PSU Question

Rangler · 20 Apr 2011 at 18:05

Hi All,

Do you think an Antec Truepower 380W psu would be enough for the following.?

Intel i3 540 @ Stock
Gigabyte GA-H55M-UD2H
4GB ram
1 hard disk.?

I brought the above from OC a short while ago and have just got round to building it but it wont get to the BIOS screen it just keeps powercycling

The system and cpu fans spin intermittently then it power loops, ive tried a bios reset to no avail, im just wondering if something is DOA.?

Yes, aslong as you don't add a external GPU

More than enough.

i3 are a lower power CPU with tdp in the 70s. Ram uses just a few watts per stick and a hard drive <10 watts. You probably won't be using half of what that PSU can deliver. I reckon that will not pull more than about 100w in stock trim.

I wonder if the bios reset was successful. How did you perform it?

Something could be dead I suppose. Do you have an alternative PSU?

Going to try psu from machine im on now, 650W corsair.
BIOS reset using jumper after pulling power cable out and leaving it for 5 minutes.

TIA

Hmm

Tried 2 more known good psu's to no avail same thing happens.
I've removed all other peripherals so I'm now only running with the following:-
Motherboard, CPU, RAM, and one hard disk.

I'm wondering if its worth reseating the CPU.? brb.

Clear the cmos?

Got the 4pin next to the cpu socket plugged in?

Rangler · 20 Apr 2011 at 19:22

CMOS cleared with jumper to no avail.

try each stick of ram in turn, in all ram slots?

If you have more than one ram stick (2x2gb), I'd take one out and try again. Then swap sticks and slots.

O.k will try that now, just reseated CPU still no joy, taken video and uploading as i type this.

Rangler · 20 Apr 2011 at 19:38

Wouldn't be too bad if I had a pc speaker to plug in as i could listen to the beep codes

Glad you got to the bottom of it. It's always a relief.

this. you will need a better psu if you intend to get a graphics card

Operation · 20 Apr 2011 at 23:46

It would sill be fine for a basic card. A 5450 would probably be fine while keeping a bit if headroom. Not sure it would be worth it though .

Poppycock! 380w would be fine for a half decent midrange GPU. 57xx, 68xx maybe a 460 or a 560. Good couple of hundred watts spare considering the rest of the rig.
