I got a question about PSUs and performance.
I got this PC that needs to be upgraded a bit. It has a 530w power supply, intel quad core 2.83gz and the HD 4890.
But the 4890 is getting pretty old so I'm considering upgrading it into a 5870 i can get for a small amout of money.
With this upgrade, would a PSU-upgrade be necessarily too?
That link will tell you about what you need for your system. I would add about 50% on top of the low value it tells you rather than 50w like it does, but that is just my personal opinion and many around here differ from it.
I was going to say avoid it based on the brand but its made by seasonic so its good and the power on the 12V rail is consistent with a high quality 750W unit. So its more than you need but will work fine.
According to the eXtremes calculator, the 5870 lowers the total watt needed by 20w.
If I tried the 5870 with my stock PSU and then tried a new and better, would I see clear differences?
Now I start to wonder why I really need a new one :S
Take your chances with the same PSU if you like. Upgrading may not be completely mandatory in the short run, I would prefer a PSU in my computer that was meant for computers from this millennium, though.
I found a psu that meets my requirements and fits my need better than any previous psu, and I hope anyone could check this made by seasonic.
Silver Power SP-SS620M 620W PSU
I guess 620 fits my need much better than the 850
If it is Seasonic it is a top of the line product.
I tried to look up SP-SS620M online and verify that it is Seasonic, but I was unable to confirm that quickly. Many names were thrown around and Seasonic was only one of them. Tagan and many others were as well. I will just assume that it is.
