PSU help?

KaiserDragon · 23 Aug 2015 at 08:25

Hi, I bought a PSU when my old one failed, and had it installed in a repair shop, only trouble is I am planning on upgrading my GPU (from a Radeon 7850 to a Radeon 6990) and the wattage goes from 130 up to a rather large 375 and I was wondering would my current PSU be able to handle that? and this is where I run into the problem...

My case is an Antec 300 and the PSU is on the bottom and the sticker detailing the watts is facing the wrong side, I literally cant read it without dismantling my computer so I turn to you, to tell me what PSU I would need with the following spec:

i5 2500k 3.3GHz
Radeon HD 6990 4GB
8GB RAM
2x 500GB HDD

I think I have a 550w PSU but it might be as low as 500.

Do you know the model from the receipt when they install the psu?

A quality branded PSU from Sperflower, Antec and BeQuiet with 550w - 600w will be fine.

Unfortunately my PC broke during my university course so I had to repair it asap (can hardly study IT without a computer lol) so my dad paid for it at the time, and I paid him back gradually.

He doesn't keep receipts :/

EDIT: its a Coolmaster PSU which isn't highly recommended but I was desperate at the time lol.

I have added some option in my post above.

But ideally we need to see what model you have as some Coolermaster PSU were ok.

Edit: But as you mentioned it was not highly recommended then it might be worth changing

I wouldn't want to run that off a 550w psu. I would be looking to use at least a 650w unit but preferably a 750w psu for a 6990 system.

Problem solved! Friend who is upgrading the GPU is also upgrading his 750w PSU to a 1200w so his is going spare, he let me have both for £120 ^^

Thanks to all for the help though, it is appreciated!

Do you know the model and make of the PSU?

I did make mistake earlier. Forgot the 6990 is s dual GPU

That's old age creeping in.

KD, as RJC said, find out what make and model that 750w psu is first.

I should have checked your profile before posting that as I am 14 years older than you.
