Yes.

Thanks

Edit: should be 620 Watt in op not 650.

How close would i be to exceeding it? I just want to make sure my psu is adequate.

At full load with something like Prime and Furmark I would say around 350w ~

Alasdairhurst · 4 Aug 2011 at 21:21

you should have plenty. the gpu draws the most power and that's about 200w full load, the cpu probably about 100w and hte rest probably add up to another 100w absolute max on top of that, so it adds up to about a maximum of 400w on 100% load for everything -( cpu and gpu)which it will never be just running on its own (without benchmarking). wattage is really overrated these days. you only need stuff over 750w in a multi gpu system with multiple cpus etc...
just make sure there is enough on the 12v rail as that is where most of hte power for the major components comes from. corsair psus are usually fine. it's the cheap ones that you have to watch out for - a 1000w cheap one is likely to just able to give as much power as a 650w quality one.

Definitely!

Thanks for the quick replies.

Radeon HD 6950 - On your average system the card requires you to have a 500 Watt power supply unit.

I didnt realise my psu was that good at the time of purchase back in 2007. wow ive really had it that long!

In conclusion, Corsair HX620W is one of the best power supplies you can find on the market, pleasing both average users and enthusiasts.

The only “bad thing” we can find about this product is its price.

I used the 620w for few years and the 520w without any issues

You have purchased once and it has saved you money later on

I always purchase fairly good quality kit.

My 8800gtx was bought in 2007 and played games perfectly well up until it got replaced a few months back. Its now being used by a mate. No one wanted it on mm so gave it to him for free. Served me well so only right to give it a good home

Gents,
I have a Corsair HX620w and its working fine for years and i am currently debating wether to replace it with a new more efficient PSU. Will a new PSU be more efficient than my existing HX620 Based upon the following spec:
Intel 2500K
MSI GTX560TI
1 SSD
2 HARDDRIVES
5 FANS IN total on case
1 CPU Fan

Any comments are appreciated

Cheers

Not really. Your PSU is fine. I have one with a 560ti and a 1055T overclocked that draws more power. It is 80+ efficiency.

thanks mate
