does a bigger power supply help with stability???

[ZUDUKAI]

i am curious about this so i can get the most outta my p4ht chip, it'll be cooled by oil and i want to know if a bigger psu will make it run at a higher clock more stable.

IIRC, no - not past a certain point bigger won't help - but a better build quality PSU will help deliver cleaner power and aid in stability.

What PSU do you currently have?

350, and all my volts are good i don't have the exact numbers on me (not on my computer) but i know my Vcore is 1.5somthing

[CybrSlydr]

What all do you have for your system?

This way we can tell if you're overloading the PSU. Are you currently OCing any? Idlf so, what?

yeah Oclocked, but it's on air, i'm still waiting on oil, running at 2.8, GeForce 6200 OC'd 420gpu 572mem, 3 hdds, and 5 fans. one (or two depending on oil flow) of them is gonna be a blowdryer fan, but it's still 12v and all those numbers are on air for now, (blowdryers work awesome for cooling graphics cards! aside from the noise) **edit** i know i'm not overloading the psu, but i want to know if it will run more stable with a better one.

What Brand and Model # is your PSU?

i'll have to get back to you on that,

but even still, how does that help? will a bigger PSU make a system more stable or not?

Quality PSU will help stability.

We want to load the PSU to 40% to 60% of its rated capacity, not to exceed 70% for continuous operation, as this gives us the overhead necessary for cool, quiet operation and transient responses. In addition to myself, you will find Paul@[H], both Jonny & Wolf@JG & every other PSU guru are in general agreement.

The point of having a larger PSU for stability is in its ability to properly handle transient responses, these are extreme peaks that are usually caused by the GPU or CPU suddenly needing a "quick burst" of power because of something unusual. These are not truly predictable by nature & are are of extremely short duration. A properly sized, good quality PSU from Corsair, Enermax, PC P&C, Seasonic, Xcilo or Zippy will always handle these rare transients properly, becaused they were designed & built to do so.

thanks, that makes sense, thank you. how much more power does overclocked components take on average? ( %? )

It totally depends on the degree of OC, with reasonable air or WC figure 30%, but with LN2 it could be 300%!

lol what do you think i could see from my p4ht 2.6 chip, under oil? haveing the oil passive cooled by "waterfalling" (psu in oil)

I think you should stay away from voltages which can kill you, as the voltages inside a PSU can.

A PSU can go in the mineral oil that we put in computers, it will just get to the same temperature as the oil (which can be bad)

I agree with the other people, tell us exactly your specs and what you have, what is your OC and settings, and the exact model of your power supply. 350W is too vague, I know tons of crap 350W power supplies.

You're supposed to have that memorized, including the amp rating of each rail and the brands and sizes of the capacitors inside. It's just like knowing your family members' names, medical conditions, Social Security numbers, shoe sizes, and favorite cereals -- which of course you do.

I wouldn't cool a PSU in oil because oils can have bad effects on plastics. For example, our solar water heater's pump needs a few drops of oil every six months, and a bit of that oil seeps out and onto the electrical wiring, eventually making its vinyl insulation turn crumbly. So every few years I cut out that bad insulation and shorten the power cord. Inside a PSU, vinyl is used for wire insulation (high voltage, not just low voltage) and the shrink wrap insulation on the capacitors, some which are probably crowded tightly. Below is a link for a chemical compatibility database that lets you specify a substance and see how it reacts to various chemicals:

Cole-Parmer Chemical Compatibility Database

Notice that oils can vary greatly in how they react.

Instead of cooling the PSU with oil, why not just install a quieter fan, maybe a bigger one? BTW, they should be made of plastic, not metal, not even chrome over plastic, because you don't want anything that can possibly short against exposed high voltage (big heatsinks may be at high voltage, but even if they aren't, no metal is supposed to come in contact with it). OTOH don't enlarge any heatsinks that have high voltage devices attached to them. They're usually located farthest from the big bundle of wires for the output rails, on the other side of the big transformer. There's always one such heatsink for the transistors that convert voltage DC to high voltage, high frequency AC, but there may be another heatsink for an automatic power factor correction (AFPC) circuit. Keep any of your heatsink mods at least 1/4" away (maybe at least 3/8") from those heatsinks.

Stay the fvck out of PSU's! Unless you are a qualified electronics technician there is nothing of any positive value to be gained in risking your life by opening one!

asus ps800d-x, p4ht 3ghz (2.6 stock) 1.5gb ram 3 120gb hdd, Giggabyte GeForce 6200. psu is crap, 300, and all it really says is ATX...

A BFG 450W, Corsair 400W/450W or an Antec Earthwatts EA430 430W would be ideal.

If you want to be able to power a nice gaming system (non CF/SLI),
then go up to a BFG 550W, Corsair 520W/550W or an Antec TruePower New 550W.

If you want to prepare for a full blown, OC'ed CF/SLI Game Station,
then a Corsair 620W/650W, Antec TruePower New 650W or a SeaSonic S12E Bronze 650W.

If you want to the "King of OverKill",
then go with an Antec TruePower New 750W, Corsair 750W or a PC P&C 750W.

Best Wishes,
Dave

where would i find somthing like that for around 30? if i even could, if not the cheapest one? all the stuff on newegg is random companys. (that's where i usually get my stuff)

[Nagoshi]

Youll need more money, as 30 does not get you anything in Canuck land, sadly
