So I bought this underpowered second hand PC that I have been gradually upgrading.

When I saw the power supply(OCZGXS600) it said 600 watts,so I didn't think I would ever need to upgrade.I found out that it is from 2006: http://www.xbitlabs.com/articles/cases/display/atx-psu6_5.html

and know my pc doesn't need 700w. I dont know if a modern one with lower wattage would be better.Such as a Corsair Builder Series CX 500 Watt ATX/EPS 80 PLUS Bronze Power Supply Unit.

I will list my current specs.

GPU: Asus AMD Radeon HD 7770

CPU: Pentium Dual e2180 2GHZ

1440 p philips monitor

Razer lycosa keyboard

Logitech g500 mouse

I plan to upgrade to the Cpu to an fx8350 which is a big jump from the the ancient e2180(also have to change mobo and RAM(corsair veng 8gb))

I also am highly likely to get a second gpu and pair it with my current one and am looking from anywhere up to the £250 category for that upgrade.

So,do I need to upgrade the psu for future upgrades or is 600w from 2006 better than 500w from 2014,I really have no idea,please help.

Also if I do need a new psu please tell me which one I would need.

Thank You for reading.

I personally recommend having around 10-20% extra (above what 100% system load would use) when it comes to psu's. I would recommend using this calculator or a different one if you prefer: http://extreme.outervision.com/PSUEngine

 

If you intend to get a new psu, I would recommend a 600w or larger psu, a larger psu is a good thing for many reasons.

 

The psu will be more power efficient if it is not pushed to the max, pushing a psu to it's max rated wattage brings down efficiency. The power supply will only supply the power when needed so a 750w psu is not always using 750 watts.

 

The psu will last longer if it is not being pushed to it's limit.


If I am helping you with a problem and I have not responded within 48 hours please send me a PM.

Another point PSU's working or not do degrade over time, a failure can cost you your parts and hard work.


Honesty & Integrity Above All!

The 7770 has a power draw of about 80W. The 8350 rings in at 125W. Realistically, the 600 watt you have should be fine for a few more years. Though even if you go with two 7770's, a new 500W would be sufficient. Do yourself a favor though, and buy a quality power supply. The higher the quality, the better.
