2.56v 2.58v -5v -5.16v 2.03v
+3.3v 3.12v 3.26v +5v 1.51v 5.78v
+5v 1.26v 5.94v vbat 2.85v
+12v 11.78 12.03
*note to see images good,u will have to hover mouse over image then click maximize thing at bottom right.

PSU link
http://www.geeks.com/details.asp?invtid=AP500W&cpc=SCH

mind that these are while folding using 75percent cpu usage,id do 100% but keeping temps down to 108F,otherwise idles at 80F,his power supply is a A power 500watt max combined watts,was wondering if hes risking anything,as i have read PSU are like the Heart of machine,hes played CS source and SCell CT,no probs,been a steady system for last 2 or 3 months,i havent seen a crash or anything,but i was interested in looking into,considering the money in his system,i think i have a link to the PSU,and ill include link with pic of speedfan monitoring.if u notice lots of fluctuation on voltages.im Skeered.thx guys any help will be absorbed and appreciated.
 
Sorry..... what exactly is your question again?

At a minimum I would say the PSU linked was sketchy as far as quality in all likelyhood.
 
well you take all software voltages with a grain of salt
they are pretty good a relative values
but notorious for being inaccurate at definative values
so all those ranges (or just some of them ) could be higher or lower than reported
the fluctuation range and the values listed however are in spec
as far as vcore goes thats more the responsibility of the mobos VRM (Voltage regulation modual)

that A Power 500Watt is for starters an oldschool ATX12V v1.3 supply with only 17A on the +12V rail
http://www.cputopia.com/cputopia-a-power-atx-dual-fan-500w-power-supply.html
and I personally wouldnt trust it to power a windup toy till I knew what its a rebrand of
its could be a fairly decent supply then it could be junk

that said "junk" supplies vastly outnumber "good" supplies
and the differences between them are the breadth of thier operating range under adverse conditions and how stable thier crossload profile is for what your particular config is drawing

since its been powering that config without issues, the question becomes one of peace of mind by upgrading to something with power to spare and that youd have a higher expectation to protect components in the event something goes wrong (brownout or surge)
obviously the typical load on the supply isnt exceeding it capacity, but it may very well be close

http://takaman.jp/D/index.html?english

if so it could wear on its ability to maintain that indefinately
another variable is that as the temperature gets hotter this summer its capacity is going to drop (if the room ambient isnt controlled)
the worse case senerio is what we employ to guage a PSU choice
but I lack both the full config and more importantly better info on that make

I'll see what I can learn about A Power

Well for 17.95 for a 500w supply I would guess what you learn will be that is not such a good supply. Just a hunch. ;)
 
what the windup toy analogy wasnt strong enough? :p

and to point out the unstated but obvious
most of that capacity is unused in a modern config that employs the +12V rail to power the CPU
(or in any reasonable config for that matter, likely real needs are around 200Watts average)

what Im wondering is if your brother has an older board that is using the +5V rail to power the CPU

is there a 4 pin auxillary +12V mobo connector on that board?
