PSU upgrade from 300w to ...

Will I see any increase in performance if I upgrade my Dell Inspiron 620 PSU from 300w to 500w or more?

I have a decent mid level system, and have no real room to move upgrade wise:

- Samsung 830 128 GB SSD
- i5-2320
- 8gb DDR3
- Best video card I could get with the 300w limitation (fine for me, not a big gamer)
- 2 backup drives (1TB, 500 MB)

So yeah...would a power supply upgrade do anything?

More about upgrade 300w
  1. generally a 300w limitation on gpu only can go as far as a 7750 and very close to around there generally. chaning the psu basically doubles/triples the amount of $ you can spend on the gpu.(limited by how much you put into the psu and size of case)

    see any increase in performance if I upgrade my Dell Inspiron 620 PSU: No.

    IF your power supply was too small or failing you would see blue screen and system instability. A working power supply does not effect performance if it can deliver the right voltages (which are then further regulated by the MB, video card, etc). An undersized or failing PSU hurts stability and availability, not typically performance.

    edit: And you sir are very well prepared. "backup drives ". Most people (especially with SSDs) don't think about that untill way to late. gj.

    Would have guessed an 80W TDP HD7770 would run fine on a 300W PSU with modern 65w-95W processors. A 350 was plenty for Q6600 (105w) and HD5770 (108w).
  4. Okay...so I'll maintain the status quo. Ultimate question is this: With my current setup, what can be improved, aside from a new processor, etc...?

    "With my current setup, what can be improved"

    Nice system.
    Plenty of CPU
    HD7770 is plenty of video unless you change your mind about heavy gaming or unless you do cadcam. (lol, guess that proves HD7770 runs with 300w PSU and 95W CPU)
    8 GB plenty of memory
    Sound is fine. Some people swear by external USB DACs for good headphone. Never tried any.
    Samsung 830 has a good reliability reputation for SSD and is fast

    Assume you have a good monitor. I went 24" 1920X1200. I like the extra vertical space of 16:10 instead of 16:9.

    Have you ever tried a gaming mouse (e.g. deathadder) ? They slide nicely.

    I use a receiver as a monitor platform, and to power a pair of real speakers for audio. Like it.

    Not much else I can think of. My daughter wanted a tablet for her PC -- not sure what she uses it for. I have an external raid disk array for backup and movies -- a san digital unit with hardware raid 5. It's nice but not sure I'd spend the money again.
  6. Edited...thanks. Crossed my mind after I posted it...

    I have a nice 23" widescreen.

    So it sounds like I am done...for now. A few more years, and maybe I'll do a full build.

    Thanks everyone for the tips.
  7. Do you have that type of slot available for that card.
  8. They work pretty good i have one in my hp workstation.
  9. Yeah, at least 2...maybe 3.

    I'll consider it. Thanks!
