Is my PSU up to the job?

Sweetloaf · 26 Jan 2009 at 12:30

I'm going to be running

Q9550
4Gb OCZ Reaper
9600GT
1 SATA Optical drive
3 x 250GB SATA 7200.10 drives
2 x 120mm fans
Arctic cooler CPU fan
USB powered Axiom 25 midi keyboard
USB mouse
PCI soundcard with breakout box

My current PSU is a 4 year old Tagan 480Watt

It's never missed a beat but not sure if it will handle the above spec.

seems to think a good 451W power supply will do the job but due to improvements in technology I'm not sure if my PSU counts.

Any thoughts or real world experience?

I ran my rig (see sig) on the 450w earthwatts that came in the sonata 2 with 5 hard drives amongst other things

I would say yours is fine

Mind if I ask why you bought a Corsair 750W then?

I could never overclock the cpu and get a stable system for months on end - I thought it was a power issue.

The psu was 2-3 years old and my brothers and a friends had died.

I run the rig in sig which includes a few pci cards, 3 usb devices, a 120mm fan a 140mm fan, 5 hard drives - Which I knew must be pushing a 450w to the limit. Your system is no where near maxing out the psu though

I decided with some Christmas money that with a new hard drive I would get a psu while I had some available money. Was going to get a much less powerful one but the 750w was on offer (since new year it has risen 20quid as well) and was the same price as the 650w. A psu has no impact on performance but it is something that needs to be good enough and I don't plan to change this one for a few years I want it to last.

Sorry to hijack the thread, but saves me creating another.

Would a Hiper 580W SLi be ok to power the following:

PhenomII 940 Quad
4GB Corsair
Asus M3A78 Mobo
Nvidia 8400GS
2xSATA HDD
1xDVD-RW
2xCase Fans.

Thanks.

I would imagine a 400w would run that

Good answer

Thanks again.

Hiper

"Bling-bling-to bang or not to?" brand.
So even though that ~150-170W configuration wouldn't cause any stress (which in no way prevents going off of PSU built to go that way) I would suggest investing those moneys to product whose maker aims for constant quality instead of maximized bling.

Like Corsair VX450.
