New Rig: Power Supply question. SUPER URGENT!

[leousb]

Hello everyone, been reading a lot but have not come to a conclusion:

PowerSupply TAGS comparison

My new rig:
E6400, eVGA 8800 gts 320Mb, 965P-DS3 Gygabyte MoBo, 2 harddrives, 1 pci wireless card.
(old rig: MSI K8Neo2 platinum, ATI AIW 9800, 1 harddrive, 1 pci wireless card)

Asembling my new rig, after all was ready realized that my old Powersuply had a 20 PIN config, and my new one was 24 PIN.

Went and bought a new Power supply (550W), got this one cause it's the only one available where I live (just no name brands), BUT read somewhere that in order to run a system as my new one I needed 12V rails with 26 AMPs, and if you see the tag, max AMP for the 12V is 22A, I don't know if this is true.

Can some one confirm that my new rig will run fine and be safe with this new PS, (don't want to fry it make it last for 6 months or a year)??? Checking out the old one, you can see that it was 400W (500W peak) and everything ran just fine . . .


BTW I'm desperate to turn this thing on already! Help please!

Thx everyone!

Turn it on and see if it does.......if it's completely underpowered, as I suspect it probably is as that 22A rating for the +12V rail is probably the MAX it can output, the rig just won't turn on.....maybe you'll see some fans spin up but it won't boot.

Not good news so far, But If it actually turns on, will it be harmful for the components???

My previous rig ran just fine with 17A on the 12V rail . . . just trying to make some sense out . . .

 

[leousb]

any more opinions please???

I might try to turn it on but would not advise you to continue running it using that power supply anyways. Order a nice one online then try it, no point in risking ur new system on a cheap pos PSU.

Unfortunately, it's impossible for us to tell if it will work.

A quality PSU specifying 22A on the 12V rail is night and day from a cheap no-name PSU specifying 22A on the 12V rail. The cheap ones use all kinds of tricks to up their reported specs, whereas a quality one that only reported 18A could probably run your "26A" system w/o a problem.

Well, turned on the thin, everything seemed normal at first, but got nothing on screen, No post whatsoever . . . removed the mobo battery for a couple of minutes (read somewhere this resets de cmos) and turned it back on, but nothing . . . Read on the forum it might be due to high voltage required by some memory stick, so will try tonight with some cheapo memory again and see . . . any more suggestions are very welcome . . .

Power Supply Fundamentals <-- Reading that should anwswer your amp and wattage questions.

I will also say that running a generic PSU is just asking for trouble, get a good 350 watt Forton-Source, Seasonic, Enhance or Zalman.
