Is 150W enough??

[AMDCursed]

I have an abit st-6raid, a celeron 1.3, a hard drive and the usual expansion cards. Will 150watts be enough?

[tony_j15]

Maybe... But to be on the safe side I dont reccomend any PSU under 300 watts.

[AllGamer]

man where to you dig up that old AT PSU from?

150 w

i can't believe they still sells it

it's barely enough dude, yes it'll work, but you'll get random reboot

:t

That wont work with the mobo, I doubt it. That board is a ATX board.

[AllGamer]

Oh yeah thanks for pointing that out

i totally forgot to finish my sentence :p

i wass typing that stuff when i was in a phone call :D

Not only no, but H E Double Toothpicks No. You cannot run a stable system on that amount of power these days.

Also, it has to be ATX to even fit a current motherboard. I have seen ATX PSU's as low as 145W (In Gateways and the like) but I wouldn't use one.

[AMDCursed]

The PSU is actually a DC-DC PSU for automotive and marine use....

[AMDCursed]

and yes it is an ATX

[Kruzin]

Not a chance.
150watts will never run a stable system.
Even the cheasiest old celeron400 e-machines we have at my school have 200watt supplies, and I have had power issues with those whenever I try to add extra cards or drives.
I will not use anything less than 350watts in my own systems.

In case no one has noticed, the trend is back to low wattage power supplies running some pretty up to date stuff. I recently built a very nice running unit on the ASUS Terminator P4 bare bones. It runs a P4 2.0A, 256mb DDR, 40 gigger Maxtor 7200 RPM. ASUS 40x CD-RW, ASUS 56x CD-Rom. Using the onboard Sis graphics chip, on board LAN and a PCI card modem, you would never know that the power supply is rated at 165 Watts. It is rock stable, fast and has that silk smooth touch that only quality component can produce. So much for 300 Watts being required.

I'm sure it runs well, and congratulations on building a system that meets your needs on such a small PSU.

However, for many Sysopt members that wouldn't be a viable option. With the exception of a PCI Modem, it appears you are using onboard everything. You mentioned video and lan as being onboard, so I presume sound is too. Right there you've saved a lot of power draw.

I'm going to say that it's unlikely you're a hard-core gamer, at least on that system. So you probably aren't stressing the processor that much most of the time. You might see problems with sustained 100% CPU usage, and you certainly don't have enough power for a dedicated gaming video card.

For a basic surfing/wordpro/email box it's probably fine. But it won't stand up to a lot of hard use.

Add anything more and watch your +12v and +5v rails tumble.

The PSU is being stressed right now, even though it works perfectly.
